锁定命令 discord.py答案

【问题标题】：Lock command discord.py锁定命令 discord.py

【问题描述】：

我发出了一个锁定命令，但是当fl.lock #general test 用于#general 频道时，它不会锁定通用频道，但当fl.lock #general test 用于#staff-chat 频道时，它会锁定#general 频道

因此，当 lock 命令中提到该频道并且在同一频道中使用该频道时，我的机器人不会锁定频道

代码

  @commands.command(case_insensitive = True)
  @commands.has_any_role(885434191783788564, 856071314740740096, 856061783722426378, 856465667296985108)
  async def lock(self, ctx, channel: discord.TextChannel, *, reason=None): 
    channel = channel or ctx.channel
    overwrite = channel.overwrites_for(ctx.guild.default_role)
    if overwrite.send_messages == True:
      overwrite.send_messages = False
      await channel.set_permissions(ctx.guild.default_role, overwrite=overwrite)
      em_reason = discord.Embed(title="**Channel locked**", description=f":lock: {reason}",color=discord.Color.red())
      embed = discord.Embed(description = f"<a:fl_check:874522235879186483> Locked channel <#{channel.id}>",color=discord.Color.green())
      await ctx.send(embed=em_reason)
      await ctx.send(embed=embed)
    elif overwrite.send_messages == False:
      em = discord.Embed(description="<a:fl_no:874522273984442420> That channel is already locked.", color=discord.Color.red())
      await ctx.send(embed=em)```

我认为channel = channel or ctx.channel 是这里的问题。

您应该直接检查channel 参数是否为None，而不是使用ctx.channel。

@commands.command(case_insensitive = True)
  @commands.has_any_role(885434191783788564, 856071314740740096, 856061783722426378, 856465667296985108)
  async def lock(self, ctx, channel: discord.TextChannel=None, *, reason=None): 
    if channel is None:
       channel = ctx.channel
    overwrite = channel.overwrites_for(ctx.guild.default_role)
    if overwrite.send_messages == True:
      overwrite.send_messages = False
      await channel.set_permissions(ctx.guild.default_role, overwrite=overwrite)
      em_reason = discord.Embed(title="**Channel locked**", description=f":lock: {reason}",color=discord.Color.red())
      embed = discord.Embed(description = f"<a:fl_check:874522235879186483> Locked channel <#{channel.id}>",color=discord.Color.green())
      await ctx.send(embed=em_reason)
      await ctx.send(embed=embed)
    elif overwrite.send_messages == False:
      em = discord.Embed(description="<a:fl_no:874522273984442420> That channel is already locked.", color=discord.Color.red())
      await ctx.send(embed=em)
