How Write a python program to retrieve all the products from the API Server

Question

Suppose you are writing a python web client to access an API of an online supermarket. Given below are the API details.

Base URL = http://host1.open.uom.lk:8080

Write a python program to retrieve all the products from the API Server and print the total number of products currently stored in the server.

Hint: the json response will be of the following example format:

{
  "message": "success",
  "data": [
    {
      "id": 85,
      "productName": "Araliya Basmathi Rice",
      "description": "White Basmathi Rice imported from Pakistan. High-quality rice with extra fragrance. Organically grown.",
      "category": "Rice",
      "brand": "CIC",
      "expiredDate": "2023.05.04",
      "manufacturedDate": "2022.02.20",
      "batchNumber": 324567,
      "unitPrice": 1020,
      "quantity": 200,
      "createdDate": "2022.02.24"
    },
    {
      "id": 86,
      "productName": "Araliya Basmathi Rice",
      "description": "White Basmathi Rice imported from Pakistan. High-quality rice with extra fragrance. Organically grown.",
      "category": "Rice",
      "brand": "CIC",
      "expiredDate": "2023.05.04",
      "manufacturedDate": "2022.02.20",
      "batchNumber": 324567,
      "unitPrice": 1020,
      "quantity": 200,
      "createdDate": "2022.02.24"
    }
  ]
}

Great! So it sounds like you were able to fetch the JSON response successfully.
Mind you, response_API is NOT the JSON, it is just a Response object. You need to call .json() or .text() on it to get the result you intend. Check this out: https://www.w3schools.com/python/ref_requests_response.asp

You’ll now need to parse the JSON string into a useable Python data structure.

Here is information for parsing JSON: https://www.w3schools.com/python/gloss_python_json_parse.asp

parsed = json.load(response_API.text())

JSON is parsed into a dictionary. Here you can access the “data” key, which is a list of products. We can simply get the length of a list.

len(parsed[“data”])
