网上的很多模拟登录程序,大都是通过服务程序apache之类的运行,获取到验证码之后显示在网页上,然后填上再POST出去

  本文提供了一个程序实例,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。具体代码如下:

  /**

  * 模拟登录

  */

  //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

  $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:$code\n";

  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;

  }

  //OK,开始做你想做的事吧。。。。。
