自动清除Discord（discord.js）中发布的最后10张图像 [英] Automatically purge last 10 images posted in Discord (discord.js)

问题描述

我正试图为我的机器人创建一个不和谐的系统，该系统将清除发布的最后10张图片和在聊天中上传（链接和上传），有人知道我该如何编码吗？这是我的主意（

I'm trying to create a system for my bot in discord that'll purge the last 10 images posted & uploaded (links & uploads) in the chat, does anyone know how I can go about coding this? This was my idea (sort of)

if (message.channel.type == 'general') {
    if (*the last 10 messages that have been sent are images*) {
         message.delete(); // delete last 10 images
    }
}

推荐答案

您可以使用 fetchMessages 方法来检索承诺，它由最后10个消息的集合，通过使用limit 设置为10 nofollow noreferrer> ChannelLogsQueryOptions 。

You can use the fetchMessages method to retrieve a promise that consists of a collection of the the last 10 messages, by setting the limit to 10 using the ChannelLogsQueryOptions.

使用此消息集合，就像@Chris Satchell在评论中提到的那样，您可以循环浏览并检查是否 message.attatchments 存在于所有消息中。或者，您可以检查整个邮件集合的附件的< Collection> .size 是否等于10，如果可以，则可以继续下一步。

Using this collection of messages, as @Chris Satchell mentioned in the comments you loop through it and check if message.attatchments is present for all of messages. Alternatively you can check if the <Collection>.size of the attachments for the entire collection of messages is equivalent to 10, and if it does you can go ahead with the next step.

现在，您已经拥有要删除的邮件集合，只需将此集合传递到方法messages 参数rel = nofollow noreferrer> bulkDelete 。

Now that you have a collection of messages that you would like to delete, simply pass this collection into the messages parameter of the method bulkDelete.

因此，您获取了最后一个 TextChannel 中的10条消息，然后检查<$获取的邮件集合的c $ c> attachments 属性，然后在此集合上调用 bulkDelete 方法。

So as a result, you fetch the last 10 messages in a TextChannel, and then check the attachments property of the fetched collection of messages and then call the bulkDelete method on this collection.
