Question

我正在处理一个项目，我遇到麻烦，从我的angularJS前端发布表单数据到使用restangular的后端RESTful API。每次我尝试我得到一个错误代码400（错误的请求）。下面是我的代码

app.js

'use strict';

angular
    .module('clientApp', ['ngRoute', 'restangular'])
    .config(function ($routeProvider, RestangularProvider) {

    RestangularProvider.setBaseUrl('http://127.0.0.1:3000');

    $routeProvider
      .when('/', {
      templateUrl: 'views/login.html',
      controller: 'LoginCtrl',
      controllerAs: 'login'
    })

      .when('/create/user', {
      templateUrl: 'views/user-add.html',
      controller: 'UserAddCtrl',
      controllerAs: 'userAdd'
    })
     .otherwise({
      redirectTo: '/'
    });
    });

查看/ user.html

<div ng-controller="UserAddCtrl">

    <form class="form-horizontal" name="regForm" ng-submit="saveUser()">  
        <fieldset>

            <div class="form-group">
                  <label class="col-md-4 control-label" for="textinput">First Name</label>  
                  <div class="col-md-4">
                  <input id="Fname" name="Fname" type="text" ng-model="newUser.FnameValue" placeholder="Enter First Name" class="form-control input-md" required>

                  </div>
            </div>


            <div class="form-group">
                  <label class="col-md-4 control-label" for="Last Name">Last Name</label>  
                  <div class="col-md-4">
                  <input id="Lname" name="Lname" ng-model="newUser.LnameValue" type="text" placeholder="Enter Last Name" class="form-control input-md">

                  </div>
            </div>


            <div class="form-group">
                  <label class="col-md-4 control-label" for="Staff ID">Staff ID</label>  
                  <div class="col-md-4">
                  <input id="StaffId" name="StaffId" ng-model="newUser.StaffIdValue" type="text" placeholder="Enter Staff ID" class="form-control input-md" required>                   
                  </div>
            </div>


            <div class="form-group">
                  <label class="col-md-4 control-label" for="Email">Email</label>  
                  <div class="col-md-4">
                  <input id="Email" name="Email" ng-model="newUser.EmailValue" type="text" placeholder="Enter Email" class="form-control input-md" required="">

                  </div>
            </div>


            <div class="form-group">
                  <label class="col-md-4 control-label" for="Password">Password</label>
                  <div class="col-md-4">
                    <input id="Password" name="Password" ng-model="newUser.PasswordValue" type="password" placeholder="Enter Password" class="form-control input-md" required>

                  </div>
            </div>

            <div class="form-group">
                  <label class="col-md-4 control-label" for="Register"></label>
                  <div class="col-md-4">
                    <button id="Register" name="Register" type="submit" class="btn btn-primary">Creat User</button>
                  </div>
            </div>

        </fieldset>
    </form>

</div>

控制器/ user.js的

'use strict';

angular.module('clientApp')
  .controller('UserAddCtrl', function ($scope, Restangular, $location) {

     $scope.saveUser = function() {
         $scope.newUser = {};

         var restVar = Restangular.all('user');

         restVar.post($scope.newUser).then(function() {
             $location.path('/users');
             console.log('Success');
         }, function(response) {
             console.log('Error with status code', response.status);
         }); 
     };

 });

每次执行约代码时，我得到400（错误请求）......我做错了什么？

请注意我使用mongodb和我的数据库名称是isdbmeanapp，我的收藏名称是user，因此我的服务器网址是http://127.0.0.1:3000/user

在Restangular帖子中，应该对集合而不是元素。

在你的情况下，POST应该像这样;

$scope.newUser = {email :"", password: "", etc: ""};

然后发出POST请求;

Restangular.all('user').post("users", $scope.newUser);
