代码：

ngx.header.content_type="application/json;charset=utf8" local uri_args = ngx.req.get_uri_args(); local id = uri_args["id"]; --获取本地缓存 local cache_ngx = ngx.shared.dis_cache; --根据ID 获取本地缓存数据 local contentCache = cache_ngx:get('content_cache_'..id); if contentCache == "" or contentCache == nil then local redis = require("resty.redis"); local red = redis:new() red:set_timeout(2000) red:connect("192.168.211.132", 6379) local rescontent=red:get("content_"..id); if ngx.null == rescontent then local cjson = require("cjson"); local mysql = require("resty.mysql"); local db = mysql:new(); db:set_timeout(2000) local props = { host = "192.168.211.132", port = 3306, database = "changgou_content", user = "root", password = "123456" } local res = db:connect(props); local select_sql = "select url,pic from tb_content where status ='1' and category_id="..id.." order by sort_order"; res = db:query(select_sql); local responsejson = cjson.encode(res); red:set("content_"..id,responsejson); ngx.say(responsejson); db:close() else cache_ngx:set('content_cache_'..id, rescontent, 10*60); ngx.say(rescontent) end red:close() else ngx.say(contentCache) end

配置的nginx.conf的配置文件

使用对照修改参数！！！
