Extract Parameters in a Service File | "GET" and "POST" Request

In this short tutorial article, we will go over how to extract parameters in a SuiteCommerce service file for a "GET" and "POST" request.

About "Get and "Post" Requests to Service Files

Both “GET” and “POST” requests to service files can contain data the requester passed along. Extracting this data is done differently based on the request. See the tutorial article SuiteScript2(SS2) Services for SuiteCommerce for the different ways to make a request.

Best Practice: Add validation of the incoming parameters!

The code block below shows how to extract parameters passed for each request type. Remember, “fetch” calls make a “GET” request, and “save” calls make a “POST” request (more info here).

Code Example: How to Extract the Parameters

define([], function () {
    "use strict";

    var response = {
        errors: [],
    };

    function service(context) {
        try {
            //Extract parameters from a "POST" request
            if (context.request.method == "POST") {
                var parameters = context.request.body ? JSON.parse(context.request.body) : {};
            }
            //Extract parameters from a "GET" request
            else if (context.request.method == "GET") {
                var parameters = context.request.parameters || {};
            }
        } catch (error) {
            response.errors.push(error);
        }

        context.response.write(JSON.stringify(response));
    }

    return {
        service: service,
    };
});
