問題描述

我當(dāng)前的代碼是

@client.event
async def on_member_join(member):
    serverchannel = member.server.default_channel
    msg = "Wuss poppin', {0}. Welcome to {1}".format(member.mention, member.server.name)
    await client.send_message(member.server.default_channel, msg)`

@client.event
async def on_member_remove(member):
    serverchannel = member.server.default_channel
    msg = "Well. Cya, {0}!".format(member.mention)
    await client.send_message(serverchannel, msg)

以及其他必要的行(如 import discord 等)和其他命令.

As well as the other necessary lines (like import discord etc.) and other commands.

當(dāng)成員加入或離開時，我收到此錯誤:

When a member joins or leaves, I get this error:

Ignoring exception in on_member_join
Traceback (most recent call last):
  File "C:UsersWillLAppDataLocalProgramsPythonPython36libsite-packagesdiscordclient.py", line 307, in _run_event
    yield from getattr(self, event)(*args, **kwargs)
  File "C:/Users/WillL/Desktop/MemzBot-master/index.py", line 102, in on_member_join
    await client.send_message(member.server.default_channel, msg)
  File "C:UsersWillLAppDataLocalProgramsPythonPython36libsite-packagesdiscordclient.py", line 1145, in send_message
    channel_id, guild_id = yield from self._resolve_destination(destination)
  File "C:UsersWillLAppDataLocalProgramsPythonPython36libsite-packagesdiscordclient.py", line 289, in _resolve_destination
    raise InvalidArgument(fmt.format(destination))
discord.errors.InvalidArgument: Destination must be Channel, PrivateChannel, User, or Object. Received NoneType

我不明白為什么，我錯過了什么?

I don't understand why, what am I missing?

推薦答案

默認頻道不再存在.這意味著兩件事:

1. server.default_channel 可能返回 NoneType.
2. 嘗試向 server 發(fā)送消息可能會引發(fā) discord.NotFound.

1. server.default_channel may return a NoneType.
2. Trying to send a message to server may raise discord.NotFound.

這些情況將發(fā)生在 8 月 3 日之后創(chuàng)建的任何服務(wù)器上，或者任何已刪除其默認"頻道的服務(wù)器上.

These cases will happen on any servers created after August 3rd, or any servers who have deleted their "default" channel.

您需要自己選擇一個頻道，或者要求服務(wù)器為歡迎消息設(shè)置一個頻道.您仍然可以嘗試發(fā)送到服務(wù)器，但請確保您有一個失敗的后備選項.

You need to either choose a channel yourself, or ask the server to set a channel for the welcome message. You can still attempt to send to the server, but make sure you have a fall back option if it fails.

這篇關(guān)于Discord.py member.server_default_channel 中的參數(shù)無效的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
