How to post XML using CURL?

49 Replies

Recently I was working in a hotel booking engine and found a couple of methods to post XML to server; I thought this might be good to share with my friends who want to post xml via HTTP POST method.

There are several ways to Send XML requests via HTTP POST.
I am going to show you two ways. Both are very simple and easy.

As first approach I have used a small xml file with CURL.


'.
    ''.
        '1234567890'.
        'lgsoftwares'.
        'mypassword'.
        'phpmind.com'.
    ''.
    ''.
        ''.
        ''.
    ''.
''.
'JHM'.
        'OGGSHE'.
        '101009'.
        '101509'.
        '1'.
  ''.  
  '';


$URL = "https://www.yourwebserver.com/path/";

			$ch = curl_init($URL);
			curl_setopt($ch, CURLOPT_MUTE, 1);
			curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
			curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
			curl_setopt($ch, CURLOPT_POST, 1);
			curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
			curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml_data");
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
			$output = curl_exec($ch);
			curl_close($ch);

?>

    Invaluable suggestions ! I loved the details – Does anyone know if I can find a template SSA-632-BK. form to work with ?

    Can this code be used with any of the software we are developing or changes need to be done in it?

    I’m not sure exactly why but this blog is loading incredibly slow for me.
    Is anyone else having this issue or is it a issue on my end?
    I’ll check back later and see if the problem still exists.

    I found the code useful. It worked great but after changing this line curl_setopt($ch, CURLOPT_MUTE, 1); to
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    As the provious function was depreciated.

    Good afternoon guys, I tried to implement this example and came across the following message: 411 Length Required.

    My example, gotta send via PUT, follows my code below:

    Thank you so much. I was struggling with this from last couple of days. Today I found your post and it worked in first go. Thanks 🙂 I was also trying to do it with jQuery+Ajax. Can this be done using jquery?

    Hi Guys, I’m trying this code but it doesn’t work for me, I need make a PUT request with XML data in body.

    I have try this by command line

    curl -v -X PUT -d ‘129029Adding notes to URL MMMMMMMM 562000000000’ -H ‘Content-Type: application/xml’ ‘https://service.com/api/’

    And works great, but I try this by php and it doesn’t

    $xml_data = ‘129029Adding notes to URL MMMMMMMM 3000000’;
    $URL = “https://service.com/api/”;

    $ch = curl_init($URL);
    curl_setopt($ch, CURLOPT_PUT, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type: application/xml’));

    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);
    $output = curl_exec($ch);
    var_dump($output);
    curl_close($ch);

    And this way I’m getting this error:

    411 Length Required

    What do you think I’m doing wrong.

    Thanks a lot

    Hi,
    I send request in xml format. I can get the response when i execute in localhost and if it is in web server it shows

    “cURL Error (7): couldn’t connect to host”
    Here’s my code

    function xml_post($post_xml, $url)
    {
    $user_agent = $_SERVER[‘HTTP_USER_AGENT’];

    $ch = curl_init(); // initialize curl handle
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_URL, $url); // set url to post to
    curl_setopt($ch, CURLOPT_FAILONERROR, 1); // Fail on errors
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // allow redirects
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
    curl_setopt($ch, CURLOPT_TIMEOUT, 50); // times out after 15s
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_xml); // add POST fields
    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
    // curl_setopt($ch, CURLOPT_PORT, $port); //Set the port number

    $data = curl_exec($ch);
    $curl_errno = curl_errno($ch);
    $curl_error = curl_error($ch);

    curl_close($ch);
    if ($curl_errno > 0) {
    echo “cURL Error ($curl_errno): $curl_error\n”;
    } else {
    echo “Data received\n”;
    }
    //print_r($data);
    echo $data;
    }
    ?>
    What may be the problem?

    Hi,
    I am using this script and its working fine. but I am facing one issue only when the size of xml increases, it throws the following error.

    /**************************************************************/
    ERROR
    The requested URL could not be retrieved

    While trying to process the request:

    POST /servlet/ExternalServiceRequestServlet HTTP/1.1
    Host: qa1.servicemagic.com

    Thanks for your patient replies once again….

    actually my end goal is to post an XML to a site, but what should me my changes in this case?

    and yes to view the response i have this file server.php

    $xml = file_get_contents(‘client.php’);
    $xml = new SimpleXMLElement($xml, LIBXML_NOCDATA, false);

    $response = (string) $xml;
    $response = strtoupper($response);

    echo $response;

  35. om Post author

    you are not sending XML file. while you are using Content-Type: text/xml

    Where you want to send xml file?

  36. mandm

    ok so i just tried this and when i execute php client.php, it returns

    it does not return “Testing” back
    ???

    <?php

    $xml = 'Testing’;
    $server = ‘server.php’; // URL to server.php

    $ch = curl_init($server);
    curl_setopt($ch, CURLOPT_MUTE, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, “$xml”);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type: text/xml’));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);
    curl_close($ch);

    echo ”, simplexml_load_string($response), ”;

    yes curl is enabled on my server and how do i check if the any response is coming back ?

  41. om Post author

    First do one thing. Try a to Execute a small CURL code in your server. There are tones of examples over internet and make sure that CURL is enabled in your server. You can check using phpinfo().

    Do you know, if there is any response come back in your case when you send XML request using CURL?

  42. mandm

    can you tell me how i could get the action url to return something on the screen ?

    another thing i just noticed, so i thought i might ask you, i have seen my php is becoming very slow and unresponsive while trying out all these curl options? any guesses

  43. om Post author

    i think this will not show you any output until your action url return something. You can check CURL status only if it is true or false by running that code.

  44. mandm

    Hi om,
    Thanks for your reply, i will definatey try to exclude the
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

    lines from the file

    but i have few more questions that some forums say that the curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type: text/xml’));
    should be after

    curl_setopt($ch, CURLOPT_POSTFIELDS, “$xml_data”);

    guessing something to do with the XML header part

    another questions was more of a concept clearing one…

    so suppose i have this name this file as client.php and paste all you script in it (excluding the SSL part) then once i run the script client.php from the webserver should i expect the data to show up in the

    http://www.yourwebserver.com/path/

    or do i have to script something to be able to receive this data
    ?

    making this a client-server model

    thanks again for your response

  45. om Post author

    I have used SSL you don’t have to use if your server does not support. Send your XML normally without SSL. like this. And let me know. In my case i am using SSL so i had given that example and its working for me!! Second thing is check your “CURL lib” with any simple example.

    $ch = curl_init($URL);
    curl_setopt($ch, CURLOPT_MUTE, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(‘Content-Type: text/xml’));
    curl_setopt($ch, CURLOPT_POSTFIELDS, “$xml_data”);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($ch);
    curl_close($ch);

    This does not work for me?
    what i have done is copied this file exactly on my webserver and executed it by calling php new2.php

    and i am expecting the results to show up in my URL http://www.example.com/post2.php

    do i need to add something in the post2.php as well?
