Discord.py按钮

Question

所以我想发送一个带有“我加入”的按钮的嵌入，用户可以点击它，这样一个邀请就会在 JSON 文件中下降 go

这是我的代码：

@client.command()
async def post(ctx, *, content="!"):
    await ctx.channel.purge(limit=1)
    with open("bot-info.json", "r") as f:
        bot_data = json.load(f)


    DISCORD_API_LINK       = "https://discordapp.com/api/invite/"
    DISCORD_GET_IMAGE_LINK = "https://cdn.discordapp.com/icons/"

    channel = client.get_channel(bot_data["nft_projects_channel"])

    if len(content.split(";")) == 3:
        LINK, DESCRIPTION, INVITES = content.split(";")

        invite_code = LINK.split("/")[-1]
        async with aiohttp.ClientSession() as session:
            async with session.get(DISCORD_API_LINK + invite_code) as response:
                data = await response.text()
                json_data = json.loads(data)
                
                try:
                    SERVER_NAME = json_data["guild"]["name"]
                    SERVER_ID   = json_data["guild"]["id"]
                    if json_data["expires_at"] != None:
                        msg = await ctx.send("Warning! invitation has an expiration date, snd an invitation without an expiration date.")
                        await asyncio.sleep(6)
                        await msg.delete()
                        return None
                    try:
                        json_data["inviter"]
                    except:
                        embed = discord.Embed(title="Error", description="Invite Link is not unique", color=0xF54245)
                        msg = await ctx.send(embed=embed)
                        await asyncio.sleep(6)
                        await msg.delete()
                        return None
                    SERVER_ICON = str(DISCORD_GET_IMAGE_LINK + SERVER_ID + "/" + json_data["guild"]["icon"] + ".png")
                except:
                    embed = discord.Embed(title="Error", description="Check invite link", color=0xF54245)
                    msg = await ctx.send(embed=embed)
                    await asyncio.sleep(6)
                    await msg.delete()
                    return None

        with open("all-servers.json", "r") as read_file:
            data = json.load(read_file)

        if not SERVER_ID in data:
##################################################################################################
            embed = discord.Embed(title = SERVER_NAME, url=LINK, description = DESCRIPTION, color=0xE659ff) #This embed should have the button

            embed.add_field(name="Link:", value=LINK, inline=False)
            embed.add_field(name="Invites Requird:", value=INVITES, inline=False)

            embed.set_thumbnail(url=SERVER_ICON)
            
            await channel.send(embed=embed) #here I am sending it
##################################################################################################

            data[SERVER_ID] = {}
            data[SERVER_ID]["SERVER ID"] = SERVER_ID
            data[SERVER_ID]["INVIRES NEEDED"] = int(INVITES)

            with open("all-servers.json", "w") as write_file:
                json.dump(data, write_file, indent=4)
        else:
            msg = await ctx.send("The server has already been sent.")
            
            await asyncio.sleep(6)
            await msg.delete()
    else:
        embed = discord.Embed(title="Error", description=f"Post command requires 3 arguments.\nUseage: `{get_prefix()}post <link>; <description>; <invites required>`\nto post a server on the nft-projects channel", color=0xF54245)
        msg = await ctx.send(embed=embed)
        await asyncio.sleep(6)
        await msg.delete()

在此之后，嵌入应删除自身并从 JSON 文件中删除自身，但我可以自己执行此操作，我只需要交互帮助来触发 function。

谢谢，里奥

首先，您需要使用 discord.py 版本 2.0.0 才能正常工作。

要将按钮添加到消息中，您首先必须创建一个视图，然后将此视图添加到您要发送的消息中：

class DeleteEmbedView(discord.ui.View):
    @discord.ui.button(label='I joined', style=discord.ButtonStyle.green)
    async def delete(self, button: discord.ui.Button, interaction: discord.Interaction):
        # This is called once the button is clicked
        await interaction.message.delete() #delete the message with the embed
        # delete it from the JSON file here

然后每当您想发送带有消息的按钮时，请执行以下操作：

await channel.send(embed=embed, view=DeleteEmbedView())
