问题 How to play(stream instead of download) a video file stored in GCS? The file was stored using Blobstore API in GAE Python? Presently, the video gets downloaded when I use the url, returned by send_blob, in the frontend. I serve the video using: video_url = "/v?video_id="+video_blobkey :: class GCSFileServe(blobstore_handlers.BlobstoreDownloadHandler): def get (self): blob_key = self.request.get('video_id') self.send_blob(blob_key) :: app = webapp2.WSGIApplication([ ('/', MainHandler), ('/v',

问题 I'm trying to build a simple Golang/Appengine app which uses a channel to handle each http request. Reason is I want each request to perform a reasonable large in- memory calculation, and it's important that each request is performed in a thread- safe manner (ie calculations from concurrent requests don't get mixed). Essentially I need a synchronous queue which will only process one request at a time, and channels look like a natural fit. Is it possible to use Go's buffered channel as a

问题 I've been unable to find any concrete documentation on how to use Cloud Storage from an Android application. I did come across this client library from the Google Cloud SDK, however have run into many, many issues and have yet to get it working.

问题 I'm using Google App Engine with PHP. I want all HTML files in the folder Client_Pages to be recognized and served as static files, and all the PHP files in the same folder to be recognized and served as script files. Here is what the app.yaml file looks like: application: myappname version: 1 runtime: php api_version: 1 threadsafe: true handlers: - url: / script: index.php - url: /Client_Pages/*.php script: /Client_Pages/*.php - url: /Client_Pages/*.html static_dir: Client_Pages/*.html I

问题 I've used this question as a template to solve the same problem, but I'm running into issues when posting. I have these components: HTML form with a textbox for the image URL. This posts to... A handler that takes the posted URL, encodes it, and uses urlfetch to post it again to... A separate file upload handler that does the actual saving. Component #3 works fine by itself if I use a file input. But I don't quite understand how to get urlfetch what it needs from just the image URL. My

问题 I have implemented the python code here below based on the documentation in order to access a spreadsheet accessible through a public link. It works once every hour. If I execute a few seconds after a success, I receive an error : Error opening spreadsheet no element found: line 1, column 0 Assumption: The access token has an expiry date of 1 hour. So the appengine would proceed to a token refresh after an hour, resetting the whole. Question: This code requests a new token for each request.
