Question

我正在努力保持与fxcmp api（fxcmpy）的连接持续有效一段时间后，连接断开，当代码尝试重新连接时，我收到以下错误消息。

我尝试了几种方法来恢复连接，但似乎没有任何作用

有人知道这里出什么问题吗？

|ERROR|2020-10-21 16:05:53,815|Socket returns unknown error.

示例代码：

class Data():
    def __init__(self):
        self.time = None
        self.last_data = None
    
    
    def update(self, data, dataframe):
        self.time = pd.to_datetime(int(data['Updated']), unit='ms')
        self.last_data = data['Rates']
        

def run(data, con):

    while con.is_connected():
        try:
            time.sleep(1)

            print(data.time, data.last_data)
        
        except KeyboardInterrupt:
            con.close()
            raise SystemExit

    con.logger.info('lost connection') 
    con.close()
    start_up()

def setup_con():

    con = fxcmpy.fxcmpy(log_file=f"logs/test.log",
                        log_level='debug',
                        access_token='',
                        server='real')

    return con

def start_up():
       
    flag = False

    while not flag:
        try:
            con = setup_con()
            data = Data()
            con.subscribe_market_data('EUR/USD', (data.update,))
            con.logger.info("Setup complete")
            flag = True
            run(data, con)
 
        except Exception:
            print('error in reinitialization')
            con.logger.exception('error in reinitialization')
      

if __name__ == '__main__':
    start_up()

fxcmpy连接断开，无法重新连接
