python - Discord.py(重写): Error Handling “Improper Token” In Function

Question

我觉得我缺少解决此问题的简单方法，但似乎找不到解决discord.errors.LoginFailure: Improper token has been passed.错误的方法。我想做的是运行一个实际上运行机器人的函数，如果遇到任何错误(使用try:和except:)并且如果捕获到“不正确的 token ”错误，则重复自身，然后更改代码中的设置并重试它。

我相信正在发生的事情是try/except没有捕获错误，并且停止了程序(在过程中打印整个错误)。我已经尝试了一些快速的解决方案，例如将函数制作为while语句，直到到达程序末尾，它将不断重复自身，但是如果没有捕获错误，我将无法继续执行任何代码。

我的代码杂乱无章，并且与这个大型python文件中较早定义的许多变量有关，因此我不会展示我的整个函数。

这是简化版:

def code(mainText):
    mainLines = mainText.split("\n")
    # Do some stuff editing mainText
    final = "\n".join(mainLines)
    try:
        exec(final, globals())
    except Exception as e:
        print(str(e))
        # edit 'final' a bit
        exec(final, globals())

完整的错误消息:

Task exception was never retrieved
future: <Task finished coro=<Client.start() done, defined at E:\DiscordBot\lib\site-packages\discord\client.py:526> exception=LoginFailure('Improper token has been passed.')>
Traceback (most recent call last):
  File "E:\DiscordBot\lib\site-packages\discord\http.py", line 258, in static_login
    data = await self.request(Route('GET', '/users/@me'))
  File "E:\DiscordBot\lib\site-packages\discord\http.py", line 222, in request
    raise HTTPException(r, data)
discord.errors.HTTPException: 401 UNAUTHORIZED (error code: 0): 401: Unauthorized

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "E:\DiscordBot\lib\site-packages\discord\client.py", line 542, in start
    await self.login(*args, bot=bot)
  File "E:\DiscordBot\lib\site-packages\discord\client.py", line 400, in login
    await self.http.static_login(token, bot=bot)
  File "E:\DiscordBot\lib\site-packages\discord\http.py", line 262, in static_login
    raise LoginFailure('Improper token has been passed.') from exc
discord.errors.LoginFailure: Improper token has been passed.

在撰写本文时，我发现“从未检索到任务异常”是否很重要，或者是常见的“标记不当”错误？

谢谢您，对于我的不良编码习惯以及缺乏使用Stack Overflow的经验，表示抱歉。

尝试这个。我自己还没有尝试过。这是我从您的问题和错误消息中可以理解的最佳答案:

#Put this at the bottom of your .py file
try:
    bot.run(BOT_TOKEN)
except discord.errors.LoginFailure as e:
    print("Login unsuccessful.")
