Question

您需要获取有关频道，聊天，群组的信息。由于每个帐户在接收信息方面都有限制，因此我将使用多个帐户。我正在尝试获取信息，但出现错误：

 Traceback (most recent call last):
  File "D:/Git/telegram/telegram_new.py", line 50, in parse_entity
    channel=entity
TypeError: 'coroutine' object is not callable

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/Git/telegram/telegram_new.py", line 56, in parse_entity
    id=entity
TypeError: 'coroutine' object is not callable

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "D:/Git/telegram/telegram_new.py", line 60, in parse_entity
    chat_id=entity
TypeError: 'coroutine' object is not callable

Answer 1

由于TelegramClient.start是一个异步函数，因此您必须await：

async def create_client(number):
    return await TelegramClient(number, api_id, api_hash).start()

我对您的代码进行了两项显着更改：

在create_client(number)中包装asyncio.as_completed呼叫。原因是create_client(number)返回一个协程对象，但是asyncio.as_completed需要一个期货列表。这是as_completed文档字符串：

as_completed（fs，*，loop = None，timeout = None）返回其值为协程的迭代器。

When waiting for the yielded coroutines you'll get the results (or
exceptions!) of the original Futures (or coroutines), in the order
in which and as soon as they complete.

This differs from PEP 3148; the proper way to use this is:

    for f in as_completed(fs):
        result = await f  # The 'await' may raise.
        # Use result.

将loop.close()更改为loop.stop()。否则，循环将关闭，并且当仍有正在运行的任务时，我们将获得异常。

这是我修改您的代码以使其正常工作的方式：
