即使表單正確填寫，我的快速驗證也會返回錯誤

Question

我已經為此戰斗了一段時間，我有這個Nodejs Express應用程序，當表單字段無效時，我的注冊表單會返回一堆驗證錯誤，這是一件好事，但是，當表單正確填寫后，它仍然會返回這些錯誤，並且不提交任何數據。

這是用於注冊的代碼route.post

router.post('/register', function(req, res, next){
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;

// Check for image field
if(req.files && req.files.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.file.profileimage.path;
    var profileImageExt             = req.files.profileimage.extension;
    var profileImageSize            = req.files.profileimage.size;

}else {
    // Set a Default Image
    var profileImageName = 'noimage.png';
}

// Form validation
req.checkBody('name', 'Name is required').notEmpty();
req.checkBody('email', 'Email is required').notEmpty();
req.checkBody('email', 'Invalid Email ID').isEmail();
req.checkBody('username', 'Username is required').notEmpty();
req.checkBody('password', 'Password field is required').notEmpty();
req.checkBody('password2', 'Password do not match').equals(req.body.password);

// Check for Validation errors
var errors = req.validationErrors();

if(errors){
    res.render('register', {
        errors: errors,
        name: name,
        email: email,
        username: username,
        password: password,
        password2: password2
    });
}else {
    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 Message
    req.flash('success', 'You are now registered and may log in');

    res.location('/');
    res.redirect('/');
}
});

這是我的register.jade代碼

extends layout
block content
    h1 Register
    p Please register using the form below
    ul.errors
        if errors
            each error, i in errors
                li.alert.alert-danger #{error.msg}
    form(method='post', action='/users/register', enctype='multipart/form-data')
        .form-group
            label Name
            input.form-control(name='name', type='text', placeholder='Enter Name')
        .form-group
            label Email
            input.form-control(name='email', type='text', placeholder='Enter Email')
        .form-group
            label Username
            input.form-control(name='username', type='text', placeholder='Enter Username')
        .form-group
            label Password
            input.form-control(name='password', type='password', placeholder='Enter Password')
        .form-group
            label Confirm Password
            input.form-control(name='password2', type='password', placeholder='Confirm Password')
        .form-group
            label Profile Image
            input.form-control(name='profileimage', type='file')
        input.btn.btn-default(name='submit', type='submit', value='Register')

請任何幫助將不勝感激...謝謝

正文解析器不適用於將多部分表單屬性設置為表單數據的情況，而是將其設置為urlencoded

<form action="/register" method="post" multipart="urlencoded"></form>

這樣你就應該好！ 謝謝大家的時間。 祝好運

1) Use body parser and express-validator before router you used
2) if you use multipart/form-data then you use validator middleware after multer file upload strategy 

這是我的工作

var validator = function(req,res,next){
  req.checkBody('name').notEmpty().withMessage('Name field is required');
}

router.post('/upload',multer.single('avatar'),validator,function(req,res,next){
  //req.body
  //req.file 
 both object available here 
})
