读取文件附件(例如；.txt 文件)- Discord.JS

问题描述

第二次在 StackOverflow 上发帖，如有错误，我深表歉意.请多多包涵.

与标题相同；您如何阅读不和谐附件的内容，比如 .txt 文件并打印内容?

我尝试使用 fs 但不幸失败了，我也搜索了文档但也失败了.

想法?

您不能为此使用 fs 模块，因为它只处理本地文件.当您将文件上传到 Discord 服务器时，它会被上传到 CDN，您所能做的就是从

Second time posting on StackOverflow so I apologize for any mistakes. Please bear with me.

Same with the title; How do you read contents of a discord attachment let's say a .txt file and print the contents?

I have tried with fs but unfortunately failed and I have also searched the documentation but failed also.

Ideas?

You can't use the fs module for this as it only deals with local files. When you upload a file to the Discord server, it gets uploaded to a CDN and all you can do is grab the URL of this file from the MessageAttachment using the url property.

If you need to get a file from the web, you can fetch it from a URL using the built-in https module, or you can install one from npm, like the one I used below, node-fetch.

To install node-fetch, run npm i node-fetch in your root folder.

Check out the working code below, it works fine with text files:

const { Client } = require('discord.js');
const fetch = require('node-fetch');

const client = new Client();

client.on('message', async (message) => {
  if (message.author.bot) return;

  // get the file's URL
  const file = message.attachments.first()?.url;
  if (!file) return console.log('No attached file found');

  try {
    message.channel.send('Reading the file! Fetching data...');

    // fetch the file from the external URL
    const response = await fetch(file);

    // if there was an error send a message with the status
    if (!response.ok)
      return message.channel.send(
        'There was an error with fetching the file:',
        response.statusText,
      );

    // take the response stream and read it to completion
    const text = await response.text();

    if (text) {
      message.channel.send(````${text}````);
    }
  } catch (error) {
    console.log(error);
  }
});
