TestRequest

class

A mock requests that was received and is ready to be answered.

      
      class TestRequest {
  constructor(request: HttpRequest<any>, observer: Observer<HttpEvent<any>>)
  cancelled: boolean
  request: HttpRequest<any>
  flush(body: string | number | Object | ArrayBuffer | Blob | (string | number | Object)[], opts: { headers?: HttpHeaders | { [name: string]: string | string[]; }; status?: number; statusText?: string; } = {}): void
  error(error: ErrorEvent, opts: { headers?: HttpHeaders | { [name: string]: string | string[]; }; status?: number; statusText?: string; } = {}): void
  event(event: HttpEvent<any>): void
}

Description

This interface allows access to the underlying HttpRequest, and allows responding with HttpEvents or HttpErrorResponses.

Constructor

      
      constructor(request: HttpRequest<any>, observer: Observer<HttpEvent<any>>)

Parameters

`request`	`HttpRequest`
`observer`	`Observer>`

Properties

Property	Description
`cancelled: boolean`	Read-only. Whether the request was cancelled after it was sent.
`request: HttpRequest<any>`	Declared in constructor.

Methods

flush()

Resolve the request by returning a body plus additional HTTP information (such as response headers) if provided. If the request specifies an expected body type, the body is converted into the requested type. Otherwise, the body is converted to JSON by default.

      
      flush(body: string | number | Object | ArrayBuffer | Blob | (string | number | Object)[], opts: { headers?: HttpHeaders | { [name: string]: string | string[]; }; status?: number; statusText?: string; } = {}): void

Parameters

`body`	`string \| number \| Object \| ArrayBuffer \| Blob \| (string \| number \| Object)[]`
`opts`	`object`	Optional. Default is `{}`.

Returns

void

Both successful and unsuccessful responses can be delivered via flush().

error()

Resolve the request by returning an ErrorEvent (e.g. simulating a network failure).

      
      error(error: ErrorEvent, opts: { headers?: HttpHeaders | { [name: string]: string | string[]; }; status?: number; statusText?: string; } = {}): void

Parameters

`error`	`ErrorEvent`
`opts`	`object`	Optional. Default is `{}`.

Returns

void

event()

Deliver an arbitrary HttpEvent (such as a progress event) on the response stream for this request.

      
      event(event: HttpEvent<any>): void

Parameters

event HttpEvent

Returns

void
