Some time ago I had a task for the company where I work. The task had to use CORS. I am writing this article to share lesson learned.
You want to send POST request to different domain with AngularJS $http service? There is several tricky thing into AngularJS and server setup.
First:
In your application config you must to allow cross domain call
/**
* Cors usage example.
* @author Georgi Naumov
* gonaumov@gmail.com for contacts and
* suggestions.
**/
app.config(function($httpProvider) {
//Enable cross domain calls
$httpProvider.defaults.useXDomain = true;
});
Second:
You must specify withCredentials: true and username and password into
request.
/**
* Cors usage example.
* @author Georgi Naumov
* gonaumov@gmail.com for contacts and
* suggestions.
**/
$http({
url: 'url of remote service',
method: "POST",
data: JSON.stringify(requestData),
withCredentials: true,
headers: {
'Authorization': 'Basic bashe64usename:password'
}
});
Тhird:
Server setup. You must provide:
/**
* Cors usage example.
* @author Georgi Naumov
* gonaumov@gmail.com for contacts and
* suggestions.
**/
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://url.com:8080");
header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
For every request. When you receive OPTION you must pass:
/**
* Cors usage example.
* @author Georgi Naumov
* gonaumov@gmail.com for contacts and
* suggestions.
**/
if($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
header( "HTTP/1.1 200 OK" );
exit();
}
HTTP authentication and everything else comes after that.
Here is complete example of usage of server side with php.
/**
* Cors usage example.
* @author Georgi Naumov
* gonaumov@gmail.com for contacts and
* suggestions.
**/
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: http://url:8080");
header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept, Authorization");
if($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
header( "HTTP/1.1 200 OK" );
exit();
}
$realm = 'Restricted area';
$password = 'somepassword';
$users = array('someusername' => $password);
if (isset($_SERVER['PHP_AUTH_USER']) == false || isset($_SERVER['PHP_AUTH_PW']) == false) {
header('WWW-Authenticate: Basic realm="My Realm"');
die('Not authorised');
}
if (isset($users[$_SERVER['PHP_AUTH_USER']]) && $users[$_SERVER['PHP_AUTH_USER']] == $password)
{
header( "HTTP/1.1 200 OK" );
echo 'You are logged in!' ;
exit();
}
?>
Here can be found me question in stackoverflow.
