RE: Having problem sending XML over HTTP

["Nauman Akbar" <nauman@xxxxxxxxxxxxxxxxxxxx>]

Hello!

Thanx for reminding me that I can use a regular POST as well rather then
sending XML over HTTP directly :). Perhaps I was quite tired by then.

Anyways I tried that. Unfortunately, it seems POST data is not getting
through at all. I sent the same query with GET and it is returned fine. But
var_dump on both $_POST and $HTTP_RAW_POST_DATA return empty strings even
with a regular POST with Curl. Yes the data is urlencoded.

My server is RHEL4 with Plesk 8.x. I got PHP upgraded to PHP 5 yesterday. I
know POST requests are working fine through browser. I have tried Opera and
IE and both work just fine. So my guess is; it is probably curl causing the
problem. Can someone point me to some resource or documentation on this
issue?

Regards,
Nauman Akbar

Try this:

--------------------------------
The code for the sending script:

<?php
$xmlstr =
"<query><username>fff-bbbb</username><password>alphanumeric</password><funct
ion>GetPackageVersion</function></query>";

$ch=curl_init(); 
curl_setopt($ch, CURLOPT_URL, "http://example.com/your-accepting-page.php";);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, "xmlstr=".urlencode($xmlstr)); 
curl_setopt($ch, CURLOPT_TIMEOUT, 120); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$buffer = curl_exec($ch); 
curl_close($ch);

print_r($buffer);
?>

----------------------------------
The code for the receiving script:

<?php

if(!empty($_POST)) {
	echo "You sent me some data... here is what I received:\n";
	print_r($_POST);
}

?>

Then open a browser and surf to the sending script.  It should print the
response from the receiving page.

Here is the output:

You sent me some data... here is what I received:
Array
(
    [xmlstr] =>
<query><username>fff-bbbb</username><password>alphanumeric</password><functi
on>GetPackageVersion</function></query>
)

I tested this and its working (at least on my server).

Sorry I don't have the time to tell you what is wrong with your code but
it's easier for me to just provide something that works.

I hope that helps you,

Brad
