go語言建立web伺服器（簡單方便）

package main
import (
    "fmt"
    "log"
    "net/http"
    "strings"
)
func HttpHandle(rw http.ResponseWriter, req *http.Request) {
    req.ParseForm() //解析參數，預設是不會解析的
    for key, val := range req.Form {
        fmt.Println("-------------------------")
        fmt.Println("key:", key)
        fmt.Println("val:", strings.Join(val, ""))
    }
    fmt.Fprintf(rw, "resp hello!")
}
func main() {
    http.HandleFunc("/", HttpHandle)         //設定訪問的路由
    err := http.ListenAndServe(":9080", nil) //設定監聽的連接埠
    if err != nil {
        log.Fatal("ListenAndServe: ", err)
    } 
}
編譯之後運行伺服器端：在瀏覽器輸入：http://localhost:9080/。就會在瀏覽器顯示resp hello!
也可以為伺服器輸入帶參數：http://localhost:9080/?key1=val1&key2=val2&key3=val3
