当我开始使用我的应用程序上传文件时，它会在第一步后存货。上传功能的Bellow代码

exports.upload = function(req, res){
    var form = formidable.IncomingForm();
    console.log('Upload');
    form.parse(req, function(err, fields, files){
        if(err){
            console.log(err);            
            res.send(err);
            return;
        }
        console.log('Parsing');
        fs.readFile(files.image.path, function(err, data){
            if(err){
                res.send(err);
            }
            var imageName =  files.image.name;
            if(!imageName){
                console.log("Parsing issue - sending 500");
                res.writeHead(500, {'Content-type':'text/plain'});
                res.write('Parsing error');
                res.end();
                return;
            }
            var fullPath = photoDir + imageName;
            var thumbPath = thumbDir + imageName;
            fs.writeFile(fullPath, data, function(err){
                im.resize({
                    srcPath: fullPath,
                    dstPath: thumbPath,
                    width: 100
                },function(err, stdout, stderr){
                    if(err){
                        console.log(err);
                        res.send(err);
                        return;
                    }
                    var newPhoto = new Photo({
                        'fullsize_name':imageName,
                        'thumbsize_name':imageName
                    });
                    newPhoto.save(function(err){
                        if(err){
                            res.send(err);
                        }
                        res.json(newPhoto);
                        console.log(newPhoto);
                    });
                });
            });
        });
    });
}

服务器配置部分

var express = require('express');
var logger = require('morgan');
var body_parser = require('body-parser');
var mongoose = require('mongoose');
var passport = require('passport');
var multipart = require('connect-multiparty');
.
.
.
var app = express();
var router = express.Router();
var multipartMiddleware = multipart();
.
.
.
/** PHOTO OPERATIONS **/
router.route('/photos')
    .post(authController.isAuthenticated, photoController.upload);
.
.
.
app.use(passport.initialize());
app.use(logger('dev'));
app.use(multipartMiddleware);
app.use(body_parser.json());
app.use(body_parser.urlencoded({
    extended: true
}));

app.use('/api', router);

当我打电话

时，你知道为什么它会停止吗？

form.parse（req，function（err，fields，files）{

您是否在html文件中错过了表单标记中的{enctype ='multipart / form-data'}？添加它可能会有效。
