get_fastapi_dependency

Get a FastAPI dependency function that can be used with Depends() to protect routes. The dependency tries each enabled auth method in order: Bearer token and Basic Auth.

Parameters

optional

boolDefaults to false

When True, unauthenticated requests pass through with {"authenticated": False} instead of raising a 401 error.

Returns

Callable — An async function suitable for use as a FastAPI dependency. Returns a dict with authenticated (bool) and method (str or None) keys.

Example

1 from fastapi import FastAPI, Depends
2 from signalwire.core.security_config import SecurityConfig
3 from signalwire.core.auth_handler import AuthHandler
4 
5 security = SecurityConfig()
6 auth = AuthHandler(security)
7 
8 app = FastAPI()
9 auth_dep = auth.get_fastapi_dependency()
10 
11 @app.get("/protected")
12 async def protected_route(auth_result=Depends(auth_dep)):
13     return {"method": auth_result["method"]}
14 
15 # Optional auth -- don't reject unauthenticated requests
16 optional_dep = auth.get_fastapi_dependency(optional=True)
17 
18 @app.get("/public")
19 async def public_route(auth_result=Depends(optional_dep)):
20     if auth_result["authenticated"]:
21         return {"user": "authenticated"}
22     return {"user": "anonymous"}
