問題描述

我正在向我的 Discord 機器人添加個人資料卡，但我遇到了一個問題.當有人鍵入 !profile @user 我不確定如何正確解析 @user 以便機器人知道要查找哪個個人資料卡.

I am adding profile cards onto my Discord bot, but I've come across one issue. When someone types !profile @user I am not sure how to properly parse for @user so the bot knows which profile card to lookup.

我首先解析 message.content，然后刪除消息內(nèi)容的前 9 個字符(始終是 !profile)，但消息內(nèi)容的其余部分返回看起來 < 的 user_id;@289583108183948460> 而不是用戶的歧視.我曾嘗試使用 re.sub 刪除特殊字符(@、> 和 <)，如下所示:

I first parse message.content and then remove the 9 first chars of the message content (which is always !profile) but the rest of the message content returns the user_id which looks <@289583108183948460> instead of the user's discrim. I have tried using re.sub to remove the special characters (@, >, and <) like this:

a = str(message.content[9:])
removeSpecialChars = re.sub("[!@#$%^&*()[]{};:,./<>?|`~-=_+]", " ", a)
print(removeSpecialChars)

但是當我只想要數(shù)字時，奇怪的字符仍然存在，因此我可以輕松地在數(shù)據(jù)庫中搜索它.我確信有更好的方法可以做到這一點，但我想不通.

But the weird characters are still there when I only want the number so I can search it in the database easily. I'm sure there's a way better way to do this though but I can't figure it out.

推薦答案

discord.py 的消息對象包含 Message.mentions 屬性，因此您可以遍歷 Member.以下是 async 和 的文檔列表 rel="nofollow noreferrer">重寫.

discord.py's message objects include a Message.mentions attribute so you can iterate over a list of Member. Here are the doc listings for async and rewrite.

有了這個，你可以簡單地迭代提及:

With this you can simply iterate over the mentions as so:

for member in ctx.message.mentions:
    # do stuff with member

你真正想要的

discord.py 允許您從帶有 discord.Member 對象"nofollow noreferrer">類型提示.只需將以下內(nèi)容添加到命令中

what you actually want

discord.py allows you to grab discord.Member objects from messages with type hinting. simply add the following to the command

@bot.command()
async def profile(ctx, member: discord.Member=None):
    member = member or ctx.message.author
