如何讓我的不和諧機器人響應正確答案？

Question

我正在編寫一個機器人，它在我的不和諧頻道中詢問一個瑣事問題。 我已經重寫了幾次，但無法讓它接受答案。 我可能錯過了一些可怕的東西。

我的代碼：

# bot.py
import os
import json
import discord
from discord.ext import commands
import requests

token=('*removed*')
bot = commands.Bot(command_prefix ='??')
os.chdir(r'C:\Users\thund\OneDrive\Documenten\Python programmeren\Discord - bot')
correct_answer = ''

@bot.event
async def on_ready():
    print(f'{bot.user} has connected to Discord!')

@bot.event
async def on_member_join(member):

    with open('users.json', 'r') as f:
            users = json.load(f)
    await update_data(users, member)

    with open('users.json', 'w') as f:
            json.dump(users, f)

    await member.create_dm()
    await member.dm_channel.send(
        f'Hello {member.name}, You have joined a Discord server where the Mr. Questionnaire is active!\n')
    await member.dm_channel.send(
        f'By default you will get questions which you can answer by preceding your answer by ??')
    await member.dm_channel.send(
        f'There are different prices you can win, try answering some questions and find out!')

@bot.command()       
async def start(ctx):
    global correct_answer
    explanation = (
            'So you want to play a game? We will ask questions, the first one to answer wins one point\n'
            'I will keep firing questions, untill someone types ??stopplease'
            )
    await ctx.send(explanation)
    r = requests.get (url = 'https://opentdb.com/api.php?amount=1')
    data = r.json()
    category = data['results'][0]['category']
    difficulty = data['results'][0]['difficulty']
    question = data['results'][0]['question']
    answer = data['results'][0]['correct_answer']
    correct_answer = answer.replace(' ','_')
    await ctx.send('Category: %s\nDifficulty: %s\nQuestion: %s\n'
                    % (category, difficulty, question))

@bot.command()
async def correct(ctx):
    global correct_answer
    with open('users.json', 'r') as f:
        users = json.load(f)       
    await update_data(users, ctx.author)
    await add_experience(users, ctx.author, 10)
    await level_up(users, ctx.author, ctx.channel)
    with open('users.json', 'w') as f:
       json.dump(users, f)
    await ctx.send('{} has guessed correctly!'.format(ctx.author))
    bot.command('start')

async def update_data(users, user):
    if not user.id in users:
        users[user.id] = {}
        users[user.id]['experience'] = 0
        users[user.id]['level'] = 1

async def add_experience(users, user, exp):
    users[user.id]['experience'] += exp

async def level_up(users, user, channel):
    experience = users[user.id]['experience']
    lvl_start = users[user.id]['level']
    lvl_end = int(experience ** (1/4))

    if lvl_start < lvl_end:
        await ctx.send(channel, '{} has leveled up to level {}'.format(user.mention, lvl_end))
        users[user.id]['level'] = lvl_end

@bot.command(name='supersecret')
async def answer(ctx):
    global correct_answer
    await ctx.send('The Answer is: %s' % (correct_answer))

@bot.command(name='%s' % (correct_answer))
async def correct22(ctx):
        global correct_answer
        with open('users.json', 'r') as f:
            users = json.load(f)       
        await update_data(users, message.author)
        await add_experience(users, message.author, 10)
        await level_up(users, message.author, message.channel)
        with open('users.json', 'w') as f:
            json.dump(users, f)
        await ctx.send('{message.author} has guessed correctly!')

async def update_data(users, user):
    if not user.id in users:
        users[user.id] = {}
        users[user.id]['experience'] = 0
        users[user.id]['level'] = 1

async def add_experience(users, user, exp):
    users[user.id]['experience'] += exp

async def level_up(users, user, channel):
    experience = users[user.id]['experience']
    lvl_start = users[user.id]['level']
    lvl_end = int(experience ** (1/4))

    if lvl_start < lvl_end:
        await bot.send_message(channel, '{} has leveled up to level {}'.format(user.mention, lvl_end))
        users[user.id]['level'] = lvl_end

@bot.command(name='stopplease', help='Stop it right now!')
async def stop_quiz(ctx):
    await ctx.send('Thank you for playing our game!\n'
                   'If you like it, please consider a donation and/or using it on all the servers you know!')

@bot.event
async def on_error(event, *args, **kwargs):
    with open('err.log', 'a') as f:
        if event == 'on_message':
            f.write(f'Unhandled message: {args[0]}\n')
        elif event == 'command':
            f.write(f'Unhandled command: {args[0]}\n')
        else:
            raise
bot.run(token)

我嘗試添加一些我希望它可以觸發的命令，但我完全遺漏了一些東西。

謝謝您的幫助！

Answer 1

你的問題是對裝飾者的誤解。 它們是一個相當復雜的話題，所以這里有一個基本資源。 對您來說，最重要的是以下幾點：裝飾器只運行一次，這意味着只要您運行文件，它就會監聽其中的任何內容。 現在你想在你的代碼中做什么

@bot.command(name='%s' % (correct_answer))

是在裝飾器中有一個動態值，所以機器人會響應正確的答案。 這不起作用！ 裝飾器只運行一次。

那么我們如何解決這個問題呢？ 我們需要稍微重寫你的正確 22 函數。 您的機器人可以通過arguments處理動態輸入。 幸運的是，這些在 bot 擴展中很容易做到。 即使有參數，我們仍然需要一個命令名稱，所以讓我們選擇“answer”。 因此，在您嘗試回答??2005您現在回答??answer 2005 。 您可以嘗試按照最初的意圖進行操作，但在我看來，這會使您的代碼過於復雜，因為您必須處理消息處理程序。

潛在的解決方案：

@bot.command(name='answer')
async def correct22(ctx, answer):
        global correct_answer
        if correct_answer != answer:
            return
        with open('users.json', 'r') as f:
            users = json.load(f)       
        await update_data(users, message.author)
        await add_experience(users, message.author, 10)
        await level_up(users, message.author, message.channel)
        with open('users.json', 'w') as f:
            json.dump(users, f)
        await ctx.send('{message.author} has guessed correctly!')

我還沒有測試過像體驗這樣的用戶功能，但至少消息回復應該像這樣工作。
