1)通過模板方法渲染登錄頁面。 例:這是index.html的GO:如何將數據發佈到數據存儲?
{{ define "title" }}Guestbook{{ end }}
{{ define "content" }}
<form action="/login" method="post">
<div><label>UserName : </label><input name="username" type="text" /></div>
<div><label>Password : </label><input name="password" type="password" /></div>
<div><input type="submit" value="login"></div>
</form>
{{ end }}
2)hello.go文件:
package main
import (
"fmt"
"html/template"
"net/http"
)
var index = template.Must(template.ParseFiles(
"templates/base.html",
"templates/index.html",
))
type UserLogin struct{
UserName string
PassWord string
}
func handler(w http.ResponseWriter, r *http.Request) {
index.Execute(w, nil)
}
/*func login(w http.ResponseWriter, r *http.Request) {
remPartOfURL := r.URL.Path[len("/login/"):]
if r.Method == "POST" {
fmt.Fprintf(w, "after",r.FormValue("username"))
}
fmt.Fprintf(w, "Hello %s!", remPartOfURL)
}*/
func login(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "login : ", "\n")
remPartOfURL := r.URL.Path[len("/login/"):]
if r.Method == "POST" {
g := UserLogin{
UserName: r.FormValue("username"),
PassWord: r.FormValue("password"),
}
fmt.Fprint(w, "&g : ", &g,"\n")
}
fmt.Fprintf(w, "Hello %s!", remPartOfURL)
}
func init() {
http.HandleFunc("/", handler)
http.HandleFunc("/login/", login)
}
問題:點擊登錄按鈕後:&摹應打印的用戶名和密碼值卻是露出空:& g:& {} 可以做些什麼?
更改問題和代碼不好,焦點不準! 將其更改爲:'fmt.Fprint(w,「%#v:」,g,「\ n」)' –
