在上述代码中,我们使用select.select方法监视socket的可写状态。如果socket可写,则表示连接已建立;否则,表示连接未建立。 状态图 下面是一个状态图,描述了socket连接的状态转换: connect()connection successconnection failedsend datawait for responsereceive dataconnection closedConnectingConnectedSendingReceiving 在上述状...
这个方法是用来处理错误异常的,如果一旦socket的程序出现了通信的问题,就可以被这个方法捕捉到。 on_open方法: AI检测代码解析 def on_open(ws): def run(*args): for i in range(30): # send the message, then wait # so thread doesn't exit and socket ...

Now we are able to open a socket listen for connections and respond, we can add HTTP as the communication protocol and then have a webserver. To start with lets simply echo back the important parts of a HTTP message, i.e. the verb, request target, and any headers. ...
