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 invention.
in order to solve the problem of realizing data synchronization among multiple pages in a manual operation mode, the embodiment of the invention provides a data synchronization method and a data synchronization device, which are applied to a server, wherein the data synchronization method comprises the following steps:
Receiving update information sent by a target page, wherein the update information comprises user information of a user logging in the target page and a data identifier to be updated;
Determining a page to be synchronized from a plurality of pages logged in by a user;
generating synchronous information aiming at data corresponding to the data identification to be updated;
And sending 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.
in the technical scheme provided by the embodiment of the invention, a server receives update information sent by a target page, and determines a page to be synchronized from a plurality of pages logged by a user; and generating synchronous information aiming at the data corresponding to the data identifier to be updated, sending the synchronous information to the page to be synchronized, and updating the data corresponding to the data identifier to be updated by the page to be synchronized according to the synchronous information. Therefore, the server determines the page to be synchronized, and the page to be synchronized is updated according to the synchronization information of the server, so that data synchronization among multiple pages is realized, the problem of updating by manual operation is solved, and the efficiency of data synchronization is improved.
First, a data synchronization method provided by an embodiment of the present invention is described below, as shown in fig. 1, the data synchronization method is applied to a server, and specifically, the server may be an HTTP server that provides communication between an HTTP protocol and a WebSocket protocol. The data synchronization method includes the following steps.
S101, receiving the updating information sent by the target page.
the target page may be a search page or a function page.
The retrieval page is a data entry page in the multi-screen-based page, and after a user logs in the retrieval page, required retrieval information can be input in the retrieval page for retrieval. The function pages are pages other than the retrieval page, and each function page has an independent function.
For example, the function page may include: a relationship network page, a map analysis page, a comprehensive study page and the like. The relationship network page is used to display a relationship diagram of other people associated with the retrieved target object, for example, if the user retrieves suspect a, the relationship network page will display the relation of people associated with the suspect a: family relationships, friend relationships, co-worker relationships, and the like. The map analysis page is used to present address information associated with the retrieved target object. And the comprehensive study and judgment page is used for displaying a conclusion after comprehensive judgment is carried out according to the relevant information of the retrieved target object.
The retrieval page and the function page are connected with the server, the connection can be Websocket connection, specifically, the retrieval page and the function page are connected with the server through the Websocket, and therefore bidirectional communication can be conducted between the pages and the server.
the updating information comprises user information of a user logging in the target page and a data identifier to be updated. The user information may include at least one of: user name, user identification, etc. of user login.
The corresponding relationship between the data and the identifier may be preset, that is, for each data, an identifier is corresponding to each data. The data to be updated is identified as: and the user carries out the identification corresponding to the updated data on the target page. That is, the user logging in the target page updates the data identified by the data to be updated, and the data identified by the data to be updated needs to be updated in the same way on other function pages logged in by the user. For example, the user deletes the data of the suspect a on the relationship network page, and if the identifier corresponding to the suspect a is a, the identifier a is the identifier of the data to be updated.
S102, determining a page to be synchronized from a plurality of pages logged in by a user.
the server can monitor the page states of all pages logged in by the same user, wherein the page states can be divided into a closing state and an opening state. The page in the closed state can be manually closed or abnormally terminated; the closing state of the page means that the connection between the page and the server is disconnected, and the page cannot be displayed or provide corresponding functions; the open state of the page means that the page is connected with the server, and the page is displayed for the user and provides corresponding functions. And the server determines the page with the page state being the open state as the page to be synchronized from a plurality of pages logged by the user.
In one embodiment, according to the difference of the target pages, determining that the pages to be synchronized can be divided into the following two cases:
in the first case, if the target page is a search page, a page to be synchronized is determined from the function pages logged in by the user. And the function page logged in by the user is the function page in the open state.
for example, the target page is a search page, and the function pages for logging in by the user include page a, page B, and page C. And if the page A and the page B are both in an open state and the page C is in a closed state, the server determines the page A and the page B as pages to be synchronized.
in the second case, if the target page is a functional page, determining a page to be synchronized from other functional pages, except the target page, which are logged in by the user. And the other function pages, except the target page, logged in by the user are the function pages in the open state.
For example, the functional page where the user logs in includes a page a, a page B, and a page C, where the target page is the page a, and both the page B and the page C are in an open state, and then the server determines the page B and the page C as pages to be synchronized.
S103, generating synchronous information of data corresponding to the data identification to be updated.
the synchronization information is used for indicating that the data corresponding to the data identifier to be updated is updated. According to different operation types of the user operating on the target page, the updating modes indicated by the synchronous information generated by the server are different.
In one embodiment, the update information may further include an operation type, wherein the operation type may include an import operation, a delete operation, a select operation, and the like. For example, when the operation type included in the update information is an import operation, it indicates that the user has imported the data corresponding to the data identifier to be updated into the target page.
After determining the page to be synchronized, the server may obtain the target data identifier list corresponding to the page to be synchronized according to a preset correspondence between the page and the data identifier list. The server can determine whether the target data identifier list stores the data identifier to be updated by querying the acquired target data identifier list.
each page corresponds to a data identifier list, and the data identifier list is used for recording identifiers of data included in the corresponding page, that is, the identifiers recorded in the data identifier list are consistent with the data included in the page corresponding to the data identifier list.
and generating synchronous information aiming at the data corresponding to the data identifier to be updated according to the operation type included in the updating information and whether the data identifier to be updated is stored in the target data identifier list.
the generated synchronization information differs according to the type of operation. Specifically, when the operation type is an import operation, first synchronization information for importing the data to be updated into the page to be synchronized is generated; when the operation type is deleting operation, second synchronous information for deleting the data to be deleted from the page to be synchronized is generated; and when the operation type is selection operation, generating third synchronization information for selecting the data to be selected in the page to be synchronized.
And S104, sending the synchronization information to the page to be synchronized.
after the page to be synchronized receives the synchronization information, the data corresponding to the data identifier to be updated can be updated according to the synchronization information.
And updating data of the page to be synchronized according to the synchronization information, and generating the synchronization information according to the operation type. The generation and transmission of the synchronization information will be described below according to different operation types.
in one embodiment, when the operation type is an import operation, it indicates that the user performs an import operation of data on the target page. For the server, after a target data identifier list corresponding to a page to be synchronized is obtained, whether a data identifier to be updated is stored in the target data identifier list is judged.
if the target data identification list stores the data identification to be updated, the server does not perform data synchronization on the page to be synchronized corresponding to the target data identification list; if the target data identifier list does not store the identifier of the data to be updated, the server may obtain the data corresponding to the identifier of the data to be updated from a preset database, and use the data as the data to be updated.
the preset database is used for storing various data and the corresponding relation between the data and the data identification. Data corresponding to the data identification can be obtained in 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 for importing the data to be updated into the page to be synchronized.
At this time, for the page to be synchronized, after receiving the first synchronization information, the data to be updated is obtained from the first synchronization information, and the data to be updated is imported into the page of the page to be synchronized 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 data identifier to be updated is a, and a is not stored in the target data identifier list, the server may obtain the data a corresponding to a from the database, generate first synchronization information including the data a, and send the first synchronization information including the data a to the relational network page. And after receiving the first synchronization information containing the data A, the relation network page imports the data A into the relation network page.
In one embodiment, when the operation type is a delete operation, it indicates that the user performed a delete operation on the target page. For the server, whether the target data identifier list stores the data identifier to be updated is judged.
if not, the server does not perform data synchronization on the page to be synchronized corresponding to the target data identification list; and if the data is stored, the server generates second synchronization information aiming at 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 for deleting the data to be deleted from the page to be synchronized.
At this time, for the page to be synchronized, after receiving the second synchronization information, deleting the data to be deleted in the page of the page to be synchronized according to the second synchronization information, so as to achieve synchronization with the target page.
In one embodiment, when the operation type is a selection operation, it indicates that the user performs a data selection operation on the target page. For the server, whether the target data identifier list stores the data identifier to be updated is judged.
And if the data to be selected is stored, generating third synchronous information aiming at the data to be selected, and sending the third synchronous information 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 for selecting the data to be selected in the page to be synchronized. At this time, for the page to be synchronized, after the third synchronization information is received, the data to be selected in the page is selected according to the third synchronization information, so as to achieve synchronization with the target page.
If the data is not stored, the server firstly acquires the data corresponding to the data identifier to be updated, and the data is the data to be selected. The data to be selected can be acquired from a database preset by the server. After the server acquires the data to be selected, third synchronization information containing the data to be synchronized is generated, and the third synchronization information containing the data to be synchronized is sent to the page to be synchronized.
at this time, for the page to be synchronized, after third synchronization information containing the data to be synchronized is received, the data to be synchronized is acquired from the third synchronization information, the data to be selected is imported into the page of the page to be synchronized, and the data to be selected in the page of the page to be synchronized is selected, so that the page to be synchronized with the target page is realized.
in order to know the state 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 include a function page and a retrieval page. The function pages are all connected with the server and can carry out two-way communication. For each function page, sending a heartbeat packet to the server according to a preset time interval can be set, wherein the heartbeat packet comprises the state information of the function page. The preset time interval may be set by a user, for example, it may be set to send a heartbeat packet to the server every half second. And the page state of the functional page for sending the heartbeat packet is an open state.
For the server, the heartbeat packet sent by the function page can be received, and the function page is any function page connected with the server. The server can receive the heartbeat packet sent by the function page at preset time intervals. According to the received heartbeat packet, the page state of the function page can be determined, wherein at least the following two implementation manners can be included:
In a first implementation manner, if a next heartbeat packet is received within a preset time period, the page state of the function page is determined to be an open state.
the preset time length is set by a user, and the realization of the preset time length can be controlled by a timer. When the server receives the heartbeat packet sent by the functional page, the timer starts to time, and when the server receives the next heartbeat packet sent by the functional page within the preset time length, the page state of the functional page can be determined to be the open state.
And if the next heartbeat packet is not received within the preset time length, interrupting the connection with the function page and determining that the page state of the function page is in a closed state. When the connection between the server and the function page is the WebSocket connection, the server may interrupt the connection in a manner that the server deletes the WebSocket connection with the function page.
in a second implementation manner, the heartbeat packet may include user information, and a user corresponding to the user information is a user of the login function page.
after the server receives the heartbeat packet sent by the function page, the user information can be obtained from the heartbeat packet. And establishing connection between the server and the function page according to the user information. Wherein the established connection corresponds to the user information.
After the server establishes a connection with the function page, determining that the page state of the function page is an open state, which may include the following two cases: if the functional page sends a heartbeat packet for the first time and the current page state of the functional page is a closed state, determining the page state of the functional page as an open state; if the current page state of the functional page is already in the open state, the page state of the functional page is kept unchanged and is still in the open state.
In the technical scheme provided by the embodiment of the invention, a server receives update information sent by a target page, and determines a page to be synchronized from a plurality of pages logged by a user; and generating synchronous information aiming at the data corresponding to the data identifier to be updated, sending the synchronous information to the page to be synchronized, and updating the data corresponding to the data identifier to be updated by the page to be synchronized according to the synchronous information.
