安排Asyncio任务每X秒执行一次？ [英] Schedule Asyncio task to execute every X seconds?

问题描述

我正在尝试创建一个python discord机器人，该机器人将每隔X秒检查一次活跃成员，并为他们的在线时间奖励积分。我正在使用asyncio处理聊天命令，并且一切正常。我的问题是找到一种方法来安排使用异步每隔X秒对活动成员进行一次检查

I'm trying to create a python discord bot that will check active members every X seconds, and award members with points for their time online. I'm using asyncio to handle the chat commands and that is all working. My issue is finding a way to schedule this checking of active members every X seconds with async

我已经阅读了asnycio文档，但这是我第一次使用它，并且我很难把头放在任务，循环和协同例程等上。

I've read the asnycio documentation but this is my first time working with it and I'm having a hard time wrapping my head around tasks and loops and co routines and etc.

@client.event
async def on_message(message):

    # !gamble command
    if message.content.startswith('!gamble'):

        ...code that works....

    # !help command
    elif message.content == '!help':

         ...code that works....

    # !balance command
    elif message.content == '!balance':

      ...code that works....

@client.event
async def on_ready():
    print('Logged in as')
    print(client.user.name)
    print(client.user.id)
    print('------')

# Do this every X seconds to give online users +1 points
async def periodic_task():
      TODO

我的目标是让机器人能够处理通过聊天发送给它的命令，同时每X秒触发一次与Discord服务器中的聊天命令或事件无关的功能。我知道如何使函数中的代码实现我的目标，而不是如何触发

My goal is to have the bot be able to handle commands given to it through chat, while also triggering a function every X seconds unrelated to chat commands or events in the Discord server. I know how to make the code inside the function achieve my goal, just not how to trigger it

推荐答案

async def do_stuff_every_x_seconds(timeout, stuff):
    while True:
        await asyncio.sleep(timeout)
        await stuff()

并将其添加到循环中。

task = asyncio.create_task(do_stuff_every_x_seconds(10, stuff))

当您不再想要这样做时，

When you no longer want to do that,

task.cancel()
