如上代码并不完美,我们应该把cookie存到缓存中,不应该持久化,并且这样的持久化只能是单用户访问才行。
所以,其实我们只要设置
如下即可
- $data='username=demo_demo@126.com&password=123456qwe&remember=1';
- $curlobj = curl_init(); // 初始化
- curl_setopt($curlobj, CURLOPT_URL, "http://www.imooc.com/user/login"); // 设置访问网页的URL
- curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, true); // 执行之后不直接打印出来
-
- // Cookie相关设置,这部分设置需要在所有会话开始之前设置
- date_default_timezone_set('PRC'); // 使用Cookie时,必须先设置时区
- curl_setopt($curlobj, CURLOPT_COOKIESESSION, TRUE);
- curl_setopt($curlobj, CURLOPT_HEADER, 0);
- curl_setopt($curlobj, CURLOPT_COOKIE,session_name().'='.session_id());
- // 注释掉这行,因为这个设置必须关闭安全模式 以及关闭open_basedir,对服务器安全不利
- //curl_setopt($curlobj, CURLOPT_FOLLOWLOCATION, 1);
-
- curl_setopt($curlobj, CURLOPT_POST, 1);
- curl_setopt($curlobj, CURLOPT_POSTFIELDS, $data);
- curl_setopt($curlobj, CURLOPT_HTTPHEADER, array("application/x-www-form-urlencoded; charset=utf-8",
