bot 执行下一个命令而不等待消息

Question

您好，我一直在尝试为我的服务器创建一个应用程序机器人，该机器人向您发送一个问题，然后该人回答，然后记下等，但我的问题是，有时下一个问题会发送而无需等待前一个问题的答案问题。这只发生在大多数时候。试试我可能无法解决问题。我对 python 还很陌生，而且我也束手无策。 我的参考代码：

import os       
from discord.ext import commands    
from discord.utils import get 
BOT_PREFIX = ("!")
client = commands.Bot(command_prefix=BOT_PREFIX)    
a_list = []   
@client.event
async def on_ready():
    print ("------------------------------------")
    print ("Bot Name: " + client.user.name)
    print ("------------------------------------")        
submit_wait = False
a_list = []
b_list = []
c_list = []
d_list = []      
@client.command(aliases=['application'])
async def app(ctx):
    a_list = []
    b_list = []
    c_list = []
    d_list = []
    submit_wait = False    
    submit_channel = client.get_channel(806404345830047744)
    channel = await ctx.author.create_dm()
    await channel.send("starting applaction!")
    await ctx.send(ctx.author.mention + "check your dms!")
    time.sleep(2)    
    def check(m):
        return m.content is not None and m.channel == channel        
    await channel.send("Do you have any prior milli sim experiance?")
    msg = await client.wait_for('message', check=check)
    a_list.append(msg.content)        
    await channel.send("What time zone are you in?")        
    msg2 = await client.wait_for('message', check=check)
    b_list.append(msg2.content)        
    await channel.send("If a officer ordered you to break the genva convention would you do it?")        
    msg3 = await client.wait_for('message', check=check)
    c_list.append(msg3.content)        
    await channel.send("Is there any particular dvision you want to be in?")    
    msg4 = await client.wait_for('message', check=check)
    d_list.append(msg4.content)       
    await channel.send('thank you for applying! a officer will do your application as soon as they can - respound with "submit" to submit your application')
    msg = await client.wait_for('message', check=check)
    if "submit" in msg.content.lower():
      submit_wait = False
      answers = "\n".join(f'{a}. {b}' for a, b in enumerate(a_list, 1))
      answer = "\n".join(f'{a}. {b}' for a, b in enumerate(b_list, 2))
      answerr = "\n".join(f'{a}. {b}' for a, b in enumerate(c_list, 3))
      answerss = "\n".join(f'{a}. {b}' for a, b in enumerate(d_list, 4))                
      submit_msg = f'Application from {msg.author} \nThe answers are:\n{answers}'
      submit_msg2 = f'{answer}'
      submit_msg3 = f'{answerr}'
      submit_msg4 = f'{answerss}'
      await submit_channel.send(submit_msg)
      await submit_channel.send(submit_msg2)   
      await submit_channel.send(submit_msg3)
      await submit_channel.send(submit_msg4)   
client.run(os.getenv('TOKEN'))

Answer 1

我使用print() 测试了代码，我认为问题在于check() 有时会收到机器人的问题并将其视为用户的答案。

您必须在check() 中检查m.author - 类似这样的内容

@client.command(aliases=['application'])
async def app(ctx):
    submit_channel = client.get_channel(806404345830047744)
    #print('submit_channel:', submit_channel)

    channel = await ctx.author.create_dm()
    author = ctx.author

    def check(m):
        #print('m.author:', m.author)
        #print('m.content:', m.content)
        #print('m.channel:', m.channel, m.channel == channel)
        return m.author == author and m.content and m.channel == channel

---

具有其他更改的最少工作代码

import os
import time
from discord.ext import commands

client = commands.Bot(command_prefix="!")

@client.event
async def on_ready():
    print ("------------------------------------")
    print ("Bot Name:", client.user.name)
    print ("------------------------------------")

@client.command(aliases=['application'])
async def app(ctx):
    submit_channel = client.get_channel(806404345830047744)
    print('submit_channel:', submit_channel)

    channel = await ctx.author.create_dm()
    author = ctx.author

    def check(m):
        print('m.author:', m.author)
        print('m.content:', m.content)
        print('m.channel:', m.channel, m.channel == channel)
        return m.author == author and m.content and m.channel == channel

    await channel.send("starting applaction!")
    await ctx.send(ctx.author.mention + " check your dms!")
    time.sleep(2)

    await channel.send("Do you have any prior milli sim experiance?")
    answer_a = await client.wait_for('message', check=check)
    answer_a = answer_a.content

    await channel.send("What time zone are you in?")
    answer_b = await client.wait_for('message', check=check)
    answer_b = answer_b.content

    await channel.send("If a officer ordered you to break the genva convention would you do it?")
    answer_c = await client.wait_for('message', check=check)
    answer_c = answer_c.content

    await channel.send("Is there any particular dvision you want to be in?")
    answer_d = await client.wait_for('message', check=check)
    answer_d = answer_d.content

    await channel.send('thank you for applying! a officer will do your application as soon as they can - respound with "submit" to submit your application')
    msg = await client.wait_for('message', check=check)

    if "submit" in msg.content.lower():
        submit_msg = f'''Application from {msg.author}
The answers are:
1. {answer_a}
2. {answer_b}
3. {answer_c}
4. {answer_d}'''
        await submit_channel.send(submit_msg)

client.run(os.getenv('TOKEN'))

Answer 2

好吧，乍一看我发现了一些错误

首先，小问题，但使用time.sleep(2) 会暂停整个机器人，因此如果您想让其他人同时运行此命令，您可能需要更改此设置

import asyncio # instead of import time
 
await asyncio.sleep(2) # instead of time.sleep(2)

另外你不需要重复那么多代码，这应该让它完全按照你想要的方式工作

import os       
from discord.ext import commands    
from discord.utils import get
import asyncio

client = commands.Bot(command_prefix="!")    

@client.event
async def on_ready():
    print ("------------------------------------")
    print ("Bot Name: " + client.user.name)
    print ("------------------------------------")

submit_wait = False
questions = ["Do you have any prior milli sim experiance?",
             "What time zone are you in?",
             "If a officer ordered you to break the genva convention would you do it?",
             "Is there any particular dvision you want to be in?"]

@client.command(aliases=['application'])
async def app(ctx):
    
    submit_channel = client.get_channel(810118639234973719)
    channel = await ctx.author.create_dm()
    
    await channel.send("starting applaction!")
    await ctx.send(ctx.author.mention + "check your dms!")
    await asyncio.sleep(2)
    
    def check(m):
        return m.content != "" and m.channel == channel

    answers = []
    for question in questions:
        await channel.send(question)
        msg = await client.wait_for("message", check=check)
        answers.append(msg.content)
    
    await channel.send('thank you for applying! a officer will do your application as soon as they can - respound with "submit" to submit your application')
    msg = await client.wait_for("message", check=check)

    if "submit" in msg.content.lower():
        submit_wait = False
        answers = [f"{no+1}. {ans}" for no, ans in enumerate(answers)]
        submit_msg = [f"Application from {msg.author}",
                      "The answers are:", *answers]
        await submit_channel.send("\n".join(submit_msg))

client.run(os.getenv('TOKEN'))
