    #        index  index.html index.htm;
    #    }
    #}
}

3、lua缓存编写

local cjlcache = ngx.shared.my_cache
local urlcache = ngx.var.request_uri;
local cjltest = cjlcache:get(urlcache)
if cjltest ~= "" and cjltest ~= nil then
  ngx.say(cjltest)
else
--  os.execute("curl -o /usr/servers/nginx/conf/templates/test1.html https://holdall.cn");
  local f = io.popen("curl http://119.45.255.46:8080" .. urlcache)
  local context = f:read("*a")
  cjlcache:set(urlcache,context,600)
  ngx.say(context)
end
- ```

粗暴的方法，缓存下每张页面的内容，下次访问直接通过nginx就返回即可，无需再进行交互，从而达到快速响应目的
