为什么我的节点验证在此 POST 中失败？

Question

我正在学习 MEAN machine 节点身份验证教程。

这是他们的源代码：https://github.com/scotch-io/mean-machine-code/blob/master/10-node-authentication/server.js除了apiRouter.post('/authenticate',部分

，我基本上什么都有

Express API 正在运行： http://localhost:8615/api/users 将 return 来自 scotch.io 的 MongoDB

的用户列表

以下是/api/users的API:

apiRouter.route('/users')

// create a user (accessed at POST http://localhost:8615/api/users)
.post(function(req, res) {

    // create a new instance of the User model
    var user = new User();

    // set the users information (comes from the request)
    user.name = req.body.name;
    user.username = req.body.username;
    user.password = req.body.password;

    // save the user and check for errors
    user.save(function(err) {
        if (err) {
            // duplicate entry
            if (err.code == 11000) 
                return res.json({ success: false, message: 'A user with that username already exists. '});
            else 
                return res.send(err);
        }

        // return a message
        res.json({ message: 'User created!' });
    });

})

// get all users (access at GET http://localhost:8615/api/users)
.get(function(req, res) {
    User.find(function(err, users) {
        if (err) return res.send(err);

        // return the users
        res.json(users);
    })
});

这是我的 user.js 用户架构

// SCHEMAS ------------------------------------
// user schema
var UserSchema = new Schema({
    name: String,
    username: { type: String, required: true, index: { unique: true }},
    password: { type: String, required: true, select: false }
    // ^ select false will not return passwords
});


// hash the password before the user is saved
UserSchema.pre('save', function(next) {
    var user = this;

    // PUT username
    if (!user.isModified('username')) return next();

    // PUT name
    if (!user.isModified('name')) return next();

    // hash the password only if the password has been changed or user is new
    if (!user.isModifited('password')) return next();

    // generate the salt
    bcrypt.hash(user.password, null, null, function(err, hash) {
        if (err) return next(err);

        // change the password to the hashed version
        user.password = hash;
        next();
    });
});

摘自本书：

Create a Sample User

First, we need to make sure that we even have a user to authenticate since towards the end of last chapter, we deleted everyone. Let’s create the user using the POST http://localhost:8080/api/users route we created in our API to add a user to our database.

We will send a POST request with the following information: Name Chris Username chris Password supersecret

我正在使用 Postman 添加新用户，如您所见，我已经输入了 key/value 对用户名和密码，但是收到一条错误消息 "Validation failed" "username is required" "password is required":

更新，我刚刚尝试了 x-www-form-urlencoded 并收到以下错误

GET /api/users 200 66.141 ms - 655
••• API CRUD hit •••

/Users/leongaban/NodeDallas/projects/awesome-test/app/models/user.js:27
    if (!user.isModifited('password')) return next();
          ^

Answer 1

您想将 json 推送到您的服务器。 Select raw 并将数据类型设置为 JSON.

那么您只需在此处以 JSON 格式填写您的用户及其所有字段。

{
   "name": "Chris",
   "username": "chris",
   "password": "supersecret"
}

Answer 2

在邮递员中尝试 x-www-form-urlencoded，就可以了。

为什么我的节点验证在此 POST 中失败？

Why is my Node validation failing in this POST?
