项目经验之:项目中多个子系统之间共享登陆解决方案求解_也可叫免登陆

当,,,项目中现在有这样一种情况,,,,想要做到只需登陆一次即可,访问所有的外围子系统...........

也就是说子系统各有一套权限与登陆界面,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

现在我想要在不改动子系统的情况下,,,,,,,,,,,,,做到只需登陆一次即可访问所有的系统...................

我在网上看到一种方法,测试了下,能得到子系统的HTML源代码,,,,,,,但路径出现问题..............

不知大家有什么好的解决方案...............在些学习下

注意单点登陆是不能解决这说的这种情况的.................不清楚大家想过没有,

子系统的登陆存储是各不相同的..............
