Implements RFC6455. "Establish a WebSocket connection" consists of three algorithms: setting up a connection, creating and transmiting a handshake request, and validating the handshake response. parse ( 3、Websocket握手连接 握手部分主要是根据Websocket握手包进行解析，然后根据Sec-WebSocket-Key进行SHA1哈希，生成相应的key,返回给客户端，与客户端进行握手。 代码如下： As the name suggests, the API uses WebSocket protocol to establish a single long standing TCP connection after an HTTP handshake to receive streaming quotes. In this application, the client sends a "ping" message to the server every second, and the server responds with a "pong" message. Is there any way to easily make a HTTP request with C++? Specifically, I want to download the contents of a page (an API) and check the contents to see if it contains a 1 or a 0. The client listens for "pong" messages and logs them, keeping track of how many message exchanges there have been. For WebSocket and gRPC connections, this is the total number of bytes sent from the server to the client through the connection. c http-websocket. 0 the WSServer has been completely rewritten with many new features, better support, better extendability and generally as a more stable WebSocket server.
