Which RESTFul operation corresponds to the HTTP GET method?

Introduction

REST (Representational State Transfer) is an architectural style used for designing networked applications. It relies on HTTP (Hypertext Transfer Protocol) methods to perform operations on resources. One of the most commonly used HTTP methods in RESTful services is GET, which corresponds to the READ operation in CRUD (Create, Read, Update, Delete).

This article explores:

• The role of the HTTP GET method in RESTful operations.
• How it aligns with 1Z0-900 (Oracle Java EE 7 Web Services Developer) exam concepts.
• Why Study4Pass is an excellent resource for Oracle certification preparation.

Understanding RESTful Operations and HTTP Methods

What Are RESTful Operations?

RESTful web services use standard HTTP methods to interact with resources. The primary operations are:

The HTTP GET method is used for READ operations, meaning it retrieves data from a server without modifying it.

How HTTP GET Works in REST?

• Idempotent: Multiple identical GET requests return the same result.
• Safe: Does not change server state.
• Cacheable: Responses can be stored for efficiency.

Example:

GET /api/users/123 HTTP/1.1

Host: example.com

This request retrieves user details with ID 123.

HTTP GET in the 1Z0-900 Exam (Oracle Java EE 7 Web Services Developer)

The 1Z0-900 certification validates expertise in Java EE 7 web services, including RESTful APIs. Key topics related to HTTP GET include:

RESTful Annotations in Java (JAX-RS)

• @GET: Specifies that a method handles HTTP GET requests.
• @Path: Defines the URI path.
• @Produces: Indicates the response media type (e.g., JSON, XML).

Example Code:

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.MediaType;

@Path("/users")

public class UserResource {

@GET

@Path("/{id}")

@Produces(MediaType.APPLICATION_JSON)

public User getUser(@PathParam("id") int id) {

return UserService.findUserById(id);

}

}

Query Parameters and Path Parameters

• Path Parameters (/users/{id}) – Used for specific resource identification.
• Query Parameters (/users?name=John) – Used for filtering/sorting.

Best Practices for GET Requests

• Use Proper Status Codes:
• 200 OK (Success)
• 404 Not Found (Resource doesn’t exist)
• Avoid Sensitive Data in URLs (GET requests are logged in browser history).
