Creates Response instances from provided values.

弃用说明

see https://angular.io/guide/http

class Response extends Body { constructor(responseOptions: ResponseOptions) type: ResponseType ok: boolean url: string status: number statusText: string | null bytesLoaded: number totalBytes: number headers: Headers | null toString(): string }

说明

Though this object isn't usually instantiated by end-users, it is the primary object interacted with when it comes time to add data to a view.

Example

http.request('my-friends.txt').subscribe(response => this.friends = response.text());

The Response's interface is inspired by the Response constructor defined in the Fetch Spec, but is considered a static value whose body can be accessed many times. There are other differences in the implementation, but this is the most significant.
