如果你正在使用net/http包：
package main
import (
"fmt"
"log"
"net/http"
)
func login(w http.ResponseWriter, r *http.Request) {
err := r.ParseForm()
if err != nil {
log.Fatal(err)
}
email := r.PostForm.Get("email")
password := r.PostForm.Get("password")
finalValue := fmt.Sprintf("%s 和 %s", email, password)
fmt.Fprintln(w, finalValue)
}
func main() {
http.HandleFunc("/login", login)
err := http.ListenAndServe(":8080", nil)
if err != nil {
log.Fatal("启动HTTP服务器时出错：", err)
return
}
}

If you are using net/http
package main

func login(w http.ResponseWriter, r *http.Request) {
err := r.ParseForm()
if err != nil {
log.Fatal(err)
}
// fmt.Fprintln(w, "Email : ", r.PostForm.Get("email"))
// fmt.Fprintln(w, "Password : ", r.PostForm.Get("password"))
email := r.PostForm.Get("email")
password := r.PostForm.Get("password")
finalValue := fmt.Sprintf("%s and %s", email, password)
// fmt.Println(finalValue)
fmt.Fprintln(w, finalValue)
}
func main() {
http.HandleFunc("/login", login)
err := http.ListenAndServe(":8080", nil)
if err != nil {
log.Fatal("Error Starting the HTTP Server : ", err)
return
}
}
