i've created a new example here, https://github.com/lholmquist/ag-google-drive

that hopefully shows the flow a bit

this time i added a pipe object and used pipe.read to see how the flow would be

ok,  Kris had some thoughts on a better flow, so i refactored the code a bit and i think i like this way a bit better.  

New Flow - Client Flow - Standalone for now, possible integration with pipes

First Time - No Access Token stored( in localStorage )

User will create the Authorization Object stuff with settings/options

var thing = AeroGear.Authorization();

thing.add({
    name: "coolThing",
    settings: {
        clientId: "12345.apps.googleusercontent.com",
        redirectURL: "http://localhost:8000/redirector.html",
        tokenValidationEndpoint: "https://www.googleapis.com/oauth2/v1/tokeninfo",
        authEndpoint: "https://accounts.google.com/o/oauth2/auth",
        revokeURL: "https://accounts.google.com/o/oauth2/revoke",
        scopes: "https://www.googleapis.com/auth/userinfo.profile",
        prompt: "force"
    }
});

should have the ability to specify more settings, based on the spec

The user would then call some method( currently not good names are coming to me, maybe validate ) that takes success and error callbacks.

thing.services.coolThing.validate({
    success: function( response ){
        console.log( "Should be response from Validating the access token", response );
    },
    error: function( error ) {
        //should contain a constructed URL for the user
        console.log( "error", error );
    }
});

Since this is the first time, the error callback will be called and will contain the constructed URL that the user should do the popup redirect dance with to get an access token.

what "dance" they do is up to the developer

Once that happens and they have the access token, they would call the validate method again.

this makes sure that the token they recieved is validated and will also return some other meta data related to the token, like refresh time.

Once the token has been validated, it will be stored in localStorage and would be accessable with the key of ag-oauth2-whatever_the_client_ID_is .

so in this example it would be something like:

ag-oauth2-12345.apps.googleusercontent.com

There is one problem i can see here though. If the user has to applications with the same client ID but different scopes assigned, this would be a problem. That use case could be considered bad practice anyway

The user can then call the "callService"( yes, again, crappy name ) method to get access to the service they want.

thing.services.coolThing.callService({
    serviceURL: "https://www.googleapis.com/oauth2/v2/userinfo",
    success: function( response ){
        console.log( "Should be the response from the call", response );
    },
    error: function( error ) {
        console.log( "error", error );
    }
});

All these methods would have success/error callbacks.

Token Expiration

If the user makes a call to a service, using the callService method, and they recieve an error such as not authorized or token invalid or token expired, I'm thinking we send what the "contructed URL" should be, similar to the validate method described above.

Since this is a Client Side flow, there is no refresh token, so the client wouldn't be able to refresh the access token without doing the "dance" again.

it is still very rough

Hi,
That sounds good !
Just one question, instead of using the callApi function couldn't we
pass the oauth module (called 'thing' in your example) to the pipe
directly, using the 'authenticator' setting. Behind the scene, the
pipe manager will append the oauth token to the query or add the
bearer header ?

I'm not sure if that is what this is going to do.  This is more of an
Authorization thing and i don't think it totally fits the pipeline
stuff. ( or it would make it a bit more complicated, and we want to keep
it simple )


i should probably change the method to be "authorize" instead

       OAuth2 AeroGear Workflow - High Level


         Using Google api's

   /Server Side/

    1. user needs to first create an "application/project" to get an
       api key
    2. Then they would choose the services/api's then would like
       there application to access
    3. other google server related items....

   /Client Side/

    1. Create a new OAuth2 module thing
    2. Get access token for the services would need to specify the
       services they would like to access
    3. validate the token
    4. make calls to the service


         API

   |var thing = AerGear.OAuth2({
                   name: googleEndPoints, //Just a Name
                   clientID: "12345" //The client ID of the app from the API console
                   settings: {
                       permissions: "..",
                       ...
                   }
               }).somecoolmodulename.googleEndPoints;
   |

   /Settings: Multiple settings based on paramters here
   <https://developers.google.com/accounts/docs/OAuth2UserAgent>/

   /Methods/


         authenticate

   this will authenticate with the server to get the access token and
   then validate the token, once that is all good then the response
   is returned.

   |thing.authenticate({
       success:{},
       error:{},
       settings: {
           //probably some settings here, like URL overides and such
       }
   });
   |


         callApi

   not really a good name, but it would basically call the remote
   api/services. we could either do a query string option or a Head
   option

   example:

   |curl 'https://www.googleapis.com/oauth2/v1/userinfo?access_token=1/fFBGRNJru1FQd44AzqT3Zg'
   |

   or

   |curl -H "Authorization: Bearer {accessToken}" https://www.googleapis.com/oauth2/v1/userinfo
   |

   code:

   |thing.callApi({
       service: "userinfo", //don't really like this name either
       success:{},
       error:{},
       settings: {
           ... //overridable baseURLs?
       }
   });
   |


         revoke

   again, maybe not the best name. calls the "revoke" service, to
   remove access to permissions

   |thing.revoke({
       success: {},
       error: {},
       settings: {}
   });
   |

   Behind the scenes on all these calls, the "access_token" is
   beining used and possibly refreshed for the user, so they don't
   have to worry about it. They just need to call authenticate first.
   Maybe we can have a refresh method if the user wants to refresh
   the tokens themselves. this would do the token "dance"

   I think and authorization API that basically just wraps itself
   around secured endpoints works for me.
