go 练习：HTTP 处理

这篇文章只是联系go指南时的笔记吧。

package main

import (
	"fmt"
	"log"
	"net/http"
)

type String  string

type Struct struct{
	Greeting string
	Punct string
	Who string
}

func main(){
	http.Handle("/string",String("aaaaaaaaaaaaaaaaaaaa2"))
	http.Handle("/struct", Struct{
		Greeting: "Hello",
		Punct:    "",
		Who:      "gopher",
	})
	log.Fatal(http.ListenAndServe("localhost:4000",nil))
}

func (s String) ServeHTTP(w http.ResponseWriter, r *http.Request){
	fmt.Fprint(w,s)
}
func (s Struct) ServeHTTP(w http.ResponseWriter, r *http.Request){
	fmt.Fprint(w,s)
}

　　上面的http.handle() 里面的url，如果重复的话，会报错
