Creating a Web API with ASP.NET Core and .NET 6

🌐 A web API is a set of functions used to access different functionalities from third-party software, and it uses the HTTP protocol.

📚 There are different types of web APIs, including REST API, RPC, and GraphQL, each with their own strengths and weaknesses.

💻 A web API can be used to integrate payments, create backends for mobile or single page applications, or exchange data between systems.

🔧 To create a web API, you can use ASP.NET Core and .NET 6, and it involves exposing different endpoints for performing CRUD operations on resources.

📝 Returning a list of issues as the response

📌 To handle a GET request for a specific issue ID, use the 'get_by_id' method decorated with the 'HttpGet' attribute.

✅ If the issue ID is found, return an OK response with a 200 status code; otherwise, return a NotFound response with a 404 status code.

➕ To create a new issue, use the 'create' method decorated with the 'HttpPost' attribute and add the submitted issue to the database.

📝 To update an issue in the web API, we add an action method with an HTTP PUT attribute and bind the ID to the URL and the issue to the request body.

✅ The method checks if there is a mismatch between the ID in the URL and the ID in the body and returns a bad request if there is no match. Otherwise, it updates the issue and returns a 204 status code.

🗑️ To delete an issue, we add a method with an HTTP DELETE attribute and check if the issue exists. If it does, we delete the issue and return a 204 status code.
