Embodiment 1
[0057] figure 1 It is a flow chart of a method for tracking attendance provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of tracking attendance for an attendance user carrying an attendance user terminal. The method can be executed by an attendance tracking device. The device can be realized by software and / or hardware, and generally can be integrated in the attendance user terminal. The method specifically includes the following steps:
[0058] Step 110, establishing a persistent WebSocket connection with the server.
[0059] Among them, the WebSocket protocol is a new network protocol based on TCP (Transmission Control Protocol, Transmission Control Protocol), which realizes full-duplex communication between the browser and the server, and allows the server to actively send information to the client. Based on HTTP (HyperText Transfer Protocol, hypertext transfer protocol) connection, the server passively receives the client's...
Embodiment 2
[0085] figure 2 It is a flowchart of a method for attendance tracking provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. Specifically, the location acquisition request sent by the receiving server through the WebSocket long connection Before, it further includes: receiving the reconnection acquisition request sent by the server through the WebSocket long connection; according to the reconnection acquisition request, determining whether the attendance user terminal is connected to the attendance attendance user terminal within the preset time from the current moment The WIFI devices in the area are reconnected, and the determination result is sent to the server through the WebSocket persistent connection. The method specifically includes the following steps:
[0086] Step 210, establishing a persistent WebSocket connection with the server.
[0087] Step 220: Receive the connection status acquisition request ...
