Difference between get and post method in Suitelet

In SuiteScript, specifically when working with Suitelets, GET and POST requests serve different purposes, similar to how they do in web development in general. Here’s how they differ in the context of a Suitelet.

1. GET Request:

• Purpose: Typically used for retrieving data or rendering a form or page to the user.
• Use Case: When you want to display something to the user, such as a form, HTML page, or data on the page.
• Example Scenario: Rendering a form that the user needs to fill out. The Suitelet responds with the form UI.
• Accessing Parameters: GET parameters are passed in the URL, and you can access them using request.parameters.
• Implementation: You handle GET requests inside the onRequest function by checking if request.method === 'GET'. You would typically use response.writePage() to render a page.

2. POST Request:

• Purpose: Used for submitting data to the server, usually after a user has filled out and submitted a form.
• Use Case: When you need to process data that the user has submitted, such as saving the data to a record or triggering some backend logic.
• Example Scenario: After a user fills out a form and submits it, the Suitelet processes the form data in the POST request.
• Accessing Parameters: POST parameters are sent in the body of the request, and you can access them using request.parameters.
• Implementation: You handle POST requests by checking if request.method === 'POST'. Here, you would typically process the form data or perform actions like creating or updating records.
