Re: HTTP_RAW_POST_DATA Strangeness

Hi Scott,

  I understand what you wrote, but I still don't understand why this works:

  $HTTP_RAW_POST_DATA = @$HTTP_RAW_POST_DATA ? $HTTP_RAW_POST_DATA : $_POST;
  $server->service($HTTP_RAW_POST_DATA);

and this doesn't (since $HTTP_RAW_POST_DATA is undefined):

  $server->service($_POST);

You are correct: service($data) does not care where the $data comes 
from.  That means, for instance, that it is possible to write a test 
harness that calls service with $data read from a file.

For an HTTP GET, service ignores $data and returns the WSDL or the 
documentation page.  For an HTTP POST, service assumes it is handling a 
SOAP call, so $data must be a SOAP envelope.  It is your job to provide 
service with that SOAP envelope.  Normally, the body of the HTTP POST is 
the envelope, which is why programmers typically use 
$HTTP_RAW_POST_DATA.  If your PHP configuration prevents you from using 
$HTTP_RAW_POST_DATA, you must find an alternative way to get the data that 
service needs.

If you are using PHP 4.3.0 or later, you can use the php://input stream.

Subject: [Nusoap-general] HTTP_RAW_POST_DATA Strangeness


Hello,

   I am having a strange problem that seems to be based on a setting in
php.ini: always_populate_raw_post_data=On vs Off

   If this value is not set to On (which I have no control over at a shared
hosting server) the following code will produce a valid WSDL, but when the
service is called it faults with 'xml was empty, didn't parse'.

Works if always_populate_raw_post_data=On:
   $server->service($HTTP_RAW_POST_DATA);

Generates correct WSDL for service.php?wsdl:
   $server->service($_POST);  // generates above fault when called though

Only way it works with =Off:
   $HTTP_RAW_POST_DATA = @$HTTP_RAW_POST_DATA ? $HTTP_RAW_POST_DATA : $_POST;
   $server->service($HTTP_RAW_POST_DATA);

   I can't see where the service($data) would care where the $data came
from in nusoap.php (nor anywhere else $HTTP_RAW_POST_DATA is referenced).

This is with latest CVS nusoap.php v 1.72,
   John
