discord.py报表系统discord.py \ MissingRequiredArgument

Question

好的，我想我把正确的代码写下来了，但我不知道该用什么论据。如果有人能帮忙，请帮忙。

代码：

@client.command()
async def report(ctx, *, report):
  # values
  user = ctx.author
  server = ctx.guild.name
  channel = client.get_channel(1009201586586783785)
  # Report Text
  if report == None:
      # Error
      await ctx.send("Enter your report! example : r!report {your report here}")
  else:
      # Success
      await ctx.send("We have sent your report to **DisReport Hub** to be reviewed!")
      report = discord.Embed(title=f"{user.name} sent an report!", description="-----", color=discord.Colour.blurple())
      report.add_field(name=f"Report from - {server}: ", value=f"{report}")
      await channel.send(embed=report)

错误消息：

 line 542, in transform
    raise MissingRequiredArgument(param)
discord.ext.commands.errors.MissingRequiredArgument: report is a required argument that is missing.

如果想让它默认，则需要显式地给它默认的None。否则，它将给出异常，这将导致错误被打印到控制台，如果它还没有被处理。

@client.command()
async def report(ctx, *, report: str = None):
  # values
  user = ctx.author
  server = ctx.guild.name
  channel = client.get_channel(1009201586586783785)
  # Report Text
  if report is None:  # sidenote: prefer `is` when comparing to `None`
      # Error
      await ctx.send("Enter your report! example : r!report {your report here}")
  else:
      # Success
      await ctx.send("We have sent your report to **DisReport Hub** to be reviewed!")
      report = discord.Embed(title=f"{user.name} sent an report!", description="-----", color=discord.Colour.blurple())
      report.add_field(name=f"Report from - {server}: ", value=f"{report}")
      await channel.send(embed=report)
