beego3---gohttp底层实现

package main//gohttp底层实现,通过gohttp不是通过beego实现的输出//import ( ???"io" ???"log" ???"net/http")func main() { ???//设置路由 ???http.HandleFunc("/", sayHello) ???err := http.ListenAndServe(":8080", nil) ???if err != nil { ???????log.Fatal(err) ???}}func sayHello(w http.ResponseWriter, r *http.Request) { ???io.WriteString(w, "hello vwesion1")}

package main//gohttp第二个版本：通过mux,handler实现路由import ( ???"io" ???"log" ???"net/http")func main() { ???mux := http.NewServeMux() ?????//ServeMux//实现handler注册到ServeMux然后在进行路由的注册 ???mux.Handle("/", &myHandler{}) ?//注册路由和handler ???mux.Handle("/hello", sayHello) //通过函数注册路由 ???err := http.ListenAndServe(":8080", mux) ???if err != nil { ???????log.Fatal(err) ???}}type myHandler struct { //这个handle要实现ServerHTTP方法}func (this *myHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { ???io.WriteString(w, "hello vwesion2，"+r.URL.String())}func sayHello(w http.ResponseWriter, r *http.Request) { ???io.WriteString(w, "hello vwesion2，"+r.URL.String())}
