Why getting err: EOF whereas decoding responce physique into struct – Code Overview

I’ve the under code that fetch some date from server, and put the info right into a struct.

The info is fetched appropriately, however I’m getting err: EOF as an error whereas decoding the returned information into struct:

bundle major

import (
	"encoding/json"
	"fmt"
	"io/ioutil"
	"log"
	"internet/http"
)

kind SKUcard struct {
	BarCode, SKUCode, VendorCode, RegistrationDate, VendorName, BrandName, ContactPerson,
	ContactNumber, ItemName, ItemImage, NetWeight, CartoonPack, StorageTemperature, ShelfLife,
	ShelfPrice, KottofCost, SupplyType, CoveredAreas, MinimumOrderQty, ContractDate, ReturnPolicy, Notes, InActive string
}

func major() {
	req, _ := http.NewRequest("GET", "https://script.google.com/macros/s/AKfycbzw0TKWycxeB5sx1wIefAiEHeYQt2mVuM-NAZTccxedhyntdv8FvcUteOZ2k03wRHGE/exec?", nil)

	q := req.URL.Question()
	q.Add("barcode", "6287029390129")
	//q.Add("another_thing", "foo & bar")
	req.URL.RawQuery = q.Encode()

	fmt.Println(req.URL.String())

	// resp, err := http.Get(req.URL.String())
	resp, err := http.DefaultClient.Do(req)
	_ = req.URL.RawQuery
	if err != nil {
		log.Fatalln(err)
	}

	//We Learn the response physique on the road under.
	physique, err := ioutil.ReadAll(resp.Physique)
	if err != nil {
		log.Fatalln(err)
	}
	//Convert the physique to kind string
	sb := string(physique)
	log.Printf(sb)

	var goal = new(SKUcard)
	err = json.NewDecoder(resp.Physique).Decode(goal)
	if err != nil {
		fmt.Println("err:", err)
	}
	log.Printf(goal.BarCode)
}

From what I see you learn twice from the Physique

• ioutil.ReadAll(resp.Physique)
• json.NewDecoder(resp.Physique)

since Physique is a ReadCloser IMHO the second time you’ll discover it already learn.

So, both:

• take away the primary learn ioutil.ReadAll
• use the json decoder on a learn buffer initialized to physique

buf := bytes.NewBuffer(physique)
err = json.NewDecode(buf).Decode(goal)

as a facet notice I at all times counsel to examine the StatusCode of the response earlier than do physique processing
