项目结构 如何快速上手
http篇
1、controller包就相当于RestController这里返回了一个Person对象当你需要新建一个接口时再新写一个func仿照下面的方法就行了
package controllerimport (net/httptestproject12/commontestproject12/entitytestproject12/util
)// PersonHandler 无入参返回person类
func PersonHandler(w http.ResponseWriter, r *http.Request) {// 创建一个Person对象person : entity.Person{Name: John Doe,Age: 30,Title: Software Engineer,}messageHex : FFFFFFutil.SendHexMessageToAllUser(messageHex)// 封装为JSON格式的CommonResult并写入响应体common.WriteJSONResponse(w, http.StatusOK, common.DefaultSuccessMsg, person)
}
2、router.go负责配置路由下面的代码中server.AddRoute的key相当于RequestMapping(“/person”)value是上面文件在controller包下方法是PersonHandler
package routerimport (testproject12/controllertestproject12/httpServer
)func SetupRoutes(server *httpServer.HTTPServer) {// 添加路由server.AddRoute(/person, controller.PersonHandler)// Add more routes as needed
} tcp篇
用SocketTool新建一个客户端 http://localhost:8080/person 服务器收到数据FFFFFF
总结
实现了http请求与tcp请求如果有需要的话请fork我的github代码
