CLIENT_ID​

▪ Static Private CLIENT_ID: string = "auvious"

Accessors​

_defaultHandlers​

• Protected get _defaultHandlers(): OAuth2ClientHandlers

Returns​

OAuth2ClientHandlers

Overrides​

EventFiringClient._defaultHandlers

clientId​

• get clientId(): string

Gets the oauth2 client id.

Returns​

string

clientSecret​

• get clientSecret(): string

Gets the oauth2 client secret.

Returns​

string

isAuthenticated​

• get isAuthenticated(): boolean

Checks if the token instance exists.

When an authenticated client gets an authentication error (due to expiration) it should issue a refresh_token grant.

However, non authenticated client should issue a password grant to login.

Returns​

boolean

postman​

• Private get postman(): Postman

Returns​

Postman

token​

• get token(): IOAuth2Token

Gets the current token of the authenticated user. Can be undefined.

Returns​

IOAuth2Token

Methods​

_cleanEventHandlers​

▸ Protected _cleanEventHandlers(): void

Clean event handler callbacks.

We actually just reassign to the default callbacks.

Returns​

void

Inherited from​

EventFiringClient._cleanEventHandlers

_setEventHandlers​

▸ Protected _setEventHandlers(handlers): void

Sets event handler callbacks.

Every event handler callback defaults to _defaultHandlers which just prints the event to console.

An event callback that was not passed in the argument, will default to either:

  • the previous callback is ever set.
  • the _defaultHandlers's corresponding callback.

The default behaviour when appendToPrevious = true is to append the handlers passed in the arguments.

If appendToPrevious is set to false the previous handlers will be cleaned before we the the argument handlers.
