How to get how many messages has been sent in a channel

问题

I am trying to get the number of how many messages have been sent in a channel, and using the logs_from() function wont work because that only accepts a fixed amount of messages to retrieve, how do I do this?

回答1:

In the discord.py-rewrite branch, there is a TextChannel.history AsyncIterator. If you pass limit=None, it will return all the messages from the channel

@bot.command()
async def message_count(ctx, channel: discord.TextChannel=None):
    channel = channel or ctx.channel
    count = 0
    async for _ in channel.history(limit=None):
        count += 1
    await ctx.send("There were {} messages in {}".format(count, channel.mention))

You might try passing limit=None to logs_from, but it isn't documented as working that way like it is in the rewrite branch.
