Is it possible to request a GET on a server's JSON file using a specific key?

I am currently working on a project involving an auto-suggestion exercise using a JSON file located on a server. I'm not entirely clear on the web development terminology, so one requirement has me a bit confused:

The requirement states: "On the keyup event (since there is an input field), issue a GET request to the server with the input key value and the name of a callback function as parameters."

While I have issued GET requests to JSON files on servers in the past, I am unsure how to send a key as a parameter for a JSON file. Is this even possible?

Answer №1

Understanding Web Terminology: Instead of issuing a GET Request for a file, you actually issue a GET request for a resource that is identified by a URL.

This is how the HTTP request line may appear:

GET /example/resource HTTP/1.0

In some cases, parameters can form part of the URL like so:

GET /example/resource?category=food&type=fruit HTTP/1.0

To gain a deeper understanding of URLs, refer to the RFC here:

In your initial scenario, perhaps the resource /example/resource.json initially appeared to be a static JSON file. However, for this particular exercise, it's likely necessary to have a program operational on the webserver that can output JSON data.
