通过CURL发布XML文件而不是访问网址

Question

While I am posting XML content from one server to other server, it is not getting added. I'm using cURL to post the xml files to another server. But I am getting the following response:

HTTP/1.1 200 OK
Date: Thu, 21 Jul 2011 08:13:02 GMT
Server: Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.6 with Suhosin-Patch mod_ssl/2.2.8 OpenSSL/0.9.8g

Pragma: no-cache

This is my code

$file_path= WWW_ROOT.$xmlfilename;          
$xmldata = file_get_contents($file_path);
$request = 'http://www.sample.com/someaction';
$postargs = 'xml='.urlencode($xmldata).'&filename='.urlencode($xmlfilename);

// Get the curl session object
$session = curl_init($request);

// Set the POST options.
curl_setopt($session, CURLOPT_POST, true);
curl_setopt($session, CURLOPT_POSTFIELDS, $postargs);
curl_setopt($session, CURLOPT_HEADER, true);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// Do the POST and then close the session
$response = curl_exec($session);
print_r( $response);

Note: allow_url_fopen and curl are enabled in both servers.

Answer 1

Try assigning it like this:

$postargs = array('xml' => urlencode($xmldata), 'filename' => urlencode($xmlfilename))

Both items should then appear in $_POST['xml'] and $_POST['filename'] in the receiving side (or equivalent if not PHP).

EDIT

OK you may need to look at streaming the XML file using CURLOPT_READFUNCTION.

See this for a bit of an example http://zingaburga.com/2011/02/streaming-post-data-through-php-curl-using-curlopt_readfunction/
