Discord机器人通过用户ID发私信报错：Client无get_user_info成员

Hey there! That pylint error is popping up because the get_user_info method you're using is deprecated and removed in modern versions of discord.py (v1.0+). Let's get your DM functionality working correctly.

What to Use Instead #

Discord.py replaced get_user_info with two more precise methods:

• client.fetch_user(user_id): Fetches user data directly from the Discord API. Use this if you need to message a user who isn't in any server shared with your bot, or if you want the most up-to-date user info. This requires await since it's an asynchronous API call.
• client.get_user(user_id): Pulls user data from the bot's local cache. Use this for users who are in at least one server with your bot—it's faster and doesn't need await.

Corrected Code Example #

Here's how to rewrite your code to send a DM properly:

@client.event
async def on_message(message):
    # Avoid responding to the bot's own messages to prevent loops
    if message.author == client.user:
        return

    if message.content.lower() == 'dm':
        # Replace this with the actual user ID (integer, not a string)
        target_user_id = 123456789012345678
        try:
            # Fetch the user (works for any user, even outside shared servers)
            user = await client.fetch_user(target_user_id)
            # Send the DM directly via the user object
            await user.send("Your message")
            print("DM sent successfully!")
        except discord.NotFound:
            print("Error: That user doesn't exist, or the bot can't access them.")
        except discord.Forbidden:
            print("Error: The bot doesn't have permission to send a DM to this user.")

Key Notes #

• User ID Format: The user ID should be an integer, not a string. Remove the quotes around "USER'S ID" and replace it with the numerical ID.
• Error Handling: Adding try/except blocks helps catch common issues like invalid user IDs or missing permissions.
• Cache vs API: Use get_user if you know the user is in a shared server (no await needed), otherwise stick with fetch_user.
