JarCastingangular-oauth2 
AngularJS OAuth2 authentication module written in ES6.
Currently angular-oauth2 only uses the Resouce Owner Password Credential Grant, i.e, using a credentials combination (username, password), we'll request an access token (using grant_type='password') which, in case of success, will typically return a response such as:
{
"access_token": "foobar",
"token_type": "Bearer",
"expires_in": 3600,
"refresh_token": "foobiz"
}
Internally we'll automatically store it as a cookie and it will be used in every request adding an Authorization header: Authorization: 'Bearer foobar'.
Installation
Choose your preferred method:
- Bower:
bower install angular-oauth2 - NPM:
npm install --save angular-oauth2 - Download: angular-oauth2
Usage
1. Download angular-oauth2 dependencies.
If you're using bower they will be automatically downloaded upon installing this library.
2. Include angular-oauth2 and dependencies.
<script src="<VENDOR_FOLDER>/angular/angular.min.js"></script>
<script src="<VENDOR_FOLDER>/angular-cookies/angular-cookies.min.js"></script>
<script src="<VENDOR_FOLDER>/query-string/query-string.js"></script>
<script src="<VENDOR_FOLDER>/angular-oauth2/dist/angular-oauth2.min.js"></script>
3. Configure OAuth (optional) and OAuthToken (optional):
angular.module('myApp', ['angular-oauth2'])
.config(['OAuthProvider', function(OAuthProvider) {
OAuthProvider.configure({
baseUrl: 'https://api.website.com',
clientId: 'CLIENT_ID',
clientSecret: 'CLIENT_SECRET' // optional
});
}]);
You can also configure OAuth service in a .run() block, in case you retrieve the Oauth server configuration from a ajax request.
angular.module('myApp', ['angular-oauth2'])
.run(['OAuth', function(OAuth) {
OAuth.configure({
baseUrl: 'https://api.website.com',
clientId: 'CLIENT_ID',
clientSecret: 'CLIENT_SECRET' // optional
});
}]);
4. Catch OAuth errors and do something with them (optional):
angular.module('myApp', ['angular-oauth2'])
.run(['$rootScope', '$window', 'OAuth', function($rootScope, $window, OAuth) {
$rootScope.$on('oauth:error', function(event, rejection) {
// Ignore `invalid_grant` error - should be catched on `LoginController`.
if ('invalid_grant' === rejection.data.error) {
return;
}
// Refresh token when a `invalid_token` error occurs.
if ('invalid_token' === rejection.data.error) {
return OAuth.getRefreshToken();
}
// Redirect to `/login` with the `error_reason`.
return $window.location.href = '/login?error_reason=' + rejection.data.error;
});
}]);
API
OAuthProvider
Configuration defaults:
OAuthProvider.configure({
baseUrl: null,
clientId: null,
clientSecret: null,
grantPath: '/oauth2/token',
revokePath: '/oauth2/revoke'
});
OAuth
Update configuration defaults:
OAuth.configure({
baseUrl: null,
clientId: null,
clientSecret: null,
grantPath: '/oauth2/token',
revokePath: '/oauth2/revoke'
});
Check authentication status:
/**
* Verifies if the `user` is authenticated or not based on the `token`
* cookie.
*
* @return {boolean}
*/
OAuth.isAuthenticated();
Get an access token:
/**
* Retrieves the `access_token` and stores the `response.data` on cookies
* using the `OAuthToken`.
*
* @param {object} user - Object with `username` and `password` properties.
* @param {object} config - Optional configuration object sent to `POST`.
* @return {promise} A response promise.
*/
OAuth.getAccessToken(user, options);
Refresh access token:
/**
* Retrieves the `refresh_token` and stores the `response.data` on cookies
* using the `OAuthToken`.
*
* @return {promise} A response promise.
*/
OAuth.getRefreshToken()
Revoke access token:
/**
* Revokes the `token` and removes the stored `token` from cookies
* using the `OAuthToken`.
*
* @return {promise} A response promise.
*/
OAuth.revokeToken()
NOTE: An event oauth:error will be sent everytime a responseError is emitted:
{ status: 400, data: { error: 'invalid_request' }{ status: 400, data: { error: 'invalid_grant' }{ status: 401, data: { error: 'invalid_token' }{ status: 401, headers: { 'www-authenticate': 'Bearer realm="example"' } }
OAuthTokenProvider
OAuthTokenProvider uses angular-cookies to store the cookies. Check the available options.
Configuration defaults:
OAuthTokenProvider.configure({
name: 'token',
options: {
secure: true
}
});
OAuthToken
If you want to manage the token yourself you can use OAuthToken service. Please check the OAuthToken source code to see all the available methods.
