如何根据ping做出bot回复?(短信)

Question

我在Python中制作一个Discord bot，我想添加一个功能，当我使用命令_throw和ping用户时，bot将根据用户ping回复(它最好是通常的文本消息，而不是)嵌入)。目前，我有这个代码:

if message.content == "_throw":
user = message.mentions[0]
await message.channel.send("You threw a hamster to " + f"{user}" + "!")

但是我的bot根本没有回复它(PyCharm没有看到任何错误)。

这是我的bot脚本:

@client.event
async def on_message(message):
if message.author == client.user:
return
if message.content.startswith('_hi'):
await message.channel.send(f'Hello, {message.author.mention}!')
if message.content == "_throw":
user = message.mentions[0]
await message.channel.send("You threw hamster to " + f"{user}" + "!")
if message.content.startswith("_userinfo"):
user = message.mentions[0]
emb14 = discord.Embed(
title=f"@{user} info:",
colour=discord.Colour.dark_blue()
)
emb14.set_image(url=user.avatar_url)
emb14.add_field(name=f"Name", value=f"{user}", inline=True)
emb14.add_field(name=f"Discord Joined date", value=f"{user.created_at}", inline=False)
emb14.add_field(name=f"Server Joined date", value=f"{user.joined_at}", inline=False)
emb14.add_field(name="Profile Picture", value=":arrow_down: :arrow_down: ", inline=False)
await message.channel.send(embed=emb14)
client.run('TOKEN')

任何想法?

我理解您希望您的bot响应_throw @user。在这种情况下，当您检查message.content == "_throw"时，它过滤的消息恰好是_throw而不是@user部分。

要接受user - mention参数，最简单的方法是使用regex匹配:

import re
# First checks if there are any mentions in the message
# Then uses regex "^_throws+<@!?[0-9]{17,22}>$" to match the message content
if message.mentions and re.match(r"^_throws+<@!?[0-9]{17,22}>$", message.content):
user = message.mentions[0]
await message.channel.send(f"You threw a hamster to {user.mention)!")

这将允许bot回复_throw @user并回复You threw a hamster to @user!
