Golang : Gorilla web tool kit schema example
This is an example on how to use Gorilla web tool kit Schema package. The Schema package is very useful in mapping data from Form into objects(struct).
Here you go!
package main
import (
"fmt"
"github.com/gorilla/mux"
"github.com/gorilla/schema"
"net/http"
)
type Person struct {
Name string
Phone string
}
func GetFormDataHandler(w http.ResponseWriter, r *http.Request) {
html := `<h1>Contact : </h1>
// replace example.com to your machine domain name or localhost
<form action="http://example.com:8080/process_form_data" method="post">
<div>
<label>Name : </label>
<input type="text" name="name" id="name" >
</div>
<div>
<label>Phone : </label>
<input type="text" name="phone" id="phone" >
</div>
<div>
<input type="submit" value="Send">
</div>
</form>`
w.Write([]byte(fmt.Sprintf(html)))
}
func ReadFormDataHandler(w http.ResponseWriter, r *http.Request) {
err := r.ParseForm()
if err != nil {
fmt.Println(err)
}
person := new(Person)
decoder := schema.NewDecoder()
err = decoder.Decode(person, r.PostForm)
if err != nil {
fmt.Println(err)
}
fmt.Println(person)
w.Write([]byte(fmt.Sprintf("Name is %v \n", person.Name)))
w.Write([]byte(fmt.Sprintf("Phone is %v \n", person.Phone)))
}
func main() {
mx := mux.NewRouter()
mx.HandleFunc("/", GetFormDataHandler)
mx.HandleFunc("/process_form_data", ReadFormDataHandler)
http.ListenAndServe(":8080", mx)
}
Run the code and point your browser to the main page i.e localhost:8080, key in the data and press the "Send" button.
