Question

我正在尝试为我的机器人创建一个命令，该命令允许用户进行错误报告，但是在尝试运行代码时，我总是遇到错误。

@client.command()
async def bug(ctx, author, message, m):
    await ctx.send("Greetings! What would you like to report?")
    return m.author == message.author and m.channel == message.channel
    msg = await client.wait_for('message', check=bug)
    bugReport = msg[2:]
    await ctx.send("Thank you for your help. This bug has been reported to the server admins.")
    channel = client.get_channel(private)
    await channel.send(bugReport + " was reported by " + author)

该程序应该在询问用户错误消息之前先询问他们想要报告什么，然后切换到错误报告通道以报告问题，但是，我得到的只是错误：

discord.ext.commands.errors.MissingRequiredArgument: author is a required argument that is missing.

Answer 1

该错误表明缺少必需的参数author。

上面的代码中有3个author参数：

在功能def bug(ctx, author, message, m)
在参数m.author
在参数message.author

在代码中添加一些if author is not None:语句以检查author参数是否存在，如果不需要，默认情况下将其设置为None：

def bug(ctx, author=None, message, m):
    # Some code here...
    if author is not None:
        await channel.send(bugReport + " was reported by " + author)
    else:
        await channel.send(bugReport)  # without author

P.S。在return声明之后：

return m.author == message.author and m.channel == message.channel

bug函数的其余部分将不会执行（无用）。

您正在重用名称bug来同时引用命令本身和对wait_for的检查。看起来您正在尝试在函数中定义检查，但缺少定义行。

您似乎希望在调用命令时将author和message（以及m，无论是什么）传递给协程。而是将它们捆绑到单个Context对象中，这是第一个参数。

下面，我修改了您的代码，以便可以从初始调用中提取report，也可以要求它。

@client.command()
async def bug(ctx, *, report):
    def check(message):
        return ctx.author == message.author and ctx.channel == message.channel

    if not report:
        await ctx.send("Greetings! What would you like to report?")
        msg = await client.wait_for('message', check=check)
        report = msg.content[2:]  # This doesn't look right to me, will remove 2 characters
    await ctx.send("Thank you for your help. This bug has been reported to the server admins.")
    channel = client.get_channel(private)
    await channel.send(report + " was reported by " + author)

如何解决“ discord.ext.commands.errors.MissingRequiredArgument：author是缺少的必需参数”。不一致
