Discord Py 将消息发送到特定通道

Question

I'm working on my discord bot. I'm making an order to send a message to a specific room except I can't make it... Here's my code:

@client.command(name='say', help='Dire un message à votre place')
@commands.has_permissions(send_messages=True, manage_messages=True)
async def say(ctx, message, channelid):
    await client.wait_until_ready()
    channel = client.get_channel(channelid)
    embed = discord.Embed(title="Message", color=discord.Color.dark_red())
    embed.add_field(name="Nouveau message de {}".format(ctx.message.author), value="{}".format(message))
    embed.set_footer(text="{}".format(ctx.message.author))
    await channel.send(embed=embed)

and here's the error I'm getting in the terminal.

Command raised an exception: AttributeError: 'NoneType' object has no attribute 'send"

Thank you in advance for your response.

PS: My bot is in french

You can have a message as string more then one word, by doing:

@client.command(name='say', help='Dire un message à votre place')
@commands.has_permissions(send_messages=True, manage_messages=True)
async def say(ctx, channel:discord.TextChannel, message):
    #Embed making
    embed = discord.Embed(title="Message", color=discord.Color.dark_red())
    embed.add_field(name="Nouveau message de {}".format(ctx.message.author), value="{}".format(message))
    embed.set_footer(text="{}".format(ctx.message.author))

    await channel.send(embed=e)

The colon and discord.Channel signifies you need to enter an #channel format on discord screen Also to have a multi letter message, do this:

async def say(ctx, channel:discord.TextChannel, *msg):
    message = " ".join(msg)
    #Embed making
    embed = discord.Embed(title="Message", color=discord.Color.dark_red())
    embed.add_field(name="Nouveau message de {}".format(ctx.message.author), value="{}".format(message))
    embed.set_footer(text="{}".format(ctx.message.author))

    await channel.send(embed=e)

the star sign makes it a tuple, So if you do

c?say #text-channel-send Hello and Bye

So Hello, and, bye are parts of a tuple, like this: ('Hello','and','bye') so when you do

" ".join(msg)

it joins the elements of tuple to give you a string, separeted by spaces. It works for lists too. Hope this helps

Here is part of a code that can get you started: I have recently made this:

@client.event
async def on_member_join(member):
    channel = discord.utils.get(member.guild.channels, name="👋│arrivals")
    await channel.send(f"Welcome to Sleep's Gaming Cult {member.mention}! You are the ### member")

You can than change name to id and put your channel id instead of "│arrivals"! I have not test this out but this my best guess that it will work! Of course this is an example for when someone joins but you can use this for any command!
