跨源请求被阻止：同源策略不允许在离子框架中使用angularjs

Question

我已使用以下代码

将令牌设置为我的请求的标头

$http.defaults.headers.common['X-Auth-Token'] = 'mytoken';

我的firebug中显示的请求标题如下。

X-Auth-Token    mytoken
X-Powered-By    PHP/5.5.9-1ubuntu4.13
access-control-allow-orig...    *

在我的服务器端代码中，我添加了以下行

 header("Access-Control-Allow-Origin: *");
 header("x-auth-token: mytoken");

我仍然收到以下错误

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost/app/item/get. (Reason: missing token 'x-auth-token' in CORS header 'Access-Control-Allow-Headers' from CORS preflight channel).

 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost/app/item/get. (Reason: CORS request failed).

如果我删除下面的标记标题，一切正常

 $http.defaults.headers.common['X-Auth-Token'] = 'mytoken';
