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.

Implementing the logging part

In this section, we will learn how to perform logging in the catalog web service. Let's start by choosing a layer where we'll execute the logging statements. Since the logic is encapsulated in the Catalog.Domain layer project, we will continue by implementing the logging part on the service classes defined in the project. First of all, let's start by defining a new logging class, which contains the corresponding event id for each operation:

namespace Catalog.Domain.Logging
{
public class Events
{
public const int Get = 1000;
public const int GetById = 1001;
public const int Add = 1002;
public const int Edit = 1003;
public const int Delete = 1004;
}
}

Once we have established a corresponding log event id for each activity, we need to define the logging messages that will be used by the ILogger...
