php获取cookie模拟登录实现方法

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

二、获取cookie 将cookie存入文件

2. $url = "http://1.2.3.4/";
3. $ch = curl_init();
4. curl_setopt($ch, curlopt_url, $url);
5. curl_setopt($ch, curlopt_header, 0);
6. curl_setopt($ch, curlopt_returntransfer, true);
7. curl_setopt($ch, curlopt_cookiejar, $cookie_jar);
8. $content = curl_exec($ch);
9. curl_close($ch);

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。

2. $ch = curl_init();
3. curl_setopt($ch, curlopt_url, 'http://1.2.3.4/getcheckpic.action?rand=6836.185874812305');
4. curl_setopt($ch, curlopt_cookiefile, $cookie_jar);
5. curl_setopt($ch, curlopt_header, 0);
6. curl_setopt($ch, curlopt_returntransfer, 1);
7. $ret = curl_exec($ch); // bbs.it-home.org
8. curl_close($ch);

四、post提交

2. $post = "name=2&usertype=1&passwd=asdf&logintype=1&rand=6836&imagefield.x=25&imagefield.y=7";
3. $ch = curl_init();
4. curl_setopt($ch, curlopt_url, "http://1.2.3.4/loginstudent.action");
5. curl_setopt($ch, curlopt_header, false);
6. curl_setopt($ch, curlopt_returntransfer,1);
7. curl_setopt($ch, curlopt_postfields, $post);
8. curl_setopt($ch, curlopt_cookiefile, $cookie_jar);
9. $result=curl_exec($ch);
10. curl_close($ch);

五、到指定页面获取数据

2. $ch = curl_init();
3. curl_setopt($ch, curlopt_url, "http://1.2.3.4/accountcarduser.action");
4. curl_setopt($ch, curlopt_header, false);
5. curl_setopt($ch, curlopt_header, 0);
6. curl_setopt($ch, curlopt_returntransfer,0);
7. curl_setopt($ch, curlopt_cookiefile, $cookie_jar);
8. $html=curl_exec($ch);
9. // var_dump($html);
10. curl_close($ch);
