到目前为止，我有一条消息，新用户可以在不和谐的某个频道中做出反应，该消息将根据他们选择的反应为他们分配一个角色（这部分有效）。我还希望如果他们删除了对该消息的反应，则该角色将从用户中删除（这是不起作用的）。我收到一条错误消息：第23行，在on_raw_reaction_remove中，角色=discord. utils.get（payload.成员.gul.角色，名称='War Thunder'）属性错误：'NoneType'对象没有属性'行业'
@client.event
# this works to assign a role
async def on_raw_reaction_add(payload):
# channel and message IDs should be integer:
if payload.channel_id == 700895165665247325 and payload.message_id == 756577133165543555:
if str(payload.emoji) == "<:WarThunder:745425772944162907>":
role = discord.utils.get(payload.member.guild.roles, name='War Thunder')
await payload.member.add_roles(role)
# this doesn't work in removing the role
async def on_raw_reaction_remove(self, payload):
if payload.channel_id == 700895165665247325 and payload.message_id == 756577133165543555:
if str(payload.emoji) != "<:WarThunder:745425772944162907>":
role = discord.utils.get(payload.member.guild.roles, name='War Thunder')
await payload.member.remove_roles(role)
正如留档所说，只有当event_type是REACTION_ADD时，有效成员才可用。因此，要获得公会，您必须使用payload。guild_id并且：
client.fetch_guild(): async def on_raw_reaction_remove(payload):
if payload.channel_id == 700895165665247325 and payload.message_id == 756577133165543555:
if str(payload.emoji) == "<:WarThunder:745425772944162907>":
guild = await client.fetch_guild(payload.guild_id)
role = discord.utils.get(guild.roles, name='War Thunder')
await payload.member.remove_roles(role)
async def on_raw_reaction_remove(payload):
if payload.channel_id == 700895165665247325 and payload.message_id == 756577133165543555:
if str(payload.emoji) == "<:WarThunder:745425772944162907>":
guild = discord.utils.get(client.guilds, id=payload.guild_id)
role = discord.utils.get(guild.roles, name='War Thunder')
await payload.member.remove_roles(role)
PS：不是每次都写discord. utils.get（），你可以在导入中写from discord.utils import get，然后写get（iterable，**attrs）。
