Detailed ways

In order to make the purpose, technical solution, and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and examples. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor shall fall within the protection scope of the present application.

In order to solve the problem of data synchronization between multiple pages through manual operation, the embodiments of the present application further provide a data synchronization method and device, which are applied to a server. The data synchronization method includes the following steps:

Receiving update information sent by a target page, where the update information includes user information of a user who logs in to the target page and an identifier of data to be updated;

Determine the pages to be synchronized from the multiple pages that the user logs in to;

Send the synchronization information to the page to be synchronized, so that the page to be synchronized updates the data corresponding to the data identifier to be updated according to the synchronization information.

The following first introduces a data synchronization method provided by an embodiment of the present application. The data synchronization method may be applied to a server. Specifically, the server may be an HTTP server that provides HTTP protocol and WebSocket protocol communication. The server may also have Other servers with corresponding functions described in the application examples are not limited herein. As shown in FIG. 1, the data synchronization method includes the following steps.

S101. Receive update information sent by a target page.

The target page can be a retrieval page or a function page.

The retrieval page is a data entry page based on a multi-screen page. After the user logs in to the retrieval page, he can enter the required retrieval information on the retrieval page for retrieval. Function pages are pages other than search pages, and each function page has a corresponding function. In one implementation, the function of each function page may be an independent function.

For example, the function page may include a relationship network page, a map analysis page, and a comprehensive research and judgment page. Among them, the relationship network page is used to display the relationship diagram of other people who are related to the retrieved target object. For example, if the user searches for suspect A, the relationship network page will show the relationship between the person and the suspect A: family relationship , Friends, colleagues, etc. The map analysis page is used to display the address information associated with the retrieved target object. The comprehensive research and judgement page is used to display the conclusion after comprehensive judgment according to the relevant information of the retrieved target object.

Both the retrieval page and the function page are connected to the server. In an implementation manner, the connection may be a WebSocket connection. Specifically, the retrieval page and the function page are connected to the server through WebSocket, so that the page and the server can perform two-way communication. The connection method between the server and the retrieval page and the function page may also be other methods, which are not limited herein.

The update information includes user information of a user who logs in to the target page and an identifier of data to be updated. The user information may include at least one of the following: a user name, a user ID, and the like that the user logs in to.

The correspondence between the data and the identifier can be preset, that is, for each data, there can be a corresponding identifier. The identifier of the data to be updated is the identifier corresponding to the data updated by the user on the target page, that is, the user who logged in to the target page has updated the data of the identifier of the data to be updated. The page is updated the same. For example, if the user deletes the data of the suspect A on the relationship network page, and the identifier corresponding to the suspect A is A, the A is the identifier of the data to be updated.

S102. Determine a page to be synchronized from the multiple pages logged in by the user.

The user is a user who logs in to the target page. The user can log in to one page or multiple pages. If the user has logged in to other pages in addition to the target page, the pages to be synchronized can be determined from the other pages.

The server can monitor the page status of each page where the same user logs in. The page status can be divided into a closed state and an open state. Among them, the closed page can be manually closed, or it can be closed abnormally. The closed state of a page means that the connection between the page and the server is broken, and the page cannot be displayed and cannot provide corresponding functions. The open state of the page means that the page is connected to the server, and the page can be displayed to the user and provide corresponding functions. The server determines, from multiple pages logged in by the user, the page whose page status is on as the page to be synchronized.

In an implementation manner, according to different target pages, determining the pages to be synchronized can be divided into the following two cases.

In the first case, if the target page is a retrieval page, the page to be synchronized is determined from the function pages logged in by the user. The user is a user who logs in to the target page, and the function page that the user logs in to is a function page in an open state.

For example, the target page is a retrieval page, and a user who logs in to the retrieval page also logs in a function page, and the function pages that the user logs in include page A, page B, and page C. Wherein, page A and page B are both on and page C is off, the server determines page A and page B as pages to be synchronized.

Among them, all function pages logged in by the user may be determined as pages to be synchronized, and some of the function pages logged in by the user may be determined as pages to be synchronized. It is not limited here.

In the second case, if the target page is a function page, the page to be synchronized may be determined from other function pages logged in by the user except the target page. The user is a user who logs in to the target page, and the function pages other than the target page that the user logs in are function pages in an open state.

For example, the function page that the user logs in includes page A, page B, and page C, where the target page is page A, and page B and page C are both open, the server determines page B and page C as pages to be synchronized.

Among them, all the function pages except the target page that the user logs in to may be determined as pages to be synchronized, and some of the function pages logged in by the user other than the target page may be determined as pages to be synchronized. It is not limited here.

S103. Generate synchronization information for data corresponding to the data identifier to be updated.

The synchronization information is used to indicate that the data corresponding to the data identifier to be updated is updated. Updating data includes operations such as importing, deleting, and selecting data. Depending on the type of operation performed by the user on the target page, the update method indicated by the synchronization information generated by the server will be different.

In an implementation manner, the update information may further include an operation type, where the operation type may include an import operation, a delete operation, a selection operation, and the like. For example, when the operation type included in the update information is an import operation, it means that the user has imported the data corresponding to the data identifier to be updated into the target page.

After the server determines the pages to be synchronized, the server may obtain a target data identifier list corresponding to the page to be synchronized according to a preset correspondence between the pages and the data identifier list. The server can determine whether the data identifier to be updated is stored in the target data identifier list by querying the obtained target data identifier list.

Each page may correspond to a data identification list. The data identification list is used to record the identification of each data included in the corresponding page, that is, the identification recorded in the data identification list is consistent with the data included in the page corresponding to the data identification list. .

Generate synchronization information for the data corresponding to the data identifier to be updated according to the operation type included in the update information and whether the data identifier to be updated is stored in the target data identifier list.

Different types of operations have different roles for the generated synchronization information. Specifically, when the operation type is an import operation, first synchronization information for importing data to be updated into a page to be synchronized may be generated. When the operation type is a delete operation, second synchronization information for deleting data to be deleted from a page to be synchronized may be generated. When the operation type is a selection operation, third synchronization information for selecting data to be selected in a page to be synchronized may be generated.

S104. Send the synchronization information to a page to be synchronized.

After receiving the synchronization information, the page to be synchronized may update the data corresponding to the data identifier to be updated according to the synchronization information.

The data to be synchronized is updated based on the synchronization information, and the generation of the synchronization information is based on the operation type. The following describes the process of generating and sending synchronization information according to different operation types.

In one embodiment, when the operation type is an import operation, it can be considered that the user has performed the data import operation on the target page. For the server, after obtaining the target data identifier list corresponding to the page to be synchronized, it can be determined whether the target data identifier list stores the data identifier to be updated.

If the data identifier to be updated is already stored in the target data identifier list, it means that data corresponding to the data identifier to be updated already exists in the page to be synchronized. At this time, the server may not perform data synchronization on the page to be synchronized corresponding to the target data identifier list. . If the data identifier to be updated is not stored in the target data identifier list, the server may obtain data corresponding to the data identifier to be updated from a preset database and use the data as the data to be updated.

The preset database is used to store various data and the corresponding relationship between the data and the data identifier. Data corresponding to each data identifier can be obtained from the database.

After acquiring the data to be updated, the server may generate first synchronization information including the data to be updated, and send the first synchronization information including the data to be updated to the page to be synchronized. The first synchronization information is used to import the data to be updated into the page to be synchronized.

For a page to be synchronized, after receiving the first synchronization information, data to be updated may be obtained from the first synchronization information, and the data to be updated may be imported into its own page to achieve data synchronization with the target page.

For example, the page to be synchronized is a relational network page. When the operation type is an import operation, the ID of the data to be updated is A, and A is not stored in the target data ID list. Then the server can obtain the data A corresponding to A from the database and generate The first synchronization information of the data A, and the first synchronization information including the data A is sent to the relationship network page. After receiving the first synchronization information containing data A, the relational network page imports the data A into the relational network page.

In one embodiment, when the operation type is a delete operation, it can be considered that the user has performed a data delete operation on the target page. For the server, it can be determined whether the data identifier to be updated is stored in the target data identifier list.

If the data identifier to be updated is not stored in the target data identifier list, it means that there is no data corresponding to the data identifier to be updated in the page to be synchronized. At this time, the server may not perform data synchronization on the page to be synchronized corresponding to the target data identifier list. If it is stored, the server generates second synchronization information for the data to be deleted, and sends the second synchronization information to the page to be synchronized. The data to be deleted is data corresponding to the data identifier to be updated, and the second synchronization information is used to delete the data to be deleted from the page to be synchronized.

For a page to be synchronized, after receiving the second synchronization information, the to-be-deleted data in the own page can be deleted according to the second synchronization information to achieve data synchronization with the target page.

In one embodiment, when the operation type is a selection operation, it can be considered that the user has performed a data selection operation on the target page. For the server, it can be determined whether the data identifier to be updated is stored in the target data identifier list.

If the to-be-updated data identifier is stored in the target data identifier list, it indicates that data corresponding to the to-be-updated data identifier exists in the page to be synchronized. At this time, third synchronization information for the data to be selected can be generated, and the third synchronization information Sent to the page to be synchronized. The data to be selected is data corresponding to the data identifier to be updated, and the third synchronization information is used to select the data to be selected in the page to be synchronized. At this time, for the page to be synchronized, after receiving the third synchronization information, the data to be selected in the own page can be selected according to the third synchronization information to achieve data synchronization with the target page.

If no data identifier to be updated is stored in the target data identifier list, it means that there is no data corresponding to the data identifier to be updated in the page to be synchronized. At this time, the server may first obtain the data corresponding to the data identifier to be updated, and the data is to be selected. data. The data to be selected may be obtained from a database preset by the server, or may be obtained by other methods, which is not limited herein. After acquiring the data to be selected, the server may generate third synchronization information including the data to be synchronized, and may send the third synchronization information including the data to be synchronized to the page to be synchronized.

For a page to be synchronized, after receiving the third synchronization information containing the data to be synchronized, the data to be synchronized can be obtained from the third synchronization information, the data to be selected is imported into its own page, and the Select data to synchronize data with the target page.

In order to know the status of each function page in real time, the server can monitor each function page. In one embodiment, the pages that the user has logged in may include a function page and a retrieval page. Among them, the function pages are connected to the server and can communicate with the server in both directions. For each function page, a heartbeat packet can be set to be sent to the server at a preset time interval, and the heartbeat packet can include status information of the function page itself. The preset time interval may be customized. For example, it may be set to send a heartbeat packet to the server every half a second. The page status of the function page for sending heartbeat packets is open.

For the server, it can receive the heartbeat packet sent by the function page, which is any function page connected to the server. The server can receive the heartbeat packet sent by the function page at a preset interval. According to the received heartbeat packet, the page status of the function page may be determined, which may include at least the following two implementation manners.

In the first implementation manner, if the next heartbeat packet is received within a preset time period, it can be determined that the page state of the function page is an open state.

The preset duration may be set by user. The preset duration starts from the time when the heartbeat packet is received, and the implementation of the preset duration may be controlled by a timer. In one implementation, when the server receives the heartbeat packet sent by the function page, the timer starts to count. When the next heartbeat packet sent by the function page is received within a preset period of time, the page status of the function page can be determined as On.

If the next heartbeat packet is not received within a preset time period, the connection to the function page can be interrupted, and the page status of the function page is determined to be closed. When the connection between the server and the function page is a WebSocket connection, the server may interrupt the connection by deleting the WebSocket connection with the function page.

In the second implementation manner, the heartbeat packet may include user information, and a user corresponding to the user information is a user who logs in to the function page.

After the server receives the heartbeat packet sent from the function page, it can obtain user information from the heartbeat packet. According to the user information, the server establishes a connection with the function page. Among them, the established connection corresponds to user information.

After the server establishes a connection with the function page, the page status of the function page is determined to be open, which can include the following two situations: If the function page sends a heartbeat packet for the first time, and the current page status of the function page is closed, then The page state of the function page is determined to be an open state; if the current page state of the function page is already an open state, the page state of the function page is maintained unchanged and remains open.
