In ASP.NET Core, there are multiple ways to handle API versioning. Here are three commonly used approaches:
- URL-based Versioning: With this approach, the version number is included in the URL of the API endpoint. For example:
You can achieve URL-based versioning by configuring the routing system in ASP.NET Core to include the version in the route template. This can be done using the
MapControllerRoute methods in the
- Query Parameter-based Versioning: In this approach, the version number is specified as a query parameter in the API URL. For example:
To implement query parameter-based versioning, you can use the
ApiVersion attribute on your controllers or actions and configure the routing system to include the version as a query parameter.
- Header-based Versioning: This approach involves specifying the version number in a custom header of the HTTP request. For example:
GET /products HTTP/1.1 Host: api.example.com X-API-Version: 1
To implement header-based versioning, you can create a custom versioning policy and apply it to your controllers or actions using attributes like
It's important to note that these are just a few approaches to API versioning in ASP.NET Core, and there are other techniques available as well. The choice of versioning strategy depends on your specific requirements and preferences.
