Angular Components - AuthHttpClient

Requirements:

• '@dvs-angular/storage' and its Storage provided

Usage

Start

• in app.module import { AuthHttpClientModule } from '@dvs-angular/auth-http-client';

• add it into app imports

Set token

• if you get your token (e.g. after login) use TokenService to store it

`import { TokenService, Token } from '@dvs-angular/auth-http-client';`

...

tokenService.setToken(new Token('yourToken'))

How to use

AuthHttpClient extends HttpClient so you can use it as regular HttpClient

• AuthHttpClient offers you subscription to denied responses only inject AuthHttpClient and subscribe to onAccessDenied subject

Refresh token

AuthHttpClient supports refresh token, to use it, you have to provide REFRESH_TOKEN_API_URL

e.g.

import { REFRESH_TOKEN_API_URL } from '@dvs-angular/auth-http-client';

...

    {
      provide: REFRESH_TOKEN_API_URL,
      useValue: environment.apiUrl + 'token/refresh'
    }

and when you set Token you must pass second argument with refreshToken

    new Token('yourToken', 'yourRefreshToken')

Config

You can override some values by providing them in your module

• TOKEN_STORAGE_NAME (default: 'token')

• REFRESH_TOKEN_STORAGE_NAME (default: 'refreshToken')

e.g.

import { TOKEN_STORAGE_NAME } from '@dvs-angular/auth-http-client';

...

    {
      provide: TOKEN_STORAGE_NAME,
      useValue: 'myTokenStorageSuperName'
    }

API requirements

• method: POST

• body:

{
    refresh_token: 'yourRefreshToken'
}

• response:

{
    token: 'newToken',
    refresh_token: 'refreshToken'
}

When everything is set, AuthHttpClient after 401 response tries to refresh token and repeat request, so you have to do... nothing :)

Public Methods

TokenService

• setToken(token: Token): void;

sets and stores tokens, remember to use Token model

• getTokenString(): string;

returns raw stored token

• canRefreshToken(): boolean;

tells if refreshing is possible

• clearToken(): void;

unsets and removes from storage tokens

• getPrefixedToken(): string;

returns token as it's passed in header

• getTokenHeaderName(): string;

returns name of header which passes the token

• setRefreshTokenApiUrl(url: string): void;

allows you to set token api url config later than in provide

e.g. from async config

it's recommended to set this in APP_INITIALIZER factory

• refresh(): Observable<Token>;

refreshes token
