HTTP methods and HTTP status codes are two important concepts in web development.
HTTP methods
HTTP methods are used to indicate the desired action to be performed on a resource. The most common HTTP methods are:
- GET: Retrieves a resource.
- POST: Creates a new resource.
- PUT: Updates an existing resource.
- DELETE: Deletes a resource.
HTTP status codes
HTTP status codes are used to indicate the outcome of a request. The most common HTTP status codes are:
- 200 OK: The request was successful.
- 404 Not Found: The requested resource was not found.
- 500 Internal Server Error: An error occurred on the server.
How HTTP methods and HTTP status codes work together
When a client (such as a web browser) sends a request to a server, the server uses the HTTP method to determine what action to perform. The server then sends a response back to the client, which includes an HTTP status code to indicate the outcome of the request.
For example, if a client sends a GET request to the server for a specific web page, the server will retrieve the page and send it back to the client with a 200 OK status code. If the page is not found, the server will send back a 404 Not Found status code.
HTTP methods and HTTP status codes are an important part of the web. They allow clients and servers to communicate with each other in a standardized way.
