discord.py on member join ，给出角色命令

Question

所以我做了一个命令，可以设置一个成员加入，给角色命令，它将它存储到一个 json 文件中。但是当有人加入时会出现错误：return self._roles.get(role_id) TypeError: unhashable type: 'list'。这是我的代码：

with open('join_roles.json', 'r') as f:
  join_roles = json.load(f)

@client.event
async def on_member_join(member):
  guild = member.guild
  print(join_roles.get(str(guild.id)))
  role = member.guild.get_role(join_roles.get(str(guild.id)))
  await member.add_roles(role)

@client.command()
@commands.has_permissions(administrator=True)
async def joinrole(ctx, role):
  join_roles[str(ctx.guild.id)] = role.split()
  with open('join_roles.json', 'w') as f:
    json.dump(join_roles, f)
  await ctx.send(embed=discord.Embed(title=f':white_check_mark:| Member join role set to {role}!', color=0x2596be))

Answer 1

所以join_roles.get(str(guild.id)) 返回一个list，这对guild.get_role() 不起作用。这可能表明您的 json 数据显示如下：

{
    "GuildID": ["RoleID"]
}

由于 join_roles[str(ctx.guild.id)] = role.split() 将列表放入 json 数据中。一个更好的解决方案是使用返回 Role 的 RoleConverter，这将允许角色：ID、角色提及和角色名称。

with open('join_roles.json', 'r') as f:
  join_roles = json.load(f)

@client.event
async def on_member_join(member):
  guild = member.guild
  print(join_roles.get(str(guild.id)))
  role = member.guild.get_role(join_roles.get(str(guild.id)))
  await member.add_roles(role)

@client.command()
@commands.has_permissions(administrator=True)
async def joinrole(ctx, role):
  role = await commands.RoleConverter().convert(ctx, role)
  join_roles[str(ctx.guild.id)] = role.id
  with open('join_roles.json', 'w') as f:
    json.dump(join_roles, f)
  await ctx.send(embed=discord.Embed(title=f':white_check_mark:| Member join role set to {role.name}!', color=0x2596be))
