Problems solved by technology
[0002] Existing stock equipment and equipment that will be launched soon, with the update of technology, most of the communication is based on Http(s) to transmit data, and the data is encrypted and transmitted through a certain known encryption algorithm, but if you encounter The loading of the external network is not completed, which is reflected on the device. At this time, the webpage cannot be loaded and will cause freezes. If the server is used to load and open a separate thread in the webpage, it is easy to cause thread safety problems, because the client is related to the client. Machine and server communication problems, etc.

Embodiment Construction
[0026] The present invention is described below in conjunction with accompanying drawing.
[0027] as attached figure 1 Shown is a non-present device server screenshot method according to the present invention, which includes the following steps,
[0028] The client sends a data request to the server;
[0029] The server starts a new thread to receive the data request sent by the client; the new thread transfer object is a file of the object type;
[0030] Count the number of data requests received by the server, and load the corresponding webpage window for the received data requests; if no data request message is received, initialize a webpage window of the same size, capture the screen and save it as a picture;
[0031] Take a screenshot of the web page window and save it as a picture;
[0032] The saved picture is transmitted to the client through the TCP protocol, and when the saved picture is transmitted to the client through the protocol, encryption processing is per...

The invention discloses a non-existing equipment server screenshot method, which comprises the following steps of: enabling a client to send a data request to a server; starting a new thread by the server, and receiving a data request sent by the client; counting the number of the data requests received by the server, and loading corresponding webpage windows to the received data requests; performing screenshot on the webpage window, and saving the webpage window as a picture; transmitting the stored picture to a client through a protocol; and for common non-existing equipment, when the webpage content needs to be loaded in real time while external network access is forbidden, establishing the corresponding TCP link through the non-existing equipment server screenshot tool, then loading the corresponding webpage through the equipment, and transmitting the screenshot to the non-existing equipment side after loading is completed.
Description
technical field [0001] The invention relates to a non-present device server screenshot method, device and medium, and belongs to the technical field of non-present device servers. Background technique [0002] Existing stock equipment and equipment that will be launched soon, with the update of technology, most of the communication is based on Http(s) to transmit data, and the data is encrypted and transmitted through a certain known encryption algorithm, but if you encounter The loading of the external network is not completed, which is reflected on the device. At this time, the webpage cannot be loaded and will cause freezes. If the server is used to load and open a separate thread in the webpage, it is easy to cause thread safety problems, because the client is related to the client. machine and server communication issues, etc. Contents of the invention [0003] In view of the above-mentioned existing technical problems, the purpose of the present invention is to prop...
