[tangzero]

outputs a code with better and idiomatic error handling

Get example:

package main

import (
	"fmt"
	"io/ioutil"
	"net/http"
	"os"
)

func sendGetItem() error {
	// Get Item (GET https://api.mercadolibre.com/items/MLB1017718623)


	// Create request
	req, err := http.NewRequest("GET", "https://api.mercadolibre.com/items/MLB1017718623", nil)
	if err != nil {
		fmt.Fprintln(os.Stderr, err)
		return err
	}

	// Fetch Request
	resp, err := http.DefaultClient.Do(req)
	if err != nil {
		fmt.Fprintln(os.Stderr, err)
		return err
	}
	defer resp.Body.Close()

	// Read Response Body
	respBody, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		fmt.Fprintln(os.Stderr, err)
		return err
	}

	// Display Results
	fmt.Println("response Status : ", resp.Status)
	fmt.Println("response Headers : ", resp.Header)
	fmt.Println("response Body : ", string(respBody))

	return nil
}
