How to Lookup an EAN Barcode Value & Return Product Data Using Go

Many European retail products are identifiable by their EAN barcode values (most often 8 or 13 digits long). Easily incorporate the EAN barcode lookup iteration of our Barcode API into your project with code samples in Go copied below for your convenience. Before you get started, make sure you have a Cloudmersive API key handy — you can easily get one by creating a free account on our website (www.cloudmersive.com). That’ll also grant you 800 monthly API calls with access to dozens of other useful APIs on the Cloudmersive API Console.

Incorporate the below code into your Go project and incorporate the EAN value where indicated:

package main
import (
     "fmt"
     "strings"
     "net/http"
     "io/ioutil"
)
func main() {
url := "https://api.cloudmersive.com/barcode/lookup/ean"
     method := "POST"
payload := strings.NewReader("0=%3C&1=s&2=t&3=r&4=i&5=n&6=g&7=%3E")
client := &http.Client {
     }
     req, err := http.NewRequest(method, url, payload)
if err != nil {
          fmt.Println(err)
          return
     }
     req.Header.Add("Content-Type", "application/x-www-form-urlencoded")
     req.Header.Add("Apikey", "YOUR-API-KEY-HERE")
res, err := client.Do(req)
     if err != nil {
          fmt.Println(err)
          return
     }
     defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
     if err != nil {
          fmt.Println(err)
          return
     }
     fmt.Println(string(body))
}
