class

npm Package	@angular/http
Module	import { ResponseOptions } from '@angular/http';
Source	http/src/base_response_options.ts

Overview

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

Description

Creates a response options object to be optionally provided when instantiating a Response.

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).

Example (live demo)

import {ResponseOptions, Response} from '@angular/http';

var options = new ResponseOptions({
  body: '{"name":"Jeff"}'
});
var res = new Response(options);

console.log('res.json():', res.json()); // Object {name: "Jeff"}

Subclasses

• BaseResponseOptions

Constructor

Members

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

merge(options?: ResponseOptionsArgs): ResponseOptions

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.

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

Example (live demo)

import {ResponseOptions, Response} from '@angular/http';

var options = new ResponseOptions({
  body: {name: 'Jeff'}
});
var res = new Response(options.merge({
  url: 'https://google.com'
}));
console.log('options.url:', options.url); // null
console.log('res.json():', res.json()); // Object {name: "Jeff"}
console.log('res.url:', res.url); // https://google.com
