websocket连接失败，进不了函数on_open和on_message

Question

websocket连接大概如下，但是运行程序时，函数on_open、on_message都没有被执行，完全没有进入？想问下是什么情况？感谢大佬告知！！！急！！！

def SendWebSocket:
    class __init__(self, file,url):
        self.file = 
        self.rul = 

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

    def on_open(self,ws):
        prnit('open')

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

    def main(self):
        ws = websocket.WebSocketApp(self.url, on_message=self.on_message, on_error=self.on_error)
        ws.on_open = self.on_open
        ws.run_forever()

    if __name__ == '__main__':
        sws = SendWebSocket(file, url)
        sws.main()
