Actually it is more general question but now i am trying to use it on wordpress site so I preferred to post it here.

I am trying to understand the difference between remote post and form post.

When I query a string and post it to remote server, I get the result as string and with "print $response" see it on browser console. But I want it to be displayed as html on browser. Am I expecting wrong thing or could i do such thing?

Basically I want to see raw response as html.

EDIT

In case of being more expressive.. I am trying to write credit card payment gateway inside woocommerce

Inside process_payment function which is called at the end of customer order, I am posting all info to bank server like below:

public function process_payment( $order_id ) {
    global $woocommerce;
    ....
    ...
    $okUrl = "http://localhost/xxx/wc-api/paymentpos/";         
    $failUrl = "http://localhost/xxx/wc-api/paymentpos/";
    $payload = array(.....);
         $response = wp_remote_post( $environment_url, array(
        'method'    = 'POST',
        'body'      = http_build_query( $payload ),
        'timeout'   = 45,
        'sslverify' = false,
    ) );
    $respbody = wp_remote_retrieve_body($response);
    print $respbody;
    }

After that, bank server should reply to payment_callback() which is like

public function payment_callback(){

    global $woocommerce;

    wc_add_notice( 'OK', 'success' );
    .....
    exit();     
}

I am getting $respbody as below on console.

!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
html
head
META http-equiv="Content-Type" content="text/html; charset=UTF-8"
script type="text/javascript" language="javascript"
function moveWindow() {
  document.returnform.submit();
}
/script  
/head

body onLoad="javascript:moveWindow()"
form action="http://localhost/xxx/wc-api/paymentpos/" method="post" name="returnform"

 input type="hidden" name="EXTRA.ERTELEMESABITTARIH" value="20121123"
 ....
 input type="hidden" name="okUrl" value="http://localhost/xxx/wc-api/paymentpos/"
 ...
 input type="hidden" name="mdStatus" value="2"

 ...    

    !-- To support javascript unaware/disabled browsers --
    noscript
        centerbr
        Please Click to continue.br
        input type="submit" name="submit" value="Submit" id="btnSbmt"/center
    /noscript 
/form
/body
/html
{"result":"failure","messages":"","refresh":"false","reload":"false"}

This response should trigger payment_callback() function. Manually I could trigger payment_callback() like http://localhost/xxx/wc-api/paymentpos/. But this response could not trigger. I am suspicious about I could handle wp_remote_post response correctly.

The difference is that you have more control over the arguments you use in wp_remote_post. But because you have more control, the defaults won't always be the same. For example; User Agent is usually empty with wp_remote_post but uses the browser name when submitting the form in your browser.

When you consume a POST request there isn't much difference. It's typically just the $_GET or $_POST ($_REQUEST for either) on the other end that holds key value pairs.

wp_remote_get returns a json string.

You have different function to work with this json response. wp_remote_head() wp_remote_retrieve_body(), wp_remote_retrieve_header(), wp_remote_retrieve_headers(), wp_remote_retrieve_response_code(), wp_remote_retrieve_response_message()

The example from the codex:

$response = wp_remote_get( 'http://www.example.com/index.html' );
  if( is_array($response) ) {
     $header = $response['headers']; // array of http header lines
     $body = $response['body']; // use the content
 }

Depending on the page request, the body could be an array or object or HTML. Of course, in case of array or object, there's a need to loop through the results like usually.

Hope it helps
