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！
<?php namespace Home\Controller; use Think\Controller; class LoginController extends Controller { protected $cookieName = array('cookie_verify', 'cookie_verify'); protected $cookiePath = '/cookie/'; protected $cookiePathFile = array(); public function index() { $this->display(); } public function _initialize(){ foreach($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('/<div[^\<div]*?id\s*=https://www.jb51.net/article/\s*[\'\"]{1}div_msg[\'\"]{1}.*?>(.*?)<\/div>/s', $getBack, $match)){ echo 'matched\r\n'; print_r($match); }else{ echo $getBack, '<br />'; $paramsFull = parse_url($getBack); parse_str($paramsFull['query'], $paramsFull['parsedQuery']); if(!empty($paramsFull['parsedQuery']['Warn'])) { $msg = "您好，欢迎来P，请先登录。"; switch ($paramsFull['parsedQuery']['Warn']) { case '2': $msg = '您输入的验证码错误，请重试'; break; case '3': $msg = '该帐号不存在，还没帐号？'; break; case '5': $msg = '账户已注销'; break; case '6': $msg = '密码错误，如果连续错误3次半小时内不能登录！'; break; case '20': $msg = '今日密码错误3次及以上，请于半小时后再来登录！'; break; case '21': $msg = '今日您所在IP的所有帐号密码错误9次以上，请于半小时后再来登录！'; break; case '22': $msg = '登录失败，您所在IP今日登录的帐号过多！'; break; case '23': $msg = '登录失败，验证码失效！'; break; case '32': $msg = '该帐号已经绑定其他xx帐号！'; break; case '33': $msg = '一台电脑一天只能注册一个帐号！'; break; } $this->error($msg, '', 5); }else{ $_SESSION['user_id'] = '123456'; //登录设置session $this->success('登录P网站成功', U('Index/index'), 5); } } } /** * 获取验证码 */ public function getVerifyCode() { $img = $this->_cookieRequest('http://xxx.com/VerifyCode_Login.aspx?id=' . rand(10000,999999), null, true, 1); echo $img; } /** * 删除cookie */ public function clearCookie() { for($i = 0; $i <count($this->cookieName); $i++) { setcookie($this->cookieName[$i], '', time() - 3600); } // unlink($this->cookiePathFile); $this->success('清除cookie成功！'); } /** * 带COOKIE的访问curl * @param $url 访问地址 * @param bool|array $data 传递的数据 * @param bool $redirect 是否获取重定向的地址 * @return mixed 地址或者返回内容 */ public function _cookieRequest($url, $data = null, $redirect = false, $cookieNum = 0) { $ch = curl_init(); $params[CURLOPT_URL] = $url; //请求url地址 $params[CURLOPT_HEADER] = false; //是否返回响应头信息 $params[CURLOPT_RETURNTRANSFER] = true; //是否将结果返回 $params[CURLOPT_FOLLOWLOCATION] = true; //是否重定向 $params[CURLOPT_USERAGENT] = 'Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1'; if($data) { $params[CURLOPT_POST] = true; $params[CURLOPT_POSTFIELDS] = http_build_query($data); } //判断是否有cookie,有的话直接使用 if (!empty($_COOKIE[$this->cookieName[$cookieNum]]) && is_file($this->cookiePathFile[$cookieNum])) { $params[CURLOPT_COOKIEFILE] = $this->cookiePathFile[$cookieNum]; //这里判断cookie } else { // $cookie_jar = tempnam($cookie_path, 'cookie'); //产生一个cookie文件 $params[CURLOPT_COOKIEJAR] = $this->cookiePathFile[$cookieNum]; //写入cookie信息 setcookie($this->cookieName[$cookieNum], $this->cookiePathFile[$cookieNum], time() + 120); //保存cookie路径 } curl_setopt_array($ch, $params); //传入curl参数 $content = curl_exec($ch); $headers = curl_getinfo($ch); // echo $content; curl_close($ch); if ($url != $headers["url"] && $redirect == false) { return $headers["url"]; } return $content; } }
登录以后，就可以使用带cookie的访问其他页面了！
ps：php curl 登录淘宝
提交上去后显示为填写验证码，登录不上去
填写验证码提交：
