Discord.py彩票命令问题：单次购多张票无法发送多Embed

问题背景 #

我正在开发Discord机器人的彩票命令，希望支持用户单次购买多张彩票，但Discord不允许斜杠命令单次发送多个Embed。尝试将游戏逻辑放入for _ in range(amount):循环后无反应，使用await interaction.followup.send(embed=lottery)时出现"The application did not respond"错误。

原代码如下：

@bot.tree.command(name="lottery", description="Every 1 in 100 lottery wins 1,000,000 chips. Lottery costs 10,000 chips.")
@app_commands.describe(amount="Enter the amount of lotteries you'd like to get (max. is set to 5).")
async def lottery(interaction: discord.Interaction, amount:int=1):

    member = interaction.user 


    #Errors
    db = sqlite3.connect("main.sqlite")
    cursor = db.cursor()
    cursor.execute(f"SELECT wallet FROM main WHERE user_id = {member.id}")
    wallet = cursor.fetchone()

    try:
        wallet = wallet[0]
    except:
        wallet = wallet
    
    if amount > 5:
        error2=discord.Embed(description="**ERROR:** You can't buy more than 5 lotteries per command!", color=discord.Color.red())
        return await interaction.response.send_message(embed=error2)
    
    if wallet < 10000*amount:
        error2=discord.Embed(description="**ERROR:** You don't have enough <:chip:1167488856203984957> to play lottery!", color=discord.Color.red())
        return await interaction.response.send_message(embed=error2)
    

    #Game Logic
    winnumber = 55
    win = 1000000
    formatted_win = "{:,}".format(win) #Format win with commas
    formatted_new_balance = "{:,}".format(wallet + win) #Format wallet + payout with commas
    formatted_new_balance2 = "{:,}".format(wallet - 10000) #Format wallet + payout with commas

    botchoice = random.randint(1,101)

    if wallet >= 10000:
        cursor.execute("UPDATE main SET wallet = ? WHERE user_id = ?", (wallet - 10000, member.id))
        db.commit()

        if botchoice == winnumber:
            cursor.execute("UPDATE main SET wallet = ? WHERE user_id = ?", (wallet + win, member.id))
            db.commit()

            lottery = discord.Embed(description=f"You're insane, you just won **{formatted_win}** <:chip:1167488856203984957>\nNew balance: **{formatted_new_balance}** <:chip:1167488856203984957>", color=discord.Color.green())
            lottery.set_author(name=f"{member.name}'s Lottery 🍀", icon_url = member.avatar)
            lottery.set_thumbnail(url="url")
            await interaction.response.send_message(embed=lottery)
        else:
            lottery = discord.Embed(description=f"Sadly you just lost **10,000** <:chip:1167488856203984957>\nNew balance: **{formatted_new_balance2}** <:chip:1167488856203984957>", color=discord.Color.red())
            lottery.set_author(name=f"{member.name}'s Lottery 🍀", icon_url = member.avatar)
            lottery.set_thumbnail(url="url")
            await interaction.response.send_message(embed=lottery)
        
    cursor.close()
    db.close()

核心问题分析 #

1. 响应超时：Discord要求斜杠命令必须在3秒内返回初始响应，直接调用followup.send而未先发送初始响应会触发"应用未响应"错误。
2. 逻辑变量错误：原代码的金额计算、钱包更新均基于初始值，循环时未实时更新钱包状态，且重复执行数据库操作效率低下。

优化解决方案 #

方案1：将所有结果整合到单个Embed（推荐） #

把多次抽奖的结果汇总到一个Embed中，既符合Discord的限制，也能让用户直观看到所有抽奖情况：

import discord
from discord import app_commands
import sqlite3
import random

@bot.tree.command(name="lottery", description="每100张彩票有1张中1,000,000筹码，每张彩票花费10,000筹码。")
@app_commands.describe(amount="输入购买彩票的数量（最多5张）。")
async def lottery(interaction: discord.Interaction, amount:int=1):
    member = interaction.user 

    # 数据库连接与初始化
    db = sqlite3.connect("main.sqlite")
    cursor = db.cursor()
    cursor.execute("SELECT wallet FROM main WHERE user_id = ?", (member.id,))
    wallet_result = cursor.fetchone()

    if wallet_result is None:
        cursor.execute("INSERT INTO main (user_id, wallet) VALUES (?, ?)", (member.id, 0))
        db.commit()
        wallet = 0
    else:
        wallet = wallet_result[0]

    # 错误校验
    if amount > 5:
        error_embed = discord.Embed(description="**ERROR:** 一次最多购买5张彩票！", color=discord.Color.red())
        return await interaction.response.send_message(embed=error_embed)
    
    total_cost = 10000 * amount
    if wallet < total_cost:
        error_embed = discord.Embed(description="**ERROR:** 你的<:chip:1167488856203984957>不足，无法购买这么多彩票！", color=discord.Color.red())
        return await interaction.response.send_message(embed=error_embed)
    
    # 一次性扣除所有彩票费用
    cursor.execute("UPDATE main SET wallet = ? WHERE user_id = ?", (wallet - total_cost, member.id))
    db.commit()
    current_wallet = wallet - total_cost

    # 批量处理抽奖逻辑
    win_number = 55
    win_reward = 1000000
    win_count = 0
    result_list = []

    for idx in range(amount):
        bot_choice = random.randint(1, 101)
        if bot_choice == win_number:
            win_count += 1
            current_wallet += win_reward
            result_list.append(f"第{idx+1}张：🎉 恭喜中奖！获得**{win_reward:,}** <:chip:1167488856203984957>")
        else:
            result_list.append(f"第{idx+1}张：😢 未中奖，扣除**10,000** <:chip:1167488856203984957>")
    
    # 更新最终钱包余额
    cursor.execute("UPDATE main SET wallet = ? WHERE user_id = ?", (current_wallet, member.id))
    db.commit()

    # 生成汇总Embed
    embed_color = discord.Color.green() if win_count > 0 else discord.Color.red()
    lottery_embed = discord.Embed(
        title=f"{member.name}的彩票结果 🍀（中奖{win_count}次）",
        color=embed_color
    )
    lottery_embed.set_author(
        name=member.name,
        icon_url=member.avatar.url if member.avatar else member.default_avatar.url
    )
    lottery_embed.add_field(name="抽奖详情", value="\n".join(result_list), inline=False)
    lottery_embed.add_field(name="最终余额", value=f"**{current_wallet:,}** <:chip:1167488856203984957>", inline=False)
    lottery_embed.set_thumbnail(url="你的缩略图URL")

    # 发送初始响应（必选，避免超时）
    await interaction.response.send_message(embed=lottery_embed)

    cursor.close()
    db.close()

方案2：先发送初始响应再用followup发送结果 #

如果需要分开展示每一张彩票的结果，必须先发送初始响应，再通过followup发送后续消息：

# 关键代码片段
await interaction.response.send_message("正在处理你的彩票请求...")

# 循环处理每张彩票
for idx in range(amount):
    # 单张彩票逻辑处理（省略重复代码）
    single_embed = discord.Embed(...)
    await interaction.followup.send(embed=single_embed)
