101, 102, and 103.

It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

With continued reference to FIG. 2, a timing diagram of an embodiment of a page rendering system according to the present application is shown.

The page presentation system of the present embodiment includes: a target server and a client; the target server is used for receiving a page updating request sent by the client, wherein the page updating request comprises an identifier of a next field of a current field, the field is used for representing a gradient of presenting article information by the client, the starting time of purchase permission of an article associated with the article information corresponding to the identifier of the next field is obtained, the preloading time for loading the article information corresponding to the identifier of the next field in advance, the remaining time of the current time from the starting time and the article information to be presented are determined based on the current time, the starting time, the preset minimum preloading time for loading the article information corresponding to the identifier of the next field in advance, the preset maximum preloading time for loading the article information corresponding to the identifier of the next field in advance and the identifier of the next field, and the preloading time, the remaining time of the current time from the starting time and the article information to be presented are sent to the client, Remaining time and item information to be presented; and the client is used for sending a page updating request to the target server, receiving the preloading time, the remaining time and the to-be-presented article information returned by the target server, and presenting the to-be-presented article information based on the preloading time and the remaining time.

As shown in fig. 2, in step 201, the client sends a page update request to the target server.

Here, when the user performs a first-time purchase on the "killing-by-second" item, a refresh operation is performed on the current page presented on the client, for example, a click operation is performed on a refresh icon in the page presented on the client, a pull-down operation is performed on the current page, and the like; and after the client detects the refreshing operation of the user on the current page, the client can send the page updating request to the target server. The second killing is a new mode of on-line auction, and is a selling mode that a network seller issues some commodities with ultra-low prices and all buyers make a robbery purchase at the same time.

In step 202, the target server receives a page update request sent by the client.

Here, the target server may receive a page update request sent by the client, where a process of presenting the item information by the client may be divided into a plurality of stages, each stage is a ladder, and a field may be used to characterize the ladder in which the client presents the item information, for example, when the item information is presented in three stages, a field may be divided into a first field, a second field, and a third field, and the page update request may include an identifier of a field next to a current field, for example, when the current field is the first field, the page update request may include an identifier of the second field. The article information may also include service information, such as service information of a home service, service information of a mobile phone recharging service, and the like. The page update request is a request for obtaining information for page update by a client, and the information for page update may include, but is not limited to, at least one of the following: the method comprises the steps of loading the item information to be presented on the client, the preloading time for loading the item information corresponding to the identifier of the next field in advance and the remaining time (which can also be called 'countdown' time or the remaining time for killing the item from the second time of presenting the next field) from the starting time of the purchase authority of the item associated with the item information corresponding to the identifier of the next field at the current time. The preloading in a WEB page (WEB) may refer to loading some main contents in the WEB page before loading all contents of the WEB page, so as to reduce the waiting time of a user, where the preloading time may be a time when a client requests page information of the WEB page from a server in advance, so as to preload the page information.

In some optional implementations of this embodiment, the target server may synchronize the current Time by using a Network Time Protocol (NTP), so as to ensure that the Time of each system module (e.g., a module that processes a client request) in the target server is uniform, so as to ensure that each client has the right to purchase a next "kill second" item at the same Time as much as possible. The network time protocol is a protocol for synchronizing the time of a computer, which can synchronize the computer to its server or clock source (such as quartz clock, GPS, etc.), provide highly accurate time correction, and prevent malicious protocol attacks via encryption confirmation. The purpose of NTP is to provide accurate and robust time services in an out-of-order network environment.

Here, the target server may include a second killing service module, a cache module, a notification module, and a unified time center.

Here, the cache module may be configured to cache the item information corresponding to the identifier of the next session, and may cache the item information corresponding to the identifier of the next session in the Redis. The Redis is an open-source log-type and Key-Value-type database which is written by using ANSI C language, supports network, can be based on memory and can also be persistent.

Here, the notifying module may be configured to monitor a remaining time between a current time and a time when the "killing-by-second" item of the next session is presented, write item information corresponding to an identifier of the next session into the cache module from a database before the time when the current time is reached, and notify the killing-by-second service module to obtain item information corresponding to the identifier of the next session. As an example, the notification module may notify the second killing service module to obtain the item information corresponding to the identifier of the next session through a Zookeeper, where the Zookeeper is a distributed, open-source distributed application coordination service, which is software that provides a consistency service for the distributed application.

Here, the session killing service module may be configured to receive the notification sent by the notification module and process a request sent by the client. After receiving the notification sent by the notification module, the seckilling service module may obtain the item information corresponding to the identifier of the next session from the cache module and store the item information in a local cache, and calculate the remaining time and the pre-loading time of the seckilling item from the presentation of the next session according to a request sent by the client, and finally may return the item information, the remaining time and the pre-loading time to the client.

Here, the unified time center may be configured to ensure time unification of all machines in the seckilling service module through a network time protocol, so as to ensure that each client has a purchase right for the next "seckilling" item at the same time.

Here, the notification module may first unify the time of the seckilling service module through a network time protocol; then, the notification module may monitor the remaining time for killing the article in seconds until the next time is presented, and when the remaining time is less than a time threshold for writing data into the cache module, may obtain article information corresponding to the identifier of the next time from the database and write the article information into the cache module; then, the notification module can notify the second killing service module to obtain the item information corresponding to the identifier of the next session through the Zookeeper; after receiving the notification sent by the notification module, the sbd service module may read the item information corresponding to the identifier of the next field from the cache module and write the item information into a local cache. By the multi-level caching method, the item information can be updated to the Redis cache module before the item information is switched to kill the item in seconds, and the Zookeeper informs the server to pull the data in the Redis cache module to the local cache, so that the access to the database is reduced, the pressure on the database is relieved, and the access speed to the data is improved.

In step 203, the target server acquires the start time of the purchase right of the item associated with the item information corresponding to the identifier of the next session.

Here, after receiving the identifier of the next session in step 202, the target server may obtain the start time of the purchase authority of the item associated with the item information corresponding to the identifier of the next session, for example, the start time at which the user may purchase the "kill by second" item of the next session, which may also be referred to as "kill by second" start time.

In step 204, the target server determines a pre-loading time for loading the item information corresponding to the identifier of the next session in advance, a remaining time of the current time from the start time, and the item information to be presented, based on the current time, the start time, a preset minimum pre-loading time for loading the item information corresponding to the identifier of the next session in advance, a preset maximum pre-loading time for loading the item information corresponding to the identifier of the next session in advance, and the identifier of the next session.

Here, the target server may set in advance a maximum preloading time for loading in advance the article information corresponding to the identifier of the next session and a minimum preloading time for loading in advance the article information corresponding to the identifier of the next session. As an example, when the maximum preloading time is 3 minutes, the client may load the item information 3 minutes before the start of the second killing at the earliest time; when the minimum preloading time is 1 minute, the client may load the item information at the latest 1 minute before the start of the "second kill".

Here, the target server may determine, based on the current time, the start time acquired in step 203, the maximum preload time, the minimum preload time, and the identifier of the next session, a preload time for loading in advance the item information corresponding to the identifier of the next session, a remaining time of the current time from the start time, and item information to be presented.

Here, the target server may determine a remaining time of the current time from the start time based on the current time and the start time; the target server may determine the preload time based on the remaining time, the maximum preload time, and the minimum preload time; the target server may determine the item information to be presented based on the remaining time, the preload time, and the identifier of the next session.

In some optional implementations of this embodiment, the target server may first determine a difference between the start time and the current time, and use the difference as a remaining time between the current time and the start time; then, it may be determined whether the remaining time is greater than the maximum preload time, and if it is determined that the remaining time is greater than the maximum preload time, any time may be selected as the preload time within an interval greater than the minimum preload time and less than the maximum preload time. As an example, when the starting time having the purchase authority for the next session of the "second kill" item is 12 points, the current time is 11 points and 56 minutes, the maximum preload time is 3 minutes, and the minimum preload time is 1 minute, then the remaining time from which the next session of the "second kill" item can be purchased is 4 minutes, at which time it is determined that the remaining time 4 minutes is greater than the maximum preload time by 3 minutes, then the preload time may be set to any time within an interval that is less than the maximum preload time by 3 minutes and greater than the minimum preload time by 1 minute.

In some optional implementation manners of this embodiment, if it is determined that the remaining time is less than or equal to the maximum preloading time, it may be further determined whether the remaining time is greater than the minimum preloading time, and if it is determined that the remaining time is greater than the minimum preloading time, any time may be selected as the preloading time within an interval greater than the minimum preloading time and less than the remaining time. As an example, when the starting time having the purchase right for the next time of the "second kill" item is 12 points, the current time is 11 points 58 minutes, the maximum preload time is 3 minutes, and the minimum preload time is 1 minute, the remaining time from which the next time of the "second kill" item can be purchased is 2 minutes, at which time, it is determined that the remaining time 2 minutes is less than the maximum preload time 3 minutes and greater than the minimum preload time 1 minute, and the preload time may be set to any time within an interval of greater than the minimum preload time 1 minute and less than the above-mentioned remaining time 2 minutes.

In some optional implementation manners of this embodiment, if it is determined that the remaining time is less than the minimum preloading time, the preloading time may be set to a preset time value, for example, the preloading time is set to 0, the client may not load the item information in advance, and when the remaining time is 0, the client may directly request the server for the item information corresponding to the identifier of the next session.

In some optional implementation manners of this embodiment, the page update request may further include an identifier of a current session, and the target server may determine whether the start time is less than or equal to the current time, and if it is determined that the start time is less than or equal to the current time (the target server has the right to purchase an "kill second" item of a next session), may replace the item information corresponding to the identifier of the current session with the item information corresponding to the identifier of the next session, and use the replaced item information as the item information to be presented. As an example, when the starting time having the purchase right for the "second killing" item in the next session is 12 points, and the current time is 12 points and 1 minute, the current time is greater than the starting time, and the item information corresponding to the identifier in the next session is used to replace the item information corresponding to the identifier in the current session.

In some optional implementations of this embodiment, if the target server determines that the start time is greater than the current time (without the right to purchase the "kill of second" item of the next session), it may further determine whether the remaining time is greater than the preloading time and the item information corresponding to the identifier of the next session exists in the cache of the target server, and if it is determined that the remaining time is greater than the preloading time and the item information corresponding to the identifier of the next session exists in the cache of the target server, acquire the item information corresponding to the identifier of the next session from the cache of the target server and use the acquired item information as the item information to be presented.

In some optional implementation manners of this embodiment, if it is determined that the remaining time is less than or equal to the preloading time or the item information corresponding to the identifier of the next session does not exist in the cache of the target server, the item information corresponding to the identifier of the current session may be acquired as the item information to be presented.

In step 205, the target server sends the client the preloaded time, the remaining time and the item information to be presented.

Here, the target server may send the preloading time, the remaining time, and the information about the article to be presented, which are determined in step 204, to the client, so that the client presents the information about the article to be presented based on the preloading time, the remaining time, and the information about the article to be presented. When the article information to be presented is article information corresponding to the identifier of the next session, the target server can send the preloading time, the remaining time and the article information to be presented to the client in batches; when the item information to be presented is the item information corresponding to the identifier of the current session, the target server may send the preloading time, the remaining time, and the item information to be presented to the client at one time.

In some optional implementations of this embodiment, when the article information to be presented is article information corresponding to an identifier of a next session, the target server may first send the preload time and the remaining time to the client, where the client may determine whether the received preload time is the time value (e.g., 0), if it is determined that the preload time is not the time value, it may further determine whether the current remaining time is equal to the preload time, and if the current remaining time is equal to the preload time, the client may send an article information acquisition request for acquiring the article information corresponding to the identifier of the next session to the target server; and then, when the target server receives the item information acquisition request sent by the client, sending item information corresponding to the identifier of the next field to the client so that when the client determines that the current remaining time is 0, the item information corresponding to the identifier of the next field is presented. The client may determine the current remaining time based on the current time, the remaining time, and the time when the target server return remaining time is received.

In step 206, the client receives the preloading time, the remaining time and the information of the articles to be presented, which are returned by the target server.

Here, the client may receive the preload time, the remaining time, and the item information to be presented, which are returned by the target server. The pre-loading time, the remaining time and the information of the articles to be presented can be returned by the target server in batches or at one time.

In step 207, the client presents the item information to be presented based on the preload time and the remaining time.

Here, the client may determine a start time having an authority to purchase the "killing per second" item of the next session based on the remaining time and the time when the target server returns the remaining time, and may present item information corresponding to the identifier of the next session when the current time reaches the start time.

With further reference to FIG. 3, a timing diagram of yet another embodiment of a page rendering system according to the present application is shown.

As shown in fig. 3, in step 301, the client sends a page update request to the target server.

In step 302, the target server receives a page update request sent by the client.

In step 303, the target server acquires the start time of the purchase right of the item associated with the item information corresponding to the identifier of the next session.

In step 304, the target server determines a pre-loading time for loading the item information corresponding to the identifier of the next session in advance, a remaining time of the current time from the start time, and the item information to be presented, based on the current time, the start time, a preset minimum pre-loading time for loading the item information corresponding to the identifier of the next session in advance, a preset maximum pre-loading time for loading the item information corresponding to the identifier of the next session in advance, and the identifier of the next session.

Here, the operation of step 301-304 is substantially the same as the operation of step 201-204, and is not described herein again.

In step 305, the target server sends the preload time and the remaining time to the client.

Here, after the target server determines the item information to be presented, it may be determined whether the item information to be presented is the item information corresponding to the identifier of the next session, and if the item information corresponding to the identifier of the next session, the target server may first send the preloading time and the remaining time determined in step 304 to the client.

In step 306, the client receives the preload time and the remaining time returned by the target server.

Here, the client may receive the preload time and the remaining time returned by the target server.

In step 307, the client determines whether the preload time is a preset time value.

Here, the client may determine whether the preloading time is a preset time value (determine whether a preloading operation on the item information is required), where the time value may be set by the target server in response to determining that the remaining time is less than or equal to the minimum preloading time, for example, the time value may be 0; if not, step 308 may be performed.

In step 308, the client determines whether the current remaining time is equal to the preload time.

Here, the client may determine the current remaining time based on the current time, the above remaining time, and the time when the return remaining time of the target server is received. The client can add the time when the target server returns the remaining time to obtain the starting time, and subtract the current time from the obtained starting time to obtain the current remaining time; the client can also obtain a time difference by subtracting the time when the target server returns the remaining time from the current time, and then obtain the current remaining time by subtracting the time difference from the remaining time.

Here, when it is determined in step 307 that the preloading time is not the preset time value, the client may determine whether the current remaining time is equal to the preloading time (whether the current time reaches the preloading time for preloading the item information), and if so, may perform step 309.

In step 309, the client sends an item information acquisition request for acquiring item information corresponding to the identifier of the next session to the target server.

Here, when it is determined that the current remaining time is equal to the preloading time (the current time reaches the preloading time for preloading the item information), the client may send an item information acquisition request for acquiring the item information corresponding to the identifier of the next session to the target server.

In step 310, the target server receives an item information acquisition request sent by the client.

Here, the target server may receive an item information obtaining request sent by the client, and obtain item information corresponding to the identifier of the next session in a cache of the target server.

In step 311, the target server sends the item information corresponding to the identifier of the next session to the client.

Here, after the target server acquires the item information corresponding to the identifier of the next session in the cache, the target server may transmit the acquired item information corresponding to the identifier of the next session to the client.

In step 312, the client receives the item information corresponding to the identifier of the next session returned by the target server.

Here, the client may receive the item information corresponding to the identifier of the next session returned by the target server.

In step 313, the client determines whether the current remaining time is equal to 0.

Here, the client may determine whether the current remaining time is 0 (whether the current time reaches the start time of the purchase right of the item associated with the item information corresponding to the identifier of the next session), and if so, may perform step 314.

In step 314, the client presents the item information to be presented.

Here, when it is determined that the current remaining time is 0 (the current time reaches the start time), the client may present the item information corresponding to the identifier of the next session received in step 312.

FIG. 4 shows a flow 400 of one embodiment of a page rendering method according to the present application. The page presentation method comprises the following steps:

step 401, receiving a page update request sent by a client.

In this embodiment, an electronic device (for example, a server shown in fig. 1) on which the page presentation method operates may receive, through a wired connection manner or a wireless connection manner, a page update request sent by a client, where a process of presenting item information by the client may be divided into a plurality of stages, each stage is a ladder, a field may be used to characterize the ladder in which the client presents item information, and the page update request may include an identifier of a field next to a current field. The article information may also include service information, for example, server information of a nail beauty service, and the like.

In this embodiment, when a user buys a second killing item, the user performs a refresh operation on a current page presented on the client; and after the client detects the refreshing operation of the user on the current page, the client can send the page updating request to the electronic equipment. The second killing is a new mode of on-line auction, and is a selling mode that a network seller issues some commodities with ultra-low prices and all buyers make a robbery purchase at the same time.

Step 402, obtaining the starting time of the purchase authority of the item associated with the item information corresponding to the identifier of the next field.

In this embodiment, after receiving the identifier of the next session in step 401, the electronic device may obtain a start time of the purchase authority of the item associated with the item information corresponding to the identifier of the next session, where the start time may also be referred to as a start time of the purchase of the "killing by seconds" item of the next session by the user or a "killing by seconds" start time.

And step 403, determining the preloading time for loading the article information corresponding to the identifier of the next field in advance, the remaining time of the current time from the start time and the article information to be presented based on the current time, the start time, the preset minimum preloading time for loading the article information corresponding to the identifier of the next field in advance, the preset maximum preloading time for loading the article information corresponding to the identifier of the next field in advance and the identifier of the next field.

In this embodiment, the electronic device may preset a maximum preloading time for loading in advance the article information corresponding to the identifier of the next session, and a minimum preloading time for loading in advance the article information corresponding to the identifier of the next session.

In this embodiment, the electronic device may determine, based on the current time, the start time, the maximum preload time, the minimum preload time, and the identifier of the next session, a preload time for loading in advance the item information corresponding to the identifier of the next session, a remaining time of the current time from the start time, and item information to be presented.

In this embodiment, the electronic device may determine the remaining time between the current time and the start time based on the current time and the start time; the electronic device may determine the preload time based on the remaining time, the maximum preload time, and the minimum preload time; the electronic device may determine the item information to be presented based on the remaining time, the preload time, and the identifier of the next session.

In some optional implementations of this embodiment, the electronic device may first determine a difference between the start time and the current time, and use the difference as a remaining time between the current time and the start time; then, it may be determined whether the remaining time is greater than the maximum preload time, and if it is determined that the remaining time is greater than the maximum preload time, any time may be selected as the preload time within an interval greater than the minimum preload time and less than the maximum preload time.

In some optional implementation manners of this embodiment, if it is determined that the remaining time is less than or equal to the maximum preloading time, it may be further determined whether the remaining time is greater than the minimum preloading time, and if it is determined that the remaining time is greater than the minimum preloading time, any time may be selected as the preloading time within an interval greater than the minimum preloading time and less than the remaining time.

In some optional implementation manners of this embodiment, if it is determined that the remaining time is less than or equal to the minimum preloading time, the preloading time may be set to a preset time value, for example, the preloading time is set to 0, the client may not load the item information in advance, and when the remaining time is 0, the client may directly request the server for the item information corresponding to the identifier of the next session.

In some optional implementation manners of this embodiment, the page update request may further include an identifier of a current session, and the electronic device may determine whether the start time is less than or equal to the current time, and if it is determined that the start time is less than or equal to the current time, may replace the item information corresponding to the identifier of the current session with the item information corresponding to the identifier of a next session, and use the replaced item information as the item information to be presented.

In some optional implementations of this embodiment, if the electronic device determines that the start time is greater than the current time, it may further determine whether the remaining time is greater than the preload time and the item information corresponding to the identifier of the next session exists in the cache of the electronic device, and if it is determined that the remaining time is greater than the preload time and the item information corresponding to the identifier of the next session exists in the cache of the electronic device, it may acquire the item information corresponding to the identifier of the next session from the cache of the electronic device and use the acquired item information as the item information to be presented.

Step 404, sending the preloading time, the remaining time and the article information to be presented to the client for the client to present the article information to be presented based on the preloading time, the remaining time and the article information to be presented.

In this embodiment, the electronic device may send the pre-loading time, the remaining time, and the to-be-presented item information determined in step 403 to a client, so that the client presents the to-be-presented item information based on the pre-loading time, the remaining time, and the to-be-presented item information. When the article information to be presented is article information corresponding to the identifier of the next session, the electronic device can send the preloading time, the remaining time and the article information to be presented to the client in batches; when the item information to be presented is the item information corresponding to the identifier of the current session, the electronic device may send the preloading time, the remaining time, and the item information to be presented to the client at one time.

In some optional implementations of this embodiment, when the article information to be presented is article information corresponding to an identifier of a next session, the electronic device may first send the preload time and the remaining time to a client, where the client may determine whether the received preload time is the time value, if it is determined that the preload time is not the time value, then further determine whether the current remaining time is equal to the preload time, and if the current remaining time is equal to the preload time, the client may send an article information acquisition request for acquiring the article information corresponding to the identifier of the next session to the electronic device; then, when the electronic device receives the item information acquisition request sent by the client, the electronic device may send item information corresponding to the identifier of the next session to the client, so that when the client determines that the current remaining time is 0, the item information corresponding to the identifier of the next session is presented. The client may determine the current remaining time based on the current time, the remaining time, and the time when the target server return remaining time is received.

The method provided by the above embodiment of the application, by responding to a received page update request including an identifier of the next field sent by a client, sends the client a pre-loading time for loading in advance the item information corresponding to the identifier of the next field, a remaining time from a current time to a starting time of a purchase right of an item associated with the item information corresponding to the identifier of the next field, and the item information to be presented, so that the client loads the item information to be presented in advance based on the pre-loading time, and automatically presents the item information to be presented based on the remaining time, thereby reducing the pressure of a network and a server, and improving the timeliness of page switching.

With further reference to FIG. 5, a flow 500 of yet another embodiment of a page rendering method is shown. The process 500 of the page rendering method includes the following steps:

step 501, a page update request is sent to a target server.

In this embodiment, an electronic device (for example, the terminal device shown in fig. 1) on which the page rendering method operates may send the above-mentioned page update request to the target server. When a user buys a second killing object, refreshing a current page presented on the electronic equipment; after the electronic device detects that the user performs a refresh operation on the current page, the page update request may be sent to a target server.

Step 502, receiving the preloading time for loading the item information corresponding to the identifier of the next session in advance, the remaining time from the starting time of the purchase authority of the item associated with the item information corresponding to the identifier of the next session, and the item information to be presented, which are returned by the target server.

In this embodiment, the electronic device may receive, from the target server, a preloaded time for loading in advance the item information corresponding to the identifier of the next session, a remaining time between the current time and a start time of a purchase right of an item associated with the item information corresponding to the identifier of the next session, and the item information to be presented. The preloading time, the remaining time and the information of the articles to be presented can be returned by the target server in batches or at one time.

In some optional implementation manners of this embodiment, the item information to be presented includes item information corresponding to an identifier of a next session, and the electronic device may first receive the preload time and the remaining time returned by the target server; then, it may be determined whether the preloading time is a preset time value, where the time value may be set by the target server in response to determining that the remaining time is less than or equal to the minimum preloading time, and if it is determined that the preloading time is not the time value and the current remaining time is equal to the preloading time, an item information acquisition request for acquiring item information corresponding to the identifier of the next session may be sent to the target server; finally, the item information corresponding to the identifier of the next session returned by the target server can be received.

And 503, presenting the item information to be presented based on the preloading time and the remaining time.

In this embodiment, the electronic device may present the item information to be presented based on the preloading time and the remaining time. The electronic device may determine a start time having a right to purchase a "killing per second" item of a next session based on the remaining time and a time when the target server returns the remaining time, and when a current time reaches the start time, the electronic device may present item information corresponding to an identifier of the next session.

In some optional implementation manners of this embodiment, the electronic device may determine the current remaining time based on the current time, the remaining time, and the time when the target server return remaining time is received. The electronic equipment can add the time when the target server returns the remaining time and the remaining time to obtain the starting time, and subtract the current time from the obtained starting time to obtain the current remaining time; the electronic equipment can also obtain a time difference by subtracting the time when the target server returns the remaining time from the current time, and then obtain the current remaining time by subtracting the time difference from the remaining time. The electronic device may determine whether the current remaining time is 0, and if so, may present the item information corresponding to the identifier of the next session.

In this embodiment, when the received to-be-presented item information is item information corresponding to an identifier of a current session, the electronic device may immediately present the item information corresponding to the identifier of the current session.

According to the method provided by the embodiment of the application, the page updating request is sent to the target server, the preloading time, the remaining time and the article information to be presented, which are returned by the target server, are received, and then the article information to be presented is presented based on the preloading time and the remaining time, so that the target server is accessed in advance through the preloading technology to obtain the article information to be presented, the pressure of a network and a server is relieved, and the timeliness of page switching is improved.
