如何在 discord.py 中的命令（例如 User: :send 1234 Bot?1234）后重新发送用户输入？

Question

I have recently started programming my own discord bot as many other people are doing... So far what I have got is this:

@bot.command
async def on_message(message):
   if message.content.startswith("t!send"):
       await client.send_message(message.content)

It doesn't crash but it doesn't work either...

It seems as if you're using a tutorial for an old version of discord.py. There are some big changes in the most recent version - rewrite. Please take some time to look for more updated tutorials, or read the documentation linked above.

Here are the cases for using both the on_message event and commands:

@bot.command()
async def send(ctx, *, sentence):
    await ctx.send(sentence)

######################################

@bot.event
async def on_message(message):
    args = message.content.split(" ")[1:]
    if message.content.startswith("t!send"):
        await message.channel.send(" ".join(args))
    else:
        await bot.process_commands(message) # only add this if you're also using command decorators

• commands.Context() - if not familiar with using command decorators
• discord.on_message()
• Bot.process_commands()

So first of all, on_message doesn't belong here and you also don't have to use it. ( on_message() would use the decorator @bot.event ) Assuming you have setup a prefix for your bot using bot = commands.Bot(command_prefix = 't!') you could do something like this:

@bot.command()
async def send(ctx, *args):
   message = " ".join(args)
   await ctx.send(message)

*args is everything the user types in after t.send: So for example: if the user types in t!send Hello world! args would be ["Hello", "world!"] . With .join we can join them together into a single string ( message )
