Как использовать аутентификацию на основе SAML в приложении IONIC

var options = { location: 'no', toolbar: 'no', clearcache: 'yes' };

var signInUrl; // Generate your signINUrl with appending detail like client id , redirection url etc. 
    
$cordovaInAppBrowser.open(signInUrl, '_blank', options)
        .then(function(event) {
          // success
        })
        .catch(function(event) {
          // error
});  // Prompt user to login 

// Interceptor to find the hash key while redirections are active.

$scope.$on('$cordovaInAppBrowser:loadstart', function (e, event) {
      var key = event.url.split('code=')[1];
      if(key) {
        console.log('got key');
        //hide spinners, 
        //logic to create user session for login.
        //Can use localstorage to store key.
        // Change state to starting page. 
        // clear any histroy/ prevent go back to login controller. 
      } else {
        console.log('loading', event.url);
        //keep on waiting. 
      }
});

$scope.$on('$cordovaInAppBrowser:loadstop', function (e, event) {
   // Handler Spinners. 
});

$scope.$on('$cordovaInAppBrowser:loaderror', function (e, event) {
   // Handler Spinners & erros. 
});
