FastAPI login in json: https://www.sheshbabu.com/posts/fastapi-structured-json-logging/

• The FastAPI framework: pip install fastapi
• The Uvicorn web server: pip install uvicorn
• The HTTPie text web client: pip install httpie
• The Requests synchronous web client package: pip install requests
• The HTTPX synchronous/asynchronous web client package: pip install httpx

from fastapi import FastAPI
app = FastAPI()
@app.get("/hi")
def greet():
  return "Hello? World?"

FastAPI itself does not include a web server but recommends Uvicorn. You can start Uvicorn and the FastAPI web application in two ways: externally or internally.

 uvicorn hello:app --reload

Start Uvicorn internally

from fastapi import FastAPI
app = FastAPI()
@app.get("/hi")
def greet():
  return "Hello? World?"
if __name__ == "__main__":
  import uvicorn
  uvicorn.run("hello:app", reload=True)

Test /hi in the browser

http://localhost:8000/hi

Test /hi with Requests

>>> import requests
>>> r = requests.get("http://localhost:8000/hi")
>>> r.json()

Test /hi with HTTPX, which is almost identical to Requests

>>> import httpx
>>> r = httpx.get("http://localhost:8000/hi")
>>> r.json()
