这个登录文件login.php里面调用了geetest 这一家的api验证码，输入验证码才能登录

不需要这个，直接输入用户名和密码就能登录，上面代码里面，应该删掉哪些代码呢？

上面调用的geetestlib.php里面代码是下面这个：

<?phpdefine('GT_API_SERVER', 'http://api.geetest.com');define('GT_SSL_SERVER', 'https://api.geetest.com');define('GT_SDK_VERSION', 'php_2.15.4.2.2');class GeetestLib{ function __construct() { $this->challenge = ""; } function set_captchaid($captcha_id) { $this->captcha_id = $captcha_id; } function set_privatekey($private_key) { $this->private_key = $private_key; } function register() { $this->challenge = $this->_send_request("/register.php", array("gt"=>$this->captcha_id)); if (strlen($this->challenge) != 32) { return 0; } return 1; } function get_widget($product, $popupbtnid="", $ssl=FALSE) { $params = array( "gt" => $this->captcha_id, "challenge" => $this->challenge, "product" => $product, ); if ($product == "popup") { $params["popupbtnid"] = $popupbtnid; } if(!isset($_SERVER['HTTPS'])){ $server = GT_API_SERVER; } else{ $server = GT_SSL_SERVER ; } return "<script type='text/javascript' src='".$server."/get.php?".http_build_query($params)."'></script>"; } function validate($challenge, $validate, $seccode) { if ( ! $this->_check_validate($challenge, $validate)) { return FALSE; } $query = http_build_query(array("seccode"=>$seccode,"sdk"=>GT_SDK_VERSION)); $codevalidate = $this->_http_post('api.geetest.com', '/validate.php', $query); if (strlen($codevalidate)>0 && $codevalidate==md5($seccode)) { return TRUE; } else if ($codevalidate == "false"){ return FALSE; } else { return $codevalidate; } } function _check_validate($challenge, $validate) { if (strlen($validate) != 32) { return FALSE; } if (md5($this->private_key.'geetest'.$challenge) != $validate) { return FALSE; } return TRUE; } function _send_request($path, $data, $method="GET") { if ($method=="GET") { $opts = array( 'http'=>array( 'method'=>"GET", 'timeout'=>2, ) ); $context = stream_context_create($opts); $response = file_get_contents(GT_API_SERVER.$path."?".http_build_query($data), false, $context); } return $response; } function _http_post($host,$path,$data,$port = 80){ $http_request = "POST $path HTTP/1.0\r\n"; $http_request .= "Host: $host\r\n"; $http_request .= "Content-Type: application/x-www-form-urlencoded\r\n"; $http_request .= "Content-Length: " . strlen($data) .

' . $errstr); } fwrite($fs, $http_request); while (!feof($fs)) $response .= fgets($fs, 1160); fclose($fs); $response = explode("\r\n\r\n", $response, 2); return $response[1]; }}?>
