rbac没权限返回如何判断跳转到页面还是ajax返回

Jun 06, 2016 pm 08:33 PM
php rbac thinkphp

做后台过程中遇到个问题
用的是thinkphp自己的rbac
每个baseController里检查权限
当没有权限的时候,输出没有权限的页面
但是如果是按钮的话,点击后没有权限是前端页面是没有任何反馈的。只有F12开发者工具才能看到

所以,怎样在判断到没有权限后,有正确的返回方式,如果是页面让他进入没有权限的页面,如果是按钮让他返回ajax弹出您无权限的框

根据 HTTP 请求的 header 判断是 Ajax 请求还是正常的页面请求,如果是普通的请求就直接跳转到登陆页,如果是Ajax请求(带X-Requested-With: XMLHttpRequest) 就返回HTTP status 401,或者类似能表达未登录状态的通用数据,我的处理是{ status : 1, message:'', data: [...]} 这样的数据结构,前端根据返回数据的status判断当前是否成功取到数据,然后对封装的数据进行进一步处理

RestController有response()方法可以返回json, 或者自己写一个返回json的方法。
比如返回:

<code>{error:1, msg: "无权限访问xxx"}
</code>
Copy after login

前端判断 data.error 就可以了。
