Part 2: Share Authentication Cookie - Application Runs Under Another Application

Introduction:
In Part-1 we have implemented SSO with sharing authentication cookie between domain and subdomain binds to an MVC application. Now we implement the sharing authentication cookie between two different applications which runs under another application in IIS Server. For example, ASP.NET Core MVC application is client application shares login cookie to the ASP.NET Core WEB API which is hosted under the MVC application as a child in IIS Server. To know more about child application runs under another application click here

Core Concept:
Sharing authentication Cookie between entirely two different applications, but one application runs under other applications in IIS.

Create an MVC Application:
Create an MVC application by following Part-1, consider it is the main application for registering users and log-in to the application.

Create WEB API Application:
Now we have to create another application, which runs under the MVC application(created by following Step 1) this application will be the child application. we are going to use the login cookie created in MVC's main application, in the child application to make the user as authenticated.

Create Asp.net Core Web API application, while creating a project from VisualStudio select authentication to none in the web API template.

Application Hosting And Domain Bindings:
Now host the Web API application under the MVC application as a child in IIS. To host an application under another application click here.

After hosting your application should looks as below.

So here "TestCookieShareMvc" is our main MVC application which can be accessed with URL "http://testmyapp.com". "API" is our Dotnet core web API application is a child application that can be accessed with URL "http://testmypp.com/api".

Run ASP.NET Core WEB API Application:
In the Dotnet Core Web API project, we have a predefined endpoint to test API, so navigate to that endpoint as "http://testmyapp.com/api/values" and it results as below

Error On Adding Authorize Attribute:
Now add "Authorization" attribute to the endpoint as below

Now once again navigate to same endpoint "http://testmyapp.com/api/values", its results in an error
as saying no authentication scheme adds as below

Configure Authentication Middleware:
Now we need to add an authentication scheme to our web API. In the dotnet core, we can add authentication as middleware. Open "Startup.cs" file in the "configure" method need to add authentication middleware as below

Register ASP.NET Core Identity Authentication:
In Startup.cs file now register authentication in "ConfigureService()" as below

. "Coookie.Name" should be the same as the name used in MVC application
. "Identity.Application" it is an authentication schema name, by default Microsoft Identity login uses this schema name. If you are using IdentityServer4 Login then the schema name will be different. So it depends on your login plugin.

"Note: Here in this sample for login I have used Microsoft Identity in MVC application. So schema name should be 'Identity.Application'. If you used any self-made name it won't work"

401 UnAuthorized:
Now navigate to "http://testmyapp.com/api/values" you will get unauthorized 401 status as below

Data Protection API Service Registration:
The final step is to register the Data Protection API the same as we did in the MVC application.

Pass directory info also same as we did in MVC application that looks as follows

In appSetting.json file pass the Path of MVC application "Ring" folder path in this Web API project as below

Run Application To Test Authentication:
Now navigate to "http://testmyapp.com" then log in with your user credentials. After successfully login now navigate to Web API application as "http://testmyapp.com/api/values" you will able to see endpoint gets authorized and JSON result from the API.

Summary:
Here we have shared a login cookie between the client application (MVC) and the API Application (WEB API) as a child to the MVC. Data Protection API which is provided by ASP.NET Core used for encryption and decryption helped in creating the secured login cookie.

Angular 14 Reactive Forms Example

In this article, we will explore the Angular(14) reactive forms with an example. Reactive Forms: Angular reactive forms support model-driven techniques to handle the form's input values. The reactive forms state is immutable, any form filed change creates a new state for the form. Reactive forms are built around observable streams, where form inputs and values are provided as streams of input values, which can be accessed synchronously. Some key notations that involve in reactive forms are like: FormControl - each input element in the form is 'FormControl'. The 'FormControl' tracks the value and validation status of form fields. FormGroup - Track the value and validate the state of the group of 'FormControl'. FormBuilder - Angular service which can be used to create the 'FormGroup' or FormControl instance quickly. Form Array - That can hold infinite form control, this helps to create dynamic forms. Create An Angular(14) Application: Let'

.NET 7 Web API CRUD Using Entity Framework Core

In this article, we are going to implement a sample .NET 7 Web API CRUD using the Entity Framework Core. Web API: Web API is a framework for building HTTP services that can be accessed from any client like browser, mobile devices, and desktop apps. In simple terminology API(Application Programming Interface) means an interface module that contains programming functions that can be requested via HTTP calls either to fetch or update data for their respective clients. Some of the Key Characteristics of API: Supports HTTP verbs like 'GET', 'POST', 'PUT', 'DELETE', etc. Supports default responses like 'XML' and 'JSON'. Also can define custom responses. Supports self-hosting or individual hosting, so that all different kinds of apps can consume it. Authentication and Authorization are easy to implement. The ideal platform to build the REST full services. Install The SQL Server And SQL Management Studio: Let's install the SQL server on our l

ReactJS(v18) JWT Authentication Using HTTP Only Cookie

In this article, we will implement the ReactJS application authentication using the HTTP-only cookie. HTTP Only Cookie: In a SPA(Single Page Application) Authentication JWT token either can be stored in browser 'LocalStorage' or in 'Cookie'. Storing the JWT token inside of the cookie then the cookie should be HTTP Only. The HTTP-ONly cookie nature is that it will be only accessible by the server application. Client apps like javascript-based apps can't access the HTTP-Only cookie. So if we use the authentication with HTTP-only JWT cookie then we no need to implement the custom logic like adding authorization header or storing token data, etc at our client application. Because once the user authenticated cookie will be automatically sent to the server by the browser on every API call. Authentication API: To authenticate our client application with JWT HTTP-only cookie, I developed a NetJS(which is a node) Mock API. Check the GitHub link and read the document on G

Angular 14 State Management CRUD Example With NgRx(14)

In this article, we are going to implement the Angular(14) state management CRUD example with NgRx(14) NgRx Store For State Management: In an angular application to share consistent data between multiple components, we use NgRx state management. Using NgRx state helps to avoid unwanted API calls, easy to maintain consistent data, etc. The main building blocks for the NgRx store are: Actions - NgRx actions represents event to trigger the reducers to save the data into the stores. Reducer - Reducer's pure function, which is used to create a new state on data change. Store - The store is the model or entity that holds the data. Selector - Selector to fetch the slices of data from the store to angular components. Effects - Effects deals with external network calls like API. The effect gets executed based the action performed Ngrx State Management flow: The angular component needs data for binding. So angular component calls an action that is responsible for invoking the API call. Aft

Unit Testing Asp.NetCore Web API Using xUnit[.NET6]

In this article, we are going to write test cases to an Asp.NetCore Web API(.NET6) application using the xUnit. xUnit For .NET: The xUnit for .Net is a free, open-source, community-focused unit testing tool for .NET applications. By default .Net also provides a xUnit project template to implement test cases. Unit test cases build upon the 'AAA' formula that means 'Arrange', 'Act' and 'Assert' Arrange - Declaring variables, objects, instantiating mocks, etc. Act - Calling or invoking the method that needs to be tested. Assert - The assert ensures that code behaves as expected means yielding expected output. Create An API And Unit Test Projects: Let's create a .Net6 Web API and xUnit sample applications to accomplish our demo. We can use either Visual Studio 2022 or Visual Studio Code(using .NET CLI commands) to create any.Net6 application. For this demo, I'm using the 'Visual Studio Code'(using the .NET CLI command) editor. Create a fo

Part-1 Angular JWT Authentication Using HTTP Only Cookie[Angular V13]

In this article, we are going to implement a sample angular application authentication using HTTP only cookie that contains a JWT token. HTTP Only JWT Cookie: In a SPA(Single Page Application) Authentication JWT token either can be stored in browser 'LocalStorage' or in 'Cookie'. Storing JWT token inside of the cookie then the cookie should be HTTP Only. The HTTP-Only cookie nature is that it will be only accessible by the server application.

So if we use authentication with HTTP only JWT cookie then we no need to implement custom logic like adding authorization header or storing token data, etc at our client application. Because once the user authenticated cookie will be automatically sent to the server by the browser on every API call. Authentication API: To implement JWT cookie authentication we need to set up an API. For that, I had created a mock authentication API(Using the NestJS Se

Angular 14 Crud Example

In this article, we will implement CRUD operation in the Angular 14 application. Angular: Angular is a framework that can be used to build a single-page application. Angular applications are built with components that make our code simple and clean. Angular components compose of 3 files like TypeScript File(*.ts), Html File(*.html), CSS File(*.cs) Components typescript file and HTML file support 2-way binding which means data flow is bi-directional Component typescript file listens for all HTML events from the HTML file. Create Angular(14) Application: Let's create an Angular(14) application to begin our sample. Make sure to install the Angular CLI tool into our local machine because it provides easy CLI commands to play with the angular application.

ReactJS(v18) Authentication With JWT AccessToken And Refresh Token

In this article, we are going to do ReactJS(v18) application authentication using the JWT Access Token and Refresh Token. JSON Web Token(JWT): JSON Web Token is a digitally signed and secured token for user validation. The JWT is constructed with 3 important parts: Header Payload Signature Create ReactJS Application: Let's create a ReactJS application to accomplish our demo. npx create-react-app name-of-your-app Configure React Bootstrap Library: Let's install the React Bootstrap library npm install react-bootstrap bootstrap Now add the bootstrap CSS reference in 'index.js'. src/index.js: import 'bootstrap/dist/css/bootstrap.min.css' Create A React Component 'Layout': Let's add a React component like 'Layout' in 'components/shared' folders(new folders). src/components/shared/Layout.js: import Navbar from "react-bootstrap/Navbar"; import { Container } from "react-bootstrap"; import Nav from "react-boot

A Small Guide On NestJS Queues

NestJS Application Queues helps to deal with application scaling and performance challenges. When To Use Queues?: API request that mostly involves in time taking operations like CPU bound operation, doing them synchronously which will result in thread blocking. So to avoid these issues, it is an appropriate way to make the CPU-bound operation separate background job. In nestjs one of the best solutions for these kinds of tasks is to implement the Queues. For queueing mechanism in the nestjs application most recommended library is '@nestjs/bull'(Bull is nodejs queue library). The 'Bull' depends on Redis cache for data storage like a job. So in this queueing technique, we will create services like 'Producer' and 'Consumer'. The 'Producer' is used to push our jobs into the Redis stores. The consumer will read those jobs(eg: CPU Bound Operations) and process them. So by using this queues technique user requests processed very fastly because actually
