ExpressJS问题：
大多数中间件已从express
4中删除。签出：http :
//www.github.com/senchalabs/connect#middleware
对于多部分中间件，如busboy，busboy-connect，强大，流程，parted是必需的。
此示例使用 connect-busboy 中间件工作。创建/ img和/ public文件夹。
使用文件夹结构：
server.js
img “资料上传到的位置”
public index.html
SERVER.JS
var express = require('express'); //Express Web Server var busboy = require('connect-busboy'); //middleware for form/file uploadvar path = require('path'); //used for file pathvar fs = require('fs-extra'); //File System - for file manipulationvar app = express();app.use(busboy());app.use(express.static(path.join(__dirname, 'public')));app.route('/upload') .post(function (req, res, next) { var fstream; req.pipe(req.busboy); req.busboy.on('file', function (fieldname, file, filename) { console.log("Uploading: " + filename); //Path where image will be uploaded fstream = fs.createWriteStream(__dirname + '/img/' + filename); file.pipe(fstream); fstream.on('close', function () { console.log("Upload Finished of " + filename); res.redirect('back');//where to go next }); }); });var server = app.listen(3030, function() { console.log('Listening on port %d', server.address().port);});INDEX.HTML
<!DOCTYPE html><html lang="en" ng-app="APP"><head> <meta charset="UTF-8"> <title>angular file upload</title></head><body> <form method='post' action='upload' enctype="multipart/form-data"> <input type='file' name='fileUploaded'> <input type='submit'> </body></html>
以下将适用于强大的 SERVER.JS
var express = require('express'); //Express Web Server var bodyParser = require('body-parser'); //connects bodyParsing middlewarevar formidable = require('formidable');var path = require('path'); //used for file pathvar fs =require('fs-extra'); //File System-needed for renaming file etcvar app = express();app.use(express.static(path.join(__dirname, 'public')));app.use(bodyParser({defer: true})); app.route('/upload') .post(function (req, res, next) { var form = new formidable.IncomingForm(); //Formidable uploads to operating systems tmp dir by default form.uploadDir = "./img"; //set upload directory form.keepExtensions = true; //keep file extension form.parse(req, function(err, fields, files) { res.writeHead(200, {'content-type': 'text/plain'}); res.write('received upload:nn'); console.log("form.bytesReceived"); //TESTING console.log("file size: "+JSON.stringify(files.fileUploaded.size)); console.log("file path: "+JSON.stringify(files.fileUploaded.path)); console.log("file name: "+JSON.stringify(files.fileUploaded.name)); console.log("file type: "+JSON.stringify(files.fileUploaded.type)); console.log("astModifiedDate: "+JSON.stringify(files.fileUploaded.lastModifiedDate)); //Formidable changes the name of the uploaded file //Rename the file to its original name fs.rename(files.fileUploaded.path, './img/'+files.fileUploaded.name, function(err) { if (err) throw err; console.log('renamed complete'); }); res.end(); });});var server = app.listen(3030, function() {console.log('Listening on port %d', server.address().port);});
