Modern Web Development with ASP.NET Core 3 - Second Edition

By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

Deploying with NGINX

NGINX is a very popular reverse-proxy server for the Unix and Linux family of operating systems. Like IIS, it offers interesting features that are not provided out of the box by the ASP.NET Core hosts, such as caching requests, serving files straight from the filesystem, SSL termination, and others. You can configure it to forward requests to an ASP.NET Core application that is running standalone. This application needs to be modified to acknowledge forwarded headers as in the following:

app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders =
ForwardedHeaders.XForwardedFor |
ForwardedHeaders.XForwardedProto |
ForwardedHeaders.XForwardedHost
});

What this code does is extract information from the headers, X-Forwarded-For (requesting the client IP and possibly the port), X-Forwarded-Proto (the requesting protocol), and X-Forwarded-Host (the requesting host), and sets it in the appropriate properties...
