Angular2: How to Get the user name of the logged in user

Question

Hi Anguar 2 experts,

 

I have a question, 

 

In Angular 2, How can we get the user name of the logged in user.

 

I log in to the windows computer with the network credentials. So how can i get the user name in angular application. If we can directly get user name in angular2. what is the application solution to implement using angular2.

 

Thanks,

Kiran
