DiscountService

Current Version: 0.0.1

A PHP Microservice for calculating discounts on orders.

Introduction

DiscountService is written in PHP and was created as a test for Teamleader. It uses the Slim framework and an external (for this test fictional) API for fetching customer and product data.

Usage

To calculate a discount you can use the following request where you send a json-file with the order:

POST /api/order

The order you send should look something like this:

{
  "id": "1",
  "customer-id": "1",
  "items": [
    {
      "product-id": "B102",
      "quantity": "10",
      "unit-price": "4.99",
      "total": "49.90"
    }
  ],
  "total": "49.90"
}

And a json file will be returned looking like this:

{
    "id": "1",
    "customer-id": "1",
    "items": [
        {
            "product-id": "B102",
            "quantity": "12",
            "unit-price": "4.99",
            "total": "49.90",
            "amount-free-items": "2",
            "discount-description": "For every product of category  \"Switches\" (id 2), when you buy 5 you get one for free."
        }
    ],
    "total": "49.9"
}

Install the Service

Docker can be used to run the service. Go to the DiscountService-folder and executing the following command:

cd [directory-of-service]/DiscountService
docker-compose up

POST requests can then be sent to:

http://192.168.99.100:8080/api/order

The service can also be run locally without docker by doing the same steps, except using a different command

cd [directory-of-service]/DiscountService
php -S localhost:8080 -t public public/index.php

Here POST requests can be sent to:

http://localhost:8080/api/order
