discord.py - 多条消息发布 - RuntimeError：事件循环已关闭

Question

我想创建一个 Discord 机器人，它将我在控制台中输入的消息或使用另一段代码（例如传感器数据）生成的消息发送到通道。 我已经尝试过以下操作，但在输入第二条消息后，我得到了 RuntimeError: Event loop is closed。有什么建议吗？

import discord


def send_message(message):
    token = "mydiscordbottoken"
    channel_id = channelid
    bot = discord.Client()

    @bot.event
    async def on_ready():
        await bot.get_channel(channel_id).send(message)
        await bot.close()

    bot.run(token)


while True:
    mes = input('Enter message: ')
    send_message(mes)

我想在打印消息后回到我的 while 循环外的功能。 运行代码时出现以下错误：

我对 asycio 和 discord.py 有点陌生，只是想将多条消息打印到我的 discord 服务器。 提前谢谢！

Answer 1

您没有正确设置代码，input() 将冻结代码。这是我建议您这样做的方法。

import discord
from discord.ext import commands

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

@client.command()
async def sendMessage(ctx, channel: discord.TextChannel, *, message):
    await channel.send(message)

client.run("TOKEN")

这样你就可以执行命令(PREFIX)sendMessage (#CHANNEL) (MESSAGE)。由于您是新手，我还将解释命令参数中* 的用法。 * 允许我们的消息长度为多个单词，以便频道之后的任何内容都包含在消息中。

如果您还有任何问题，请随时在 StackOverflow 或 Discord 上的 starmoan#4269 上给我发消息！
