AngularJS post 返回状态代码 304 而不是 post 正在播放后端

Question

我创建了一个简单的表格，如下所示

控制器如下

angular.module('clientApp')
   .controller('SignupCtrl', function ($scope, $http, $log, alertService, $location, userService) {

     $scope.signup = function() {
       var payload = {
         email : $scope.email,
         password : $scope.password
       };

       $http.post('app/signup', payload)
           .error(function(data, status) {
             if(status === 400) {
               angular.forEach(data, function(value, key) {
                 if(key === 'email' || key === 'password') {
                   alertService.add('danger', key + ' : ' + value);
                 } else {
                   alertService.add('danger', value.message);
                 }
               });
             }
             if(status === 500) {
               alertService.add('danger', 'Internal server error!');
             }
           })

     };
   });

我的看法如下

<form name="signupForm" ng-submit="signup()" novalidate>
 <div>
   <label for="email">Email</label>
   <input name="email" class="form-control" type="email" id="email" placeholder="Email"
          ng-model="email">
   </div>
 <div>
   <label for="password">Password</label>
   <input name="password" class="form-control" type="password" id="password"
          placeholder="Password" ng-model="password">

 </div>
 <button type="submit" class="btn btn-primary">Sign up!</button>
</form>

我的索引如下

//js files
<!-- bower:js -->
    <script src="bower_components/jquery/dist/jquery.js"></script>
    <script src="bower_components/angular/angular.js"></script>
    <script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>
    <script src="bower_components/angular-animate/angular-animate.js"></script>
    <script src="bower_components/angular-cookies/angular-cookies.js"></script>
    <script src="bower_components/angular-resource/angular-resource.js"></script>
    <script src="bower_components/angular-route/angular-route.js"></script>
    <script src="bower_components/angular-sanitize/angular-sanitize.js"></script>
    <script src="bower_components/angular-touch/angular-touch.js"></script>
    <script src="bower_components/angular-bootstrap/ui-bootstrap-tpls.js"></script>

我的app.js

angular
  .module('tripApp', [
    'ngAnimate',
    'ngCookies',
    'ngResource',
    'ngRoute',
    'ngSanitize',
    'ngTouch',
    'ui.bootstrap'
  ])
  .config(function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl',
        controllerAs: 'main'
      })
      .when('/signup', {
        templateUrl: 'views/signup.html',
        controller: 'SignupCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  });

当我执行 post 时，我在 post 连接到服务器时收到 304 GET 响应。它还将输入字符附加到我不喜欢的站点 url，因为它是 POST。请指教

Answer 1

304 表示 "Not Modified" - 内容已缓存。

尝试在您的 $http 配置中添加 "cache: false"。

我还建议您确认 "app/signup" 未被缓存（有时您可以按方法设置）
