Javascript 使用angular.js和node.js从表单上传照片和其他信息

需要使用node.js、express和angular（前端）上传照片并将其保存到本地文件夹的帮助。表单完成后，将新用户信息保存到mongoose工作正常。需要添加照片上传部分。 注意：我已经阅读了所有的教程，但我似乎无法将它们与我已经构建的内容集成或使用。请帮忙

我的项目结构如下所示-

注册表的控制器文件（node.js后端）（api/controllers/user.controller.js）

module.exports.register = function(req, res){

  // Create new user 
  console.log("Registering Users");
  var email = req.body.email;
  var fname = req.body.fname;
  var lname = req.body.lname;
  var password = req.body.password;

  User.create({
      email: email,
      fname: fname,
      lname: lname,
      password: bcrypt.hashSync(password, bcrypt.genSaltSync(10))
    }, function(err, user){
      if(err){
        console.log(err);
        res.status(400).json(err);
      } else {
        console.log("User created", user);
        res.status(201).json(user);
      }
    }
  );
};

var express = require('express');
var router = express.Router();

var ctrlUsers = require('../controllers/users.controller.js');

router
  .route('/register')
  .post(ctrlUsers.register);

module.exports = router;

angular.module('login').controller('RegisterController', RegisterController);

function RegisterController($http){
  var vm = this;

  vm.register = function(){
    var user = {
      email: vm.email,
      fname: vm.fname,
      lname: vm.lname,
      password: vm.password
    };

    if(!vm.email || !vm.password){
      vm.error = 'Please enter an email and password.';
    } else {
      if(vm.password !== vm.passwordRepeat){
        vm.error = 'Please enter matching passwords.';
      } else {
        console.log(user);
        $http.post('/api/register', user).then(function(result){
          console.log(result);
          console.log(user);
          vm.message = 'Successful login! Hello,' + ' ' + vm.fname + ' ' + vm.lname + '.';
          vm.error= '';
        }).catch(function(error){
          console.log(error);
        });
      }
    }
  }
};

index.js文件（node.js后端路由）（api/routes/index.js）

module.exports.register = function(req, res){

  // Create new user 
  console.log("Registering Users");
  var email = req.body.email;
  var fname = req.body.fname;
  var lname = req.body.lname;
  var password = req.body.password;

  User.create({
      email: email,
      fname: fname,
      lname: lname,
      password: bcrypt.hashSync(password, bcrypt.genSaltSync(10))
    }, function(err, user){
      if(err){
        console.log(err);
        res.status(400).json(err);
      } else {
        console.log("User created", user);
        res.status(201).json(user);
      }
    }
  );
};

var express = require('express');
var router = express.Router();

var ctrlUsers = require('../controllers/users.controller.js');

router
  .route('/register')
  .post(ctrlUsers.register);

module.exports = router;

angular.module('login').controller('RegisterController', RegisterController);

function RegisterController($http){
  var vm = this;

  vm.register = function(){
    var user = {
      email: vm.email,
      fname: vm.fname,
      lname: vm.lname,
      password: vm.password
    };

    if(!vm.email || !vm.password){
      vm.error = 'Please enter an email and password.';
    } else {
      if(vm.password !== vm.passwordRepeat){
        vm.error = 'Please enter matching passwords.';
      } else {
        console.log(user);
        $http.post('/api/register', user).then(function(result){
          console.log(result);
          console.log(user);
          vm.message = 'Successful login! Hello,' + ' ' + vm.fname + ' ' + vm.lname + '.';
          vm.error= '';
        }).catch(function(error){
          console.log(error);
        });
      }
    }

注册表HTML文件-（public/angular app/Registration/Registration.HTML）

欢迎！
{{vm.message}}

{{vm.error}}

电子邮件
…其他一些领域。。。
上传照片
提交

使用FormData：

var formData = new FormData()
formData.append("profilePicture",vm.profilePicture);
formData.append("email",vm.email);
formData.append("fname",vm.fname);
formData.append("lname",vm.lname);
formData.append("password",vm.password);

 $http.post('/api/register', formData).then(function(result){
          console.log(result);
          console.log(user);
          vm.message = 'Successful login! Hello,' + ' ' + vm.fname + ' ' + vm.lname +'.';
          vm.error= '';
        }).catch(function(error){
          console.log(error);
        });
