Convert php code to java for beter.com access - repost

I am working on a trading bot for [login to view URL] but I cannot get the code to work correctly. Their web page lists an example in php see [login to view URL] What I like is the function bter_query php to be rewritten in java. The result should be that the function can be called and obtain the balance for the currency on the web site. I will supply the key and secret the function requires. Thus the delivery for this project is a single java file that when run will obtain the balances from [login to view URL] You are free to use additional free libraries like those supplied from Apache as required. Below is the example from their web site. I have removed a few lines as they run examples not required. Hopefully it will still run in php and all you need to do is convert it to java. <?php function bter_query($path, array $req = array()) { // API settings, add your Key and Secret at here $key = ''; $secret = ''; // generate a nonce to avoid problems with 32bits systems $mt = explode(' ', microtime()); $req['nonce'] = $mt[1].substr($mt[0], 2, 6); // generate the POST data string $post_data = http_build_query($req, '', '&'); $sign = hash_hmac('sha512', $post_data, $secret); // generate the extra headers $headers = array( 'KEY: '.$key, 'SIGN: '.$sign, ); // curl handle (initialize if required) static $ch = null; if (is_null($ch)) { $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; Bter PHP bot; '.php_uname('a').'; PHP/'.phpversion().')' ); } curl_setopt($ch, CURLOPT_URL, '[login to view URL]'.$path); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // run the query $res = curl_exec($ch); if ($res === false) throw new Exception('Curl error: '.curl_error($ch)); //echo $res; $dec = json_decode($res, true); if (!$dec) throw new Exception('Invalid data: '.$res); return $dec; } function get_top_rate($pair, $type='BUY') { $rate = 0; // our curl handle (initialize if required) static $ch = null; if (is_null($ch)) { $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; Bter PHP bot; '.php_uname('a').'; PHP/'.phpversion().')' ); } curl_setopt($ch, CURLOPT_URL, '[login to view URL]'.$pair); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // run the query $res = curl_exec($ch); if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch)); //echo $res; $dec = json_decode($res, true); if (!$dec) throw new Exception('Invalid data: '.$res); if (strtoupper($type) == 'BUY') { $r = $dec['bids'][0]; $rate = $r[0]; } else { $r = end($dec['asks']); $rate = $r[0]; } return $rate; } try { // example 1: get funds var_dump(bter_query('1/private/getfunds')); } catch (Exception $e) { echo "Error:".$e->getMessage(); } ?>
