Python从特定角色获取所有成员列表

Question

How to get a members list from a specific role with !getuser command in discord channel.

@bot.command(pass_context=True)  
async def getuser(ctx):

bot replys with their ID

 1. @user1#123
 2. @user2#123

Answer 1

The rewrite branch provides an attribute Role.members .

On the async branch, you'll have to loop through all the members of the server and check their roles.

@bot.command(pass_context=True)  
async def getuser(ctx, role: discord.Role):
    role = discord.utils.get(ctx.message.server.roles, name="mod")
    if role is None:
        await bot.say('There is no "mod" role on this server!')
        return
    empty = True
    for member in ctx.message.server.members:
        if role in member.roles:
            await bot.say("{0.name}: {0.id}".format(member))
            empty = False
    if empty:
        await bot.say("Nobody has the role {}".format(role.mention))

Answer 2

All these solutions are too inefficient when you can just do

@bot.command()
async def getuser(ctx, role: discord.Role):
    await ctx.send("\n".join(str(role) for role in role.members)

Patrick's answer doesn't work at all, Tristo's answer is better, but I tweaked a few things to make it work with rewrite:

@bot.command(pass_context=True)
@commands.has_permissions(manage_messages=True)
async def members(ctx,*args):
    server = ctx.message.guild
    role_name = (' '.join(args))
    role_id = server.roles[0]
    for role in server.roles:
        if role_name == role.name:
            role_id = role
            break
    else:
        await ctx.send("Role doesn't exist")
        return
    for member in server.members:
        if role_id in member.roles:
            await ctx.send(f"{member.display_name} - {member.id}")

Answer 4

Hopefully a faster and more readable solution than the one before

@bot.command(pass_context=True)  
async def getuser(ctx,*args):
  server = ctx.message.server
  role_name = (' '.join(args))
  role_id = server.roles[0]
  for role in server.roles:
    if role_name == role.name:
      role_id = role
      break
  else:
    await bot.say("Role doesn't exist")
    return    
  for member in server.members:
    if role_id in member.roles:
      await bot.say(f"{role_name} - {member.name}")
