問題描述

我正在發出等待用戶回復機器人的命令，但我希望機器人只接受作者的回復.

I am making a command which waits for a user to reply to the bot, but I would like the bot to only accept the author's reply.

@client.command(name='numgame',
            brief='Guess a number between 1 and 100',
            pass_context=True)
async def numgame(context):
number = random.randint(1,100)
guess = 4
while guess != 0:
    await context.send('Pick a number between 1 and 100')
    msg = await client.wait_for('message', check=check, timeout=30)
    attempt = int(msg.content)
    if attempt > number:
        await context.send(str(guess) + ' guesses left...')
        await asyncio.sleep(1)
        await context.send('Try going lower')
        await asyncio.sleep(1)
        guess -= 1
    elif attempt < number:
        await context.send(str(guess) + ' guesses left...')
        await asyncio.sleep(1)
        await context.send('Try going higher')
        await asyncio.sleep(1)
        guess -=1
    elif attempt == number:
        await context.send('You guessed it! Good job!')
        break

我的問題是任何人都可以響應選擇一個數字"，而我只希望啟動命令的人能夠響應.

My issue is that anyone can respond to "Pick a number," whereas I would only like the person who started the command to be able to respond.

我不太確定該嘗試什么，但我認為這可能與爭論有關.不過，我不知道從哪里開始，所以一個解決方案將不勝感激！非常感謝.

I am not too sure what to try, but I think it may have something to do with arguments. I have no idea where to begin, though, so a solution would be appreciated! Thanks a ton.

推薦答案

你需要重寫你的 check 讓它知道作者是誰.一種方法是使用閉包.假設您有一張現有的支票

You need rewrite your check so that it knows who the author is. One way of doing this is to use a closure. Let's say you have an existing check

def check(message):
    return message.content == "Hello"

您可以將其替換為生成等效檢查函數的函數，并將您要檢查的作者注入其中

You can replace this with a function that generates equivalent check functions with the author you want to check for injected into them

def check(author):
    def inner_check(message):
        return message.author == author and message.content == "Hello"
    return inner_check

然后，您可以通過使用適當的參數調用外部檢查，將內部檢查傳遞給 wait_for:

Then you would pass the inner check to wait_for by calling the outer check with the appropriate argument:

msg = await client.wait_for('message', check=check(context.author), timeout=30)

為了您的檢查，這將是

def check(author):
    def inner_check(message): 
        if message.author != author:
            return False
        try: 
            int(message.content) 
            return True 
        except ValueError: 
            return False
    return inner_check
