问题

所以我试图使用discord.py交互和app_commands元素向斜杠命令添加按钮，但是当我尝试运行这段代码时，我得到了这个错误：[error](https://i.stack.imgur.com/hL2Ks.png)。我找不到discord.py实现的正常示例，也许有人可以帮忙。

代码：

intents = discord.Intents.all()
client = discord.Client(intents=intents)
tree = app_commands.CommandTree(client)

@tree.command(name="hello", description="带有按钮的发送hello消息", guild=croc)
async def hello(ctx):
button1 = discord.Button(label="Hello", custom_id="hello")
button2 = discord.Button(label="World", custom_id="world")
action_row = discord.ActionRow(button1, button2)

await ctx.response.send_message("点击一个按钮！", components=[action_row])

@client.event
async def on_interaction(interaction):
if interaction.type == discord.InteractionType.component:
custom_id = interaction.data["custom_id"]

    if custom_id == "hello":
        await interaction.response.send_message("你点击了Hello按钮！", ephemeral=True)
    elif custom_id == "world":
        await interaction.response.send_message("你点击了World按钮！", ephemeral=True)

@client.event
async def on_ready():
await tree.sync(guild=croc)
print("登录为", client.user)

So I was trying to add buttons to slash commands using discord.py interactions and app_commands elements but when I try to run this code I get this error: [error](https://i.stack.imgur.com/hL2Ks.png). I can&#39;t find normal examples for discord.py implementations maybe somebody can help.

Code:

intents = discord.Intents.all()
client = discord.Client(intents=intents)
tree = app_commands.CommandTree(client)

@tree.command(name="hello", description="Sends a hello message with buttons", guild=croc)
async def hello(ctx):
button1 = discord.Button(label="Hello", custom_id="hello")
button2 = discord.Button(label="World", custom_id="world")
action_row = discord.ActionRow(button1, button2)

await ctx.response.send_message("Click a button!", components=[action_row])

@client.event
async def on_interaction(interaction):
if interaction.type == discord.InteractionType.component:
custom_id = interaction.data["custom_id"]

    if custom_id == "hello":
        await interaction.response.send_message("You clicked the Hello button!", ephemeral=True)
    elif custom_id == "world":
        await interaction.response.send_message("You clicked the World button!", ephemeral=True)

@client.event
async def on_ready():
await tree.sync(guild=croc)
print("Loged as ", client.user)

Maybe there is problem with library version but i don't know.

从[文档][1]中，可以看出，用于创建按钮的可构建和可用类型是[discord.ui.Button][2]，而不是这个。

这不是创建按钮的方法。创建一个视图类：
```python
class ButtonView(discord.ui.View):
    def __init__(self):
        super().__init__()

现在，在这之后，有两种方法可以添加按钮。

class ButtonView(discord.ui.View):
    def __init__(self):
        super().__init__()
    
    @discord.ui.button(label="Hello")
    async def buttoncallback(self, interaction: discord.Interaction, button: button: discord.ui.Button):
        pass

或者你可以动态添加它们。

class ButtonView(discord.ui.View):
    def __init__(self):
        super().__init__()
        self.add_buttons() # 记得添加这一行来调用add_buttons()函数
    def add_buttons(self):
        mybutton = discord.ui.Button(label="Hello")
        self.add_item(mybutton)

        async def buttoncallback(interaction: discord.Interaction):
            pass

        mybutton.callback = buttoncallback

要调用你的按钮，将你的ButtonView添加到发送消息时的view参数中。

@tree.command(name="hello", description="Sends a hello message with buttons", guild=croc)
async def hello(interaction: discord.Interaction):
    view = ButtonView()
    await interaction.response.send_message("Click a button!", view=view)

注意：为了不让自己混淆，将ctx更改为interaction。discord.ext.commands.Context与discord.Interaction完全不同。ctx之所以能工作，是因为你的代码认为它是interaction，并且你确实像是interaction一样使用了它。

    def __init__(self):
        super().__init__()

        pass

    def __init__(self):
        super().__init__()
        self.add_buttons() # Remember to add this line to call the add_buttons() function
    def add_buttons(self):
        mybutton = discord.ui.Button(label="Hello")
        self.add_item(mybutton)

        async def buttoncallback(interaction: discord.Interaction):
            pass

        mybutton.callback = buttoncallback
