I have a script that sends data to and gets a response from a web service. The response is a link/url that will be used to check the registration status. I use file_get_contents to get the status from the provided url. After getting the status, the user is then redirected into a page. The registration process will take up to 10 seconds to complete so I need to check the registration status again using the provided url/link.
PHP does not allow to header location redirects so what I did was I used jQuery and AJAX to check for the registration status. It works when the page is not yet redirected. But in this case, it won't work since the page redirects first to another URL before checking the registration status after 10 seconds.
I hope this isn't confusing.
Here's the code I use:
<?php
function sendRequest($url, $params)
{
$request = curl_init($url); // initiate curl object
curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response
curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
curl_setopt($request, CURLOPT_POSTFIELDS, $params); // use HTTP POST to send form data
curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment this line if you get no gateway response.
$response = curl_exec($request); // execute curl post and store results in $post_response
curl_close ($request); // close curl object
return $response;
}
function sendJSONRequest($url, $data)
{
$data_string = json_encode($data);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT ,50);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Accept: application/json',
'X-MP-Version: 10072013')
);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
ob_start();
$result = curl_exec($ch);
$info = curl_getinfo($ch);
if ($result === false || $info['http_code'] == 400) {
return "0";
} else {
return $result;
}
ob_end_clean();
curl_close($ch);
}
function WriteLog($offer,$values)
{
$Filename = "./reports/".$offer.date('Ym').".txt";
$fh = fopen($Filename, 'a') or die("can't open file");
$filecontent = date('Y-m-d G:i').',';
$filecontent .= $values;
$filecontent .= PHP_EOL;
fwrite($fh,$filecontent);
fclose($fh);

If you have suggestions on how I could accomplish this, I would be very grateful. Thanks.
