我在使用angularjs构建单页应用时遇到问题。我的应用程序有一个登录页面。如果身份验证成功,则应用程序将路由到主页,其中从$ scope显示一些数据。但是,登录后没有数据显示。

我在登录成功时使用location.path路由到家。作为参考,我正在尝试打印" $ scope.homePageDetails"在home.html但没有任何东西被打印。有人可以说,我做错了什么,我该如何解决这个问题?

index.html文件:

<html>
    <body>
   <nav>
   <ul>
   <li ng-hide="isUserLoggedIn"><a href="#login">       <span class="glyphicon glyphicon-log-in"></span> Login</a></li>
  </ul>
  </nav>    

 <div ng-view></div>
</body>
</html>

login.html文件:

<div>
 <form class="form-signin">
   <input type="text" class="form-control" placeholder="Email" ng-model="userDetails.userName" required autofocus>
  <input type="password" class="form-control" placeholder="Password" ng-model="userDetails.Password" required>
  <button class="btn btn-lg btn-primary btn-block" type="submit" ng-click="signIn()">
Sign in</button>
</form>            

home.html的:

<p> {{homePageDetails}}</p>

角度模块和控制器:

app.controller('myCtrl', ['$scope','$http', '$location'    function($scope,$uibModal,$http, $location, $window) {
$scope.signIn = function(){

    $http({
    url: "http://localhost:3050/postSignIn",
    method: "POST",        
    headers: {'Content-Type': 'application/json; charset=utf-8'
       },
    data: $scope.userDetails
    })
    .then(function(response){
            console.log('resp is',response);
            $scope.isUserLoggedIn = true;               
            $location.path('/home');

              $http({
                    url: "http://localhost:3050/getHomePageDetails",
                    method: "GET",        
                    headers: {'Content-Type': 'application/json; charset=utf-8'
                   }        
               })
               .then(function(response){                       
                   $scope.homePageDetails = response.data.slice(0);
               }, function(response){
                // failure callback
                console.log('failure in getting homePageDetails',response);
               });                   
        },        
        function(response){
            // failure callback
            console.log('failure is',response);
        });     
}
}]);

模块:

var app = angular.module('myApp', ['ngRoute']);

路由器:

app.config(function ($routeProvider, $locationProvider, $httpProvider) {

$routeProvider.when('/home',
{
  templateUrl:    'home.html',
  controller:     'myCtrl'
});

}

你可以试试这个

$routeProvider
.when('/home',
{
  templateUrl:    'home.html',
  controller:     'myCtrl'
})
.when('/login',
{
 templateUrl:'login.html',
controller:'myCtrl'
})
