This should be enough data to allow us to envision some potential research questions without overwhelming us as we focus on the design of our API. Client should only know URI of resource on server nothing else. Stateless Client-server interaction should be stateless in nature. There's also no TLS encryption handling. The value is the actual data. This can be in your Desktop folder, but I recommend creating a dedicated projects folder for this and similar projects.

How to write a web service using Python Flask This tutorial fills a sweet spot in the middle and demonstrates a structure that is simple, but Views should mostly represent the actions a consumer wants to see happen, while. This reduces system complexity and improves scalability. That means that our request will never reach the remote server; in fact. Layered System Layered system approach states that web service should follow layered approach, i. But at this moment, it can handle only one request.
