For example, ProcessingвЂ™s reference is an API: itвЂ™s the classes and functions we used to write Processing code. Do what makes sense to you and what works for your context.ДЄPI 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 arenвЂ™t going to come kick your door down if your code вЂњviolatesвЂќ 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!ДЄll of these вЂњrulesвЂќ exist for a reason, but itвЂ™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.

You can represent data however you want.

You can use the other HTTP methods (like PUT or DELETE) to interact with the data as well. For example, youвЂ™d view AdaвЂ™s data by issuing a GET request to /people/Ada, and youвЂ™d modify AdaвЂ™s data by issuing a POST request to /people/Ada.

You use HTTP methods to access or change data.

For example, /users/Ada lets you access data about a person named Ada. ItвЂ™s more a way of using the concepts weвЂ™ve already learned. REST doesnвЂ™t actually involve any new technical concepts. REST stands for representational state transfer, which is just a fancy name for a set of rules that you can follow to build a web app that provides access to data in a way thatвЂ™s reusable by multiple applications, or many users of the same application. And instead of using HTML forms to create a POST request, it takes POST requests from other applications! (Of course, one of those applications could be another web app that gets user input using HTML forms!) REST The only difference is that instead of showing a website for a GET request, it provides data. To put it another way: a REST API is just a web app, very similar to all of the web apps weвЂ™ve already built. Then other applications would call your REST API, which lets you centralize all of your core logic in one place instead of rewriting it every time you wanted to create a new application. It would use SQL and JDBC to interact with the database, exactly like weвЂ™ve already learned about. This high-level diagram shows how you might organize your code: youвЂ™d have a database (or multiple databases), and your REST API would sit on top of that. Then other programs use your REST API to interact with your data. Your REST API is server code whose job it is to provide access to your data and to enforce rules like who can see what. This tutorial introduces the idea of creating a REST API, which is a way of organizing our code so we can access our data from multiple applications.

But what if we want to support different kinds of programs instead of just a web app? What if we want to create a desktop application or an Android app? How do we provide access to our data for those programs without writing everything from scratch each time?

We know how to get user input, how to access a database, and how to handle user logins. Now we know how to create a web app using servlet classes. Creating a REST API Creating a REST API tutorial java server rest ajax json
