php CURL带有验证码验证登录的例子
以前我们写过很多利用curl模拟登录的,今天我来介绍两个例子都可以实现对方网站有验证码图片时由用户输入验证码之后再验证.
例子,读取远程的验证码利用框架加载到此页面然后手工输入,代码如下:
<?php /** * @author 追逐__something * @version $id */ define('SCRIPT_ROOT', dirname(__FILE__) . '/'); $act = trim($_REQUEST['act']); switch ($act) { case 'login': // 获取验证码 $code = trim($_REQUEST['code']); // $loginParams为curl模拟登录时post的参数 $loginParams['act'] = 'login'; $loginParams['password'] = '111111'; $loginParams['username'] = 'wlpadmin'; $loginParams['vcode'] = $code; // $cookieFile 为加载验证码时保存的cookie文件名 $cookieFile = SCRIPT_ROOT . 'cookie.tmp'; // $targetUrl curl 提交的目标地址 www.phprm.com $targetUrl = 'http://local.xx.com/admin/login.php'; // 参数重置 $content = curlLogin($targetUrl, $cookieFile, $loginParams); echo $content; break; case 'authcode': // Content-Type 验证码的图片类型 header('Content-Type:image/png'); showAuthcode('http://local.xx.com/admin/vcode.php?r=0.03192671708666017'); exit; break; } /** * 模拟登录 * @param string $url 提交到的地址 * @param string $cookieFile 保存cookie的文件 * @param string $loginParams 提交时要post的参数 * @return string $content 返回的内容 */ function curlLogin($url, $cookieFile, $loginParams) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile); //同时发送Cookie curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $loginParams); //提交查询信息 $content = curl_exec($ch); curl_close($ch); return $content; } /** * 加载目标网站图片验证码 * @param string $authcode_url 目标网站验证码地址 */ function showAuthcode($authcode_url) { $cookieFile = SCRIPT_ROOT . 'cookie.tmp'; $ch = curl_init($authcode_url); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); // 把返回来的cookie信息保存在文件中 curl_exec($ch); curl_close($ch); } ?> <iframe src="?act=authcode" style='width: 100px; height:40px ' frameborder=0 ></iframe> <form> <input type="hidden" name="act" value="login"> <input type="text" name="code" /> <input type="submit" name="submit" > </form>
例子:思路就是获取到验证码之后把验证码存储为一个图片,然后程序休眠20秒,在20秒之后由用户手动查看图片,并把验证码填写到code.txt文件中,20秒休眠完成后,程序会读code.txt的验证码,这样再带着验证码进行登录操作,代码如下:
<?php //初始化变量 $cookie_file = "tmp.cookie"; $login_url = "http://xxx.com/logon.php"; $verify_code_url = "http://xxx.com/verifyCode.php"; echo "正在获取COOKIE...n"; $curlj = curl_init(); $timeout = 5; curl_setopt($curl, CURLOPT_URL, $login_url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie_file); //获取COOKIE并存储 $contents = curl_exec($curl); curl_close($curl); echo "COOKIE获取完成,正在取验证码...n"; //取出验证码 www.phprm.com $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $verify_code_url); curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file); curl_setopt($curl, CURLOPT_HEADER, 0); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $img = curl_exec($curl); curl_close($curl); $fp = fopen("verifyCode.jpg", "w"); fwrite($fp, $img); fclose($fp); echo "验证码取出完成,正在休眠,20秒内请把验证码填入code.txt并保存n"; //停止运行20秒 sleep(20); echo "休眠完成,开始取验证码...n"; $code = file_get_contents("code.txt"); echo "验证码成功取出:$coden"; echo "正在准备模拟登录...n"; $post = "username=maben&pwd=hahahaha&verifycode=$code"; $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_HEADER, false); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $post); curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file); $result = curl_exec($curl); curl_close($curl); //这一块根据自己抓包获取到的网站上的数据来做判断 if (substr_count($result, "登录成功")) { echo "登录成功n"; } else { echo "登录失败n"; exit; }
