(discord.py) 如何在 DM 中显示机器人输入指示器

Question

我听说ctx.typing() 存在，但我希望我的机器人在 DM 中显示指示器。到目前为止，这是我的代码：

@client.event
async def on_message(message):
    await client.process_commands(message)
    # i want the bot to display 'typing...' for 1 second
    if message.guild is None and not message.author.bot:
        with open('dmresponses.txt') as input_file:
            long_list = [line.strip() for line in input_file]
        await message.author.send(random.choice(long_list))

我该如何实现？

Answer 1

这可以通过typing() 上下文管理器来实现：

@client.event
async def on_message(message):
    await client.process_commands(message)
    if message.guild is None and not message.author.bot:
        async with message.channel.typing():
            with open("dmresponses.txt") as input_file: # do stuff inside
                long_list = [line.strip() for lin in input_file]
        await message.author.send(random.choice(long_list)) # what to do after typing

如果你想强调输入持续时间，你可以使用asyncio.sleep()来添加延迟：

import asyncio # required for the sleeping

async with message.channel.typing():
    await asyncio.sleep(0.5)
    # some stuff
await message.channel.send("Done!")
