Question

I’m trying to send by POST method a XML through of CURL to authenticated webServices, but for some reason the server is rejecting the XML file, me giving me an error 500, however another WebService than by GET method, not have problem. The following code is i’m trying.

  <?php
  $request_xml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?> 
  <FiltroLicitaciones xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"> 
  <CantidadRegistro>10</CantidadRegistro> 
  <Texto>memo</Texto> 
  <CodigoRegion xsi:nil=\"true\" /> 
  <CodigoEstado>1</CodigoEstado> 
  <TipoFecha>FechaPublicacion</TipoFecha> 
  <FechaDesde>2011-06-01T00:00:00</FechaDesde> 
  <FechaHasta>2011-08-01T00:00:00</FechaHasta> 
  </FiltroLicitaciones>";

  //Initialize handle and set options 
  $username = 'user'; 
  $password = 'pass'; 
  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, 'https://www.mercadopublico.cl/movil/licitaciones/porFecha');  
 //curl_setopt($ch, CURLOPT_URL, "http://localhost/server.php"); 
   curl_setopt($ch, CURLOPT_USERPWD, $username.':'.$password); 
   curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true); 
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
   curl_setopt($ch, CURLOPT_HEADER, 1); 
   curl_setopt($ch, CURLOPT_TIMEOUT, 4); 
   curl_setopt($ch, CURLOPT_POSTFIELDS, $request_xml);

   $result = curl_exec($ch); 

   curl_close($ch); 

   print_r($result); 

   ?>

I don’t know if will be a error for XML malformed, but server return me a random 500 error with the following header:

HTTP/1.1 500 The server encountered an error processing the request. Please see the      server logs for more details.

I did a test in the local server, for see as the data came, the following the result this is:

I hope can you help me.

Answer 1

Well I’m not sure if the 500 error is from the xml but, as I see in your code the xml has no url variable :

  myxml=<xml></xml>

Because as you can see from the response the url paramenter has become

 [<?xml version] => "1.0" encoding="utf-8" ?> 

and this is wrong.

If the api docs didn’t specified any url parameters then you should probably set the right curl header :

 curl_setopt($ch,CURLOPT_HTTPHEADER, Array("Content-Type: application/xml"); 

Like this the server knows what to expect
