Functions

func Routes

func Routes()

Routes sets the routes for the web service. It has 1 route call sendjson. When that route is executed, it will call the SendJSON function.

func SendJSON

func SendJSON(rw http.ResponseWriter, r *http.Request)

SendJSON returns a simple JSON document. This has the same signature that we had before using ResponseWriter and Request. We create an anonymous struct, initialize it and unmarshall it into JSON and pass it down the line.

Example

ExampleSendJSON provides a basic example example. Notice that we are binding that Example to our SendJSON function.

package main

import (
	"encoding/json"
	"fmt"
	"log"
	"net/http"
	"net/http/httptest"
)

func main() {
	r := httptest.NewRequest("GET", "/sendjson", nil)
	w := httptest.NewRecorder()
	http.DefaultServeMux.ServeHTTP(w, r)

	var u struct {
		Name  string
		Email string
	}

	if err := json.NewDecoder(w.Body).Decode(&u); err != nil {
		log.Println("ERROR:", err)
	}

	fmt.Println(u)
}
