Express / torrent-stream：从stream中写入文件，使用url将套接字发送给客户端，但客户端无法find文件

我正在开发一个个人项目，基本上需要一个磁铁链接，开始下载文件，然后在浏览器中呈现video的洪stream。 我使用一个名为torrent-stream的npm模块来完成大部分的工作。 一旦我创build了可读stream并开始写文件，我想用videoURL向客户端发送套接字消息，以便客户端可以呈现html5video元素并开始stream式传输video。

我遇到的问题是，一旦客户端呈现video元素，并试图find源mp4我得到一个404video文件中找不到错误。 任何意见，这将是高度赞赏队友。 🙂

控制器function：

uploadVideo: function (req, res) { var torrentStream = require('torrent-stream'); var mkdirp = require('mkdirp'); var rootPath = process.cwd(); var magnetLink = req.param('magnet_link'); var fs = require('fs'); var engine = torrentStream(magnetLink); engine.on('ready', function() { engine.files.forEach(function(file) { var fileName = file.name; var filePath = file.path; console.log(fileName + ' - ' + filePath); var stream = file.createReadStream(); mkdirp(rootPath + '/assets/videos/' + fileName, function (err) { if (err) { console.log(err); } else { var videoPath = rootPath + '/assets/videos/' + fileName + '/video.mp4'; var writer = fs.createWriteStream(videoPath); var videoSent = false; stream.on('data', function (data) { writer.write(data); if (!videoSent) { fs.exists(videoPath, function(exists) { if (exists) { sails.sockets.broadcast(req.param('room'), 'video_ready', {videoPath: '/videos/' + fileName + '/video.mp4'}); videoSent = true; } }); } }); // stream is readable stream to containing the file content } }); }); }); res.json({status: 'downloading'}); } 

客户端javascript：

 $(document).ready(function () { io.socket.on('connect', function () { console.log('mrah'); io.socket.get('/join', {roomName: 'cowboybebop'}); io.socket.on('message', function (data) { console.log(data); }); io.socket.on('video_ready', function (data) { var video = $('<video width="320" height="240" controls>\ <source src="' + data.videoPath + '" type="video/mp4">\ Your browser does not support the video tag.\ </video>'); $('body').append(video); }); }); $('form').submit(function (e) { e.preventDefault(); var formData = $(this).serialize(); $.ajax({ url: '/upload-torrent', method: 'POST', data: formData }).success(function (data) { console.log(data); }).error(function (err) { console.log(err); }); }); }); 

形成：
