Hello, week-9. I want to post a blog to quickly review the API topic to learn more about REST calls. I got confused; I researched about it. It has the Understanding And Using REST APIs.


 

What is a REST API

 

API (Application Programming Interface) - A set of rules allows programs to support any other. The developer creates the API on the server and enables the client to speak to it. 

The REST (Representational State Transfer) determines how the API. It is a set of rules that developers follow when they create their API. One of the rules states that one should get data (called a resource) when linking to a specific URL. Each URL made a request, while the data sent back to is called a response.


The Anatomy Of A Request #

It’s important to know that a request with four points:

  • The endpoint
  • The method
  • The headers
  • The data (or body)

 

The endpoint - URL that requests for (root-endpoint/?). The root-endpoint is the starting point of the API that is ordering.


The path determines the resource request. For example, it is like an automatic answering machine. That asks to press 1 for service, press 2 for another service, 3 for yet another service, and so on.


The Method

The method is the type of request sent to the server:

  • GET - Request to get a resource from a server. It will perform a `GET` request; the server looks for the requested data and sends it back.
  • POST - Request to create a new resource on a server. It performs a `POST` request, the server creates a new entry in the database and tells whether the creation is successful.
  • PUT & PATCH - Requests to update a resource on a server. If performing a `PUT` or `PATCH` request, the server updates an entry in the database and tells whether the update is successful.
  • DELETE - Request to delete a resource from a server. If performing a `DELETE` request, the server deletes an entry in the database and tells whether the deletion is successful.

These methods provide meaning for the request made. Perform steps: Create, Read, Update and Delete (CRUD).


The HEAD: it used to provide information to both the client and server. It has many purposes, such as authentication and giving information about the body content. It can find a list of valid headers on MDN’s HTTP Headers Reference.


The Data - contains information sent to the server. It only used POST, PUT, PATCH, or DELETE requests.

    This information supports me in learning and understanding the topic for the CS course. The material can students expect to apply what was learned in their future practice by small subject containing many types of information.

Hello, I am doing some class activities and looking over some questions ahead to save time for a thing or two. I came across the word "Behavioral Patterns" in class Act. 4 (Model 8); I got curious and looked it up. I found two articles that helped me understand the purposes, Problems with solutions, Real-World Analogy, Structure, Pseudo-code, Applicability, How to Implement, Pros and Cons, Relations with Other Patterns. The Behavioral Patterns are concerned with providing solutions. It is about object interaction - how they communicate, how some are dependent on others, how to separate them to be both dependent and independent, and give both flexibility and testing capabilities—also, the assignment of responsibilities between objects. The Behavioral Patterns cover many small parts to form the full extend of patterns. Like Interpreter, Template Method/Pattern, Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, and Visitor. Interpreter The...

Hello, Everyone. How are you guys doing? This past week, I read some articles or news related to CS (Computer Science). I finally picked a topic that caught my attention; engineers create 3D-printed objects that sense how users interact. My reason for why and seeing how choosing this article is because it looks cool and relatable for Gamers to use any controller made of small rubber pieces.    Short Summary : The researchers found a way to combine sensing capabilities into 3D printable structures made of constant cells, enabling designers to prototype interactive input devices quickly. Even, Formed a new method to 3D print mechanisms that detect how force applies to an object. Or The structures are made from a single piece of material so that they can be rapidly prototypes. Also, A designer could use this method to 3D print "interactive input devices," as a joystick or a controller. For accomplishing the goal, the researchers blended electrodes into structures made from metam...
