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

-
fdi:close()
-
fdo:close()
-
nixio.exec("/bin/sh", "-c", command)
-
end
-
end
效果如下:
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:
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
