I am trying to post form data from www.siteone.com to www.sitetwo.com via CORS. My ajax code is this:
<script>
$(document).ready(function(){
$("#submit").live('click',function() {
var url = "http://www.sitetwo.com/cors.php";
var data = $('#form').serialize();
jQuery.ajax({
url : url,
type: "POST",
data : $('#form').serialize(),
}).done(function(response){
alert(response);
}).fail(function(error){
console.log(error.statusText);
});
return false;
});
});
</script>
and the file cors.php in www.sitetwo.com
is as follows:
<?php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
echo "hai";
?>
But still Access-control-Allow-Origin error is thrown. The error thrown is this:
XMLHttpRequest cannot load http://www.sitetwo.com/cors.php. Origin http://www.siteone.com is not allowed by Access-Control-Allow-Origin.
I came to know that, using CORS by just allowing the remote website via headers, we can use cross-domain request. But when I tried like this, error is thrown. Have I missed anything in here? Here is my request/response headers:
Response Headers
Connection Keep-Alive
Content-Length 487
Content-Type text/html; charset=iso-8859-1
Date Fri, 23 Aug 2013 05:53:20 GMT
Keep-Alive timeout=15, max=99

WWW-Authenticate Basic realm="Site two Server - Restricted Area"
Request Headers

Content-Length 43
Content-Type application/x-www-form-urlencoded; charset=UTF-8
Host www.sitetwo.com

User-Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:23.0) Gecko/20100101 Firefox/23.0
Finally, I myself have solved the problem explained in the question. The code that I have implemented for accessing header is incorrect.
The below mentioned two line code, when given, didn't work:
<?php
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS');
?>
But handling CORS requests properly is a tad more involved. Here is a function that will respond more fully. The updated code is this :
<?php
// Allow from any origin
if (isset($_SERVER['HTTP_ORIGIN'])) {
header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Max-Age: 86400'); // cache for 1 day
}
// Access-Control headers are received during OPTIONS requests
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
header("Access-Control-Allow-Headers: {$_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']}");
exit(0);
}
echo "You have CORS!";
?>
I have found from another post It worked....
