Preferred embodiment of the invention

The main implementation principles, specific implementation manners, and the corresponding beneficial effects that can be achieved by the technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a method for acquiring page data according to an embodiment of the present invention, and the specific processing procedure thereof is as follows:

Step 11: The web server receives the data acquisition request message sent by the web browser, and when the page data of the page accessed by the web browser is updated, the web browser needs to obtain the real-time page data of the page, and the page stored in the service processor The data is stored in association with the data source identification information. Therefore, the web browser needs to obtain the corresponding page data through the data source identification information corresponding to the page data of the page. Therefore, in the embodiment of the present invention, the web server receives the data obtained by the web browser. The request message can be, but is not limited to, the following two implementations:

The first implementation situation: When updating the page data of the page accessed by a specified web browser, the web server receives a data acquisition request message sent by the specified web browser in step 11, where only the data acquisition request message is needed. The data source identification information corresponding to the page data to be updated may be included. Since each web browser can access at least one page at the same time, and the page data of each page corresponds to one data source respectively, the data acquisition request message may be Containing at least one data source identification information;

The second implementation situation: when updating the page data of the page accessed by the at least two web browsers, the web server receives the data sent by at least two web browsers in step 11 The request message, each data acquisition request message includes browser identifier information corresponding to the web browser that sends the data acquisition request message, and data source identification information corresponding to the page data to be updated by the web browser, where each data The acquisition request message includes a browser identification information and at least one data source identification information.

Step 12: The web server obtains corresponding page data from the service processor according to each received data acquisition request message.

In the embodiment of the present invention, the web server may be, but is not limited to, each data source identification information in each data acquisition request message, and obtain corresponding page data from the service processor according to the data source identification information, where The page data of the pages may be stored in different service processors respectively. Therefore, after receiving the data acquisition request message, the web server separately identifies each data source identification information in each of the received page update request messages according to the Data source identification information, in all the service processors, determining a service processor storing the page data corresponding to the data source identification information, and then transmitting the data source identification information to the determined service processor, the service processor After receiving the data source identification information, the page data corresponding to the data source identification information is searched for in the page data stored by the data source, and then the found page data is sent to the web server, where the data acquisition request message includes at least two data. When the source identifies the information, it identifies each data source The service processor may also send the data source identification information and the found page data to the web server.

For the second implementation described above, since at least two web browsers send a data acquisition request message to the web server, the web server needs to determine which web browser the page data sent by the service processor is for, so that the subsequent web server Sending the page data to the corresponding web browser, so for each data source identification information in each data acquisition request message, the web server further sends the browser identification information carried in the data acquisition request message to the corresponding service. After processing the page data, the service processor sends the browser identification information, the data source identification information, and the found page data to the web server.

In addition, the data acquisition request message received by the web server may also carry the time interval information. At this time, the web server sends the time interval information to the corresponding service processor, and the service processor may subsequently perform the corresponding information according to the time interval information. The time interval sends page data to the web server, and the web server can send heartbeat information to the service processor at each time interval. When the service processor does not receive the heartbeat information of the web server for N consecutive time intervals, the service processor stops sending page data to the web server, where the value of N can be preset, then when the web server fails, the service The processor does not always send page data to the web server, which effectively saves transmission resources.

Step 13: The web server stores the obtained page data in its own volatile storage space. For the first implementation, the web server stores the data source identification information and the page data obtained from the service processor in its own volatile storage space for each data source identification information received;

For the second implementation scenario, the web server obtains, for each data source identifier information in each of the received data request messages, the browser identifier information carried in the data acquisition request message, the data source identifier information, and the obtained information. The page data to be stored is correspondingly stored in its own volatile storage space.

In the embodiment of the present invention, storing the page data in the volatile storage space is equivalent to buffering the page data, so that the web server can subsequently send the corresponding page data to the web browser.

If the web browser stops updating the page data, the web browser sends a data acquisition stop message to the web server, and the web server sends a data acquisition stop message to the corresponding service processor, and after receiving the message, the service processor no longer sends the message. The web server sends the page data, and the web server can further delete the cached page data corresponding to the web browser.

In addition, if the web server does not receive the page data sent by the service processor within a preset time period, it is confirmed that the service processor has failed, and the web server sends a fault message to the web browser.

In the embodiment of the present invention, the browser identifier information may be sent by the web browser to the web server in the data acquisition request message, or may be assigned to each web browser by the web server after receiving the data acquisition request message. The information is then sent to the appropriate web browser.

As shown in FIG. 2, it is a flowchart of a page update method in an embodiment of the present invention, and the specific processing process thereof is as follows: Step 21: The web server receives a page update request message periodically sent by the web browser. If the page data of the page accessed by the at least two web browsers is updated, the page update request message received by the web server includes sending the message. Browser identifier information corresponding to the web browser.

In the embodiment of the present invention, the web browser may, but is not limited to, periodically calling a direct webpage remote call (DWR, Direct Web Remotinig) through a javascript script to periodically send a page update request message to the web server, since the javascript script does not need to be in the java environment. Execution, so the web browser does not need to download the client such as Applet, which effectively improves the processing efficiency of the page update.

Step 22: The web server sends the page data stored in its own volatile storage space to the web browser.

If only the page data of the page accessed by the specified web browser is updated, the web server sends the corresponding relationship between the data source identification information and the page data stored in the own volatile storage space to the web browser;

If the page data of the page accessed by the at least two web browsers is updated, the web server searches for the browser identification information in its own volatile storage space according to the browser identification information for each browser identification information. Corresponding relationship between the data source identification information and the page data, and the corresponding relationship between the found data source identification information and the page data is sent to the web browser corresponding to the browser identification information.

Step 23: The web browser updates the page data to be updated according to the received page data.

The web browser updates the page data to be updated according to the correspondence between the received data source identification information and the page data.

In addition, the web browser can also determine whether the obtained page data is empty, specifically: the web browser determines whether the obtained page data is empty, and if not, updates according to the page data, if If it is empty, it is further determined whether the number of times the obtained page data is empty exceeds a preset threshold. If it is exceeded, the page update request message is stopped from being sent to the web server, and if not, the page update request message is continuously sent. In the embodiment of the present invention, the web server may, but is not limited to, delete the page data that has been sent to the web browser.

According to the foregoing process, in the technical solution of the embodiment of the present invention, the web server first receives the data acquisition request message sent by the web browser, and then the web server obtains the corresponding page from the service processor according to each data acquisition request message. Data, and the obtained page data is stored in its own volatile storage space, so that the web server needs to update the page data in the volatile storage space; the web server receives the page update sent by the web browser at regular intervals. After requesting the message, according to each page update request message, respectively searching for corresponding page data in its own volatile storage space, and sending the found page data to the web browser that sends the page update request message, the web browser The page data to be updated may be updated according to the received page data, so that the web server can separately send the page data stored in the volatile storage space to the corresponding web browsing when the web browser requests the page update.
