What's the deal with HTTP Request methods and AJAX?

I'm currently developing a function that streamlines the process of sending XMLHttpRequests.

This function is structured as follows:

XHR(url, method, data);

For example, if we call:

XHR('Hey.xml', 'get', { hi: 'hey' });

The result would be a request for "Hey.xml?hi=hey".

However, the challenge lies in the fact that different request methods handle query strings differently.

GET and HEAD require the query to be included in the URL itself.

On the other hand, POST needs the query to be sent with the following syntax:

request.send(query);

I'm aware that there are additional request methods available, and I am curious about how they handle query strings. Do they follow one of these patterns, or is there another approach entirely?

And before you suggest it, yes, I know there are already plenty of similar functions out there, including jQuery. But please refrain from recommending it.

Answer №1

After doing some research on AJAXPatterns.org, I discovered that there are no distinctions in the usage of "other" request methods with XHR.

Answer №2

Actually, there are additional HTTP methods besides GET and POST. PUT and DELETE are also part of the mix, although they are not as commonly utilized as the former two. GET is typically the only method that can be used across different domains, while PUT, POST, and DELETE are restricted to your own domain. Ultimately, the choice between using POST, PUT, or DELETE depends on your specific needs and circumstances.
