Question

我尝试使用以下AngularJS代码从URL获取一些JSON数据：

'use strict';

/* Controllers */

var phonecatApp = angular.module('phonecatApp', []);

phonecatApp.controller('PhoneListCtrl', function($scope, $http) {
  $scope.test = "Not loaded";
  delete $http.defaults.headers.common['X-Requested-With'];
  $http.get('https://live.mpare.net/users.json').success(function(data) {
    $scope.test = data;
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });
  ;
});

但是，JSON文件未加载。如果我尝试使用其他网址，即http://ip.jsontest.com，则可以正常工作。

我使用curl检索了https网站的标题：

HTTP/1.1 200 OK
Date: Sat, 08 Nov 2014 10:53:04 GMT
Server: Apache/2.2.29 (Amazon)
X-Powered-By: PHP/5.3.29
Set-Cookie: PHPSESSID=epp00ffbe0nmtogpj8dcvnfvg2; path=/

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
Content-Length: 119
Connection: close
Content-Type: application/json

http网站的标题如下所示：

HTTP/1.1 200 OK

Server: Apache/2.2.29 (Amazon)
X-Powered-By: PHP/5.3.29

如何加载https JSON文件？

Answer 1

对于跨域你必须使用CORS，查看CORS here上的这篇文章，你可以使用jsonp，但是你不能用它来发帖。希望它有帮助

Answer 2

以下是有效的：

将$http.get替换为$http.jsonp，并将?callback=JSON_CALLBACK放在网址的末尾。以下代码对我有用：

'use strict';

/* Controllers */

var phonecatApp = angular.module('phonecatApp', []);

phonecatApp.controller('PhoneListCtrl', function($scope, $http) {
  $scope.test = "Not loaded";
  delete $http.defaults.headers.common['X-Requested-With'];
  $http.jsonp('https://live.mpare.net/users.json?callback=JSON_CALLBACK').success(function(data) {
    $scope.test = data;
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });
  ;
});

使用带有AngularJS的HTTPS URL加载JSON跨域
