Creating Button Roles | TypeError: button_callback() missing 1 required positional argument: 'member' | Discord.py/Pycord

Question

我正在尝试为我的 Discord 服务器创建按钮角色，但在这样做时遇到了错误。

代码：

@client.command()
async def test(ctx):
    button= Button(label= "Click Below", style= discord.ButtonStyle.green, emoji= "<a:Tada:944187121495863327>")
    async def button_callback(interaction, member: discord.Member):
        role = discord.utils.get(ctx.guild.roles, id = 944152100823261205) 
        member.id= interaction.user.id
        await member.add_role(role)
        
    button.callback= button_callback

    view= View(button)
    await ctx.send("React", view=view)

终端输出：

Ignoring exception in view for item <Button style=<ButtonStyle.success: 3> url=None disabled=False label='Click Below' emoji= row=None>: Traceback (most recent call last):
File "C:\Users\USER\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ui\view.py", line 371, in _scheduled_task await item.callback(interaction) TypeError: button_callback() missing 1 required positional argument: 'member'

过去 2 天我一直在努力解决这个问题，非常感谢您的帮助:)

说明

您收到错误是因为您尝试向回调添加参数，而当 discord 调用它时，它没有通过 member。

按钮回调只传递一个参数：与之关联的 Interaction。您可以通过Interaction.user.

代码

@client.command()
async def test(ctx: commands.Context):
    button = Button(label="Click Below", style=discord.ButtonStyle.green, emoji="<a:Tada:944187121495863327>")

    async def button_callback(interaction: discord.Interaction):
        role = ctx.guild.get_role(944152100823261205)
        member = ctx.guild.get_member(interaction.user.id)
        await member.add_roles(role)

    button.callback = button_callback

    view = View(button)
    await ctx.send("React", view=view)

参考

Interaction.user

Button.callback
