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

      
      class ResponseOptions {
  constructor(opts: ResponseOptionsArgs = {})
  body: string | Object | ArrayBuffer | Blob | null
  status: number | null
  headers: Headers | null
  url: string | null
  merge(options?: ResponseOptionsArgs): ResponseOptions
}

Subclasses

BaseResponseOptions

Description

This class is based on the ResponseInit description in the Fetch Spec.

All values are null by default. Typical defaults can be found in the BaseResponseOptions class, which sub-classes ResponseOptions.

This class may be used in tests to build Responses for mock responses (see MockBackend).

Constructor

      
      constructor(opts: ResponseOptionsArgs = {})

Parameters

opts

ResponseOptionsArgs

Optional. Default is {}.

Properties

Property	Description
`body: string \| Object \| ArrayBuffer \| Blob \| null`	String, Object, ArrayBuffer or Blob representing the body of the `Response`.
`status: number \| null`	Http status code associated with the response.
`headers: Headers \| null`	Response headers
`url: string \| null`

Methods

merge()

Creates a copy of the ResponseOptions instance, using the optional input as values to override existing values. This method will not change the values of the instance on which it is being called.

      
      merge(options?: ResponseOptionsArgs): ResponseOptions

Parameters

options

ResponseOptionsArgs

Optional. Default is undefined.

Returns

ResponseOptions

This may be useful when sharing a base ResponseOptions object inside tests, where certain properties may change from test to test.

  url: 'https://google.com'
