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,
}
