问题 To verify a SSL certificate, I need to upload a hidden folder ("/.well-known" containing some files to my application. I am deploying java application with eclipse, but these files do not receive at the application on appengine. I guess they are filtered out. I tried to add the hidden folder as static file to the appengine-web.xml, but it did not help. <!-- Configure serving/caching of GWT files --> <static-files> <include path="**" /> <include path=".**" /> <include path="**.*" expiration=

问题 I have a Java ClientRequest to the Google API that returns a json containing the profile based in an access_token. The URL is: https://www.googleapis.com/oauth2/v1/userinfo?access_token=ya29.1.AADtN_VALuuUTBm8ENfNTz8s... And the response is: { "id": "111223344556677889900", "email": "myemail@gmail.com", "verified_email": true, "name": "My Name", "given_name": "My", "family_name": "Name", "link": "plus.google.com/111223344556677889900", "picture": "photo.jpg", "gender": "male", "locale": "en"

问题 Since Google App Engine will soon full support Java: Would it be possible to run Ruby on Rails on Google App Engine? Or the limitations imposed by the AppEngine runtime will affect the JRuby implementation? What about other languages such as Groovy, Clojure, Scheme? Are there any effort to support .net and C# in JVM?? I think this would create a NEXT level on webdevelopment. 回答1: This is already possible. Its not perfect, but I would expect rapid improvement.

问题 I'm using Google App Engine with their webapp framework. Is there something like Django's ForeigKey in webapp ? i.e. I have a model and I want it to have a property/field that points at another model. Possible? 回答1: There is a db.ReferenceProperty. You need to be aware of two things when using it: automatic dereferencing (which is another datastore RPC call) and the entity being referenced is not required to exist (so you will need to manually check it). When using db.ReferenceProperty make

问题 Hopefully Moishe sees this: in development mode, the channel api client (javascript) resorts to polling... and uses a very fast polling rate. After poking around I found that if I set goog.appengine.Socket.POLLING_TIMEOUT_MS = interval; I can control the polling rate. What I'm wondering is: How do I know if/when the client is going to go into "poll mode" in production? Is it possible to force the client into "poll mode"? What happens if I reach the channel quota for my app? will the /_ah

问题 I was trying to run a profiler on some handler code up on appspot and was looking for a way to show the pstats output without writing directly to the response body (which is problematic for handlers responding with structured data such as JSON). I decided to try writing the output to the response header, and added some js to my html-rendering handlers that could parse the header and console.log() it (turned out to be pretty simple and convenient to work with). For the non-html rendering

问题 I am deploying my Nodejs sample app to Google App Engine Flexible env and when I am using google app engine URL which is in the form appspot.com to hit my API, it is taking around 11 secs to send response from my mobile data , but other APIs are sending response in milisecs. Also, the time delay is only happening when I am opening my android app and sending request to the server after that all requests are taking normal time, and again delay is coming when I again open the app and send
