一、定义Cookie存储路径

必须使用绝对路径

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

 

二、获取Cookie

将cookie存入文件

<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>);

 

三、模拟浏览器获取验证码

该服务器验证码有漏洞，可以自己指定

取出cookie，一起提交给服务器，让服务器以为是浏览器打开登陆页面

<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>);

 

四、POST提交

<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>);

 

五、到指定页面获取数据

<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>);
