Go语言获取请求头和请求参数

package main

import "fmt"
import "net/http"

func param(res http.ResponseWriter, req *http.Request) {
   fmt.Fprintln(res, "第一个")
   //req.Header中Header本质是:type Header map[string][]string
   header:=req.Heade
   fmt.Fprintln(res,"Header全部数据:",header)
   //为了让各位同学便读写代码,刻意明确给定类型
   var acc []string =header["Accept"]
   for _,n:=range acc{
      fmt.Fprintln(res,"Accepth内容:",n)
   }
}

func main() {
   server := http.Server{
      Addr: "localhost:8090",
   }
   http.HandleFunc("/param", param)
   server.ListenAndServe()
}

package main

import "fmt"
import "net/http"

func param(res http.ResponseWriter, req *http.Request) {
    req.ParseForm()
    fmt.Fprintln(res,req.Form)
    /*
    按照请求参数名获取参数值
    根据源码,FormValue(key)=req.Form[key]
     */
    name:=req.FormValue("name")
    age:=req.FormValue("age")
    fmt.Fprintln(res,name,age)
}

func main() {
    server := http.Server{
        Addr: "localhost:8090",
    }
    http.HandleFunc("/param", param)
    server.ListenAndServe()
}
