Description

Data updating method and device
Technical Field
The present application relates to the field of computer technologies, and in particular, to a method and an apparatus for updating data.
Background
Currently, in practical applications, there are some category data with a small update frequency and an unfixed update time, such as news category data in a certain news Application (APP). It is assumed that category data in the news APP includes category data of entertainment type, military type, social type, and the like. If the staff of the news APP finds that the click rate of the user on the entertainment type news is small after performing data statistics on the click rate of the recent user on various types of news, the staff can modify the category information of the news content in the server and directly delete the entertainment type news data.
In order to ensure that after modifying the category data in the server, the category data displayed in the news APP is consistent with the updated category data in the server, in the prior art, the following two methods are generally adopted to make the category data displayed in the news APP consistent with the updated category data in the server:
the method comprises the following steps: after the server establishes long connection with the news APP, if the server updates the category data, the server sends the updated data to the news APP. When the news APP receives the data, the data is stored locally. When the user opens the user operation interface displaying the category data, the user operation interface displays the updated data. However, this method has certain disadvantages: the news APP may not be able to display category data normally.
This is because in practical applications, different versions of APPs are usually developed for different platforms or operating systems, and even for the same platform and the same operating system. Since different versions of APP may only support data in one or several formats, the server stores data in different formats for categories. After the long connection is established between the news APP and the server, if the server cannot acquire the version information of the news APP, the server will randomly send the category data in a certain format to the news APP, which may cause the news APP to be incapable of analyzing the category data in the certain format, so that the news APP cannot normally display the category data.
The second method comprises the following steps: as long as the user opens the operation interface for displaying the category data in the news APP, the news APP actively sends a data updating request to the server, and the server sends the latest data to the client according to the data updating request. The data updating request comprises the version information of the news APP, so that the news APP can send the category data matched with the version of the news APP according to the version information of the news APP contained in the data updating request.
However, the second method has other disadvantages: the waste of network resources.
This is because, when the server does not update the data, the news APP still sends a data update request to the server, and finally the category data displayed by the news APP does not change. This results in a waste of network resources.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the 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.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
In order to solve the problem of waste of network resources in a method for updating category data in the prior art, an embodiment of the present application provides a method for updating data.
The specific flow diagram of the method is shown in fig. 1a, and comprises the following steps:
and step 11, after the category data is updated, the server sends a data updating instruction to the client.
The data updating method provided by the embodiment of the application can be used for updating the category data. The category data may be category data with a low update frequency and a non-fixed update time. Data with a low update frequency and a non-fixed update time may include, but is not limited to, billing category data in a payment platform or news category data in a news APP, etc. Of course, other types of category data may be updated, such as category data with a faster update frequency or a fixed update time.
The billing category data in the payment platform may include, but is not limited to, shopping type, catering type, water and electricity type, or telephone rate type, for example. As shown in fig. 1b, the data shown in fig. 1b is the bill category data in a certain payment platform, and if the user wishes to view the recent consumption record about the catering aspect, the user can click on "catering" in the page, so as to view the relevant consumption record.
Since the category data shown in fig. 1b is provided by the server, the category data in the client is consistent with the category data in the server. After the data in the server is updated, in order to keep the category data in the client consistent with the category data in the server, the server may send a data update instruction to the client to notify the client that the category data in the server has been updated, so that the client completes subsequent operations according to the instruction, and finally obtains the updated category data.
It should be noted that, only when the connection is established between the server and the client, the server can send a data update instruction to the client; if the connection between the server and the client is not established, the server cannot send a data updating instruction to the client. The connection established between the server and the client may be a long connection or a short connection, which is not limited in this embodiment of the present application. Specifically, the server may send the data update instruction to the client immediately when monitoring that the client is started and establishes a connection with the server, or may send the data update instruction to the client when monitoring that the client is started and opens an interface for displaying the category data (when the client opens the interface for displaying the category data, the client may send a preset message to the server so that the server knows that the client has opened the interface for displaying the category data).
And step 12, the server receives a data updating request returned by the client according to the data updating instruction.
After receiving the data update command, the client sends a data update request to the server, so that the server receives the data update request and continues to execute step 13.
Specifically, the client may send the data update request to the server immediately after receiving the data update instruction, or may not send the data update request after receiving the data update instruction, but send the data update request to the server when determining that a certain condition is satisfied. For example, after receiving the data update instruction, the client may send a request to the server when opening an interface for displaying category data, or may send a data update request to the server when determining that the user clicks a certain control in the client after receiving the data update instruction.
Along the above example, as shown in fig. 1c, after the client receives the data update instruction, a prompt inquiring whether to update data may be displayed on the operation interface of the client, and if the user clicks the determination control, the client sends a data update request to the server; and if the user clicks the rejection control, the data updating request is not sent to the server for the moment.
And step 13, the server sends the updated category data to the client according to the data updating request.
In the embodiment of the application, the data update request sent by the client to the server may include version information of the client. Therefore, after receiving the data updating request, the server can send the updated category data matched with the version information to the client according to the version information.
And after the client receives the updated category data sent by the server, the updated category data can be adopted to update the category data locally stored by the client.
In the method, the server sends the data updating instruction to the client only after the category data is updated, the client returns the data updating request according to the received data updating instruction, the server sends the category data to the client after receiving the data updating request, and the network resources consumed by the server for sending the data updating instruction to the client are generally far less than the network resources consumed by the server for sending the category data to the client.
In step 11 shown in fig. 1a, after one update, the server may send a data update command to the client whenever the server and the client are changed from the unconnected state to the connected state before the next update. According to the method shown in fig. 1a, when the client receives the data update instruction, the client returns a data update request, and the server sends updated data to the client according to the data update request, which may cause a problem of unnecessary resource waste because the client needs to repeatedly update data when establishing connection with the server again after having updated the data.
In order to avoid the problem of resource waste, after the category data is updated, the server may send a data update instruction corresponding to the updated category data to the client, where if the updated category data is different, the corresponding data update instructions are also different. Specifically, the data update instruction corresponding to the updated category data may carry a version number corresponding to the updated category data, or an MD5 value corresponding to the updated category data, or the like, as long as it is ensured that the updated category data only corresponds to one globally unique data update instruction.
Correspondingly, when receiving a data updating instruction sent by the server, the client firstly determines whether the data updating instruction exists in a log recorded in the local by the client, and if so, the client does not send a data updating request to the server; if the data does not exist, the data updating instruction is recorded in a local log, and a data updating request is sent to the server, so that the server returns the updated data.
For example, assuming that a data update instruction recorded in a local log by a client is a data update instruction carrying version numbers v1 and v2, at this time, data in a server is updated, and the updated data version number is v3, after the data is updated, the server sends a data update instruction carrying version number v3 to the client, and after the client receives the data update instruction, it is determined that the data update instruction carrying version number v3 does not exist in the local log, the data update instruction carrying version number v3 is recorded in the local log, and a data update request is sent to the server, so that the server returns the updated data. If the client is closed and started again in the following, and connection is established with the server, the server will send the data update instruction carrying the version number v3 to the client again, and at this time, after receiving the data update instruction carrying the version number v3, the client will determine that the data update instruction carrying the version number v3 already exists in the local log, and therefore, no data update request is sent to the server, so that unnecessary data update is avoided, and unnecessary resource waste is also avoided.
In addition, in practical application, a situation that the client cannot receive a data update instruction sent by the server may occur due to a network failure or the like, and if the client is the client that is just installed by the user at this time, the category data locally stored by the client only has preset default category data, or even does not store any category data, the client cannot normally display the updated category data. Therefore, in the embodiment of the application, except that the client sends the data update request to the server after receiving the data update instruction sent by the server, if the client does not receive the data update instruction sent by the server, but the client does not locally store the category data, or the category data locally stored by the client is preset default category data, the client may also send the data update request to the server, so that the server returns the updated category data to the client according to the data update request.
Based on the same idea, the present application further provides a device for updating data.
