Learn to handle different HTTP methods in Go by inspecting request methods, implementing conditional logic, and returning appropriate status codes in this 11-minute tutorial. Discover how to access the request method using r.Method and create branching logic to handle GET and POST requests differently. Master the use of Go's built-in constants like http.MethodGet and http.MethodPost instead of comparing against raw strings, and understand how to set proper status codes using WriteHeader for successful responses. Explore how to return 405 Method Not Allowed errors using http.Error when clients send unsupported methods, and learn the default behavior of returning 200 OK status when WriteHeader isn't explicitly called. Build upon foundational concepts of server setup, route handling, and response writing to create more sophisticated web handlers that can differentiate between methods on the same path, such as displaying forms with GET requests and processing form data with POST requests. Gain practical experience with status code management and error handling that prepares you for building real APIs and form handlers, with hands-on challenges and access to GitHub lesson materials for continued practice.
