Get message content from reply in DM

问题

I started making a little discord bot to give a key to people who request it. However, requirements changed and now I need to get a valid email from people who want one. I'm not sure how to get a reply in a DM.

I saw Discord.py get message from DM

But I don't really have client.get_user_info() or something?

bot = commands.Bot(command_prefix='!')


@bot.command(pass_context =True, no_pm=True, name='key', help="I give you a key. you're welcome", )



async def key_giver(ctx):
    commandTime = str(datetime.now().strftime('%Y-%m-%d %H:%M:%S'))


##check if you're PMing bot
    elif isinstance (ctx.channel, discord.DMChannel):
        print(ctx.message)
        await ctx.author.send(keyArray[0])

    else:
        response = "Hello my friend. I give you a key for a game. This is my purpose. Please enter your email!"



    ##Send key via PM 
    await ctx.author.send(response)

Printing ctx.message is

<Message id=620538695124254720 channel=<DMChannel id=614377525417738240 recipient=<User id=605223566371192852 name='aon' discriminator='5906' bot=False>> type=<MessageType.default: 0> author=<User id=605223566371192852 name='aon' discriminator='5906' bot=False>>

I'm really not sure. I'm just stupid, please don't yell at me.

You can use Client.wait_for to wait for the message and use its results. You already have the User object (ctx.author), so you can get the channel to listen for from User.dm_channel. I'm re-using the message_check function from this previous answer to generate the check

# Send them a message in a DM
await ctx.author.send("Please give an email address")

# Wait for a response
response = await bot.wait_for('message', check=message_check(channel=ctx.author.dm_channel))
