Python asyncio websocket ConnectionClosed

Question

我有多个使用websocket的任务。我想检测websocket的连接关闭，然后重新连接websocket，我通过一个名为break_task的变量做它，如果它是真的那么在任务中有一个连接关闭检测，在代码下面和我得到的错误异常（我使用python 3.6）：

break_task = False

async def value_1():
    global break_task
    msg_dict = deepcopy(MESG)
    async with websockets.connect('wss://api.xxxxx') as ws:
        await ws.send(json.dumps(msg_dict))
        while break_task == False:
            try:
                res = await ws.recv()
            except ConnectionClosed:
                print('CONNECTION CLOSED raised exception in value_1() -> TRYING TO RECONNECT !!!')
                break_task = True
                break

async def value_2():
    global break_task
    auth_dict = deepcopy(PAYLOAD)   
    async with websockets.connect('wss://api.xxxxx') as ws:
        await ws.send(json.dumps(auth_dict))
        while break_task == False:
            await asyncio.sleep(0.05)
            try:
                res = await ws.recv()
            except ConnectionClosed:
                print('CONNECTION CLOSED raised exception in value_2() -> TRYING TO RECONNECT !!!')
                break_task = True
                break
            data = json.loads(res)

和...

while True:   
    if (break_task == False):
        tasks = value_1(), value_2()
        loop = asyncio.get_event_loop()
        loop.run_until_complete(asyncio.gather(*tasks))
    elif (break_task == True):
        tasks = None
        loop.stop()
        loop.close()
        break_task = False

我得到了这个结果：
