## App Engine
|
|
|
|
In change 96e89be (March 2015) we removed the `oauth2.Context2` type in favor
|
|
of the [`context.Context`](https://golang.org/x/net/context#Context) type from
|
|
the `golang.org/x/net/context` package
|
|
|
|
This means its 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](https://github.com/golang/appengine#updating-a-go-app-engine-app)
|
|
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 (
|
|
"golang.org/x/net/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("...")
|
|
}
