我正在制作一个音乐机器人，我想在它返回消息时添加一个 Embed，但我收到一个错误，说 const 未定义。

这是我的代码：

const Discord = require('discord.js');
const bot = new Discord.Client({
    partials: ['MESSAGE', 'CHANNEL', 'REACTION']

});
const config = require('./settings.json');
const { loadCommands } = require('./utils/loadCommands');
const DisTube = require('distube');


bot.distube = new DisTube(bot, { searchSongs: false, emitNewSongOnly: true });
bot.distube
    .on("playSong", (message, queue, song) => message.channel.send(
    const exampleEmbed = new Discord.MessageEmbed()   
        .setColor('#0099ff')
    .setTitle('Playing Now:')
    .setDescription('`${song.name}`')
    .setTimestamp()
    .setFooter('Requested by: ${song.user}');        


    .on("addSong", (message, queue, song) => message.channel.send(
        .setColor('#0099ff')
    .setTitle('Added to Queue:')
    .setDescription('\`${song.name}\`')
    .setTimestamp()
    .setFooter('${song.formattedDuration} - Requested by ${song.user}');         

require('./utils/loadEvents')(bot);

bot.commands = new Discord.Collection();
bot.aliases = new Discord.Collection();

loadCommands(bot);

bot.login(config.token);

然后在我运行它之后，我得到了这个错误：

const exampleEmbed = new Discord.MessageEmbed()
    ^^^^^

看起来 channel.send() 接受一个字符串或嵌入作为参数。您应该在发送之前在外部 lambda 中定义消息：

// abbreviated code to relevant snippet
bot.distube = new DisTube(bot, { searchSongs: false, emitNewSongOnly: true });
bot.distube
   .on("playSong", (message, queue, song) => {
       const exampleEmbed = new Discord.MessageEmbed()
           ...
       message.channel.send(exampleEmbed);
   });

我从来没有使用过discord js，但是快速浏览一下文档我猜你应该做一些事情，比如首先声明你的变量然后发送它

bot.distube
    .on("playSong", (message, queue, song) => {
    const exampleEmbed = new Discord.MessageEmbed()
           .setColor('#0099ff')
         .setTitle('Playing Now:')
         .setDescription('`${song.name}`')
         .setTimestamp()
         .setFooter(`Requested by: ${song.user}`);  

     message.channel.send(exampleEmbed);
}

还有2个问题。

  1. 注意.setFooter('Requested by: ${song.user}')模板字符串应该带有反引号 ' ' 。见下文
.setFooter(`Requested by: ${song.user}`)
  1. 您的事件侦听器（ playSong 和 addSong ）和您的send方法似乎没有“关闭”关闭)

在这里阅读更多 ->嵌入不和谐
