discord.py 一些任务没有工作 [AttributeError: 'NoneType' object has no attribute 'send']

Question

在成功让我的前 3 个任务完美运行后，我又来了，下一个让我有些头疼.. 它的代码与我在其他任务中的代码几乎相同。

代码：

    @tasks.loop(seconds=20)
async def online_stats():
    message_channel = bot.get_channel(target_channel_id2)
    link = my_link
    f = requests.get(link)
    sys.stdout = open("test2.txt", "w")
    print(f.text)
    sys.stdout.close()
    time.sleep(0.5)
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search, replacement_text), end="")
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search2, replacement_text2), end='') 
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search3, replacement_text2), end='')
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search4, replacement_text2), end='')
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search5, replacement_text3), end='')
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search6, replacement_text4), end='')
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search7, replacement_text5), end='')
    with fileinput.FileInput(filename2, inplace=True, backup='.bak') as file:
        for line in file:
         print(line.replace(text_to_search8, replacement_text6), end='')

    with open('test2.txt') as fp:
        lines=fp.readlines()
    await message_channel.send(lines[148].strip('\n') + " " + lines[150])
    await message_channel.send(lines[156].strip('\n') + " " + lines[158].strip('\n'))
    await message_channel.send(lines[164].strip('\n') + " " + lines[166].strip('\n'))
    await message_channel.send(lines[172].strip('\n') + " " + lines[174].strip('\n'))
    await message_channel.send(lines[180].strip('\n') + " " + lines[182].strip('\n'))

控制台输出

    Unhandled exception in internal background task 'online_stats'.
Traceback (most recent call last):
  File "C:\Users\0x9\AppData\Roaming\Python\Python38\site-packages\discord\ext\tasks\__init__.py", line 101, in _loop
    await self.coro(*args, **kwargs)
  File ".\discord_bot_pi_aktuell.py", line 411, in online_stats
    await message_channel.send(lines[148].strip('\n') + " " + lines[150])
AttributeError: 'NoneType' object has no attribute 'send'

它与我用于正在运行的命令的代码基本相同，但是如果我想将代码用于任务，则它无法正常工作的原因是“AttributeError：'NoneType'对象没有属性'send”

回答每个问题！愿你们都拥有伟大的东方。

编辑：对于所有遇到相同问题的人来说，这是解决问题的解决方案：

你有一个前循环

@online_stats.before_loop
async def before():
    await bot.wait_until_ready()
    print("Finished waiting")

您收到的错误是由 API 错误引起的，您的机器人无法获得您进入的频道

message_channel = bot.get_channel(id)

您应该检查机器人当前是否可以看到该频道。如果他不在包含该频道的服务器中，则您既不能发送消息也不能获取该频道。
