golang搭建一个网站只是需要简单的几句就可以了

package mainimport ("fmt""log""net/http""strings")func sayhelloName(w http.ResponseWriter, r *http.Request) {r.ParseForm() //解析参数，默认是不会解析的fmt.Println(r)fmt.Println(r.Form) //这些信息是输出到服务器端的打印信息fmt.Println("path", r.URL.Path)fmt.Println("scheme", r.URL.Scheme)fmt.Println(r.Form["url_long"])for k, v := range r.Form {fmt.Println("key:", k)fmt.Println("val:", strings.Join(v, ""))}fmt.Println("love is ", r.Form["love"])fmt.Fprintf(w, "Hello astaxie!\n love the way you lie\n", strings.Join(r.Form["love"], "")) //这个写入到w的是输出到客户端的}func main() {http.HandleFunc("/hi", sayhelloName)     //设置访问的路由err := http.ListenAndServe(":9999", nil) //设置监听的端口if err != nil {log.Fatal("ListenAndServe: ", err)}}

访问路径 http://localhost:9999/hi?love=peixuan

浏览器显示

Hello astaxie! love the way you lie%!(EXTRA string=peixuan)

服务器输出

&{GET /hi?love=peixuan HTTP/1.1 1 1 map[Connection:[keep-alive] Accept:[text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8] User-Agent:[Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36] Accept-Encoding:[gzip,deflate,sdch] Accept-Language:[zh-CN,zh;q=0.8] Cookie:[bdshare_firstime=1408295027879; CNZZDATA1000303351=1033954442-1408293709-%7C1411104049; CNZZDATA1252923572=1884016693-1411953884-%7C1411953884]] 0x896c30 0 [] false localhost:9999 map[love:[peixuan]] map[] <nil> map[] 127.0.0.1:42473 /hi?love=peixuan <nil>}

map[love:[peixuan]]

path /hi

scheme

[]

key: love

val: peixuan

love is [peixuan]

暂时先存个档，后期慢慢丰富。
