oauth2: auto-detect auth style by default, add Endpoint.AuthStyle

Instead of maintaining a global map of which OAuth2 servers do which
auth style and/or requiring the user to tell us, just try both ways
and remember which way worked. But if users want to tell us in the
Endpoint, this CL also add Endpoint.AuthStyle.

OAuth2 for Go

Build Status GoDoc

oauth2 package contains a client implementation for OAuth 2.0 spec.

Installation

go get golang.org/x/oauth2

Or you can manually git clone the repository to $(go env GOPATH)/src/golang.org/x/oauth2.

See godoc for further documentation and examples.

App Engine

In change 96e89be (March 2015), we removed the oauth2.Context2 type in favor of the context.Context type from the golang.org/x/net/context package. Later replaced by the standard context package of the context.Context type.

This means it‘s no longer possible to use the “Classic App Engine” appengine.Context type with the oauth2 package. (You’re using Classic App Engine if you import the package "appengine".)

To work around this, you may use the new "google.golang.org/appengine" package. This package has almost the same API as the "appengine" package, but it can be fetched with go get and used on “Managed VMs” and well as Classic App Engine.

See the new appengine package's readme for information on updating your app.

If you don't want to update your entire app to use the new App Engine packages, you may use both sets of packages in parallel, using only the new packages with the oauth2 package.

import (
	"context"
	"golang.org/x/oauth2"
	"golang.org/x/oauth2/google"
	newappengine "google.golang.org/appengine"
	newurlfetch "google.golang.org/appengine/urlfetch"

	"appengine"
)

func handler(w http.ResponseWriter, r *http.Request) {
	var c appengine.Context = appengine.NewContext(r)
	c.Infof("Logging a message with the old package")

	var ctx context.Context = newappengine.NewContext(r)
	client := &http.Client{
		Transport: &oauth2.Transport{
			Source: google.AppEngineTokenSource(ctx, "scope"),
			Base:   &newurlfetch.Transport{Context: ctx},
		},
	}
	client.Get("...")
}

Policy for new packages

We no longer accept new provider-specific packages in this repo. For defining provider endpoints and provider-specific OAuth2 behavior, we encourage you to create packages elsewhere. We'll keep the existing packages for compatibility.
