使用golang实现简单的http服务器

方式1

package main
import (
    "fmt"
    "net/http"
)

func main(){
    //处理路由为 / 的方法
    http.HandleFunc("/",func(w http.ResponseWriter,r *http.Request){
        fmt.Fprintln(w,"Hello World",r.URL.Path)
    })
    //监听3000端口
    http.ListenAndServe(":3000",nil) 
}

方式2

package main
import (
    "fmt"
    "net/http"
)
type MyHandler struct{

}
//实现接口的ServeHTTP方法
func (this *MyHandler) ServeHTTP(w http.ResponseWriter, r *http.Request){
    fmt.Fprintln(w,"通过实现接口Handler的ServeHTTP方法来创建服务器")
}


func main(){
    myHandler := &MyHandler{}
    http.Handle("/",myHandler)
    http.ListenAndServe(":8888",nil)
}
