Description
Technical Field
The present application relates to the field of computer communications, and in particular, to a server, a data processing method, an apparatus, and a medium.
Background
In the prior art, a DNS server stores a correspondence between an analysis result such as an IP address and a domain name, and can determine a target analysis result corresponding to the domain name carried in a received analysis request according to the correspondence between the analysis result and the domain name, thereby feeding back the target analysis result to an intelligent device of a user.
In an actual application scenario, fig. 1 is a schematic view of a scenario in which an existing server processes a domain name. As shown in fig. 1, the intelligent device of the user initiates an analysis request, for example, an analysis request for querying an IP address of www.example.com, to a server provided by a network operator or other public servers, and after receiving the analysis request, the server obtains a domain name carried in the analysis request, and queries whether an analysis result corresponding to the domain name is stored according to the domain name. If the analysis result corresponding to the domain name is stored and the validity period corresponding to the analysis result is not due, the server sends the acquired analysis result to the intelligent equipment; otherwise, the resolution request is forwarded to other preconfigured servers, such as a recursive DNS server, iteratively forwarded to the root server through other DNS servers, and iteratively forwarded to authority servers of each level through other DNS servers, so as to obtain resolution results of the domain name carried in the resolution request by other servers, the obtained resolution results are sent to the intelligent device, and the domain name and the resolution result corresponding to the domain name are locally cached, so that when the resolution request carrying the domain name is received again in the following process, the cached resolution result corresponding to the domain name can be directly sent to the intelligent device, and the response efficiency to the intelligent device is improved.
When the other servers receive the resolution result again, the server determines that the resolution result corresponding to the domain name exceeds the valid period, and determines that the resolution result corresponding to the domain name is invalid, and needs to query the resolution result corresponding to the domain name from the other servers again, and sends the resolution result corresponding to the domain name sent by the other servers to the intelligent device.
For the processing method, when the resolution result corresponding to a certain domain name cached by the server expires and other servers fail, the server cannot acquire the resolution result of the domain name fed back by other servers in time and waits for the resolution result of the domain name fed back by other servers all the time, so that the server cannot respond to the resolution request in time, and the response efficiency of the server and the user experience are reduced.

Detailed Description
In order to improve the response efficiency of a server to an analysis request and improve user experience, the application provides the server, a data processing method, a data processing device and a medium.
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In actual use, the user's smart device initiates a resolution request to a server provided by the network operator or otherwise public, for example, a resolution request to query www.example.com for the IP address. After receiving an analysis request for analyzing a certain domain name sent by the intelligent device, the server performs corresponding processing on the analysis request to acquire domain name information carried in the analysis request. In order to realize the fast forwarding of the resolution results corresponding to some domain names to the intelligent device, the server pre-caches the resolution results corresponding to some domain names and the validity periods corresponding to the resolution results, after the resolution results in the resolution request are obtained, the domain name is matched with the domain name in which the resolution results are cached, when the matched domain name exists, whether the validity period corresponding to the target resolution result corresponding to the matched domain name expires is determined, and if the validity period corresponding to the target resolution result expires is determined, the resolution results can be sent to other servers. And determining whether to directly send the target analysis result according to whether to receive the analysis result of the domain name sent by other servers within a preset first time period.
Fig. 2 is a schematic diagram of a data processing process provided in some embodiments of the present application, where the process includes:
s201: receiving a first analysis request, and acquiring domain name information carried in the first analysis request.
In the application, the data processing method provided by the application is applied to a server.
In the actual application process, when a user wants to access a certain website through a certain registered domain name, the user can acquire the IP address of a certain page of the certain website by inputting the domain name, so that the purpose of accessing the certain website is achieved. After receiving the domain name input by the user, the intelligent device generates a corresponding first resolution request according to the domain name, and sends the generated first resolution request to a server provided by a network operator or other public servers. And after receiving the first resolution request, the subsequent server acquires the domain name information carried in the first resolution request through corresponding processing. Then, based on the data processing method provided by the application, the information of the domain name is correspondingly processed, so that the first resolution request is responded.
The first analysis request received by the server may be an analysis request sent by the smart device, or an analysis request sent by the smart device and forwarded by a subordinate server.
S202: and if the local cache is determined to have the target analysis result corresponding to the domain name and the validity period corresponding to the target analysis result is expired, forwarding the first analysis request to other servers.
S203: and determining that the domain name resolution results sent by the other servers are not received within a preset first time length, and sending the target resolution results.
In an actual application scenario, the situation of modifying the resolution result corresponding to the domain name occurs relatively rarely, for example, the IP address corresponding to a certain domain name is modified, so that the resolution result of the domain name obtained by re-querying another server is the same as that obtained before in most cases. Therefore, in order to facilitate the subsequent intelligent device to obtain the resolution result of the accessed domain name in time, the server may cache the received resolution result of a certain domain name sent by another server, so that when the second resolution request carrying the domain name is received again in the subsequent process, the locally cached resolution result of the domain name is directly sent, and the efficiency of responding to the resolution request is improved.
In order that a server does not continuously send a target analysis result corresponding to a domain name cached locally, namely an incorrect analysis result is sent when an analysis result of the domain name changes, the intelligent device is influenced to access subsequent services, and when other servers send the analysis result of any domain name to the server, the other servers also send a valid period corresponding to the analysis result. After receiving the resolution result of the domain name and the valid period corresponding to the resolution result, the server caches the resolution result of the domain name, the time for receiving the resolution result and the valid period corresponding to the resolution result, and determines whether the valid period corresponding to the resolution result of the domain name is due according to the time for receiving the resolution request and the valid period corresponding to the resolution result when the subsequent intelligent device requests the resolution result of the domain name, so that the server can forward the received first resolution request to other servers when the valid period corresponding to the resolution result is due, and update the locally cached resolution result corresponding to the domain name according to the resolution result of the domain name sent by other servers.
The method for determining whether the valid period corresponding to the resolution result of the domain name is due according to the time when the resolution request is received and the valid period corresponding to the resolution result comprises the following steps:
the first method starts timing when the analysis result is received. And subsequently judging whether the time length recorded by the timer when the analysis request is received is greater than the valid period corresponding to the analysis result, and determining whether the valid period corresponding to the analysis result of the domain name is expired. If so, determining that the validity period corresponding to the resolution result of the domain name is expired; otherwise, determining that the validity period corresponding to the resolution result of the domain name is not due.
And secondly, when the analysis result is received, counting down from the validity period corresponding to the analysis result. And subsequently judging whether the remaining time recorded by the timer is 0 or not when the analysis request is received, and determining whether the valid period corresponding to the analysis result of the domain name is expired or not. If so, determining that the validity period corresponding to the resolution result of the domain name is expired; otherwise, determining that the validity period corresponding to the resolution result of the domain name is not due.
And thirdly, when the analysis result is received, determining an effective time range according to the current time for receiving the analysis result and the effective period corresponding to the analysis result. And subsequently judging whether the time when the resolution request is received is within the valid time range, and determining whether the valid period corresponding to the resolution result of the domain name is due. If so, determining that the validity period corresponding to the resolution result of the domain name is expired; otherwise, determining that the validity period corresponding to the resolution result of the domain name is not due.
For the above method, once other servers have a fault or deny the server access, the server is easily caused to wait for other servers to feed back the resolution result of the domain name, so that the first resolution request of the user cannot be continuously responded, and further the access of the subsequent service of the user is affected.
In a possible implementation manner, in order to respond to the first resolution request in time, after the information of the domain name carried in the first resolution request is acquired, the domain name is matched with the domain name in which the resolution result is cached, when the matched domain name exists, whether the valid period corresponding to the target resolution result corresponding to the matched domain name expires is determined, if the valid period corresponding to the target resolution result expires is determined, the target resolution result is sent, and the first resolution request is forwarded to other servers, so that the target resolution result and the valid period corresponding to the target resolution result which are cached locally at present are updated.
Through the method, although the server can respond to the first resolution request of the user in time, and the target resolution result locally cached by the server is correct under most conditions, once the resolution result of a certain domain name changes and other servers can respond normally, the server directly sends the target resolution result locally cached corresponding to the domain name, so that the intelligent device can perform subsequent service processing according to the target resolution result, and subsequent service access of the user is influenced. Therefore, in order to respond to the first resolution request in time and ensure the accuracy of the resolution result of the domain name sent to the intelligent device as much as possible, in the present application, after it is determined that a target resolution result corresponding to a certain domain name is cached locally and the validity period corresponding to the target resolution result has expired, the first resolution request is forwarded to another server, and according to whether the resolution result of the domain name sent by another server is received within a preset first time period, it is determined how to respond to the first resolution request of the intelligent device.
In a specific implementation process, if it is determined that the domain name resolution result sent by the other server is not received within a preset first time period, which indicates that network delay may occur or other servers fail, the target resolution result is sent first.
If the first analysis request is sent by the intelligent equipment, when the analysis result of the domain name sent by the other server is determined not to be received within a preset first time period, the target analysis result is sent to the intelligent equipment; and if the first analysis result is forwarded by the lower-level server, when determining that the analysis result of the domain name sent by the other server is not received within a preset first time period, sending the target analysis result to the lower-level server.
S204: and if the domain name resolution results sent by the other servers are determined to be received within a preset first time period, sending the domain name resolution results.
In a possible implementation manner, in order to ensure accuracy of the server responding to the first resolution request, in the present application, if it is determined that the resolution result of the domain name sent by another server is received within a preset first time period, which indicates that the other server is currently working normally, in order to ensure accurate response to the first resolution request, the received resolution result of the domain name sent by the other server is sent.
If the first resolution request is sent by the intelligent equipment, determining that the resolution result of the domain name sent by the other server is received within a preset first time period, and sending the resolution result of the domain name to the intelligent equipment; and if the first resolution result is forwarded by the lower-level server, determining that the resolution result of the domain name sent by the other server is received within a preset first time period, and sending the resolution result of the domain name to the lower-level server.
In the present application, when the first time duration is set, the first time duration may be determined empirically, or different values may be set according to different scenes. If it is desired to ensure the efficiency of the server responding to the first resolution request, the preset first duration may be set to be shorter, and if it is desired to avoid that the resolution result of the domain name normally sent by another server cannot be sent due to the too short first duration, the preset first duration may be set to be longer. Preferably, the time length of the normal interaction between each other server and the server can be set according to statistics.
The server transmits the received first analysis request to other servers under the condition that the target analysis result corresponding to the domain name carried in the received first analysis request is determined to be locally cached and the validity period corresponding to the target analysis result is determined to be due, and the cached target analysis result is transmitted first after the analysis result of the domain name transmitted by other servers is determined not to be received within the preset first time period, so that the time consumed by waiting for other servers to transmit the analysis result of the domain name is avoided, the first analysis request can be responded in time within the preset first time period, and the response efficiency of the server and the user experience are improved.
In order to accurately determine whether another server may fail, on the basis of the foregoing embodiment, in the present application, determining that the resolution result of the domain name sent by the other server is not received within a preset first time period includes:
receiving failure response information sent by the other servers within the preset first time period; or
Response information sent by other servers is not received within the preset first duration, and the response information is success response information or failure response information, wherein the success response information carries the domain name resolution result.
In an actual application scenario, conditions such as network delay and other server failures may occur, so that the server cannot receive the resolution result of the domain name sent by the other server within a preset first time period. Specifically, when network delay occurs, communication delay between other servers and the server may be caused, so that the server cannot receive the resolution result of the domain name sent by the other server within a preset first time period; when a network fault occurs, communication connection cannot be established between other servers and the server, so that the server cannot receive the resolution result of the domain name sent by other servers within a preset first time period; when other servers fail, the server may not receive the resolution result of the domain name sent by other servers within a preset first time period or receive failure response information sent by other servers, such as servfile, release, and the like. Based on this, in the present application, the server determines that the resolution result of the domain name sent by another server is not received within the preset first duration, including the following cases:
in the first situation, if failure response information sent by other servers is received within a preset first time period, which indicates that other servers may have a fault and cannot be recovered temporarily, it is determined that an analysis result of a domain name sent by other servers is not received within the preset first time period.
And in the second case, if the response information sent by the other server is not received within the preset first time period, that is, the successful response information or the failed response information sent by the other server is not received within the preset first time period, it is determined that the resolution result of the domain name sent by the other server is not received within the preset first time period.
The successful response information carries the resolution result of the domain name, such as NOERROR, nxdmoin, and the like.
And when determining that the domain name resolution results sent by other servers are not received within the preset first time period based on the above situation, the server directly sends the locally cached target resolution results.
Further, network delay may occur, or the first resolution request sent by the server cannot be processed within a preset first time period due to more processing tasks of other servers, so that the server cannot receive the resolution result of the domain name sent by other servers within the preset first time period, and after the target resolution result of the local cache is sent, the resolution result of the domain name sent by other servers is received. In order to ensure the accuracy of the response of the server to the first resolution request when the intelligent device subsequently performs the first resolution request on the domain name again, after the server sends the locally cached target resolution result, if the resolution result of the domain name sent by another server is received, the locally cached target resolution result corresponding to the domain name is updated according to the currently received resolution result of the domain name sent by another server. Specifically, after sending the target analysis result, the method further includes:
and when the domain name resolution results sent by the other servers are received, updating the target resolution result according to the resolution results.
In an actual application scenario, when sending the domain name resolution result to the server, the other servers generally send the valid period corresponding to the resolution result to the server, so that the server can monitor the update time of the resolution result and request the resolution result of the domain name from the other servers in time, thereby updating the locally cached target resolution result according to the domain name resolution result sent by the other servers and improving the accuracy of the subsequent response to the domain name resolution request. Therefore, in the present application, after receiving the resolution result corresponding to the domain name and the validity period corresponding to the resolution result, the target resolution result is updated according to the resolution result, and the validity period corresponding to the target resolution result is updated according to the validity period corresponding to the resolution result. Specifically, the receiving the resolution result of the domain name sent by the other server includes:
receiving an analysis result corresponding to the domain name and an effective period corresponding to the analysis result;
the updating the target analysis result according to the analysis result comprises:
and updating the target analysis result according to the analysis result, and updating the validity period corresponding to the target analysis result according to the validity period corresponding to the analysis result.
In order to update the target resolution result in time, on the basis of the foregoing embodiments, in this application, the receiving the resolution result of the domain name sent by the other server includes:
receiving the domain name resolution results sent by the other servers within a preset second time period; or
And determining that the analysis results of the domain name sent by the other servers are not received within a preset second time, and sending the first analysis request to the other servers according to a preset time interval until the analysis results of the domain name sent by the other servers are received.
In an actual application scenario, since network delay may occur or tasks processed by other servers at present are more, the first resolution request cannot be processed within a preset first time period, but when the network does not delay or other servers process the first resolution request, the server does not need to send the first resolution request to other servers again, and may also receive resolution results of the domain name sent by other servers. Therefore, in order to avoid that the server frequently forwards the first parsing request to other servers, in the application, a second duration is preset. The server may determine whether the resolution result of the domain name sent by the other server is received within a second preset time period after the server does not receive the resolution result of the domain name sent by the other server within the preset first time period. And if the analysis result of the domain name sent by other servers is received within a second preset time, directly updating the target analysis result of the local cache according to the received analysis result of the domain name.
In a possible implementation manner, a network failure, a failure of another server, and the like may occur, so that another server cannot normally receive the first resolution request forwarded by the server, or send the resolution result of the domain name to the server, and therefore, in order to obtain the resolution result of the domain name sent by another server in time and improve the accuracy of the subsequent response to the first resolution request carrying the domain name, in the present application, if the resolution result of the domain name sent by another server is not received within a second preset time period, the other server does not wait for the resolution result sent by the domain name carried in the first resolution request forwarded last time, and forwards the first resolution request to another server according to a preset time interval until the resolution result of the domain name sent by another server is received, so as to obtain the resolution result of the domain name according to the received resolution result, and updating the target analysis result of the local cache.
If the resolution results of the domain names sent by the other servers are not received within a preset second time period, the method further comprises the following steps:
and if a second analysis request carrying the domain name is received within a preset third time length, directly sending the target analysis result.
In another possible implementation manner, in order to avoid a situation that the first resolution request is frequently forwarded to other servers and the load pressure of other servers is high, after the resolution result of the domain name sent by other servers is not received within the preset second time period, if the server receives the second resolution request carrying the domain name again within a period of time after the preset second time period, the server does not forward the second resolution request to other servers, and directly sends the target resolution result corresponding to the domain name cached locally. Therefore, in the present application, the third duration is preset. After the analysis results of the domain names sent by other servers are not received within the preset second time period, if a second analysis request carrying the domain name is received within the preset third time period, the target analysis result of the local cache is directly sent.
The server receives the domain name resolution results sent by other servers and also receives the valid periods corresponding to the resolution results sent by other servers, updates the locally cached target resolution results according to the received domain name resolution results, and updates the valid periods corresponding to the locally cached target resolution results according to the received valid periods corresponding to the resolution results.
In the present application, when the second time length is set, the second time length may be determined empirically, or may be set to a different value depending on a scene. If it is desired to reduce the time spent waiting for other servers to send the resolution result of the domain name, the preset second duration may be set to be shorter, and if it is desired to reduce the number of times of frequently forwarding the first resolution request to other servers, the preset second duration may be set to be longer.
When the third time length is set, it may be determined empirically, or may be set to different values according to different scenes. If the resolution result of the domain name has strict requirements, the preset third duration may be set to be shorter, and if the number of times of frequently forwarding the second resolution request to other servers is desired to be reduced, the preset third duration may be set to be longer.
Similarly, the time interval may be determined empirically, or may be set to a different value depending on the scene. If it is desired to acquire the resolution result of the domain name sent by the other server as soon as possible, the time interval may be set to be shorter, and if it is desired to reduce the number of times of frequently forwarding the first resolution request to the other server, the time interval may be set to be longer.
In another possible implementation manner, it may occur that a server receives an analysis request for a certain domain name for the first time, the server does not locally cache a target analysis result corresponding to the domain name, and in order to respond to the analysis request sent by the intelligent device, the server needs to forward the analysis request to another server to obtain an analysis result of the domain name carried in the analysis request sent by the other server, send the received analysis result of the domain name, and cache the domain name and the analysis result corresponding to the domain name locally.
The server receives the domain name resolution results sent by other servers and also receives the valid periods corresponding to the resolution results sent by other servers, and the server caches the domain name, the domain name resolution results and the valid periods corresponding to the resolution results locally.
When the validity period is set, the validity periods with different durations can be set according to different scenes. If the accuracy of the resolution result of a certain domain name sent to the intelligent device is strictly guaranteed, the validity period of the domain name can be set to be shorter, so that the server can frequently update the target resolution result corresponding to the certain domain name cached locally; if it is desired to effectively reduce the frequency of the server forwarding the analysis request to other servers, reduce the load of other servers when processing the analysis request, improve the service performance, and process more analysis requests, the validity period of the domain name may be set longer.
Similarly, it is determined that the resolution result of the domain name sent by another server is not received within the preset first time period, and when the server sends the target resolution result, the server also sends a pre-configured time period to the receiving device (including the intelligent device and the lower-level server), that is, the pre-configured time period is sent to the receiving device as the valid period corresponding to the target resolution result, so that the receiving device updates the locally cached resolution result of the domain name and the valid period corresponding to the resolution result according to the target resolution result and the pre-configured time period.
It should be noted that the setting method of the preconfigured time period is the same as the setting method of the validity period, and repeated parts are not described again.
In addition, if it is determined that the target resolution result corresponding to the domain name is locally cached, and the validity period corresponding to the target resolution result is not due, the method further includes:
and sending the target analysis result.
Certainly, after the server determines that the target analysis result corresponding to the domain name is locally cached, the valid period corresponding to the target analysis result is not due, the server directly sends the target analysis result, and does not need to request the analysis result of the domain name carried in the analysis request from other servers, so that the target analysis result locally cached is updated according to the received analysis result.
Fig. 3 is a schematic diagram of a conventional data processing flow, which includes:
s301: and receiving a first resolution request and acquiring the domain name information carried in the first resolution request.
S302: and judging whether a target analysis result corresponding to the domain name is cached locally, if so, executing S303, otherwise, executing S304.
