Go编程基础4-Http服务器

1、http服务器

package main
import(
    "net/http"
    "log"
)
func main(){//注册某个函数专门响应某个路由"/"，函数签名符合
    http.HandleFunc("/",func(w http.ResponseWriter,r *http.Request){
        w.Write([]byte("Hello,this is version 1!"))
    })
    http.HandleFunc("/bye",sayBye)
    log.Println("Starting server ... v1")
    log.Fatal(http.ListenAndServe(":4000",nil))
}
func sayBye( w http.ResponseWriter,r *http.Request){
    w.Write([]byte("Bye bye,this is version 1!"))
}
go run test.go
