Convert Image that reside at a url to base64 encoded string

Pleae help in converting an image that resides at url path on aws bucket to base64 encoded string.

Try this:
b64 “encoding/base64” ->

In this example I’m already decreasing the image size

file, _, err := req.FormFile("image")
			if err != nil {
				http.Error(w, err.Error(), http.StatusInternalServerError)
			defer file.Close()
			img, _, err := image.Decode(file)
			m := resize.Resize(135, 115, img, resize.Lanczos3)
			buf := new(bytes.Buffer)
			err = jpeg.Encode(buf, m, &jpeg.Options{35})
			imageBit := buf.Bytes()
			/*Defining the new image size*/

			photoBase64 := b64.StdEncoding.EncodeToString([]byte(imageBit))
			fmt.Println("Photo Base64.............................:" + fotoBase64)
