First off, let’s say we have a class that provides access to our data: Let’s use all of these ideas to create a REST API. So when we say we’re creating a REST API, we just mean that we’re using REST ideas to create something that programmers can use to interact with our data. The point is that an API is a collection of things we can do when writing code. Similarly, the Java API is the list of classes and functions we use to write Java code. For example, Processing’s reference is an API: it’s the classes and functions we used to write Processing code. Do what makes sense to you and what works for your context.ĪPI stands for application programmer interface, which is a fancy name for whatever a programmer uses to interact with a language or library. You should treat REST as a tool, not as a strict set of rules that you must follow at all costs. The REST police aren’t going to come kick your door down if your code “violates” one of these rules. In other words, you should not store session information on the server! Everything needed to fulfill a request must be included in the request itself!Īll of these “rules” exist for a reason, but it’s important to keep in mind that in the end, everything is up to you. Or it could take a binary string, or XML, or a list of properties. The POST request might then take a JSON string. For example that GET request might return a JSON string that represents the user data.
