Login HTTP Authentication in AngularJs

The authentication and authorization are the most important part of every application but different type to process to used to Authentication and authorization.

Today's I am going to share the code sample of HTTP Authentication (single page application) using AngularJs.

The two types of Authentication

  1. The cookies based authentication and Its done by server side cookies for each user request. 
  2. The token based authentication and it's done by send the token for each request.
I am using to server side token based authentication and the below steps and display images show the how to write the code sample. 

The Table of Context 
  1. Configure the Routes for Application. 
  2. Write the controller code. 
  3. Login controller. 
  4. Landing controller. 
  5. Write the Factory code. 
  6. Login factory. 
  7. Authentication Http Response Interceptor. 
  8. HTML Code for Login Page. 
  9. HTML code for Index page. 
  10. Bundling of Js files.

 Configure the Application setting
