If you try to do an ajax request on a different domain. You’ll get nothing. Looking a bit deeper into the request I noticed that the status code isn’t 200 or 403 nor 404 like expected. Nope it is 0. (jquery ajax statusCode 0). This means the browser doesn’t allow a crossdomain request. The easiest way for me to solve this was to create a proxy php script. Now I can send my ajax request to a url on my server while the PHP script does the real request to the other server.
This is the php script
/**
* GetFromHost()
*
* @param string $host
* @param int $port
* @param string $path
* @param string $referer
* @param bool $keepalive
* @return
*/
function GetFromHost($host, $port, $path, $referer,$keepalive=false) {
$fsocket = fsockopen($host, 80, $errno, $errstr, 30);
if($fsocket){
$request = "GET $path HTTP/1.1\r\n";
$request .= "Host: $host\r\n";
$request .= "Referer: $referer\r\n";
$request .= 'User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) ';
$request .= "Gecko/20021204\r\n";
$request .= 'Accept: text/xml,application/xml,application/xhtml+xml,';
$request .= 'text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,';
$request .= "image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1\r\n";
$request .= "Accept-Language: en-us, en;q=0.50\r\n";
//$request .= "Accept-Encoding: gzip, deflate, compress;q=0.9\r\n";
$request .= "Accept-Charset: ISO-8859-1, utf-8;q=0.66, *;q=0.66\r\n";
if($keepalive==true){
$request .= "Keep-Alive: 300\r\n";
$request .= "Connection: keep-alive\r\n";
}
else
{
$request .= "Connection: close\r\n";
}
//$request .= "Content-Type: application/x-www-form-urlencoded\r\n";
//$request .= "Content-length: ". strlen($data_to_send) ."\r\n";
$request .= "\r\n";
//$request .= $data_to_send;
fputs($fsocket, $request);
$res ='';
while(!feof($fsocket)) {
$res .= fgets($fsocket, 1024);
}
fclose($fsocket);
return $res;
}
else
{
return false;
//echo "Fehlgeschlagen: ".$fsocket . $host .':'. $port;
}
}
$x = GetFromHost("www.example", "80", "/deep/url/kinda/", "");
$x = explode('Content-Type: text/html',$x);
$output = preg_replace('/\s+(\r\n|\r|\n)/', '$1', $x['1']);//remove white space and tabs at the line ends
echo $output;maybe you have to edit the explode part for server to separate the header fom the real content.
