HTTP Interceptors in Angular JS

Http Interceptors are similar to .NET http modules. It will interfere before sending request to the server and after receiving the response from the server.

The $http service is a core Angular service that facilitates communication with remote server to make http request. In certain scenarios,

i. We have to capture every http request and manipulate it before sending it to the remote server.
ii. We have to capture the http response from the server and manipulate it before sending it to the client

So in our example, we are using Http Interceptor to attach authentication token to the http request before sending to the server for validating the logged in user.

Check “app.config.js” file to verify how we have configured Http Interceptors in Angular JS
