如何输入提到的通道并在该通道中发送消息？

Question

我有下面的代码从消息生成嵌入，它现在可以正常工作。我想要的是，在创建嵌入后，bot应该要求用户提到一个频道，在用户提到一个频道后，bot应该将该嵌入发送到那里。我该怎么做？

@bot.command()
async def embed(ctx):
    await ctx.send("Enter title for embed:")
    e = await get_input_of_type(str, ctx)
    await ctx.send("Enter the content for embed:")
    c = await get_input_of_type(str, ctx)
    embed = discord.Embed(
        title = e,
        description = c,
        color = 0x03f8fc,
        timestamp= ctx.message.created_at
    )
    embed.set_thumbnail(url = ctx.guild.icon_url)
    await ctx.channel.send(embed=embed)
    

Answer 1

我使用了客户端。wait_for（）coroutine等待来自用户的消息。然后我格式化了消息。content字符串，仅获取频道的ID。然后我用了不和谐。乌提尔斯。get方法仅使用ID获取通道。

# at the top of the file
from discord.utils import get


    @client.command()
    async def embed(ctx):

        # embed stuff here
        
        def check(msg):
            # make sure the author of the message we're waiting for is the same user that invoked the command
            return ctx.author == msg.author
        
        await ctx.send("mention a channel to send to")
        msg = await client.wait_for('message', timeout=60.0, check=check)
        

        msg = msg.content.split("#")[1].split('>')[0]
"""
over here we are spliting the '#' from the message content first and index just the ID with the '>' 
(if the message is just a channel mention it shoud be something like this:  <#000000000000000000>) 
then we split the '>' from the string and index just the ID part and now we have the ID of the channel
"""
        channel = get(ctx.guild.channels, id=int(msg))

        await channel.send(f'{words}')

使用wait_for（）和代码

@bot.command()
async def embed(ctx):
    def check(m):
        return m.author == ctx.author and m.channel == ctx.channel
    await ctx.send("Enter title for embed:")
    e = await get_input_of_type(str, ctx)
    await ctx.send("Enter the content for embed:")
    c = await get_input_of_type(str, ctx)
    embed = discord.Embed(
        title = e,
        description = c,
        color = 0x03f8fc,
        timestamp= ctx.message.created_at
    )
    embed.set_thumbnail(url = ctx.guild.icon_url)
    channel = await bot.wait_for("message", check=check)
    channel = await commands.TextChannelConverter().convert(ctx, channel.content)
    await channel.send(embed=embed)
