luci 之 MVC 模組

參考 寫個 LuCI 模組

function index()
  -- 定義節點, request 時會呼叫 action_time
  page = entry({"myapp", "mymodule", "time.htm"}, call("action_time"))

  -- 沒有上層節點
  page.dependent = false
  -- 假如是葉節點, 就設成 true 避免錯誤
  page.leaf = true
end

function action_time()
  luci.http.prepare_content("text/html")
  luci.http.write("<h1>Hello LuCi</h1>")
  luci.http.write("<h2>Current time: " .. os.date("%D %T") .. "</h2>")
end
