Hi 🙂🖐

Welcome to a new post, Today I will share with you how to set cookies in a web browser in FastAPI and Python in an easy way.

step 1

Import modules

from fastapi import FastAPI, Response, Request, Depends from fastapi.responses import HTMLResponse from secrets import token_hex
Enter fullscreen mode Exit fullscreen mode

step 2

Create HTML file for test

<html> <head></head> <body> <h1>This is test</h1> </body> </html>
Enter fullscreen mode Exit fullscreen mode

step 3

Create test route

app = FastAPI() @app.get('/test') async def test(response: Response): response = HTMLResponse(open('test.html', 'r').read()) response.set_cookie(key="fakesession", value=token_hex(20)) return response
Enter fullscreen mode Exit fullscreen mode

run the API 

uvicorn main:app --reload
Enter fullscreen mode Exit fullscreen mode

it's working 😎

If you want to confirm if it really working 🙃

you can delete the cookie and reload the page 🙂

Read the cookie from another page 

async def read_token(request : Request): token = request.cookies.get('fakesession') if not token: return False return token @app.get('/protected') async def protected(token : str = Depends(read_token)): return {'token': token}
Enter fullscreen mode Exit fullscreen mode
