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