Question

我试图让机器人在特定时间段内发送消息时告诉用户上床睡觉，但仅让机器人每x分钟做出反应。这是通过检查当前消息和最后一条消息之间的时间差是否大于x来完成的。目前输出的内容完全没有，甚至没有错误。

我设法通过以下方式在“正常”的python中获得了与预期结果相同的结果：

import datetime
import json
now = datetime.datetime.now()
nowHourMin = float( now.hour ) + ( float( now.minute )/60 )   

def get_time():
    filename = "messageRecord.json"
    try:                                 #If file exists, get time of last message
        with open(filename, "r") as f:
            lastMessage = json.load(f)
    except FileNotFoundError:            #If file doesn't exists, create it and store current time
        lastMessage = nowHourMin
        with open(filename, "w") as f:
            json.dump(lastMessage, f)
    return lastMessage

def update_time():                       #Store current time
    filename = "messageRecord.json"
    with open(filename, "w") as f:
        json.dump(nowHourMin, f)           
    
def message_responder():
    lastMessage = get_time()
    dt = nowHourMin - lastMessage
    if (nowHourMin < 23 ) and (dt >0.01):
        print("Please go to bed, it is getting late")
    update_time()

message_responder()

但是当我尝试使代码适应不和谐的库时，我没有得到任何结果。不会创建json文件，当我自己创建一个json文件时，不会写入任何文件。它也没有任何错误，只是什么也没有。其他命令和事件也可以正常工作。这是discord.py版本：

import discord
import json
import datetime
from discord.ext import commands, tasks

now = datetime.datetime.now()
nowHourMin = float( now.hour ) + ( float( now.minute )/60 )

async def get_time():
    filename = "messageRecord.json"
    try:                                #If file exists, get time of last message
        with open(filename, "r") as f:
            lastMessage = json.load(f)
    except FileNotFoundError:           #If file doesn't exists, create it and store current time
        lastMessage = nowHourMin
        with open(filename, "w") as f:
            json.dump(lastMessage, f)
    return lastMessage

async def update_time():
    filename = "messageRecord.json"
    with open(filename, "w") as f:
        json.dump(nowHourMin, f)                       

def message_responder(message):
    lastMessage = get_time()                            #Get time of last message from "messageRecord.json"
    dt = nowHourMin - lastMessage                       #Time difference
    if (message.author != client.user) and (nowHourMin < 23 ) and (dt >0.01):   #Values will be adjusted once bot works
        await message.channel.send("Please go to bed, it is getting late")
    else:
        await message.channel.send("Dummy text")        #Will be removed once code works, just to confirm bot is working.
    await update_time()                                 #Updates lastMessage to now

@client.event
async def on_message(message):
    await message_responder(message)
    await client.process_commands(message)              #Prevents on_message()from overwriting commands

您需要等待get_time()，因为它是一个异步函数。您还需要使message_responder()异步：

async def message_responder(message): #<- here
    lastMessage = await get_time() #<- and here
    dt = nowHourMin - lastMessage
    if (message.author != client.user) and (nowHourMin < 23 ) and (dt >0.01):
        await message.channel.send("Please go to bed, it is getting late")
    else:
        await message.channel.send("Dummy text")
    await update_time()

on_message（）事件仅每x分钟通过存储时间做出反应
