小编rpu*_*kar的帖子

我想在go中处理一个简单的html表单.但是,我无法在提交后获得任何帖子数据.r.Form地图始终是[].不知道我哪里错了.

提前致谢.

这是代码http://play.golang.org/p/aZxPCcRAVV

package main

import (
    "html/template"
    "log"
    "net/http"
)

func rootHandler(w http.ResponseWriter, r *http.Request) {
    t, _ := template.New("form.html").Parse(form)
    t.Execute(w, "")
}

func formHandler(w http.ResponseWriter, r *http.Request) {
    log.Println(r.Form)
    rootHandler(w, r)
}

func main() {
    http.HandleFunc("/", rootHandler)
    http.HandleFunc("/login", formHandler)
    http.ListenAndServe("127.0.0.1:9999", nil)
}

var form = `
<h1>Login</h1>
<form action="/login" method="POST">
<div><input name="username" type="text"></div>
<div><input type="submit" value="Save"></div>
</form>
`
