[google-appengine] Re: Advanced Sample for Endpoints?

[Will Merydith]

Bumping this.  Trying to find a sample that shows how one would translate 
NDB objects to Messages in order to work with Endpoints.  It seems like 
this is the most common use case for Endpoints but I cannot find any 
guidance.

[google-appengine] Advanced Sample for Endpoints?

[Will Merydith]

I would love to see a more advanced sample for using Endpoints to build an 
API (in Python on App Engine). Meaning a sample project with multiple 
models, interesting queries and support for all REST methods on each 
collection.

Please reply with a link if you know of any.  Thanks.

Re: [google-appengine] Re: Google App Engine OAuth endpoints throwing 400 in production.

[Will Merydith]

Thanks for the reply Robert.

I ended up spending several hours last night reading through the OAuth specs
and SHA1 specs (in particular how to properly sign a request).  I now have a
much better understanding of the OAuth dance and the Google docs seem much
more clear.

My development partner and I tried out Singpost (for Android), which seems
to work.

Just to be clear, Oauth2 isn't for OAuth2.0, but rather just indicates it's
a second version of oauth?

Re: [google-appengine] Re: Google App Engine OAuth endpoints throwing 400 in production.

[Will Merydith]

OK I have some new information and questions to add to this discussion:

1 - There is some confusion in the documentation over whether registration 
is required or not.

Both here and 
here,
 
it says registration is optional.  Regardless, I have registered my app.

2 - When going through the process of registering your application with 
Google, you're informed that a certificate is not necessary on Google App 
Engine, and that the OAuth signature method is HMAC-SHA1.  Can anyone 
confirm that as the case for using the OAuth for Python?

3- Testing this locally doesn't provide much feedback because no matter what 
you pass, it works.  On appspot, it's the opposite problem because there's 
no information on what failed.  I've tried the OAuth Playground, which is 
great, but wanted to verify that it supports testing OAuth for python.  I am 
using it to test my Request for a Token and it fails, reporting, 
signature_invalid.

The documentation on signature construction is confusing, in some cases it 
indicates sending a base string to the server that is the request url 
encoded, and in other places it seems to be saying that you pass the string 
directly as in: 

oauth_signature="wOJIO9A2W5mFwDgiDvZbTSMK%2FPY%3D"

Can anyone clarify?

Re: [google-appengine] Re: Google App Engine OAuth endpoints throwing 400 in production.

[Will Merydith]

Some questions:

My app is on Google App Engine at http://application-id.appspot.com, and I
have a domain, http://www.application-id.com registered (with Google) and
pointing to the appspot domain.

1) Do I still need to register even though these are both Google registered
domains?
2) Do I register the both the appspot and custom domains?

Thanks for the reply.  I have not registered the app.  I didn't think that
was required when using Google App Engine as the service provider.  I'll
register and test it out.

[google-appengine] Google App Engine OAuth endpoints throwing 400 in production.

[Will Merydith]

(posted in OAuth group as well) 

I implemented the experimental OAuth support for Google App Engine using 
Python,
 
and have it working locally, but the endpoints are throwing a 400 when I 
deploy to appspot.

For example, the url http(s)://my-app.appspot.com/_ah/OAuthGetRequestToken 
returns a 400, but locally that url pattern behaves as expected.

I have tried both http and https, and assumed that appspot handles the ssl 
cert.

Re: [google-appengine] ETA for programmatic creation of Blobstore images?

[Will Merydith]

"provide methods for storing images via path/uri (in addition to the POST
method provided now)"

My understanding is that right now, in terms of storing images, the API only
supports uploading via POST.  It makes it very easy to implement a form for
uploading images, but you cannot save images using say urllib.  For example
I cannot grab CC images from Flickr's API for us in my app.  Correct?

[google-appengine] ETA for programmatic creation of Blobstore images?

[Will Merydith]

I was happy to see that in the App Engine Blog's latest post, a link to the 
technical roadmap says, "Programmatic Blob creation in Blobstore"

It's low on the list, but maybe that does not indicate priority.  Is there 
an ETA on this feature?  I assume this means the API will be updated to 
provide methods for storing images via path/uri (in addition to the POST 
method provided now).
