使用ytdl下载后,我在发送文件时遇到麻烦。我注意到这很奇怪,只要我手动为其命名(标题除外),它将成功将文件发送到服务器...否则,它仅将0字节文件发送到我的服务器。我尝试在标题方案上运行各种字符串方法,以为可能是错误的,但这是行不通的。我有一种预感,可能与以下方面有关:

但是,我不知道我一无是处。任何帮助将不胜感激。以下是我的消息来源。发送文件时出现问题的功能是命令==='ytm'
const Discord = require('discord.js'); //need discord.js library of course.
const config = require("./config.json"); //load up the token and prefix from our object configuration file.
const bot = new Discord.Client(); //establishing the bot as the client. "bot" means "client" when looking at the documentation!
bot.on('ready', () => {
console.log('I am ready!');
});
bot.on('message', message => {
if(message.author.bot) return; //prevents the bot from reacting to itself.
if(message.content.indexOf(config.prefix) !== 0) return; //reads out the first character of the message, and if its not our prefix we don't do break away
const args = message.content.slice(config.prefix.length).trim().split(/ +/g); //setting up to split things into arguments for handling commands, and usage of the prefix
const command = args.shift().toLowerCase();
if (command === 'ping') {
message.channel.send('pong');
//console.log(args);
//console.log(command);
}
if (command === 'ytm') {
const fs = require('fs');
const ytdl = require('ytdl-core');
url = args[0];
//console.log(ytdl.getURLVideoID(url));
//tried to actually work with the "title" information outside of the callback. apparently impossible?
ytdl.getInfo(url,function(err, info){
var title = info['title'];
var length = title.length;
title = title.substring(0, (length / 3));
title = title.trim();
title = './' + title + '.mp3'
console.log(title);
//console.log(info['size']);
ytdl(url, {filter:'audioonly', format:'mp3'}).pipe(fs.createWriteStream(title.toString()));
message.channel.send("Here's your mp3, boi.", {files:[(title)]});
//message.channel.sendFile(('./' + title), title, 'Heres your mp3, boi,'); //deprecated?
})
}
});
bot.login(config.token);
最佳答案
问题是您试图通过执行title = './' + title + '.mp3'
将title变量作为文件明确发送为文件,并将其发送为文件。您的问题是您正在尝试发送视频流而不是视频文件。 ytdl-core是显式用于流式传输视频而不是下载视频的模块。要获取和发送MP3文件,您必须改用youtube-dl(ytdl-core的基础)。文件下载完成后,它将发出一个事件,您可以通过Discord.js发送该事件。
