Here's a code dump of the parts of the Dispatcher prototype codebase
that are needed to get us off the ground.
This first cut attempts to use part of routing where possible, and not
all of those changes will be long-lasting.
I'll leave comments through thoughout the PR for education.
Adds IRouterHandler, an abstraction for endpoints in the routing system
that can't chain (example: delegates). The idea is that some kinds of
routes aren't really friendly to chaining. If you don't support chaining,
then accept IRouteHandler and work with that rather than IRouter.
There's one implementation of IRouteHandler, RouteHandler. It implements
both IRouter and IRouteHandler.
Adds RouteBase as a base class for routes based on our template syntax and
defaults/constraints/data-tokens. Updated a lot of signatures to be
get/set virtual and mutable to facilitate or bigger variety of usage
scenarios.
Renamed TemplateRoute to just Route, now inherits from RouteBase.
Adds IRoutingFeature for middleware scenarios where you don't have access
to the route context.
Also adds some basic extension methods for accessing route values.
This is a sample of the pattern for building a MapRoute method that
customizes routing by adding constraints, datatokens, or defaults. This is
the replacement for adding data to the route directly.
Also fixed up the sample to work. It was massively out of date.
This is the routing part of these changes, and just the breaking changes
parts.
Follow-ups will add:
- DataTokens
- Tracking the logical stack of routers
Moving out Default Handler and IInlineConstraintResolver from RouteCollection.
These are moved to a new interface IRouteBuilder, (instead of an IInlineConstraintResolver, it takes in an IServiceProvider).
This means all RouteCollectionExtensions are moved to RouteBuilderExtensions.
