Question

我尝试制作注册表并保存到数据库（通过mLab云数据库），但是在提交表单后，服务器无法获取数据，也没有响应。我是MEAN Stack的新手，请告知我是否犯了任何愚蠢的错误。非常感谢提前。

controller.js

const bodyparser = require('body-parser');
const userModel = require('../model/userModel');app.use(bodyparser.urlencoded({extended:true}));

//create acc
app.post('/userSignUp', function(req, res){
  if (!req.body) return res.sendStatus(404);

  var newUser = new userModel({
    username: req.body.username,
    password: req.body.password
  });

  //save user to db
  newUser.save(function(err){
    if (err) throw err;

  // fetch user and test password verification
  userModel.findOne({username:req.body.username}, function(err, user){
    if (err) throw err;

    // test a matching password
    user.comparePassword(req.body.password, function(err, isMatch){
      if (err) throw err;
      console.log(req.body.password, isMatch);
      res.render('/index.ejs');
    });
  });
});});

注册表格

<!-- Sign up form -->
    <div id="signup_form" style="width:50%; margin:0 auto;">
        <h1>Sign up</h1>
        <form action="userSignUp" method="get">
                    <input type="text" name="username" placeholder="username">
                    <input type="password" name="password" placeholder="password">
                    <span>
                            <input type="checkbox" name="checkbox">
                            <label for="checkbox">remember</label>
                    </span>
                    <input type="submit" value="Sign Up">
            </form>
    </div>

的usermodel

var mongoose = require('mongoose'),
Schema = mongoose.Schema,
bcrypt = require('bcrypt'),
SALT_WORK_FACTOR = 10;

var UserSchema = new Schema({
username: { type: String, required: true, index: { unique: true } },
password: { type: String, required: true }

}）;

UserSchema.pre('save', function(next) {
var user = this;

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

// generate a salt
bcrypt.genSalt(SALT_WORK_FACTOR, function(err, salt) {
if (err) return next(err);

// hash the password using our new salt
bcrypt.hash(user.password, salt, function(err, hash) {
    if (err) return next(err);

    // override the cleartext password with the hashed one
    user.password = hash;
    next();
});

}）;

UserSchema.methods.comparePassword = function(candidatePassword, cb) {
bcrypt.compare(candidatePassword, this.password, function(err, isMatch) {
    if (err) return cb(err);
    cb(null, isMatch);
});

};

module.exports = mongoose.model('User', UserSchema);

您在使用app.post

的快速路由器中使用get方法

使用方法=＆＃34;发布＆＃34;这样你就可以从body.property

获得

<form action="userSignUp" method="post">
