Login with curl and move to another page

Question

I\'m trying to access one page in a website with CURL, however it needs to be logged in i tried the code to login and it was successful

Answer 1

First define these function to get an associative array containing the url header and content (see http://nadeausoftware.com/articles/2007/06/php_tip_how_get_web_page_using_curl):

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url, $params, $is_post = true )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "Mozilla/4.0 (compatible;)", // i'm mozilla
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    );

    if($is_post) { //use POST

        $options[CURLOPT_POST] = 1;
        $options[CURLOPT_POSTFIELDS] = http_build_query($params);

    } else { //use GET

        $url = $url.'?'.http_build_query($params);

    }

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

try this to load the 'http://www.example.com/buy' after login is successful.

// after curl login setup
$exec = curl_exec($curl_crack);
if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
{
    // close login CURL resource, and free up system resources
    curl_close($curl_crack);

    $params = array('product_id'=>'xxxx', qty=>10);
    $url = 'http://www.example.com/buy';

    //use above function to get the url content via POST params
    $result = get_web_page($url, $params, true);

    if($result['http_code'] == 200) {
        //echo the content
        echo $result['content'];
        die();
    }
}

If you want to go to /buy after you log in, just use the same curl handle and issue another request for that page. cURL will retain the cookies for the duration of the handle (and on subsequent requests since you are saving them to a file and reading them back with the cookie jar.

For example:

$user_agent       = "Mozilla/5.0 (X11; Linux i686; rv:24.0) Gecko/20140319 Firefox/24.0 Iceweasel/24.4.0";
$curl_crack = curl_init();

CURL_SETOPT($curl_crack,CURLOPT_URL,"https://www.vininspect.com/en/account/login");
CURL_SETOPT($curl_crack,CURLOPT_USERAGENT,$user_agent);
CURL_SETOPT($curl_crack,CURLOPT_PROXY,"183.78.169.60:37899");
CURL_SETOPT($curl_crack,CURLOPT_PROXYTYPE,CURLPROXY_SOCKS5);
CURL_SETOPT($curl_crack,CURLOPT_POST,True);
CURL_SETOPT($curl_crack,CURLOPT_POSTFIELDS,"LoginForm[email]=naceriwalid%40hotmail.com&LoginForm[password]=passwordhere&toploginform[rememberme]=0&yt1=&toploginform[rememberme]=0");
CURL_SETOPT($curl_crack,CURLOPT_RETURNTRANSFER,True);
CURL_SETOPT($curl_crack,CURLOPT_FOLLOWLOCATION,True);
CURL_SETOPT($curl_crack,CURLOPT_COOKIEFILE,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
CURL_SETOPT($curl_crack,CURLOPT_COOKIEJAR,"cookie.txt"); //Put the full path of the cookie file if you want it to write on it
CURL_SETOPT($curl_crack,CURLOPT_CONNECTTIMEOUT,30);
CURL_SETOPT($curl_crack,CURLOPT_TIMEOUT,30);  

$exec = curl_exec($curl_crack);
if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
{
    $post = array('search' => 'keyword', 'abc' => 'xyz');

    curl_setopt($curl_crack, CURLOPT_POST, 1); // change back to GET
    curl_setopt($curl_crack, CURLOPT_POSTFIELDS, http_build_query($post)); // set post data
    curl_setopt($curl_crack, CURLOPT_URL, 'http://example.com/buy'); // set url for next request

    $exec = curl_exec($curl_crack); // make request to buy on the same handle with the current login session
}

You just need to change the URL after login is compete and then run curl_exec Like this :

<?php

//login code goes here

if(preg_match("/^you are logged|logout|successfully logged$/i",$exec))
{
    echo "Logged in! now lets go to other page while we are logged in, shall we?";
    //The new URL that you want to go to while logged in goes in bottom line :
    CURL_SETOPT($curl_crack, CURLOPT_URL, "https://new_url_to_go.com/something");
    $exec = curl_exec($curl_crack);
    // now $exec contains the the content of new page with login
} 


curl_close($curl_crack);//dont forgert to close curl session at last
?>
