The cross-screen display method comprises the following processing flows:
firstly, when the server is deployed, the layout of the pages to be displayed is determined through the configuration file with the configuration information (for example, the layout mode of the pages to be displayed is 2 x 3, which means that the pages to be displayed are arranged in a 2-row 3-column matrix manner), and the resolution of the pages to be displayed. After the service is started, the display client allocates a parameter ClientID to each page to be displayed according to the configuration information, wherein the parameter ClientID is the display device identifier.
And secondly, opening a page of the application program control client and adding a cross-screen mode. Multiple modes can be newly established for displaying pages to be displayed of multiple projects, and each mode is added with webpage address information of a single page to be displayed, the distance from the pixel point of the starting position of the whole physical large screen to the left, the distance from the pixel point to the left, the height, the width and the scaling ratio, or the scaling ratio of the page to be displayed corresponding to the physical large screen is added based on the layout of the display equipment.
In the process of displaying the page to be displayed on the display equipment, each display equipment is provided with an electronic agent client, each electronic agent client configures an address on the server, and after the electronic agent client is opened, the electronic agent client automatically establishes a websocket communication protocol connection with the server. After the server side sends the configuration information to the client side, the display device displays the page to be displayed according to the configuration information.
And providing operation buttons such as ' all on ', ' all off ', ' forced refresh ', buffer clearing ' and the like on an application program control client interface of the client, so that an application program programming interface of the server can be called through the interface, and the server sends messages to each electronic agent client after receiving the operation instructions, thereby controlling the display of each electronic agent client.
For all opening operation, after the client sends an operation instruction of 'all opening' to the server, the server opens the page to be displayed corresponding to the display device identifier through each electronic agent client (namely, desktop client). One electronic agent client can open pages to be displayed corresponding to a plurality of webpage addresses, and only need to piece together the contents of the configured pages to be displayed according to configuration information to form a desktop corresponding to the display equipment.
For all closing operation, after the client sends an operation instruction of 'all closing' to the server, the server closes the page to be displayed corresponding to the display equipment identifier through each electronic agent client. One electronic agent client can close the pages to be displayed corresponding to the multiple web page addresses.
For the forced refreshing operation, after the client sends an operation instruction of forced refreshing to the server, the electronic proxy client does not acquire the configuration information with the display page from the cache resource, but requests the configuration information of the page to be displayed from the server again, so as to ensure the real-time performance of updating the page to be displayed in the electronic proxy client.
For the cache clearing operation, after the client sends an operation instruction of 'clearing cache' to the server, the client clears the cache of the webpage displayed on the electronic proxy client through a software development tool, so that sufficient program running space can be ensured, and when the server updates resources, the client has sufficient space to load the resources updated by the server based on the cache strategy of a local browser.
