用PHP cURL发布数据

Question

I want to show my problem and I hope to find a solution I have this website to generate IPTV accounts http://iptv.alkaicerteams.com/iptv/index.php This site contains several passwords that are randomly exchanged by the short link above The password is confirmed by the short link

The site then sends the password to the following link to generate an account http://iptv.alkaicerteams.com/iptv/post.php And it has asked the head

POST /iptv/post.php HTTP/1.1

You have typed a code that identifies the short link and identifies the password http://iptv.alkaicerteams.com/iptv/index.php And then send the data to http://iptv.alkaicerteams.com/iptv/post.php But the response comes

What is the problem with my code

<?php

$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL,'http://iptv.alkaicerteams.com/iptv/index.php');
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
$query = curl_exec($curl_handle);
curl_close($curl_handle);
$lines = explode("
", $query);
$shotline= $lines[257];
$shotline = preg_replace('/\s+/', '', $shotline);

preg_match('/(http:\/\/[^\s]+)/', $shotline, $text);
$solit_shor_url =($text[0]); 
$end_short_url = substr($solit_shor_url, 0, 19);

$pass ='';

if ($end_short_url=='http://gsul.me/e4uM') {
    $pass ='user=2224248965317031';

} 

//echo 'url: '.$end_short_url ;
//echo 'pass: '.$pass ;


$url = 'http://iptv.alkaicerteams.com/iptv/post.php';
//$ID = $_GET['id'];
//pass = http://iptv.alkaicerteams.com/iptv/
$data = $pass ;
$options = array(
  'http' => array(
   'header'  => "Content-type: application/x-www-form-urlencoded
", 
   "Origin: http://iptv.alkaicerteams.com",
   'method'  => 'POST',
    'content' => $data,
  ),
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);


//$XX= $json_a['username'];
echo $result ;

Answer 1

The problem is that the PHP backend on the second request to /iptv/post.php expects the user to be authenticated, i.e. him to send auth cookie he obtained on the first request. In order to do that you can use CURLOPT_COOKIEJAR and CURLOPT_COOKIEFILE cURL options and save/retrieve cookies from a temporary file placed in /tmp folder.

You can also update your code to not parse the HTML output and remove hardcoded 257 line. Even though it's better to address the elements of an HTML tree using DOM, since you need just the short URL you can use PCRE here.

Also, please rewrite your if/elseif/else code into switch/case if there is no other option to put this all into a hashtable to a config or a database.

So this code works fine:

$cookies = tempnam('/tmp','cookie.txt');

$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL,'http://iptv.alkaicerteams.com/iptv/index.php');
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_handle, CURLOPT_COOKIEJAR, $cookies);
curl_setopt($curl_handle, CURLOPT_COOKIEFILE, $cookies);
$response = curl_exec($curl_handle);

$matches = [];
preg_match('/\'(http:\/\/gsul\.me\/[a-zA-Z0-9]*?)\'/', $response, $matches);
curl_close($curl_handle);

$end_short_url = $matches[1];

switch($end_short_url) {
    case 'http://gsul.me/e4uM':
        $pass = 'user=2224248965317031';
        break;
    case 'http://gsul.me/e4uT':
        $pass = 'user=1120135520184221';
        break;
    case 'http://gsul.me/e4uX':
        $pass = 'user=9999600017456111';
        break;
    case 'http://gsul.me/e4v0':
        $pass = 'user=9441513141365431';
        break;
    case 'http://gsul.me/e4un':
        $pass = 'user=3354872122101111';
        break;
    case 'http://gsul.me/e4uw':
        $pass = 'user=798460044567891';
        break;
    case 'http://gsul.me/e4us':
        $pass = 'user=7513000478963541';
        break;
    case 'http://gsul.me/e4vc':
        $pass = 'user=4242421596324581';
        break;
    case 'http://gsul.me/e4uo':
        $pass = 'user=7531596542584301';
        break;
    case 'http://gsul.me/e4uG':
        $pass = 'user=5303306289156271';
        break;
    default:
        $pass ='erorr';
        break;
}


$curl_handle=curl_init();
curl_setopt($curl_handle, CURLOPT_URL,'http://iptv.alkaicerteams.com/iptv/post.php');
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_handle, CURLOPT_COOKIEJAR, $cookies);
curl_setopt($curl_handle, CURLOPT_COOKIEFILE, $cookies);
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, $pass);
$response = curl_exec($curl_handle);
curl_close($curl_handle);

var_dump($response);
