大橙子网站建设,新征程启航
为企业提供网站建设、域名注册、服务器等服务
在个人页面,根据发布者个人和个人的信息来进行展示,如果是发布者,可以进行关注和取消关注。源码:https://github.com/limingios/wxProgram.git 中No.15和springboot
成都创新互联主打移动网站、网站设计制作、成都网站制作、网站改版、网络推广、网站维护、域名注册、等互联网信息服务,为各行业提供服务。在技术实力的保障下,我们为客户承诺稳定,放心的服务,根据网站的内容与功能再决定采用什么样的设计。最后,要实现符合网站需求的内容、功能与设计,我们还会规划稳定安全的技术方案做保障。
涉及2涨表,一个关联表,个人和粉丝的关联表,用户表。
