node expressjs – 使用body-parser中间件parsing多部分/表单数据POST数据
我张贴我的表单数据具有multipart/form-data enctype。 我使用了formiddable nodejs middlerware，之前只是为application/jsontypes工作。
我发现express.js有一个名为require('body-parser');的middlerware require('body-parser'); 这可以达到同样的目的。
这是我的app.js
var Express = require('express'); var Multer = require('multer'); var BodyParser = require('body-parser'); var app = Express(); app.use(BodyParser.json()); app.use(BodyParser.urlencoded({extended: false})); var storage = Multer.diskStorage({ destination: (req, file, callback) => { callback(null, './uploads'); }, filename: (req, file, callback) => { callback(null, file.fieldname + '-' + Date.now()); } }); var upload = Multer({storage: storage}).single('songUpload'); app.post('/artists', (req, resp) => { var song = req.body //its empty, {} console.log(req.body.album) // its undefined console.dir(song) upload(req, resp, (err) => { if (err) { return resp.end("Error uploading file, " + err); } resp.render("artists/profile", {artistName: "UPD : Radio for Dreams"}); }); })
窗体视图是
<form id="musicUpload" method="POST" enctype="multipart/form-data"> <fieldset> <label for="album">Album</label> <input name="album"/> <br/> <label for="song"> Song </label> <input name="email"/> <br/> <label for="songUpload"> Upload audio </label> <input name="songUpload" type="file" multifile="multifile"> <br/> <label for="tags"> Tags </label> <input name="message"/> <br/> <input type="submit" value="Share to listeners"> </fieldset> </form>
具有Content-Type:multipart/form-data的http请求如下所示，
Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding:gzip, deflate Accept-Language:en-US,en;q=0.8,en-GB;q=0.6 Cache-Control:max-age=0 Connection:keep-alive Content-Length:509 Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryCSC5Po9i0QGe587Z Host:localhost:3000 Origin:http://localhost:3000 Referer:http://localhost:3000/artists Upgrade-Insecure-Requests:1 User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.143 Safari/537.36
而且，发布的数据是
但是，在服务器端，我无法使用express.jsparsing器获取发布的数据。 它全是空的。
您需要将multer中间件调用添加到您的路由处理程序中：
app.post('/artists', upload, (req, resp) =>
