HTTP Methods

Learn to build GET and POST APIs using the FastAPI framework.

We'll cover the following...

HTTP GET is a request method to retrieve data from the server. An HTTP GET method should have the following characteristics:

  • Safe: It doesn’t change or modify the state of the server.
  • Idempotent: It doesn’t result in any side effects for the server.
  • Cacheable: It allows caching of the HTTP response.

Note: All safe methods are also idempotent.

We can easily build a simple HTTP GET API with the FastAPI framework.

Import

Start by adding the following import statements:

Python
from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware
app = FastAPI(
    title="Image Classification API",
    description="Working demo for building HTTP GET API server.",
    version="0.0.1"
)
print('The title of the application is:', app.title)

Cross-origin resource sharing (CORS)

CORS allows a frontend to load resources from a backend with a different origin. The implementation for CORS in FastAPI is as follows:

  1. Import the
