ParseForm 填充r.Form和r.PostForm。For all requests,
ParseForm parses the raw query from the URL 和 updates r.Form.用户提交的表单详细信息存储在2个变量名称和地址中。
HTML表单有2个输入框的名称和地址。
创建两个不同的文件 form.html 和 main.go
<!DOCTYPE html> <html> <head> <meta charset="UTF-8" /> </head> <body> <div> <form method="POST" action="/"> <label>Name</label><input name="name" type="text" value="" /> <label>Address</label><input name="address" type="text" value="" /> <input type="submit" value="submit" /> </form> </div> </body> </html>
package main
import (
"fmt"
"log"
"net/http"
)
func hello(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
http.Error(w, "404 not found.", http.StatusNotFound)
return
}
switch r.Method {
case "GET":
http.ServeFile(w, r, "form.html")
case "POST":
// Call ParseForm() to parse the raw query 和 update r.PostForm 和 r.Form.
if err := r.ParseForm(); err != nil {
fmt.Fprintf(w, "ParseForm() err: %v", err)
return
}
fmt.Fprintf(w, "Post from website! r.PostFrom = %v\n", r.PostForm)
name := r.FormValue("name")
address := r.FormValue("address")
fmt.Fprintf(w, "Name = %s\n", name)
fmt.Fprintf(w, "Address = %s\n", address)
default:
fmt.Fprintf(w, "Sorry, only GET 和 POST methods are supported.")
}
}
func main() {
http.HandleFunc("/", hello)
fmt.Printf("Starting server for testing HTTP POST...\n")
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}
