//Create an Angular Module.
var newsModule = angular.module('NewsModule', []);
//Create an Angular Controller.
newsModule.controller('newsCtrl', ['$scope', '$http', function ($scope, $http) {
//function retrives POST,UPDATE,DELETE,GET data
$http.defaults.headers.put = {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',
'Access-Control-Allow-Headers': 'Content-Type, X-Requested-With'
};
$http.defaults.useXDomain = true;
$scope.throughdata = function (){
delete $http.defaults.headers.common['X-Requested-With'];
$http.get('http://www.google.com').then(function(data,error){
alert(data);
alert(error);
$scope.days=data.data;
});
}
}
]);
但我有以下错误
XMLHttpRequest无法加载http://www.google.com/ . 请求的资源上不存在“Access-Control-Allow-Origin”标头 . 因此不允许原点'null'访问 .

Access-Control-Allow-Originis set on the response from server ， not on client request 允许来自不同来源的客户端访问响应 .在您的情况下，http://www.google.com/不允许您的来源访问响应 . 因此你无法阅读它 .
