register.jade是...
表单加载正常并且看起来是正确的

user.js是...
console.log语句中的值在控制台输出中未定义。
post方法不能从表单中发送任何内容。
提交后将显示users.js errors数组中的值。
可能的语法错误，但我没有看到它。
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
router.get('/register', function(req, res, next) {
res.render('register', {
'title': 'Register'
});
});
router.get('/login', function(req, res, next) {
res.render('login', {
'title': 'LogIn'
});
});
router.post('/register', function(req, res, next) {
// Get form values
var name = req.body.name;
var email = req.body.email;
var username = req.body.username;
var password = req.body.password;
var password2 = req.body.password2;
console.log('Name is... ', name);
console.log('reqName... ', req.body.name);
console.log('PW is... ', password);
console.log('PW2 is.. ', password2);
// Check for image field
if (req.body.profileimage) {
console.log('Uploading file...');
// File info
var profileImageOriginalName = req.files.profileimage.originalname;
var profileImageName = req.files.profileimage.name;
var profileImageMime = req.files.profileimage.mimetype;
var profileImagePath = req.files.profileimage.path;
var profileImageExt = req.files.profileimage.extension;
var profileImageSize = req.files.profileimage.size;
} else {
var profileImageName = 'noimage.png'; // default image
}
// Form validation using Express validator
req.checkBody('name', 'Name is required').notEmpty();
req.checkBody('email', 'Valid Email is required').notEmpty();
req.checkBody('email', 'Email is not valid').isEmail();
req.checkBody('username', 'Username is required').notEmpty();
req.checkBody('password', 'Password is required').notEmpty();
req.checkBody('password2', 'Passwords do not match').equals(req.body.password);
// Check for errors
var errors = req.validationErrors();
if (errors) {
res.render('register', { // Pass values back in so user does not have to retype
errors: errors,
name: name,
email: email,
username: username,
password: password,
password2: password2
});
} else {
// Create user object
var newUser = new User({
name: name,
email: email,
username: username,
password: password,
profileimage: profileImageName
});
// Create user
User.createUser(newUser, function(err, user){
if (err) throw err;
console.log(user);
});
// Success
req.flash('success', 'You are registered and may now login');
res.location('/');
res.redirect('/');
}
});
module.exports = router;
另外文件在以下情况下似乎无效......
if (req.files.profileimage) console.log('Uploading file...');
改为......
if (req.body.profileimage) console.log('Uploading file...');
但尚未测试。
中间件......

});
module.exports = app;
与Multer安装的npm不喜欢......
app.use(multer({dest: './uploads'}));
所以我把它改成了......
var upload = multer({ dest: './uploads' });
不确定会导致什么样的问题
答案 0 :(得分：1)
我之前面对的问题完全相同。作为解决问题的方法，我使用npm命令将 connect-multiparty 模块添加到我的项目中：
npm install connect-multiparty --save
然后我在快速变量定义之后的路由文件（user.js）之上添加代码。
var express = require('express');
..
var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();
最后我在接受文件上传的路由器中使用 multipartMiddleware 。
...
router.post('/register', multipartMiddleware, function(req, res, next){
...
...
}
请注意，建议不要在所有路线中使用此模块，仅将其用于您要接受上传的路线。查看文档以获取更多详细信息https://www.npmjs.com/package/connect-multiparty

使用multer你需要像中间件一样插入它：
var multer = require('multer');
var upload = multer({dest: 'uploads/'});
var fileLoad = upload.single('profileImage');
router.route('/register')
.post(fileLoad, function (req, res) {
.......
}
