Use local registry in test fixtures to prevent collision in globally
shared models.
Fix issues discoverd in auth implementation where the global registry
was used instead of the correct local one.
Subsequent token middleware tries to read `token.id`
when `enableDoublecheck: true`.
That caused a "Cannot read property `id` of `null`" error
when the first middleware didn't actually find a valid accessToken.
[back-port of #2227]
Add two new options:
- When `enableDoublecheck` is true, the middleware will run
even if a previous middleware has already set `req.accessToken`
(possibly to `null` for anonymous requests)
- When `overwriteExistingToken` is true (and `enableDoublecheck` too),
the middleware will overwrite `req.accessToken` set by a previous
middleware instances.
- `loopback.registry` is now a true global registry
- `app.registry` is unique per app object
- `Model.registry` is set when a Model is created using any registry method
- `loopback.localRegistry` and `loopback({localRegistry: true})` when set to `true` this will create a `Registry` per `Application`. It defaults to `false`.
Enhance the error objects with a `code` property containing
a machine-readable string code describing the error, for example
INVALID_TOKEN or USER_NOT_FOUND.
Also improve 404 error messages to include the model name.
Allow convenient URLs for curl and browsers such as:
- http://some-long-token@localhost:3000/
- http://token:some-long-token@localhost:3000/
Basic Auth specifies a 'Basic' scheme for the Authorization header
similar to how OAuth specifies 'Bearer' as an auth scheme.
Following a similar convention, extract the access token from the
Authorization header when it specifies the 'Basic' scheme, assuming
it is the larger of the <user>:<pass> segments.
Make `loopback.rest` self-contained, so that authentication works
out of the box.
var app = loopback();
app.enableAuth();
app.use(loopback.rest());
Note that cookie parsing middleware is not added, users have to
explicitly configure that if they want to store access tokens
in cookies.
Modify `loopback.token` to skip token lookup when the request already
contains `accessToken` property. This is in line with other
connect-based middleware like `cookieParser` or `json`.
