Good morning! And happy holidays! 🎄
Today I bring you a basic tutorial about HTTP status codes.
It’s always good to have them handy, so here are the most common ones!
Common HTTP status codes:
- 200 OK: The request has been successfully processed.
- 400 Bad Request: Error in the client’s request. It could be due to incorrect syntax or invalid data.
- 404 Not Found: The requested resource was not found on the server.
- 500 Internal Server Error: Server issues while processing the client’s request.
- 503 Service Unavailable: The server cannot handle the request due to overload or maintenance.
Brief explanation of each one:
- 200 OK: Everything is fine, the request was successful.
- 400 Bad Request: Something is wrong in the request sent by the client.
- 404 Not Found: The requested resource is not available on the server.
- 500 Internal Server Error: The server encountered an unexpected situation.
- 503 Service Unavailable: The server cannot handle the request at the moment.
What to do if you encounter these errors?
- 200 OK: Everything is fine.
- 400 Bad Request: Check the syntax and data of the request you are sending.
- 404 Not Found: Make sure the URL is correct and the resource exists on the server.
- 500 Internal Server Error: Contact the server administrator.
- 503 Service Unavailable: Wait a bit and try again later.
I hope this guide helps you better understand these HTTP status codes!
Here’s a fun example to help you better understand these errors:
Imagine you’re in a café (your browser) and you ask the waiter (web server) for a coffee (web page).
- 200 OK: The waiter brings you the coffee correctly, everything is fine.
- 400 Bad Request: You ask the waiter for a coffee with ingredients that don’t exist, like coffee with cheese. He can’t fulfill your request because it’s confusing or incorrect.
- 404 Not Found: You request a coffee that is not on the menu. The waiter can’t find that option.
- 500 Internal Server Error: The waiter gets confused and doesn’t know how to prepare the coffee you requested.
- 503 Service Unavailable: There are so many people in the café that the waiter is overloaded and temporarily unable to attend to your order.
These status codes are like the responses you would get when ordering something in a café; they indicate whether your request was successful or if there is any problem.
I hope you like it and find it useful! 💡
