HTTP: Hypertext Transfer Protocol, a protocol used for distributed, collaborative, and hypertext information systems at the application layer. It is the foundation of data communication on the World Wide Web (WWW).

GET: An HTTP request method, commonly used to retrieve data from the server. It is characterized by small amounts of data and parameters passed through the URL.

POST: An HTTP request method, commonly used to submit data to the server. POST requests place data in the request body, allowing for larger amounts of data and offering higher security.

HTTP Header: A part of the metadata transmitted in HTTP requests and responses. They are key-value pairs that contain metadata about the client, server, request, and response. Common HTTP headers include:

• Content-Type: Specifies the media type of the message body.

• Content-Length: Specifies the byte length of the message body.

• Cookie: Transmits cookies to the server.

• Set-Cookie: Sets cookies on the client.

HTTP Body : The part of the message body in an HTTP request or response. The body type can be any type of data, such as text, JSON, XML, HTML, images and videos. This system usually uses JSON.

JSON (JavaScript Object Notation): A lightweight data exchange format based on text. JSON is language-independent, stored and represented in a human-readable and machine-parsable text format, which also facilitates machine generation. It effectively enhances network transmission efficiency. JSON data format uses a "name/value pair" approach and supports the representation of arrays.

sha256: sha256 is a widely used hashing algorithm for generating digital fingerprints, commonly used in cryptography and digital integrity verification fields.
