PHP curl模拟登录带验证码的网站

2015-12-02 16:42作者：fang

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 HomeController;

use ThinkController;

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]*?ids*=s*['"]{1}div_msg['"]{1}.*?>(.*?)</div>/s', $getBack, $match)){

echo 'matchedrn';

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
