websocket?

Websocket is no ordinary Internet connection? What I want is the kind of the HTTP protocol

CodePudding user response:

The Http protocol is one-way, cannot push messages, there are several ways before the websocket appeared, but trouble, websocket is the most convenient,
Websocket is just an agreement from the server, of course, to chat, also need to develop server-side code, can try this, chat web end websocket example,

HTTP if can use the Transfer - Encoding: chunked, as long as the logo data without end can maintain a long connection, have data to send, as is the case, have seen before, now mostly use the ws,
