1. Define Cookie storage path

Must use absolute path

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

Copy after login

2. Obtain Cookie

Save cookies to file

<span $url</span> = "http://1.2.3.4/"<span ;
</span><span $ch</span> =<span  curl_init();
curl_setopt(</span><span $ch</span>, CURLOPT_URL, <span $url</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_HEADER, 0<span );
curl_setopt(</span><span $ch</span>, CURLOPT_RETURNTRANSFER, <span true</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_COOKIEJAR, <span $cookie_jar</span><span );
</span><span $content</span> = curl_exec(<span $ch</span><span );
curl_close(</span><span $ch</span>);

Copy after login

3. Simulate the browser to obtain the verification code

The server verification code has loopholes, you can specify it yourself

Take out the cookie and submit it to the server together, making the server think it is a browser opening the login page

<span $ch</span> =<span  curl_init();
curl_setopt(</span><span $ch</span>, CURLOPT_URL, 'http://1.2.3.4/getCheckpic.action?rand=6836.185874812305'<span );
curl_setopt(</span><span $ch</span>, CURLOPT_COOKIEFILE, <span $cookie_jar</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_HEADER, 0<span );
curl_setopt(</span><span $ch</span>, CURLOPT_RETURNTRANSFER, 1<span );
</span><span $ret</span> = curl_exec(<span $ch</span><span );
curl_close(</span><span $ch</span>);

Copy after login

4. POST submission

<span $post</span> = "name=2&userType=1&passwd=asdf&loginType=1&rand=6836&imageField.x=25&imageField.y=7"<span ;    
</span><span $ch</span> =<span  curl_init();
curl_setopt(</span><span $ch</span>, CURLOPT_URL, "http://1.2.3.4/loginstudent.action"<span );
curl_setopt(</span><span $ch</span>, CURLOPT_HEADER, <span false</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_RETURNTRANSFER,1<span );
curl_setopt(</span><span $ch</span>, CURLOPT_POSTFIELDS, <span $post</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_COOKIEFILE, <span $cookie_jar</span><span );
</span><span $result</span>=curl_exec(<span $ch</span><span );
curl_close(</span><span $ch</span>);

Copy after login

5. Go to the designated page to obtain data

<span $ch</span> =<span  curl_init();
curl_setopt(</span><span $ch</span>, CURLOPT_URL, "http://1.2.3.4/accountcardUser.action"<span );
curl_setopt(</span><span $ch</span>, CURLOPT_HEADER, <span false</span><span );
curl_setopt(</span><span $ch</span>, CURLOPT_HEADER, 0<span );
curl_setopt(</span><span $ch</span>, CURLOPT_RETURNTRANSFER,0<span );        
curl_setopt(</span><span $ch</span>, CURLOPT_COOKIEFILE, <span $cookie_jar</span><span );
</span><span $html</span>=curl_exec(<span $ch</span><span );
</span><span //</span><span  var_dump($html);</span>
curl_close(<span $ch</span>);
