Hands-On RESTful Web Services with ASP.NET Core 3

By: Samuele Resca

Overview of this book

In recent times, web services have evolved to play a prominent role in web development. Applications are now designed to be compatible with any device and platform, and web services help us keep their logic and UI separate. Given its simplicity and effectiveness in creating web services, the RESTful approach has gained popularity, and this book will help you build RESTful web services using ASP.NET Core. This REST book begins by introducing you to the basics of the REST philosophy, where you'll study the different stages of designing and implementing enterprise-grade RESTful web services. You'll also gain a thorough understanding of ASP.NET Core's middleware approach and learn how to customize it. The book will later guide you through improving API resilience, securing your service, and applying different design patterns and techniques to achieve a scalable web service. In addition to this, you'll learn advanced techniques for caching, monitoring, and logging, along with implementing unit and integration testing strategies. In later chapters, you will deploy your REST web services on Azure and document APIs using Swagger and external tools such as Postman. By the end of this book, you will have learned how to design RESTful web services confidently using ASP.NET Core with a focus on code testability and maintainability.

Data transfer objects

In the previous section, we looked at how to manage HTTP requests and responses using controllers. In this section, we will look at how to manage complex objects in our requests and responses. This section is more focused on the M part of the MVC pattern. First of all, let's distinguish between three different types of model that are usually present in web services:

  • The Domain model describes the entities and the resources in our web services. It often reflects the schema of our data source, and it is very close to the lower level and the business logic of the application.
  • The Request model is the representation of the model of the request. Each action method in our controller usually has its own Request model. As we will see later in this chapter, this is also the model that's associated with the validation of the request.
  • The Response model is...
