itemredis文件：

local args = ngx.req.get_uri_args()
local id = args["id"]
local redis = require "resty.redis"
local cache = redis:new()


local ok,err =cache:connect("127.0.0.1",6379)

local item_model = cache:get("item_"..id)
if (item_model == ngx.null or item_model == nil)  then 
      local resq = ngx.location.capture("/item/get?id="..id)
	  item_model = resq.body
end

ngx.say(item_model)

conf文件

	location /luaitem/get{
		default_type "application/json";
	   content_by_lua_file  E:/openResty/openresty-1.19.3.1-win64/lua/itemredis.lua;
	 }

使用的是redis默认数据库0
