i have a problem with the mobile confirmation, this is my code: public static function bufferizeSecret($secret) { if (preg_match('/[0-9a-fA-F]{40}/', $secret)) { return pack('H*', $secret); } if (preg_match('/^(?:[A-Za-z0-9+\/]{4})*(?:[A-Za-z0-9+\/]{2}==|[A-Za-z0-9+\/]{3}=|[A-Za-z0-9+\/]{4})$/', $secret)) { return base64_decode($secret); } return $secret; } public function generateConfirmationUrl($tag = 'conf') { return 'https://steamcommunity.com/mobileconf/conf?'. $this->generateConfirmationQueryParams($tag); } public function generateConfirmationQueryParams($tag) { $time = time(); return 'p=android:' . $this->deviceId . '&a=' . $_SESSION['steamid'] . '&k=' . $this->getConfirmationKey($time, $tag) . '&t=' . $time . '&m=android&tag=' . $tag; } public static function getConfirmationKey($time, $tag) { if (empty($tag)) { $buf = pack('NN', 0, $time); } else { $buf = pack('NNa*', 0, $time, $tag); } $hmac = hash_hmac('sha1', $buf, self::bufferizeSecret($secret), true); return base64_encode($hmac); } public function fetchConfirmations() { $url = $this->generateConfirmationUrl();echo $url; $confirmations = []; $response = ''; try { $response = $this->request('POST', $url, null);print_r($response); } catch (\Exception $ex) { return $confirmations; } if (strpos($response, '<div>Nothing to confirm</div>') === false) { $confIdRegex = '/data-confid="(\d+)"/'; $confKeyRegex = '/data-key="(\d+)"/'; $confDescRegex = '/<div>((Confirm|Trade with|Sell -) .+)<\/div>/'; preg_match_all($confIdRegex, $response, $confIdMatches); preg_match_all($confKeyRegex, $response, $confKeyMatches); preg_match_all($confDescRegex, $response, $confDescMatches); if (count($confIdMatches[1]) > 0 && count($confKeyMatches[1]) > 0 && count($confDescMatches) > 0) { for ($i = 0; $i < count($confIdMatches[1]); $i++) { $confId = $confIdMatches[1][$i]; $confKey = $confKeyMatches[1][$i]; $confDesc = $confDescMatches[1][$i]; //$confirmations[] = new Confirmation($confId, $confKey, $confDesc); } } } return $confirmations; } public function request($type, $url, $data=null){if(isset($_SESSION['oauth_token'])){$this->mobile=true;}$c = curl_init();curl_setopt($c, CURLOPT_HEADER, false);curl_setopt($c, CURLOPT_NOBODY, false);curl_setopt($c, CURLOPT_URL, $url);curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);if ($this->mobile) { // curl_setopt($c, CURLOPT_HTTPHEADER, ["X-Requested-With: com.valvesoftware.android.steam.community"]); curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Linux; U; Android 4.1.1; en-us; Google Nexus 4 - 4.1.1 - API 16 - 768x1280 Build/JRO03S) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30"); curl_setopt($c, CURLOPT_COOKIE, $this->buildCookie(self::$DEFAULT_MOBILE_COOKIES)); } else {curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.133 Safari/537.36"); }if(isset($data)){curl_setopt($c, CURLOPT_POST, 1);curl_setopt($c, CURLOPT_POSTFIELDS, http_build_query($data));}curl_setopt($c, CURLOPT_RETURNTRANSFER, true);curl_setopt($c, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);curl_setopt($c, CURLOPT_CUSTOMREQUEST, strtoupper($type));$return = curl_exec($c);if(curl_error($c)){echo 'error:' . curl_error($c);}curl_close($c); //print_r($return);return $return;} private function buildCookie($cookie) { $out = ""; foreach ($cookie as $k => $c) { $out .= "{$k}={$c}; "; } return $out; } but i don't know why it give this error Bad RequestYour browser sent a request that this server could not understand. could anyone help me?
