Python 使用 websocket-client

import websocket

def on_message(ws, message):
    print(message)

def on_error(ws, error):
    print(error)

def on_close(ws):
    print("WebSocket连接已关闭")

def on_open(ws):
    print("WebSocket连接已打开")
    # 在连接建立后可以发送消息
    ws.send("Hello, WebSocket!")

if __name__ == "__main__":
    websocket.enableTrace(True) # 开启调试信息
    ws = websocket.WebSocketApp("ws://echo.websocket.org/",
                                on_message=on_message,
                                on_error=on_error,
                                on_close=on_close)
    ws.on_open = on_open
    ws.run_forever()
