如果该对象是公开可读的，则可以直接在" https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME "，在您的情况下为https://www.googleapis.com/download/storage/v1/b/image-downloader-bucket/o/a06266f6-6082-468e-92ca-f918a48533a8?generation=1455661996337000&alt=media

Can someone let me know how to create the right URL for viewing the image ?

If the object is publicly readable, you can view it directly at "https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME", which in your case would be https://storage.googleapis.com/image-downloader-bucket/a06266f6-6082-468e-92ca-f918a48533a8.
