Multer不填充req.body和req.file

我使用Multer解析在梯形环境多形式，并且不能够进入我的路由控制器内req.body和req.file数据Multer不填充req.body和req.file

路线/ index.js

var keystone = require('keystone'), 
    middleware = require('./middleware'); 

var bodyParser = require('body-parser'); 

//multi-part form parser for FTP api 
var multer = require('multer'); 
var storage = multer.memoryStorage(); 
var upload = multer({storage: storage}); 

exports = module.exports = function(app) { 
    app.use(bodyParser.json({limit: '10mb'})); 
    app.use(bodyParser.urlencoded({limit: '10mb', extended: true})); 
    app.post('/upload_api', upload.single('formFile'), routes.api.uploadFTP); 
};

路线/ API/uploadFTP.js

var keystone = require('keystone'); 
var ftpMod = require('ftp'); 
var fs = require('fs'); 

exports = module.exports = function(req, res) { 
    console.log("req.body is "); 
    console.log(req.body); 
    console.log("req.file is "); 
    console.log(req.file); 
    res.send("console.log() outputted to screen"); 
}

公共/测试upload.html

<html> 
    <body> 
     <form name="sampleForm" enctype="multipart/form-data" action="/upload_api" method="post"> 
      <p>Method</p> 
      <input type="text" name="method"><br> 
      <p>Options</p> 
      <input type="text" name="options"><br> 
      <p>File</p> 
      <input type="file" name="formFile"><br><br> 
      <input type="submit" value="Click to Send"> 
     </form> 
    </body> 
</html>

我来自的NodeJS收到的反应是

>req.body is 
{} 
req.file is 
undefined

我期待req.body包含{方法：“SomeText”则会} 和req.file要填充

在你不能得到的值或者req.body或req.file。用下面给出的代码替换youe uploadFTP.js。

var multer = require('multer'); 
var path = require('path'); 

var storage = multer.diskStorage({ 
    destination: function(req, file, callback) { 
    callback(null, <<path where you want to store your files>>); 
    }, 
    filename: function(req, file, callback) { 
    callback(null, path.basename(Date.now() + '_' + file.originalname)); 
    }, 
}); 
var maxSize = 1024 * 1024; 
var upload = multer({ 
    storage: storage, 
    fileFilter: function(req, file, callback) { 
    var ext = path.extname(file.originalname); 
    if(ext !== '.gif' && ext !== '.jpeg') { 
     return callback(res.status(202).end();, null); 
    } 
    callback(null, true); 
    }, 
    limits: {fileSize: maxSize}, 
}).single('image'); 

exports = module.exports = function (req, res) { 

    upload(req, res, function(err) { 
    console.log(storage.diskStorage); 
    if(err) { 
     return res.status(201).end(); 
    } 
    //Do stuff here 
    res.status(200).end(); 
    }); 
}

替换下面线在index.js

app.post('/upload_api', upload.single('formFile'), routes.api.uploadFTP);

与

app.post('/upload_api', routes.api.uploadFTP);

林困惑除去'upload.single（ 'formFile'）从index.js '中间件我也对uploadFTP.js文件中的函数upload（req，res，function（err）{}）感到困惑： upload.single（）去哪了？这一切看起来都与Express/Muller – user258667

提供的文档大不相同。文档中的示例代码是 var multer = require（'multer'）; var storage = multer.memoryStorage（）; var upload = multer（{storage：storage}）; app.post（'/ profile'，upload.array（），function（req，res，next）{//要求包含文本字段 }）; – user258667

这是我的应用程序的工作代码。如果你愿意，你可以保留中间件。我已经从实际的方法 –
