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。。。。。
