UCenter开发手册API接口.doc(2)

输入的参数 $get['uid'] 为用户 ID，$get['credit'] 为积分编号。接口运行完毕输出积分值。getcredit 接口示例 (PHP)4、函数定义接口函数中必须包含以下函数，否则无法正确对 UCenter 传递过来的数据进行解码。 function authcode($string, $operation = 'DECODE', $key = '', $expiry = 0) {$ckey_length = 4;$key = md5($key ? $key : UC_KEY);$keya = md5(substr($key, 0, 16));$keyb = md5(substr($key, 16, 16));$keyc = $ckey_length ? ($operation == 'DECODE' ? substr($string, 0, $ckey_length): substr(md5(microtime()), -$ckey_length)) : '';$cryptkey = $keya.md5($keya.$keyc);$key_length = strlen($cryptkey);$string = $operation == 'DECODE' ? base64_decode(substr($string, $ckey_length)) : sprintf('0d', $expiry ? $expiry + time() : 0).substr(md5($string.$keyb), 0, 16).$string;$string_length = strlen($string);$result = '';$box = range(0, 255);$rndkey = array();for($i = 0; $i <= 255; $i++) {$rndkey[$i] = ord($cryptkey[$i % $key_length]);}for($j = $i = 0; $i < 256; $i++) {$j = ($j + $box[$i] + $rndkey[$i]) % 256;$tmp = $box[$i];$box[$i] = $box[$j];$box[$j] = $tmp;}for($a = $j = $i = 0; $i < $string_length; $i++) {$a = ($a + 1) % 256;$j = ($j + $box[$a]) % 256;$tmp = $box[$a];$box[$a] = $box[$j];$box[$j] = $tmp;$result .= chr(ord($string[$i]) ^ ($box[($box[$a] + $box[$j]) % 256]));}if($operation == 'DECODE') {if((substr($result, 0, 10) == 0 || substr($result, 0, 10) - time() > 0) && substr($result, 10, 16) == substr(md5(substr($result, 26).$keyb), 0, 16)) {return substr($result, 26);} else {return '';}} else {return $keyc.str_replace('=', '', base64_encode($result));}}function uc_serialize($arr, $htmlon = 0) {include_once UC_CLIENT_ROOT.'./lib/xml.class.php';return xml_serialize($arr, $htmlon);}function uc_unserialize($s) {include_once UC_CLIENT_ROOT.'./lib/xml.class.php';return xml_unserialize($s);}
