我的不和谐机器人如何发送欢迎信息并提供角色

Question

I want that my discord bot sends a message on a specific channel and give a specific role everytime a new user joins the server

But my bot is doing nothing and I'm getting no errors

import discord
from keep_alive import keep_alive



class MyClient(discord.Client):


    #Beim Einloggen
    async def on_ready(self):
        print("BOT is online")

    async def on_member_join(member):
      role = discord.utils.get(member.server.roles, id=<role_id>)
      channel = MyClient.get_channel(<channel_id>)
      await MyClient.add_roles(member, role)
      await channel.send(f"Hello {member} nice to see you!")

Answer 1

Code for the user greeting (in a cog):

@commands.Cog.listener()
async def on_member_join(self, member):
    channel = member.guild.system_channel
    if channel is not None:
        await channel.send(f"Welcome to the server {member.mention}!")

Basically, you are missing theese @commands.Cog.listener() 's

Answer 2

Try this! (This isn't used in a cog)

@client.event
async def on_member_join(member):

  if member.guild.id !=<YOUR_GUILD_ID>:    
    return 
  welcomerole = discord.utils.get(guild.roles, name="<ROLE_NAME>")
  await member.add_roles(welcomerole)
  channel = client.get_channel(<WELCOME_CHANNEL_ID)
  await channel.send("<WHAT_YOU_WANT>") 

This makes it so when someone joins YOUR server it will send a custom message of your choice to the welcome channel

MAKE SURE YOU ADD YOUR GUILD ID IN <YOUR_GUILD_ID>

MAKE SURE YOU ADD A CUSTOM MESSAGE WHEN A MEMBER JOINS IN <WHAT_YOU_WANT>

MAKE SURE YOU ADD YOUR WELCOME CHANNEL ID IN <WELCOME_CHANNEL_ID>

MAKE SURE YOU ADD THE ROLE NAME THAT YOU GET WHEN A MEMBER JOINS IN <ROLE_NAME>
