Images in Blobstore: inefficient to get metadata?

由 纵饮孤独 提交于 2019-12-25 14:38:09
问题 Summary: I'm using Blobstore to let users upload images to be served. I want to prevent users from uploading files that aren't valid images or have dimensions that are too large. I'm using App Engine's Images service to get the relevant metadata. BUT, in order to get any information about the image type or dimensions from the Images service, you have to first execute a transform, which fetches the transformed image to the App Engine server. I have it do a no-op crop and encode as a very low

How to migrate from The Files API to Google Cloud Storage?

由 谁说我不能喝 提交于 2019-12-24 12:23:02
问题 I've got a message yesterday from Google saying that the Files API will be disabled on July 28th and it is recommended to migrate to Google Cloud Storage. Currently I use Files API in the following way - once email is received, I save its attachment (images only) to blobstore - from google.appengine.api import files bs_file = files.blobstore.create(mime_type=ctype, _blobinfo_uploaded_filename='screenshot_'+image_file_name) try: with files.open(bs_file, 'a') as f: f.write(image_file) files

Replacing BlobStore Upload Handler with GCS

由 ﹥＞﹥吖頭↗ 提交于 2019-12-24 07:56:34
问题 I'm looking at replacing our usage of the Blobstore API with GCS, per the recommendation in the Blobstore docs. As far as I can tell, the right way to allow a user to upload a files seems to be to pass them a signed URL where they can upload their data. The piece I'm missing is that the Blobstore API has an UploadHandler, which allows you to perform some actions when a file has been uploaded (e.g. store metadata in a database), and even return a response to the user's upload request. Is there

问题 I'm working on a project in Django nonrel, on Google App Engine, though I have a feeling my problem has nothing to do with either of these directly . I have a hidden field in one of the models that is defined like so: models.CharField(max_length=400, null=True, blank=True,default="{}") The field is meant to receive JSON data from a widget in my admin, and in the client its value changes properly. (Which data is being sent is irrelevant to my problem - whatever string is in the field value is

Delete files from blobstore using file serving URL

由 房东的猫 提交于 2019-12-23 20:45:32
问题 In my app (GWT on GAE) we are storing on our database the serving URL that is stored on blobstore. When user selects one of these files and clicks "delete", we need to delete the file from blobstore. This is our code, but it is not deleting the file at all: public void remove(String fileURL) { BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); String key = getBlobKeyFromURL(fileURL); BlobKey blobKey = new BlobKey(key); blobstoreService.delete(blobKey); } Where
