PHP Get cookie Emulation Login

I. Defining a cookie Storage path

Absolute path must be used

$cookie _jar = dirname (__file__). " /pic.cookie ";

$cookie _file = dirname (__file__). ' /cookie.txt ';

$cookie _file = Tempnam ("tmp", "Cookie");

Second, access to cookies

$url = "http://1.2.3.4/";

$ch = Curl_init ();

curl_setopt ($ch, Curlopt_url, $url);

curl_setopt ($ch, Curlopt_header, 0);

curl_setopt ($ch, Curlopt_returntransfer, true);

curl_setopt ($ch, Curlopt_cookiejar, $cookie _jar);

$content = curl_exec ($ch);

Curl_close ($ch);

Third, the simulation browser to obtain the verification code

The server verification code is a vulnerability, you can specify

Take out the cookie and submit it to the server to let the server think it is the browser to open the landing page

$ch = Curl_init ();

curl_setopt ($ch, Curlopt_url, ' http://1.2.3.4/getCheckpic.action?rand=6836.185874812305 ');

curl_setopt ($ch, Curlopt_cookiefile, $cookie _jar);

curl_setopt ($ch, Curlopt_header, 0);

curl_setopt ($ch, Curlopt_returntransfer, 1);

$ret = curl_exec ($ch);

Curl_close ($ch);

Iv. Post Submission

$post = "name=2&usertype=1&passwd=asdf&logintype=1&rand=6836&imagefield.x=25& Imagefield.y=7 ";

$ch = Curl_init ();

curl_setopt ($ch, Curlopt_url, "http://1.2.3.4/loginstudent.action");

curl_setopt ($ch, Curlopt_header, false);

curl_setopt ($ch, curlopt_returntransfer,1);

curl_setopt ($ch, Curlopt_postfields, $post);

curl_setopt ($ch, Curlopt_cookiefile, $cookie _jar);

$result =curl_exec ($ch);

Curl_close ($ch);

Five, to the specified page to obtain data

$ch = Curl_init ();

curl_setopt ($ch, Curlopt_url, "http://1.2.3.4/accountcardUser.action");

curl_setopt ($ch, Curlopt_header, false);

curl_setopt ($ch, Curlopt_header, 0);

curl_setopt ($ch, curlopt_returntransfer,0);

curl_setopt ($ch, Curlopt_cookiefile, $cookie _jar);

$html =curl_exec ($ch);

Var_dump ($html);

Curl_close ($ch);
