您需要获取有关频道、聊天、群组的信息。由于每个账号都有接收信息的限制，所以我会使用几个账号。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):

TypeError: 'coroutine' object is not callable

因为TelegramClient.start它是一个异步函数，所以你必须这样await做：

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

我对您的代码做了两个显着的更改：

  1. create_client(number)将调用包装在asyncio.as_completed. 原因是它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) 返回一个迭代器，其值为协程。

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.
  1. 更改loop.close()为loop.stop(). 否则循环将被关闭，当仍有正在运行的任务时我们将得到异常。

以下是我编辑您的代码以使其工作的方式：

import logging
from telethon import TelegramClient,sync, utils, errors
from telethon.tl.types import PeerUser, PeerChat
from telethon import functions, types

filename_excel = "project_for_export_no_formulas_31_10_18.xlsx"
filename_numbers = "number.txt"

queue_entity = asyncio.Queue()
numbers = []
count_thread = 8

def load_numbers(filename):
    with open(filename, "r") as file:
        content = file.read().split("\n")

    data = pd.read_excel(output_filename, 'Projects', dtype=str)
    for item in data["Telegram link"]:
        if item != "nan":
            queue_entity.put_nowait(item)


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

    result = None
    try:

    for f in asyncio.as_completed([asyncio.ensure_future(create_client(number)) for number in numbers]):
        client = await f
        while queue_entity.qsize() > 0:
            futures.append(asyncio.ensure_future(parse_entity(queue_entity.get_nowait(), client)))
    if futures:
        await asyncio.wait(futures)

async def start_main(root):
    loop = asyncio.get_event_loop()
    initial_future = loop.create_future()
    initial_future.set_result(root)
    await crawl(initial_future)

if __name__ == '__main__':
    start = time.time()
    load_numbers(filename_numbers) #Загрузка телефонов
    #load_excel(filename_excel)     #Загрузка Excel
    loop = asyncio.get_event_loop()

    finally:
        loop.stop()
    log.info("Time work: %s", time.time() - start)

我希望它有所帮助。
