"API Client" Exercise
Prerequisites
Business Prompt
In previous "grocery store" exercises, we have been processing grocery product data from a local CSV file. This allowed managers at different locations to keep their own inventory of products. But to improve consistency of record-keeping across stores, the store owner now wants managers at all stores to share the same inventory of products.
As a lead developer on your team, the professor has deployed the "Groceries API" web service to a public server available at https://groceries-api-csv.herokuapp.com. He explains, each store can use its own "API Client" application to issue HTTP requests to the API, and the API will perform the corresponding operations on a shared CSV inventory of products stored on the server.
Objective
Your objective is to write a command-line Python application that will allow users in any store to create, read, update, and destroy products from this shared inventory.
Challenges
First, read the API Documentation, which describes how to make requests to perform certain CRUD operations.
NOTE: You'll see some
curlexamples in there, but that is a command-line utility, and there aren't actually any Python code examples in there. The parts of the documentation you should focus on for each operation are: "what kind of request do I need to make?" (e.g. GET, POST, etc.), and "which URL do I make the request to?"
After consulting the docs, issue an appropriate HTTP request in Python to satisfy each of the challenges below.
List Products
API Documentation: List Products
Request information about all products, then loop through and print the "id" and "name" of each.
Show a Product
API Documentation: Show Product
Choose a product identifier from the list, then request information about that specific product, then print all the product's attributes.
Destroy a Product
API Documentation: Destroy Product
Request to delete the previously-selected product from the inventory.
Create a new Product
API Documentation: Create Product
Request to create a new product in the inventory.
Update a Product
API Documentation: Update Product
Request to update the new product you recently created.
