In FastAPI, a request is an object that contains information about an incoming HTTP request, such as the headers, query parameters, and the request body. A response is an object that contains information about the outgoing HTTP response, such as the headers, status code, and response body.
Handling incoming requests and outgoing responses is important in FastAPI because it allows us to build web applications that can communicate with other applications and services. Incoming requests contain data that our application needs to process, while outgoing responses contain data that our application needs to send back to the client.
FastAPI provides a simple and intuitive way to handle incoming requests and outgoing responses. It allows us to define the request and response bodies using Pydantic models, which makes it easy to validate and document the data sent and received in the request and response.
This series of tutorials will help you learn these things, step by step, in order from basic to advanced, from simple to complex.
