python服务器代码

以下最小的 websocket 服务器使用Flask-sockets （使用gevent-websocket）。文件名是ws_server.py：

        print(request.headers["Sec-Websocket-Protocol"])
    else:
        print("INFO: No protocol specified")

    if request.headers["Sec-Websocket-Protocol"] == "aProtocol":
        print("INFO: protocol is …
