javascript - Discord.js embedMsg 未定义？

Question

您好，我正在尝试制作一个不和谐的机器人，一旦您单击添加到其嵌入消息中的 react ，它就会根据您单击的内容响应一条消息，一个表示是，一个表示否。

一切看起来都很好，但是当我运行命令时，我得到 const Collector = embedMsg.messageembedMsg 未定义。我已经尝试了一切，所以我很感谢我能得到的任何类型的帮助

这是我的代码:

const {Client, RichEmbed} = require('discord.js');
const client = new Client();
client.once('ready', () => {
   console.log('dance time');

client.on('message', message => {
if(message.author.bot)
{
if(message.embeds)
{
   const embedMsg= message.embed.find(msg => msg.title === 'Boogie Time!?');
   if(embedMsg)
   {
       embedMsg.message.react('✅')
       .then(reaction => reaction.message.react('❌'))

       .catch(error => console.error);
   }
}
return;

}
   // Do this after you've added reactions

// This is filter, this specified which reactions it should capture, you can use filter to make sure you're only catching specific reactions by specific user
const filter = (reaction, user) => (reaction.emoji.name === '✅' || reaction.emoji.name === '❌') && user.id === message.author.id;

// Here, we're defining a collector that will be active for 30 seconds and collect reactions that pass the above filter
const collector = embedMsg.message.createReactionCollector(filter, {time: 30000});

// This event is emitted when a reaction passes through the filter
collector.on('collect', r => r.name === '✅' ? console.log('Reacted Yes') : console.log('Reacted No'));

if(message.content.toLowCase() === 'boogie')
{
   const embed = new RichEmbed();
   embed.setTitle("Boogie Time!?")
   embed.setColor("GREEN")
   embed.setDescription("Are you sure?")
   message.channel.send(embed);
}
})
});

代码中的第一个问题是 client.on('ready' ) 阻止您在 client.on('message' block 之后结束他。正确的方法是:

client.on('ready', () => {
   console.log('dance time');
})

message.embeds 它的集合数组，所以需要使用

const embedMsg = message.embeds.find(msg => msg.title === 'Boogie Time!?');

为了获得代码的最佳可读性，尽量不要使用 if(somethink) then do somethink更好的方式是 if(!somethink) return;

这将使您摆脱大量括号。在您的代码中，您尝试等待 react ，无论此消息是否嵌入。并且在使用 return 添加 react 后停止函数，因此收集器将永远无法工作。

当您 const 收集器时，您不需要 embedMSG.message 因为 find 方法已经返回一条消息。

所以你的代码必须是这样的

    const {Client, RichEmbed} = require('discord.js');
    const client = new Client();
    client.once('ready', () => {
       console.log('dance time');
    })
    client.on('message', message => {

      if(!message.author.bot || !message.embeds) return
      const embedMsg = message.embeds.find(embed => embed.title === 'Boogie Time!?');
      if(!embedMsg) return

      embedMsg.react('🍎')
            .then(() => message.react('🍊'))
            .catch(() => console.error('One of the emojis failed to react.'));

    // This is filter, this specified which reactions it should capture, you can use filter to make sure you're only catching specific reactions by specific user
    const filter = (reaction, user) => (reaction.emoji.name === '?' || reaction.emoji.name === '?') && user.id === message.author.id;

    // Here, we're defining a collector that will be active for 30 seconds and collect reactions that pass the above filter

    // This event is emitted when a reaction passes through the filter
    collector.on('collect', r => r.name === '?' ? console.log('Reacted Yes') : console.log('Reacted No'));

      if(message.content.toLowCase() === 'boogie'){
         const embed = new RichEmbed();
         embed.setTitle("Boogie Time!?")
         embed.setColor("GREEN")
         embed.setDescription("Are you sure?")
         message.channel.send(embed);
      }
  })
