I want to know how to get a message content (specifically the embeds) from the message id? Just like you can get the member using a member id

回答1:

`on_raw_reaction_add()` example:

@bot.event
async def on_raw_reaction_add(payload):
    channel = bot.get_channel(payload.channel_id)
    msg = await channel.fetch_message(payload.message_id)
    embed = msg.embeds[0]
    # do something you want to

Command example:

@bot.command()
async def getmsg(ctx, channel: discord.TextChannel, msgID: int):
    msg = await channel.fetch_message(msgID)
    await ctx.send(msg.embeds[0].description)

In the command I'm passing in channel and msgID, so a sample command execution would like !getmsg #general 112233445566778899 - the channel must be in the same server that you're executing the command in!

Then I'm getting the message object using the fetch_message() coroutine, which allows me to get a list of embeds in said message. I then choose the first, and only, embed by choosing position index 0.

After that, the bot then sends the description (or whatever attribute you'd like) of the embed.

References:

discord.TextChannel
TextChannel.fetch_message()
Message.embeds
discord.Embed - This is where you can find the different attributes of the embed
commands.command() - Command decorator
on_raw_reaction_add()
discord.RawReactionActionEvent - The payload returned from the reaction event
RawReactionActionEvent.message_id - The ID of the message which was reacted to
RawReactionActionEvent.channel_id - The text channel that the reaction was added in
