Dependency Aliases

If you are familiar with FastAPI Dependency Injection system, you know you need to import the Depends object to declare a dependency. Since AuthX is designed to work with FastAPI, we provide quick aliases to get the most accessed dependencies.

The following example demonstrate how AuthX aliases can help you reduce verbosity.

Without aliasesWith aliases

from fastapi import FastAPI, Depends
from authx import AuthX

app = FastAPI()
security = AuthX()
security.handle_errors(app)

@app.get('/', dependencies=[Depends(security.access_token_required)])
def root(subject = Depends(security.get_current_subject), token = Depends(security.get_token_from_request)):
    ...

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()
security.handle_errors(app)

@app.get('/', dependencies=[security.ACCESS_REQUIRED])
def root(subject = security.CURRENT_SUBJECT, token = security.RAW_ACCESS_TOKEN):
    ...

Aliases

ACCESS_REQUIRED

• TokenPayload

Returns the access token payload if valid. Enforce the access token validation

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

@app.get('/protected')
def protected(payload = security.ACCESS_REQUIRED):
    return f"Your Access Token Payload is {payload}"

ACCESS_TOKEN

• RequestToken

Returns the encoded access token. DOES NOT Enforce the access token validation

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

# Use route dependency to enforce validation in conjunction with ACCESS_TOKEN
@app.get('/protected', dependencies=[security.ACCESS_REQUIRED])
def protected(token = security.ACCESS_TOKEN):
    return f"Your Access Token is {token}"

REFRESH_REQUIRED

• TokenPayload

Returns the refresh token payload if valid. Enforce the refresh token validation

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

@app.get('/refresh')
def refresh(payload = security.REFRESH_REQUIRED):
    return f"Your Refresh Token Payload is {payload}"

REFRESH_TOKEN

• RequestToken

Returns the encoded refresh token. DOES NOT Enforce the refresh token validation

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

# Use route dependency to enforce validation in conjunction with REFRESH_TOKEN
@app.get('/refresh', dependencies=[security.REFRESH_REQUIRED])
def refresh(token = security.REFRESH_TOKEN):
    return f"Your Refresh Token is {token}"

FRESH_REQUIRED

• TokenPayload

Returns the access token payload if valid & FRESH. Enforce the access token validation

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

@app.get('/protected', dependencies=[security.FRESH_REQUIRED])
def protected():
    return "Congratulations! Your have a fresh and valid access token."

CURRENT_SUBJECT

• Any

Returns the current subject. Enforce the access token validation

Note

You must set a subject getter to use this dependency. See Callbacks > User Serialization

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

@app.get('/whoami')
def whoami(subject = security.CURRENT_SUBJECT):
    return f"You are: {subject}"

BUNDLE / DEPENDENCY

• AuthXDependency

Returns the AuthXDependency dependency bundle to be used within the route

example

from fastapi import FastAPI
from authx import AuthX

app = FastAPI()
security = AuthX()

@app.get('/create_token')
def create_token(auth = security.BUNDLE):
    token = auth.create_access_token(uid="test")
    auth.set_access_cookie(token)
    return "OK"
