Learn how to use resource-based authorization in ASP.NET Core

Outline the useful resource

In REST (an acronym for Representational State Switch), a useful resource is outlined as a bit of information that may be accessed utilizing a singular URI (Uniform Useful resource Identifier). Sometimes, the useful resource is described utilizing a mannequin object. On this instance, our useful resource might be an occasion of the Article class.

Within the undertaking we simply created, create a brand new file named Article.cs and write the next code in there to create our useful resource sort.

  public class Article     {         public int Id { get; set; }         public string Title { get; set; }         public string Description { get; set; }         inner readonly string Writer;     }  

Create a repository for the useful resource

In an ASP.NET Core software a repository is used to offer entry to the info retailer. On this instance, we’ll create an article repository that consists of two varieties — the IArticleRepository interface and the ArticleRepository class that implements this interface.

Create an interface named IArticleRepository in a file having the identical identify with a .cs extension and change the default generated code with the next code.

  public interface IArticleRepository     {         public Article GetArticle(int id);         public Checklist
 GetArticles();     }  

Subsequent create the ArticleRepository class. The ArticleRepository class implements the strategies of the IArticleRepository interface as proven within the code snippet given beneath.

  public class ArticleRepository : IArticleRepository     {         public Article GetArticle(int id)         {             throw new NotImplementedException();         }         public Checklist
 GetArticles()         {             throw new NotImplementedException();         }     }  

Register the repository within the Program.cs file

You need to now register the ArticleRepository class as a service utilizing the next line of code within the Program.cs file.
