How to get public link for the uploaded file on google cloud storage in local dev server(Google App engine+JAVA) -


i trying upload image files using gcs client library+java in local google app engine dev server. images uploaded , can see entries created in local datastore under localhost:8888/_ah/admin/datastore

how public key uploaded images can show images in application. example profile pic.

sample copy of code:

 string filepath = constants.gcsurl + "/" + bucketname + "/"+ objectname;  gcsservice gcsservice = gcsservicefactory                 .creategcsservice(new retryparams.builder()                         .initialretrydelaymillis(10).retrymaxattempts(10)                         .totalretryperiodmillis(15000).build());         gcsfilename filename = new gcsfilename(bucketname, objectname);         gcsfileoptions options = new gcsfileoptions.builder()                 .addusermetadata("cache-control",                         "max-age=" + (86400 * 365)).mimetype(mimetype)                 .acl(acl_public_read).build();         gcsoutputchannel writechannel = gcsservice.createorreplace(                 filename, options);         writechannel.write(bytebuffer.wrap(filebytes));         writechannel.close();

you can use images service on local devserver. need blobkey:

blobstoreservice blobstore = blobstoreservicefactory.getblobstoreservice(); blobkey blobkey = blobstore.creategsblobkey("/gs/" + filename.getbucketname() + "/" + filename.getobjectname())); // blobkey can persisted imagesservice imagesservice = imagesservicefactory.getimagesservice(); string url = imagesservice.getservingurl(servingurloptions.builder.withblobkey(image));

resizing works on local devserver appending =sxxxx, can't native image size - on production, appending =s0 url gets original image, doesn't work locally.
