如何在没有命令的情况下使用 discord.py 发送消息

How to send a message with discord.py without a command(如何在没有命令的情况下使用 discord.py 发送消息)

问题描述

import discord
import asyncio

client = discord.Client()
@client.event
async def on_ready():
    print("I'm ready.")

async def send(message):
    await client.send_message(client.get_channel("123456789"), message)

client.run("token")

loop = asyncio.get_event_loop()
loop.run_until_complete(send("hello"))

我想做一个 GUI.当有人输入他的名字并按确定"时我的不和谐机器人应该发送一条消息.基本上我以为我用它的名字来称呼异步，没有用.然后我做了一个事件循环.使用 print()，但机器人没有发送消息，所以我认为它还没有准备好，当我把 wait_until_ready() 放在那里它什么也没执行，所以我认为我必须把 client.run("token") 在事件循环之前也不起作用.

Hi, i want to make a GUI. When someone put in his name and press "OK" my discord bot should send a message. Basically i thought i call the async by it's name, didn't work. Then i made a event loop. worked with a print(), but the bot doesn't send a message, so i thought it is not ready, when i put wait_until_ready() there it executed nothing, so i thought i have to put the client.run("token") before the event loop, didn't work either.

你们能帮帮我吗?:)

推荐答案

你的代码不工作的原因是因为 client.run 是阻塞的，这意味着它之后什么都不会执行.这意味着你的 loop 永远不会到达.

The reason your code is not working is because client.run is blocking, meaning that nothing after it will execute. This means your loop will never be reached.

要解决这个问题，请使用 client.loop.create_task.

To get around this, use client.loop.create_task.

discord.py的github有后台任务的例子，找到这里.您应该可以将其用作参考.目前该任务每分钟向给定频道发布一条消息，但您可以轻松修改它以等待特定操作.

The github of discord.py has an example of a background task, found here. You should be able to use this as reference. Currently the task posts a message to the given channel every minute, but you can easily modify it to wait for a specific action.

新的 discord.py 版本

New discord.py versions

import discord
import asyncio

client = discord.Client()

async def my_background_task():
    await client.wait_until_ready()
    counter = 0
    channel = client.get_channel(id=123456789) # replace with channel_id
    while not client.is_closed():
        counter += 1
        await channel.send(counter)
        await asyncio.sleep(60) # task runs every 60 seconds

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

client.loop.create_task(my_background_task())
client.run('token')

较旧的 discord.py 版本

Older discord.py versions

import discord
import asyncio

client = discord.Client()

async def my_background_task():
    await client.wait_until_ready()
    counter = 0
    channel = discord.Object(id='channel_id_here')
    while not client.is_closed:
        counter += 1
        await client.send_message(channel, counter)
        await asyncio.sleep(60) # task runs every 60 seconds

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

client.loop.create_task(my_background_task())
client.run('token')
