Project using#

Here is a simple way to kickstart your project with authx:

from fastapi import FastAPI, Depends, HTTPException
from authx import AuthX, AuthXConfig, RequestToken

app = FastAPI()

config = AuthXConfig(
     JWT_ALGORITHM = "HS256",
     JWT_SECRET_KEY = "SECRET_KEY",
     JWT_TOKEN_LOCATION = ["headers"],
)

auth = AuthX(config=config)
auth.handle_errors(app)

@app.get('/login')
def login(username: str, password: str):
     if username == "xyz" and password == "xyz":
          token = auth.create_access_token(uid=username)
          return {"access_token": token}
     raise HTTPException(401, detail={"message": "Invalid credentials"})

@app.get("/protected", dependencies=[Depends(auth.get_token_from_request)])
def get_protected(token: RequestToken = Depends()):
     try:
          auth.verify_token(token=token)
          return {"message": "Hello world !"}
     except Exception as e:
          raise HTTPException(401, detail={"message": str(e)}) from e
