R2D的信息：
小米路由器2(R2D)
MiWiFi 开发版 2.25.203
打开『MT工具箱』提示：
No page is registered at '/web/misstar/index' .
If this url belongs to an extension, make sure it is properly installed.
If the extension was recently installed, try removing the /tmp/luci-indexcache file.
对应方法：
- ssh方root用户登录路由器后台；
- 执行命令：
vi /usr/lib/lua/luci/controller/web/index2.lua
- 加入如下内容：
module("luci.controller.web.index2", package.seeall)
function index()
local page = node("web","misstar")
page.target = firstchild()
page.title = ("")
page.order = 100
page.sysauth = "admin"
page.sysauth_authenticator = "jsonauth"
page.index = true

end
4.执行清理缓存命令：
rm -rf /tmp/luci-indexcache
