问题:

I've been experimenting over and over but what I've got so far doesn't allow me to login into Pinterest with CURL and I cannot understand why..

function pinLogin()
{   
    $login_post     = array(
        'source_url' => '/login/',
        'data' => '{
            "options":{
                "username_or_email":"email",
                "password":"password"
                },
            "context":{}}',
        'module_path' => 'App()>LoginPage()>Login()>Button(text=Log In, size=large, class_name=primary, type=submit)',
    );

    $httpheaders    = array(
       'Connection: keep-alive',
       'Pragma: no-cache',
       'Cache-Control: no-cache',
       'Content-Type: application/x-www-form-urlencoded; charset=UTF-8',
       'User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0',
       'Accept: application/json, text/javascript, */*; q=0.01',
       'Accept-Language: en-US,en;q=0.5',
       'Accept-Encoding: gzip, deflate',
    );

    $login_header   = array(
        'X-Pinterest-AppState: active',
        'X-NEW-APP: 1',
        'X-APP-VERSION: 71854ca',
        'X-Requested-With: XMLHttpRequest',
        'Accept: application/json, text/javascript, */*; q=0.01'
    );

    // request home page to establish cookies and a session, set curl options
        $ch = curl_init('http://www.pinterest.com/');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

        curl_setopt($ch, CURLOPT_VERBOSE, 1);
        curl_setopt($ch, CURLOPT_STDERR, fopen('/tmp/debug.txt', 'w+'));
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheaders);

        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------

    // parse the csrf token out of the cookies to set later when logging in
        list($headers, $body) = explode("\r\n\r\n", $data, 2);

        preg_match('/csrftoken=(.*?)[\b;\s]/i', $headers, $csrf_token);

        // next request the login page
        curl_setopt($ch, CURLOPT_URL, 'http://www.pinterest.com/login/');
        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------

    // perform login post    
        $login_header[] = 'X-CSRFToken: ' . $csrf_token[1];

        curl_setopt($ch, CURLOPT_URL, 'http://www.pinterest.com/resource/UserSessionResource/create/');
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $login_post);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array_merge($httpheaders, $login_header));
        curl_setopt($ch, CURLOPT_REFERER, 'http://www.pinterest.com/login/');
        curl_setopt($ch, CURLOPT_HEADER, 0);

        $data = curl_exec($ch);
    // ----------------------------------------------------------------------------


    if (curl_getinfo($ch, CURLINFO_HTTP_CODE) != 200)
    {
        echo "Error logging in.<br />";
        var_dump(curl_getinfo($ch));

    } else {
        $response = json_decode($data, true);

        if ($response === null)
        {
            echo "Failed to decode JSON response.<br /><br />";
            var_dump($response);
        } else if ($response['resource_response']['error'] === null) {
            echo "Logged in..";
        }
        print_r($response);
    }
}

I've tried to emulate the same headers that are sent to pinterest but I'm still not able to login for some reason..

回答1:

im not sure why your code doesn't work, but im pretty sure the array_merge will mess up the numeric keys (if any).. and that you're not handling X-CSRFToken header correctly (it changes on several places, and you only check it once).. anyway, doing this without an api isn't as easy as it may look like, but this works as of 22 february 2015, but be careful with the username/password, as i am probably not escaping it correctly (should probably escape it with json_encode() somehow)

EDIT: updated code so you get the logged in HTML on last request. (this proves beyond all reasonable doubt that you have in fact logged in ;) the way i checked it was to base64_encode() the output, then run this javascript in my browser: document.body.outerHTML=atob("base64"); , then i saw the same "you are logged in" screen)

<?php
error_reporting(E_ALL);
set_error_handler("exception_error_handler");
function exception_error_handler($errno, $errstr, $errfile, $errline ) {
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting
        return;
    }
    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}

you can see the code live in action here: http://codepad.viper-7.com/D8qk6q (for a few days until the server delete the code, anyway. or until some internet dickhead changes the password. it's a throwaway account anyway, obviously)

I'm pretty sure this is not going to work without getting an request_identifier which is required. To explain, when you load the page you get an unique number for that 'session' which is compared when you are going to log in. This is for a reason to avoid CSRF (Cross-Site Request Forgery). If you examine the actual POST, you will notice that not only an username or password are posted, but a few items more.

I think you should use https instead of http

$ch = curl_init('https://www.pinterest.com/'); // <-- HERE

and comment this line :

// $login_header[] = 'X-CSRFToken: ' . $csrf_token[1];
