内容简介:本文首先介绍使用http标准库搭建web服务,共三种方式,然后简析内部实现原理,最后对http的使用做出总结。阅读本文需要简单的go基础知识和web开发相关知识。
func main() { server := http.Server{ Addr: "127.0.0.1:8081", Handler: &helloHandler{}, } _ = server.ListenAndServe() } type helloHandler struct{} func (h *helloHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { _, _ = fmt.Fprintf(w, "hello World") } 复制代码
func main() { server2 := http.Server{ Addr: "127.0.0.1:8082", } http.Handle("/hello", &helloHandler{}) http.Handle("/hi", &hiHandler{}) _ = server2.ListenAndServe() } type helloHandler struct{} func (h *helloHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { _, _ = fmt.Fprintf(w, "hello World") } type hiHandler struct{} func (h *hiHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) { _, _ = fmt.Fprintf(w, "hi World") } 复制代码
mux := http.NewServeMux() mux.Handle("/hello", &helloHandler{}) mux.Handle("/hi", &hiHandler{}) server2 := http.Server{ Addr: "127.0.0.1:8082", Handler:mux, } 复制代码
func main() { server3 := http.Server{ Addr: "127.0.0.1:8083", } http.HandleFunc("/hello", helloFunc) http.HandleFunc("/hi", hiFunc) _ = server3.ListenAndServe() } func helloFunc(w http.ResponseWriter, r *http.Request) { _, _ = fmt.Fprintf(w, "hello World") } func hiFunc(w http.ResponseWriter, r *http.Request) { _, _ = fmt.Fprintf(w, "hi World") } 复制代码
mux := http.NewServeMux() mux.HandleFunc("/hello",helloFunc) mux.HandleFunc("/hi",hiFunc) server3 := http.Server{ Addr: "127.0.0.1:8083", Handler:mux, } 复制代码
