PHP, Curl, and Http Post Example

PHP, cURL, and HTTP POST example?

<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "postvar1=value1&postvar2=value2&postvar3=value3");

// In real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS, 
//          http_build_query(array('postvar1' => 'value1')));

// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

curl_close ($ch);

// Further processing ...
if ($server_output == "OK") { ... } else { ... }
?>

PHP/CURL - Making a POST request to another page and following the URL

How about this? It assumes name, amount and email will be posted to process.php

Added trouble shooting code.

process.php

 <?php

 //[put database queries here]

 // $message = ??????????????????


$message = 'Message';

$post = array(
'name'=>$_POST['name'],
'amount'=>$_POST['amount'],
'email'=>$_POST['email'],
'message'=>$message);

$ch = curl_init('http://www.example.com/display.php');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_ENCODING,"");

header('Content-Type: text/html');
$data = curl_exec($ch);
echo $data;
?>

This was tested and works too

does the redirect to the actual site.

<?php
$name = $_POST["name"];
$amount = $_POST["amount"];
$email = $_POST["email"];
$message = $_POST["message"];

echo <<< EOT
<html><head><style></style></head><body>
<form id="form" action="http://www.example.com/display.php" method="post">
<input type="hidden" name="name" value="$name"/>
<input type="hidden" name="amount" value="$amount"/>
<input type="hidden" name="email" value="$email"/>
<input type="hidden" name="message" value="$message"/>
</form>

<script>document.getElementById("form").submit();</script>
</body></html>
EOT;

?>

php curl post request and get result response

The very first: I'm using Firebug add-on and see what happen

enter image description here
Here one ajax get content from other site

We have this link

https://apis.pos.com.my/apigateway/as2corporate/api/v2trackntracewebapijson/v1/?id=EP024922993MY&Culture=En

In request of header we can see require X-User-Key

enter image description here

Now we must find X-User-Key => We can view source

enter image description here

Now we build source code

<?php
function _curl($url,$post="",$usecookie = false,$_sock = false,$timeout = false,$x_user_key = false) {  
    $ch = curl_init();
    if($post) {
        curl_setopt($ch, CURLOPT_POST ,1);
        curl_setopt ($ch, CURLOPT_POSTFIELDS, $post);
    }
    if($timeout){
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,$timeout);
    }
    if($_sock){
            curl_setopt($ch, CURLOPT_PROXY, $_sock);
            curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
    }
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Version/4.0 Mobile/7A341 Safari/528.16");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'X-Apple-Tz: 0',
    'X-Apple-Store-Front: 143444,12'
    ));
    if($x_user_key){
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'X-User-Key: '.$x_user_key,
        'Referer: http://poslaju.com.my/track-trace/',
        'Origin: http://poslaju.com.my'
        ));
    }
    if ($usecookie) { 
        curl_setopt($ch, CURLOPT_COOKIEJAR, $usecookie); 
        curl_setopt($ch, CURLOPT_COOKIEFILE, $usecookie);    
    }
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
    $result=curl_exec ($ch); 
    curl_close ($ch); 
    return $result; 
}
function getStr($string,$start,$end){
    $str = explode($start,$string,2);
    $str = explode($end,$str[1],2);
    return $str[0];
}
$url = 'http://poslaju.com.my/track-trace/';
$result_curl = _curl($url,'','','','','');
$x_user_key = getStr($result_curl,'{ "X-User-Key": "','" }');

$id_track = 'EP024922993MY';
$url = 'https://apis.pos.com.my/apigateway/as2corporate/api/v2trackntracewebapijson/v1/?id='.$id_track.'&Culture=En';
$result_curl = _curl($url,'','','','',$x_user_key);
echo $result_curl;
?>

Change id on your mind

You can get json content

Use print_r(json_decode($content_you_got)

And result you will have like this

Execute a HTTP POST Using PHP CURL

Managed to work out an answer to my question

<?php
$endpointUser = "mylogin";
//
$endpointPassword = "mypass";
//
$url = "https://dataurl.com";

$iframeUrl =  "https://myurl.com?token=";

$fields = array(
    "User.IdentityNumber"=> $_GET['security_phrase'] ,
    "CapeConsumers.TrackerNumber"=> "6E273247DB4840G3",
    "Call.AgentReference"=> $_GET['user'] ,
    "Call.RecordingReference"=> $_GET['security_phrase']
);

$process = curl_init($url);
curl_setopt($process, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($process, CURLOPT_HEADER, 0);
curl_setopt($process, CURLOPT_USERPWD, $endpointUser . ":" . $endpointPassword);
curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_POST, 1);
curl_setopt($process, CURLOPT_POSTFIELDS, json_encode($fields));
curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
$token = curl_exec($process);
curl_close($process);
$token = str_replace('"','',$token);


?>


<iframe src="<?php echo $iframeUrl . $token; ?>" width="100%" height="800"></iframe>

I will leave the question unedited so that anybody else can have a look at how it was done if needed

How to do a PHP curl post

// init curl

$handle = curl_init();

// set options/parameters

curl_setopt( $handle, CURLOPT_URL,              'https://developer.lametric.c...');
curl_setopt( $handle, CURLOPT_CUSTOMREQUEST,    "POST");
curl_setopt( $handle, CURLOPT_POSTFIELDS,       'the-json-encoded-data-here' );
curl_setopt( $handle, CURLOPT_RETURNTRANSFER,   true ); // you want to get the response

// set headers 

curl_setopt( $handle, CURLOPT_HTTPHEADER,       array(  'Accept: application/json',
                                                        '....' ) );
// execute the request and get the response

$response = curl_exec( $handle );

// get the status too

$status = curl_getinfo( $handle, CURLINFO_HTTP_CODE );

// release resources

curl_close( $handle );

Just an example/introduction.

You initialize php's curl.

Setup all the parameters.

Send the request.

I won't write all the code for you.

PHP Reference is clear (and have examples too)

http://php.net/manual/en/book.curl.php

SO have examples too:

PHP + curl, HTTP POST sample code?

How can I use cURL to post form data in php?

since no answer got it right thus far (at least not with an approach that would work in php 5.6+), here goes: the equivalent php curl_ code would be:

$ch = curl_init ( 'https://apiprovider.com/api/v0/imports?token=[KEY]' );
curl_setopt_array ( $ch, array (
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => array (
                'file' => new CURLFile ( '/home/USERNAME/import.csv' ) 
        ) 
) );
curl_exec ( $ch );

(i would also recommend setting CURLOPT_ENCODING to emptystring, especially if you expect the response to be compressible, that would be the equivalent of adding --compressed to the curl command line, and might speed things up)
