Question

我有一个REST服务。哪个有JWT授权。要获取令牌，您需要将POST请求发送到＆＃39; / login＆＃39;使用JSON的端点：

{
  'username':'username',
  'password':'password'
}

之后你会收到JSON，例如：

{
  'token': "a1a1.b2b2.c3c3"
}

我是AngularJS和JavaScript本身的新手，所以我现在正在玩基础知识。只是试图从登录服务中获取令牌。

的index.html

<!DOCTYPE html>
<html ng-app="app">

<head>
   <meta charset="UTF-8">
   <title>app</title>
   <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
   <script src="app.js"></script>
   <script src="service.js"></script>
</head>

<body class="container" ng-controller="AppController as app">
 <div ng-controller="ServiceController as service">
   <p>{{service.login()}}</p>
 </div>
</body>

</html>

app.js

(function () {
  var app = angular.module('app',['service']);

  app.controller('AppController', function () {
  });
})();

service.js

angular.module('service', [])
.controller('ServiceController', ['$http', function ($http){
   var url = 'http://localhost:8080/login';
   var resp = 'lol';
  var credentials = { 'username' : "username", 'password' : "password" };

  this.getToken = function () {
    return $http.post(url, credentials).success(function(response) {
        angular.forEach(response.data.token, function(token) {
            resp = token;
        });
    });
    };

 this.getToken();

 this.login = function () {
     return resp;
 };

}]);

因此，当我打开index.html时，它让我大声笑而不是我期待的JSON响应。那有什么不对吗？

EDIT2：

service.js

angular.module('service', [])
.controller('ServiceController', ['$http', function ($http){
   var url = 'http://localhost:8080/login';
   var resp = 'lol';
  var credentials = { 'username' : "username", 'password' : "password" };
 $http.defaults.headers.common['Content-Type']= 'application/json';
 $http.defaults.headers.common['Access-Control-Allow-Origin'] = '*';

 *this.getToken = function () {
    return $http.post(url, credentials).success(function(response) {
            resp = response.data.token;
    });
    };*

 this.getToken();

 this.login = function () {
     return resp;
 };

}]);
