如何获得要添加到用户的角色

Question

我一直在尝试编写一个不和谐机器人，我正在努力为某人添加一个角色。我已经通读了几个主题，但似乎没有一个解决方案对我有帮助。

当前，当添加反应时，我将获得角色，稍后我将向用户添加角色。我有一个名为member的角色，我得到了一个错误。这是我的代码

@bot.event
async def on_raw_reaction_add(payload):
channel_id = 888832144607166505
post_cid = payload.channel_id
reactor = await bot.fetch_user(payload.member)
if channel_id == post_cid:
print('Reaction added.', reactor)
role = await discord.utils.get(reactor.server.roles, name="Member")
print(role)

这是我的错误

Traceback (most recent call last):

File "c:UsersHomeDocumentsMandAStudiosbot.py", line 44, in on_raw_reaction_add

您的代码中有reactor = await bot.fetch_user(payload.member)，这是错误的。您提供了一个成员对象，而不是成员id，这是实参所需要的。

所以你需要把它改成reactor = await bot.fetch_user(payload.member.id)

除此之外，你没有给任何人分配一个角色，你的await在角色定义上是错误的。

@bot.event
async def on_raw_reaction_add(payload):
channel_id = 888832144607166505
post_cid = payload.channel_id
# Get reactor with id, without an API request
reactor = payload.guild.get_member(payload.member.id)
if channel_id == post_cid:
print('Reaction added.', reactor)
# get guild by id
guild = bot.get_guild(int(payload.guild_id))

# get role

role = discord.utils.get(guild.roles, name="Member")
print(role)
# add role to reactor

await reactor.add_roles(role, reason="self-role reaction")

正确的方法是使用guild.get_member(payload.member.id)并确保您的bot具有相关权限Src

@bot.event
async def on_raw_reaction_add(payload):
channel_id = 888832144607166505
post_cid = payload.channel_id
if channel_id == post_cid:
guild = bot.get_guild(int(payload.guild_id))
role = discord.utils.get(guild.roles, name="Member")
print(role)
member = guild.get_member(payload.member.id)
await member.add_roles(role, reason="self-role reaction")
