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
-
-
-
-
- define('SCRIPT_ROOT',dirname(__FILE__).'/');
- $act = trim($_REQUEST['act']);
- switch($act)
- {
- case 'login':
-
- $code = trim($_REQUEST['code']);
-
-
- $loginParams['act'] = 'login';
- $loginParams['password'] = '111111';
- $loginParams['username'] = 'wlpadmin';
- $loginParams['vcode'] = $code;
-
-
- $cookieFile = SCRIPT_ROOT.'cookie.tmp';
-
-
- $targetUrl = 'http://local.xx.com/admin/login.php';
-
-
- $content = curlLogin($targetUrl, $cookieFile, $loginParams);
- echo $content;
- break;
- case 'authcode':
-
- header('Content-Type:image/png');
- showAuthcode('http://local.xx.com/admin/vcode.php?r=0.03192671708666017');
- exit;
- break;
- }
-
-
-
-
-
-
-
-
- function curlLogin($url, $cookieFile, $loginParams)
- {
- $ch = curl_init($url);
- curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile);
- curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
- curl_setopt($ch,CURLOPT_POST, 1);
- curl_setopt($ch,CURLOPT_POSTFIELDS, $loginParams);
- $content = curl_exec($ch);
- curl_close($ch);
- return $content;
- }
-
-
-
-
-
- function showAuthcode( $authcode_url )
- {
- $cookieFile = SCRIPT_ROOT.'cookie.tmp';
- $ch = curl_init($authcode_url);
- curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFile);
- curl_exec($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:
-
- $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);
- $contents = curl_exec($curl);
- curl_close($curl);
-
- echo "COOKIE获取完成,正在取验证码...n";
-
- $curl = curl_init();
- curl_setopt($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";
-
- 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($curl);
-
-
- if(substr_count($result,"登录成功")){
- echo "登录成功n";
- }else{
- echo "登录失败n";
- exit;
- }
