需求是这样的,需要登录带验证码的网站,获取数据,但是不可能人为一直去记录数据,想通过自动采集的方式进行,如下是试验出来的结果代码!有需要的可以参考下!
display(); } public function _initialize(){ foreach($this->cookieName as $key => $name) { $this->cookiePathFile[] = ROOT_PATH . $this->cookiePath . $this->cookieName[$key] . '_xxx.txt'; } } /** * 登录xxx */ public function xxxLogin() { $username = I('username'); $password = I('password'); $verifyCode = I('verify'); $loginData = array( '__VIEWSTATE' => '/wEPDwUKMTU0MzAzOTU4NmQYAQUeX19Db250cm9sc1JlcXVpcmVQb3N0QmFja0tleV9fFgEFDExvZ2luX1N1Ym1pdL/yae69NsY163G3yuP0lxjz8oXu', //不把参数补全可能会不被响应哦 '__VIEWSTATEGENERATOR' => 'DC42DE27', 'txt_UserName' => $username, 'txt_PWD' => $password, 'txt_VerifyCode' => $verifyCode, 'SMONEY' => 'ABC', 'Login_Submit.x' => '52', 'Login_Submit.y' => '19', ); $getBack = $this->_cookieRequest('http://xxx.com/noLogin.aspx', $loginData); if(preg_match('/(.*?)/s', $getBack, $match)){ echo 'matched\r\n'; print_r($match); }else{ echo $getBack, '
