This library is deprecated. Sorry guys I have no time to maintain it. Check my new project @layerr
It is an AngularJS module to manage HTTP Digest Authentication in the REST API web apps. It provides functionality to avoid the default form of browsers and use your own. The login and logout are based on digest access authentication and the module helps to manage the user identity in the client side. You can use this module in order to protect your app and authorize the user to navigate inside it.
- Using your own login and logout
- Interceptor to pass the authorization in all further requests after the login
- Protection for login with a limitation for the number of requests
- Storage for reusing credentials
- Managing identity with
authIdentityservice - Authorization checking as promise with
dgAuthService - Custom header to parse server information(realm, opaque, domain, etc...)
- Custom callbacks to handle all authorization states(login successful, login error, login required, etc...)
You can download this by:
- Using bower and running
bower install angular-digest-auth --save(recommended) - Downloading manually the unminified version or the minified production version
After installation, import the module in your app.
var app = angular.module('myApp', ['dgAuth']);This module depends by angular, angular-state-machine and angular-md5.
You have to provide a few configurations in order to work.
Create the services to sign in and sign out in order to simulate the login and
the logout in your app. signin service should return the JSON of the user identity.
You can use the user identity with authIdentity service.
app.config(['dgAuthServiceProvider', function(dgAuthServiceProvider)
{
dgAuthServiceProvider.setConfig({
login: {
method: 'POST',
url: '/signin'
...
//Other HTTP configurations.
},
logout: {
method: 'POST',
url: '/signout'
...
//Other HTTP configurations.
}
});
}]);How to configure the header to parse server information. You should define a custom header in the server side in order to avoid the browser form and use your custom login form.
app.config(['dgAuthServiceProvider', function(dgAuthServiceProvider)
{
/**
* Specifies the header to look for server information.
* The header you have used in the server side.
*/
dgAuthServiceProvider.setHeader('Your-Header-For-Authentication');
}]);How to configure the limit of number requests to sign in. When the limit is exceeded
limit of login callbacks is invoked. The default limit is 4.
N.B.: the limit includes the request to sign in place during the invocation of the start method.
app.config(['dgAuthServiceProvider', function(dgAuthServiceProvider)
{
/**
* Sets the limit to 5 requests.
* 4 requests after the invocation of start method.
*/
dgAuthServiceProvider.setLimit(5);
/**
* Sets the limit of requests to infinite.
*/
dgAuthServiceProvider.setLimit('inf');
}]);How to configure what happens at the user login and/or logout.
app.config(['dgAuthServiceProvider', function(dgAuthServiceProvider)
{
/**
* You can add the callbacks to manage what happens after
* successful of the login.
*/
dgAuthServiceProvider.callbacks.login.push(['serviceInject', function(serviceInject)
{
return {
successful: function(response)
{
//Your code...
},
error: function(response)
{
//Your code...
},
required: function(response)
{
//Your code...
},
limit: function(response)
{
//Your code...
}
};
}]);
//This is the same for the logout.
/**
* You can add the callbacks to manage what happens after
* successful of the logout.
*/
dgAuthServiceProvider.callbacks.logout.push(['serviceInject', function(serviceInject)
{
return {
successful: function(response)
{
//Your code...
},
error: function(response)
{
//Your code...
}
};
}]);
}]);By default, after the user has made the login, the credentials are stored in sessionStorage and the module
processes all further requests with this credentials. If you want to restore the user credentials when
he returns in your app, you can specify the localStorage as default storage.
app.config(['dgAuthServiceProvider', function(dgAuthServiceProvider)
{
/**
* Uses localStorage instead the sessionStorage.
*/
dgAuthServiceProvider.setStorage(localStorage);
}]);Obviously, if you want to specify your own storage object, you can :).
For basic usage, you can launch the start() when your app goes run.
app.run(['dgAuthService', function(dgAuthService)
{
/**
* It tries to sign in. If the service doesn't find
* the credentials stored or the user is not signed in yet,
* the service executes the required function.
*/
dgAuthService.start();
}]);In your login controller you should provide the credentials submitted by user. Then you have to sign in another time.
$scope.submit = function(user)
{
dgAuthService.setCredentials(user.username, user.password);
dgAuthService.signin();
};If the login is successful, all further requests, for the API in the domain specified by the server header, contains the authentication to authorize the user.
You can use a functionality of dgAuthService to authorize the user to navigate in your app.
app.config(['$routeProvider', function($routeProvider)
{
/**
* Use a variable in resolve to authorize the users.
* The method 'isAuthorized()' returns a promise
* which you can use to authorize the requests.
*/
$routeProvider.when('some/path', {
...
resolve: {
auth: ['dgAuthService', '$q', '$location', function(dgAuthService, $q, $location)
{
var deferred = $q.defer();
dgAuthService.isAuthorized().then(function(authorized)
{
if(authorized)
deferred.resolve();
else
deferred.reject();
},
function(authorized)
{
deferred.reject();
});
return deferred.promise;
}]
}
});
}]);
