A simple contrived example of a FastAPI application that heavily uses
the FastAPI dependency injection system.

Sample request http://127.0.0.1:9876/tasks?user_id=123456
returns [{"id":1,"name":"Task 1","user":{"id":123456,"name":"John Doe"}}]

Problem: FastAPI doesn't accept JSON-encoded pydantic models in query strings. See #884.

Solution: Use json_param() from the snippet below.

Usage example.

from fastapi import FastAPI

An ad-hoc script to analyze the percentage of the topic-specific questions for
each programming language.

For each language, the script downloads two pages and looks for the number of questions
in the title, like "NNN,NNN questions". For example, for "python" and
an extra tag "architecture", the script downloads
https://stackoverflow.com/questions/tagged/python and
https://stackoverflow.com/questions/tagged/python+architecture.

This is a simple implementation for TCP server and client. The server listens for the port 9090 of the localhost, receives messages from any connected clients, and sends them to all connected peers. The client is started with a username as an argument, reads in an infinite loop messages from the string, re-format them as "name > message\n" and send to the server. In a different async function it also waits for message from the server and prints the to the console.

Files:

• aio_chat_client.py: client implementation
• aio_chat_server.py: server implementation

Dependencies: Python 3.6+ and aioconsole
