## Server code
```python
package main
import (

if err := r.ParseForm(); err != nil {
fmt.Fprintf(w, "ParseForm() err: %v", err)
return
}
fmt.Fprintf(w, "POST request successful\n")
name := r.FormValue("name")
address := r.FormValue("address")
fmt.Fprintf(w, "Name = %s\n", name)
fmt.Fprintf(w, "Address = %s\n", address)
}
func helloHandler(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/hello" {
http.Error(w, "404 not found", http.StatusNotFound)
return
}
if r.Method != "GET" {
http.Error(w, "method is not support", http.StatusNotFound)
return
}
fmt.Fprintf(w, "hello!")
}
func main() {
FileServer := http.FileServer(http.Dir("./static"))
http.Handle("/", FileServer)
http.HandleFunc("/form", formHandler)
http.HandleFunc("/hello", helloHandler)
fmt.Println("Starting server at port 8080")
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
