MODULE 3: Creating and Consuming ASP.NET Core Web APIs

ASP.NET Core Web API provides a robust and modern framework for creating Hypertext Transfer Protocol (HTTP)-based services. In this module, you will be introduced to the HTTP-based services. You will learn how HTTP works and become familiar with HTTP messages, HTTP methods, status codes, and headers. You will also be introduced to the Representational State Transfer (REST) architectural style and hypermedia. You will learn how to create HTTP-based services by using ASP.NET Core Web API. You will also learn how to consume them from various clients. After Lesson 3, in the lab "Creating an ASP.NET Core Web APIs", you will create a web API and consume it from a client.

Lessons

After completing this module, students will be able to:

•  Design services by using the HTTP protocol.
• Create services by using ASP.NET Core Web API.
• Use the HttpRequest/IActionResult classes to control HTTP messages.
• Consume ASP.NET Web API services
• Handling HTTP Requests and Responses
• Automatically Generating HTTP Requests and Responses
• Create a controller class
• Use the API from a browser
• Create a client

 Lab : Creating an ASP.NET Core Web API

MODULE 4: Extending ASP.NET Core HTTP Services

ASP.NET Core Web API provides a complete solution for building HTTP services, but services often have various needs and dependencies. In many cases, you will need to extend or customize the way ASP.NET Core Web API executes your service. Handling needs such as applying error handling and logging integrate with other components of your application and supporting other standards that are available in the HTTP world. Understanding the way ASP.NET Core Web API works is important when you extend ASP.NET Core Web API. The division of responsibilities between components and the order of execution are important when intervening with the way ASP.NET Core Web API executes. Finally, with ASP.NET Core Web API, you can also extend the way you interact with other parts of your system. With the dependency resolver mechanism, you can control how instances of your service are created, giving you complete control on managing dependencies of the services.

Lessons

After completing this module, students will be able to:

•  Extend the ASP.NET Web API request and response pipeline
• Customize Controllers and Actions
