when the 2G equipment is not in a chat interface, the 2G equipment and the server are not in a socket long connection state, at the moment, the chat message sent by the APP is stored to the server, and the chat message is set as an unread offline message;
the 2G equipment can inquire whether unread offline messages exist or not through a second http short connection processing module at regular time;
if the unread offline messages exist, when the 2G equipment user enters the chat interface and establishes socket long connection with the server through the second socket long connection processing module, the second socket long connection processing module extracts the latest unread offline messages from the server, and the server sets the extracted unread offline messages as read.
Further, the APP receives a message module from the 2G device, specifically: when the APP is online, the APP and the server establish socket long connection through a first socket long connection processing module, the 2G equipment sends chat messages to the server, and the server pushes the chat messages to the APP;
when the APP is offline, the APP and the server are not in a socket long connection state, the chat messages are stored in the server, and the chat messages are set to be unread offline messages.
Further, when the APP logs in again or goes online from offline, the APP requests all the previously unread offline message lists through the first HTTP short connection processing module, and the server sets the taken unread offline messages as read.
