【中文标题】当用户是角色 discord.py 时,头像命令给出错误【英文标题】:Avatar command give error when the user is a role discord.py 【发布时间】:2021-12-19 04:19:15 【问题描述】:我正在创建一个头像命令,该命令有效,但我不知道如何在成员是角色或成员不是成员时给出错误。谢谢。
我的代码:
@client.command(aliases=["av","useravatar","usericon","userav","icon"])
async def avatar(ctx, *, avamember : discord.Member=None):
try:
if avamember == None:
Author = ctx.author
userAvatarUrl = Author.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"Author's avatar.",
description = f"**Links :** \n[Default](userAvatarUrl) \n[PNG](png) \n[JPG](jpg)",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by ctx.author at current_time")
await ctx.reply(embed=embed, mention_author=False)
else:
userAvatarUrl = avamember.avatar_url
stringUrl = str(userAvatarUrl)
png = stringUrl.replace("webp","png")
jpg = stringUrl.replace("webp","jpg")
embed = discord.Embed(title = f"avamember's avatar.",
description = f"**Links :** \n[Default](userAvatarUrl) \n[PNG](png) \n[JPG](jpg)",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by ctx.author at current_time")
await ctx.reply(embed=embed,mention_author=False)
except:
embed = discord.Embed(title = f"ERROR!",
description = f"An error acurred, please try again.",
color = 0xf461ff)
embed.set_image(url=userAvatarUrl)
now = datetime.now()
current_time = now.strftime("%H:%M")
embed.set_footer(text=f"Requested by ctx.author at current_time")
await ctx.reply(embed=embed,mention_author=False)
我得到的错误:

【问题讨论】:
确保这是正确的角色 ID 【参考方案1】:您可以执行if
语句来检查该成员是否在服务器中。

return await ctx.send("That member is not valid!")
【讨论】:
我在命令上加上if语句,只是让命令只能用于命令的作者,不能用于查看他人头像。 @MenIndo 我编辑了我的答案以使其工作。以上是关于当用户是角色 discord.py 时,头像命令给出错误的主要内容,如果未能解决你的问题,请参考以下文章
从用户中删除角色,然后将它们添加回 Discord.py(使用 Repl.it)
如何使用 discord.py 机器人,在他们加入 VC 时赋予用户角色并在他们离开时将其删除
