403当我发送POST请求时被禁止

Question

Good evening, I wanted to connect to the https://accounts.nintendo.com/ site via twitter with cURL, so I first made a GET request on the nintendo site connection page to get the csrf_token and then a POST request to the action url of the nintendo site form in order to connect via twitter.

Normally when everything is going well the answer request should send me back: 302 Found then the oAuth link to connect me via twitter.

I tried of modify the userAgent and Header

<?php
include('simple_html_dom.php');

// SHOW THE PAGE TO GET CSRF TOKEN
$ch = curl_init();

$url = 'https://accounts.nintendo.com/login';



curl_setopt_array($ch,
  array(
     CURLOPT_URL => $url,

     CURLOPT_CAINFO => dirname(__FILE__)."/cacert.pem",
     CURLOPT_COOKIESESSION => false,
     CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36",
     CURLOPT_HTTPHEADER => array(
       'Host: accounts.nintendo.com',
       'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Language: fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3',
       'Pragma: ',

       'Connection: keep-alive',

     ),
     CURLINFO_HEADER_OUT => true,
     CURLOPT_COOKIEFILE => dirname(__FILE__) . "/cookies.txt",
     CURLOPT_COOKIEJAR => dirname(__FILE__) . "/cookies.txt",
     CURLOPT_FRESH_CONNECT => false,


    // The data to transfer with the response.

    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_RETURNTRANSFER => true,


  )
);


$data = curl_exec($ch);


// PARSER THE TOKEN CSRF
$dom = new simple_html_dom();

$html = $dom->load($data);


foreach($html->find('li[class="LoginForm_snsButton LoginForm_snsButton-row LoginForm_snsButton-twitter"] input[name="csrf_token"]') as $element)
{
  $csrf_token = $element->value.'<br/>';

}

curl_close($ch);

//SEND POST REQUEST

$ch2 = curl_init();

$url = 'https://accounts.nintendo.com/federation/twitter';


$postData = array(

  "post_federation_redirect_uri" => "https://accounts.nintendo.com/",
  "post_federation_reauthenticate" => "",
  "redirect_after" => "5",
  "csrf_token" => $csrf_token,
  "display" => ""
);
curl_setopt_array($ch2,
  array(
     CURLOPT_URL => $url,

     CURLOPT_CAINFO => dirname(__FILE__)."/cacert.pem",
     CURLOPT_COOKIESESSION => false,
     CURLOPT_USERAGENT => "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0",


     CURLOPT_COOKIEFILE => dirname(__FILE__) . "/cookies.txt",
     CURLOPT_COOKIEJAR => dirname(__FILE__) . "/cookies.txt",
     CURLOPT_FRESH_CONNECT => false,
     CURLOPT_CUSTOMREQUEST => 'POST',
     CURLOPT_POSTFIELDS => http_build_query($postData),
     CURLINFO_HEADER_OUT => true,
    // The data to transfer with the response.
    CURLOPT_HEADER => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_RETURNTRANSFER => true,


  )
);

$exec = curl_exec($ch2);
$header = curl_getinfo($ch2);
echo $header['request_header'].'</br></br></br>';

echo $header['header_size'];

echo $exec;
curl_close($ch2);


?>

the problem is that I get a nice 403 Forbidden (I don't know if it's because I'm making the request from localhost), here's a screen showing the request header, the response header and the content of the site's response: http://www.noelshack.com/2019-15-6-1555110358-screenshot-1.jpg

Answer 1

What is your chmod permission for simple_html_dom.php and for your script ?

If you did not put permission 644 try this :

Chmod both files with $chmod 644 YourScript.php

And, in a second case reload your script on your Web-Browser and wait for error 403 and look on your Log File.

• In case you use Apache2 look at /var/log/apache2/error.log
• Otherwise or if you use Nginx go in /var/log/nginx/error.log

Give me your results so I could help you a little better. ;)
