Scan and Recognize an Image of a Barcode in Go

If you’re lacking a hand-held barcode scanner, you’re not alone. Thankfully, you can easily retrieve information from an image of a barcode using the Barcode Scan iteration of our Barcode API. Take a look below to learn how you can take advantage of this API using code snippets in Go from the Cloudmersive API Console.

Before you get started, you’ll need an API key — head to our website (www.cloudmersive.com) and create a free account with zero commitments to receive one, and gain access to many other APIs with up to 800 API calls per month.

Copy and paste the below into your project:

package mainimport (
"fmt"
"bytes"
"mime/multipart"
"os"
"path/filepath"
"io"
"net/http"
"io/ioutil"
)
func main() {url := "https://api.cloudmersive.com/barcode/scan/image"
method := "POST"
payload := &bytes.Buffer{}
writer := multipart.NewWriter(payload)
file, errFile1 := os.Open("/path/to/file")
defer file.Close()
part1,
errFile1 := writer.CreateFormFile("imageFile",filepath.Base("/path/to/file"))
_, errFile1 = io.Copy(part1, file)
if errFile1 != nil {
fmt.Println(errFile1)
return
}
err := writer.Close()
if err != nil {
fmt.Println(err)
return
}
client := &http.Client {
}
req, err := http.NewRequest(method, url, payload)
if err != nil {
fmt.Println(err)
return
}
req.Header.Add("Content-Type", "multipart/form-data")
req.Header.Add("Apikey", "YOUR-API-KEY-HERE")
req.Header.Set("Content-Type", writer.FormDataContentType())
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))
}
