RuntimeWarning：从未等待协程“MessageMethods.send_message”

Question

import random
from telethon import TelegramClient, events


def main():
    api_id = 9123640
    api_hash = '8as6fgvs8t9ar76fse89rgearz'
    chat = '@username'
    message = 'hi'

    client = TelegramClient('afewfe', api_id, api_hash)

    @client.on(events.NewMessage(chats=chat))
    async def normal_handler(event):
        if event.message.button_count == 4:
            await event.message.click(random.randint(0, 3))
            await client.disconnect()

    client.start()
    client.send_message(chat, message)
    client.run_until_disconnected()


if __name__ == '__main__':
    main()

我想向用户发送消息，然后使用 4 个按钮从用户消息中返回，单击随机按钮并停止脚本。发送消息的问题。如果我评论client.send_message(chat, message)行并自己发送消息，代码将继续正常工作，但client.send_message(chat, message)行出现错误：

RuntimeWarning: coroutine 'MessageMethods.send_message' was never awaited
  client.send_message('@username', 'hi')
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

如何解决这个问题？

Answer 1

看起来您正在正常函数中运行异步代码。该错误抱怨client.send_message(chat, message) 代码前面没有await 关键字。为了能够以您想要的方式运行任何异步函数（就像普通的函数调用一样），您必须在函数调用的代码之前有 await 关键字。为了能够在不引发错误的情况下使用 await 关键字，保存代码 (main) 的外部函数需要是异步的，并且可以使用 asyncio.run 运行。

from asyncio import run

async def main():
    # your code

    client.start()
    client.run_until_disconnected()
    await client.send_message(chat, message)

if __name__ == "__main__":
    run(main())

Answer 2

import random
from telethon import TelegramClient, events
from asyncio import run


async def main():
    api_id = 9123640
    api_hash = '8as6fgvs8t9ar76fse89rgearz'
    chat = '@username'
    message = 'hi'

    client = TelegramClient('afewfe', api_id, api_hash)

    @client.on(events.NewMessage(chats=chat))
    async def normal_handler(event):
        if event.message.button_count == 4:
            await event.message.click(random.randint(0, 3))
            await client.disconnect()

    client.start()
    await client.send_message(chat, message)
    client.run_until_disconnected()

if __name__ == "__main__":
    run(main())

完全错误：
