[android] 与PHP的session进行交互demo

概述从MainActivity跳转到MailIndexActivity,第一个请求接口设置session,第二个activity请求接口获取session java代码中获取header头里面的Set-C

从MainActivity跳转到MailindexActivity,第一个请求接口设置session,第二个activity请求接口获取session

java代码中获取header头里面的Set-cookie

请求的时候,设置头信息cookie,就可以相当于浏览器获取session

PHP文件:

<?PHPsession_start();if(empty($_SESSION)){   echo "设置session";   $_SESSION['name']=1;    echo session_ID();}else{   echo "获取session";   print_r(); }
