golang學習筆記[4] 網絡編程

golang搭建一個網站只是需要簡單的幾句就可以了

package main

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

func sayhelloName(w http.ResponseWriter, r *http.Request) {
	r.ParseForm() //解析參數，默認是不會解析的
	fmt.Println(r)
	fmt.Println(r.Form) //這些信息是輸出到服務器端的打印信息
	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"], "")) //這個寫入到w的是輸出到客戶端的
}

func main() {

	http.HandleFunc("/hi", sayhelloName)     //設置訪問的路由
	err := http.ListenAndServe(":9999", nil) //設置監聽的端口
	if err != nil {
		log.Fatal("ListenAndServe: ", err)
	}

}

訪問路徑   http://localhost:9999/hi?love=peixuan

瀏覽器顯示

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

服務器輸出
