Discord.js：MessageAttachment 未定义

discord.js

我无法让我的机器人过滤消息并使用计算机中的本地文件进行响应。代码如下：

client.on("message", msg => {
      console.log(msg.content);
      let wordArray = msg.content.split(" ")
      console.log(wordArray)

      let filterWords = ['test']

      for(var i = 0; i < filterWords.length; i++) {
        if(wordArray.includes(filterWords[i])) {
          msg.delete()
          // Create the attachment using MessageAttachment
          const attachment = new MessageAttachment('cbcfilter.png');
          msg.channel.send(attachment)  
        }
      }
    });

它给出了此错误消息：

    ReferenceError: MessageAttachment is not defined

        at Client.emit (events.js:323:22)

        at Receiver.receiverOnMessage (/Users/DShirriff/cbcbot/node_modules/ws/lib/websocket.js:801:20)

我是不是太笨了，漏掉了一个简单的括号，还是我应该寻找此行代码的其他形式？

Answer 1

您需要导入 MessageAttachment 。

如果您使用 require 导入 discord.js，那么您可以执行以下操作：

const Discord = require('discord.js')
const attachment = new Discord.MessageAttachment('cbcfilter.png');

如果您使用 import ，那么您可以执行以下操作：

import { MessageAttachment } from 'discord.js'
const attachment = new MessageAttachment('cbcfilter.png');

附注：您不必构建 MessageAttachment ，您只需执行

msg.channel.send({files: ['cbcfilter.png']})

或

msg.channel.send({
files: [{
    attachment: 'entire/path/to/cbcfilter.png',
    name: 'cbcfilter.png'
  }]
})

在 discord.js v14 中，它已更改为 AttachmentBuilder

    return await interaction.editReply({
        content: responseText, 
        ephemeral: true,
        files: [new AttachmentBuilder(Buffer.from(codeResponseText), {name: 'codes.txt'})]
    });
