Chapter 15: Request Object Deep Dive in C#

Headers, body, params, query all explained. In this chapter, you will learn request object deep dive in depth with C# code examples, explanations, and best practices.

Overview

This chapter covers request object deep dive for Kungfu.js developers using C#. We will start with the basics, move through practical examples, and end with advanced techniques and common pitfalls.

Why This Matters

Understanding request object deep dive is essential because it is a core part of building web applications. Every real-world app needs to handle headers, body, params, query all explained. Skipping this chapter would leave a gap in your knowledge that would cause problems later.

Code Example

Here is how to handle requests and responses in C#:

// Request and response handling
app.get('/example', (req) => {
    // req.method = "GET"
    // req.path = "/example"
    // req.query = { q: "search", limit: "10" }
    // req.params = { id: "42" }
    // req.headers = { host: "...", authorization: "..." }
    // req.body = ""
    
    return {
        status: 200,
        headers: { 'content-type': 'application/json' },
        body: JSON.stringify({ ok: true })
    };
});

Common Mistakes

• Not reading the documentation: Always check the API reference when something does not work as expected.
• Skipping security: Never disable the default middleware unless you have a very good reason. Security is not optional.
• Not testing: Write tests for your handlers. Kungfu.js makes this easy with the built-in test utilities.

Summary

In this chapter, you learned about request object deep dive in C#. You saw code examples, understood how things work under the hood, and learned about common mistakes to avoid.

What is Next?

In chapter 16, we will cover Response Object Deep Dive: JSON, text, HTML, raw bytes, status codes.
