1.创建一个登陆交互的的html文件
# login.html <html> <head> <title>login</title> </head> <body> <form action="http://127.0.0.1:9090/login" method="post"> 用户名：<input type="text" name="username"> 密码：<input type="password" name="password"> <input type="submit" value="登陆"> </form> </body> </html>
2.后端处理逻辑
package main import ( "fmt" "html/template" "log" "net/http" "strings" ) func sayhelloname(w http.ResponseWriter, r *http.Request) { r.ParseForm() //解析参数,默认是不会解析的。 fmt.Println(r.Form) 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("value:", strings.Join(v, ",")) } fmt.Fprintf(w, "hello, welcome you!") //这个字符串写入到w中，用于返回给客户端。 } func login(w http.ResponseWriter, r *http.Request) { fmt.Println("method: ", r.Method) if r.Method == "GET" { t, _ := template.ParseFiles("login.html") t.Execute(w, nil) } else { r.ParseForm() fmt.Println("username: ", r.Form["username"]) fmt.Println("password:", r.Form["password"]) } } func main() { http.HandleFunc("/", sayhelloname) //设置访问的路由 http.HandleFunc("/login", login) //设置访问的路由 err := http.ListenAndServe(":9090", nil) //设置监听的端口 if err != nil { log.Fatal("ListenAndServe: ", err) } }
请复制代码自行测试。
