• 问题描述

  class Something():    def on_message(self,ws, message):        pass    ...    def main(self):            websocket.enableTrace(True)            ws = websocket.WebSocketApp("wss://stream.binance.com:9443/ws/btcusdt@trade",                                    on_message = self.on_message,                                    on_error = self.on_error,                                    on_close = self.on_close)

  将websocket实例写入一个类，此时调用self.on_message出现如题问题。

• 解决方案

  class Something():    def on_message(self, message): # 将ws去掉，self占位ws        pass    ...    def main(self):            websocket.enableTrace(True)            ws = websocket.WebSocketApp("wss://stream.binance.com:9443/ws/btcusdt@trade",                                    on_message = self.on_message,                                    on_error = self.on_error,                                    on_close = self.on_close)
