- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the
future.
BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.
foo.setUpMock();
}
```
PR Close#13785
Fix(http): invalidStateError if response body without content
If the responseType has been specified and other than 'text', responseText throw an InvalidStateError exception
See XHR doc => https://xhr.spec.whatwg.org/#the-responsetext-attribute
Unit Test to prevent invalidStateError
When creating a new Headers object using an existing Headers object
the existing Headers map is copied by reference. Therefore adding a
new Header value to the new Headers object also added this value to
the existing Headers object which is not in accordance with the
spec.
This commit alters the constructor to create a deep copy of existing
Headers maps and therefore unlink existing Headers from new Headers.
Closes#6845
BREAKING CHANGE:
any code which relies on the fact that a newly
created Headers object is referencing an existing Headers map is
now broken, but that should normally not be the case since this
behavior is not documented and not in accordance with the spec.
