如何让不和谐机器人阅读嵌入

2022-01-10 00:00:00 discord javascript discord.js

我了解不和谐机器人如何读取常规用户输入的消息并使用

I understand how a discord bot can read a regular user inputed message and respond using 

if(message.content.toLowerCase().includes('cyber'))
    message.channel.send("Key Word Detected ");

但如果它是嵌入的，它不会读取消息.请帮我更改它以在嵌入消息中查找关键字并引起机器人的响应.

But it won't read the message if it is an embed. Please help me change that to look for the keyword in a embed message and elicit a response from the bot.

推荐答案

MessageEmbed 可以在 author, description, footer, message.content 和 title.它们也可以在每个文件中，因此可能需要检查所有这些内容.
这是你可以使用的一个小函数(我知道这看起来很乱，但这只是因为有很多逻辑运算符):

The text in a MessageEmbed can be in author, description, footer, message.content and title. They can also be inside every filed, so might want to check for all that stuff.
Here's a little function you could use (I know it seems a mess but it's just because there are a lot of logical operators): 

/*
      message {Discord.Message}: the message you want to search in
      target {string}: the string you're looking for
      {
        caseSensitive {boolean}: whether you want the search to be case case-sensitive
        author {boolean}: whether you want to search in the author's name
        description {boolean}: whether you want to search in the description
        footer {boolean}: whether you want to search in the footer
        title {boolean}: whether you want to search in the title
        fields {boolean}: whether you want to search in the fields
      }
     */
function findInMessage(message, target, {
  caseSensitive = false,
  author = false,
  description = true,
  footer = true,
  title = true,
  fields = true
}) {
  if (!target || !message) return null;
  let str = caseSensitive ? target : target.toLowerCase();

  if ((caseSensitive && message.content.includes(str)) ||
    (!caseSensitive && message.content.toLowerCase().includes(str))) return true;

  for (let embed of message.embeds) {
    if ((caseSensitive && (
        (author && embed.author.includes(str)) ||
        (description && embed.description.includes(str)) ||
        (footer && embed.footer.includes(str)) ||
        (title && embed.title.includes(str)))) ||
      (!caseSensitive && (
        (author && embed.author.toLowerCase().includes(str)) ||
        (description && embed.description.toLowerCase().includes(str)) ||
        (footer && embed.footer.toLowerCase().includes(str)) ||
        (title && embed.title.toLowerCase().includes(str))))
    ) return true;

    if (fields)
      for (let field of embed.fields) {
        if ((caseSensitive && [field.name, field.value].includes(str)) ||
          (!caseSensitive && [field.name.toLowerCase(), field.value.toLowerCase()].includes(str))) return true;
      }
  }

  return false;
}

函数在找到您输入的单词时返回 true，在没有找到时返回 false，在其中之一时返回 null缺少非可选参数.
你可以这样使用它:

The functions returns true when finds the word you put in, false when it doesn't find it and null when one of the non-optional arguments is missing.
You can use it like this:

if (findInMessage(message, 'cyber')) message.channel.send("Key word detected.");
