PHP obtains Cookie to implement simulated login code

This article mainly shares with you PHP to obtain cookies to implement simulated login code. I hope it can help everyone.

1. Define Cookie storage path

Must use absolute path

$cookie_jar = dirname(__FILE__)."/pic.cookie";

2. Get Cookie

Save cookie to file

$url = "http://1.2.3.4/";$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);

3. Simulate the browser to obtain the verification code

The server verification code has a loophole. You can specify

to take out the cookie and submit it to the server together, so that the server thinks it is browsing Open the login 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);

4. 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);

5. Get data from the specified page

$ch = curl_init();
curl_setopt($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);
