openwrt中luci界面中简单的添加一个配置说明

布满荆棘的人生 2022-06-04 01:20 1019阅读 0赞

1.先在system中添加一个ipv6config

操作：先在/usr/lib/ lua/luci/controller/admin/system.lua 文件中的index页面中添加

entry({"admin", "system", "ipv6config"}, cbi("admin_system/ipv6config"), "ipv6config", 30).dependent=false

system.lua页面全部代码

效果如下:![1344995614_8063.jpg][]

2. 编写model

操作：在先在/usr/lib/ lua/luci/model/cbi/admin\_system文件中的添加ipv6config.lua 文件

文件全部代码

require("luci.sys")
    require("luci.sys.zoneinfo")
    require("luci.tools.webadmin")
    require("luci.fs")
    require("luci.config")
    
    local m, s, o
    
    m = Map("ipv6config", translate("ipv6config"), translate("this is ipv6 pre config"))
    m:chain("luci")
    
    s = m:section(TypedSection, "ipv6config", translate("System ipv6"))
    s.anonymous = true
    s.addremove = false
    
    s:tab("general",  translate("General Settings"))
    
    o = s:taboption("general", Value, "ipv6pre", translate("ipv6 pre config"))
    o.datatype = "ipv6config"
    
    function o.write(self, section, value)
    	Value.write(self, section, value)
    end
    
    return m

效果：![1344995770_7077.jpg][]

3. 添加配置文件

操作：在/etc/config中添加ipv6config文件

代码：

config 'ipv6config'
    	option 'ipv6pre' '2011:86'

ps: 注意

config 中的ipv6config文件中的ipv6confg与ipv6pre与model中ipv6config.lua两个字段的对应
