node.js如何上传图片

Question

现在看的是node.js实战这本书，书上说bodyParser()更具体的说是multipart()中间件他会给你一个req.files对象，代表上传的对象。我照着书上的代码敲的，结果总是undefined，Cannot read property ‘photo’ of undefined。搜了下body-parser，看到上面写着This does not handle multipart bodies, due to their complex and typically large nature.For multipart bodies, you may be interested in the following modules:意思是不是body-parser模块不再支持multipart。下面app.js有代码：var bodyParser = require('body-parser');app.use(bodyParser.json());app.use(bodyParser.urlencoded({ extended: false }));app.set('photos',__dirname+'/public/photos');app.get('/upload',photos.form);app.post('/upload',photos.submit(app.get('photos')));photo.js里有代码：

body-parser 不能够处理 multipart/form-data 了。需要使用 multer 中间件。
