本篇是记录在 Openwrt 镜像中添加 自定义的 web 配置界面过程，编译进 openwrt 的系统镜像中。
第一步 建立项目文件目录
mkdir -p feeds/luci/applications/luci-app-Gateway
mkdir -p feeds/luci/applications/luci-app-Gateway/config
mkdir -p feeds/luci/applications/luci-app-Gateway/luci
mkdir -p feeds/luci/applications/luci-app-Gateway/module
第二步 编写 controller 的 lua 源码
wooya@hi-wooya:~/openwrt-hiwooya/feeds/luci/applications/luci-app-Gateway$ cat luasrc/controller/gateway.lua
module("luci.controller.gateway", package.seeall)
function index()
entry({"admin", "services", "Gateway"}, cbi("gateway/gateway_conf"), translate("Gateway"), nil)
entry({"admin", "services", "Service"}, template("gateway/helloworld"), _("Online help"), nil)
end
第三步 编写 model 模块内容
wooya@hi-wooya:~/openwrt-hiwooya/feeds/luci/applications/luci-app-Gateway$ cat luasrc/model/cbi/gateway/gateway_conf.lua
m = Map("gatewayConf", translate("Gateway")) -- cbi_file is the config file in /etc/config
g = m:section(TypedSection, "gateway") -- info is the section called info in cbi_file
sn = g:option(Value, "sn", translate("Gateway SN"),"BCD code Eg:abcdef202202110001000101");
addr = g:option(Value,"IPv4addr",translate("Server IPv4:Port"),"eg:172.168.10.211:1813");
heart= g:option(Value, "HeartBeat", translate("MQTT HeartBeat"), "d:second");
name = g:option(Value, "UserName", translate("MQTT UserName"));
pwd = g:option(Value, "Password", translate("MQTT Password"));
return m
第四步 编码在线帮助web 网页
wooya@hi-wooya:~/openwrt-hiwooya/feeds/luci/applications/luci-app-Gateway$ cat luasrc/view/gateway/helloworld.htm
<%+header%>
<h1><%: HelloWorld %></h1>
<%+footer%>
第五步 创建配置参数确实值
wooya@hi-wooya:~/openwrt-hiwooya/feeds/luci/applications/luci-app-Gateway/root/etc/config$ cat gatewayConf
config gateway 'parament'
option HeartBeat '60'
option sn 'abcdef202202110001000101'
option UserName 'admin'
option Password '123456'
option IPv4addr '81.70.211.95:1883'
此文件镜像打包后的系统路径: etc/config 网页中显示和配置内容。
第六步 验证文件路径
wooya@hi-wooya:~/openwrt-hiwooya/feeds/luci/applications/luci-app-Gateway$ tree -L 5
.
├── luasrc
│ ├── controller
│ │ └── gateway.lua
│ ├── model
│ │ └── cbi
│ │ └── gateway
│ │ └── gateway_conf.lua
│ └── view
│ └── gateway
│ └── helloworld.htm
├── Makefile
└── root
└── etc
└── config
└── gatewayConf
至此我们把 luci 相关源码准备好，开始编译验证
第七步 编译 luci app 模块
建立软连接并安装 luci_app_gateway 模板
//> ln -s
wooya@hi-wooya:~/openwrt-hiwooya$ cd package/feeds/luci
wooya@hi-wooya:~/openwrt-hiwooya$ package/feeds/luci$ ln -s ../../../feeds/luci/applications/luci-app-Gateway/ .
wooya@hi-wooya:~/openwrt-hiwooya$ package/feeds/luci$ ls luci-app-Gateway
luasrc Makefile root
wooya@hi-wooya:~/openwrt-hiwooya$ package/feeds/luci$ ls luci-app-Gateway/luasrc/
controller model view
//> install -p luci
wooya@hi-wooya:~/openwrt-hiwooya$ ./scripts/feeds install -a -p luci
Installing all packages from feed luci.
Installing package 'luci-app-Gateway'
# make menuconfig
Symbol: DEFAULT_luci-app-Gateway [=DEFAULT_luci-app-Gateway]
│ Type : unknown
│
│
│ Symbol: PACKAGE_luci-app-Gateway [=y]
│ Type : tristate
│ Prompt: luci-app-Gateway........................... LuCI Support for Gateway-menu
│ Location:
│ -> LuCI
│ (1) -> 3. Applications
│ Defined at tmp/.config-package.in:27354
│ Selects: PACKAGE_librt [=y] && PACKAGE_libc [=y] && PACKAGE_libpthread [=y] && PACKAGE_libssp [=n]
烧写镜像后，可以在 services 菜单中，看到 Gateway 和 online help 子菜单内容。下一篇将分享如果在 C++ 程序通过 libuci.so 库
方式，获取web设置内容。
如果您对 Luci 相关语法有些陌生，可以移步至 openwrt.org 网站中wiki部分检索。
