Understanding Query String Routing in ASP.NET Core API Projects

When building ASP.NET Core API projects, developers often come across situations where they want to clean up their URL routing. A common query is whether it's possible to route a query string parameter to a controller action without specifying a query string name. This is particularly relevant if you want your endpoint to look cleaner and more user-friendly.

For example, you might want to use a URL formatted like this:

instead of a more verbose format like:

In this guide, we will explore how to achieve that within an ASP.NET Core application.

The Problem

The existing code you might have is struggling with the implementation of routing a parameter from the query string without a specified name. Here’s an example of the code that might be frustrating developers:

This method is expecting a named query string parameter (bitcode), which is not present in the URL you want to use.

While trying to achieve custom routing, it may have fallen short. Let’s uncover the solution.

The Solution

Leveraging the HttpRequest Object

To handle this scenario, you can utilize the HttpRequest object, which is available to all controllers. This allows you to access the query strings processed in the context of the request without needing to specify the name. Here’s how you can do it:

Modify Your Action Method: Change the method to no longer accept a parameter directly.

Benefits of This Approach

Cleaner URLs: You can craft more user-friendly URLs by omitting unnecessary query parameter names.

Flexibility: It gives you more flexibility in how you handle different kinds of data without making assumptions about parameter names.

Simple Implementation: Use of HttpRequest streamlines the code and simplifies how data is extracted from the request.

Conclusion

Routing query string parameters without a query string name in ASP.NET Core can improve the usability of your APIs while keeping the implementation straightforward. By leveraging the built-in HttpRequest object, you can design URLs that are both clean and functional, enhancing user experience without complicating your codebase.
