Add the following functions at the end of the app/utils.py file: The only difference between these two functions is that the expiration time for refresh tokens is longer than for access tokens. It handles both synchronous and asynchronous operations and has built-in support for data validation, authentication, and interactive API documentation powered by OpenAPI. That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc. It will go and look in the request for that Authorization header, check if the value is Bearer plus some token, and will return the token as a str. In this article, let's implement the logic, and . Here tokenUrl="token" refers to a relative URL token that we haven't created yet.

But let's save you the time of reading the full long specification just to find those little pieces of information you need. FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.. readme.md. This is because currently we don't have any protected endpoint, so the OpenAPI schema does not have enough information about the login strategy we are using. If not, you can always run this repl and play around with it or visit this deployed version. At Intility we use FastAPI for both internal (single-tenant) and customer-facing (multi-tenant) APIs. It is quite an extensive specification and covers several complex use cases. I read about authentication, Given an approach to write user: str = Depends(get_current_user) for each every function. Our authentication logic will be relying on jwt tokens. View Github Even if a person is logged in he/she may not have the necessary permissions. So user-name or email wouldn't work. Create another file app/deps.py and add include the following function in it: Here we are defining the get_current_user function as a dependency which in turn takes an instance of OAuth2PasswordBearer as a dependency. The get_hashed_password function takes a plain password and returns the hash for it that can be safely stored in the database. In this example we are going to use OAuth2, with the Password flow, using a Bearer token. By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems. Save this file locally as <project-name>_service_account .

Create a file named utils.py in the app directory and add the following function to hash user passwords. OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation). It boasts of In FastAPI, protected endpoints are handled using dependency injection and FastAPI can infer this from the OpenAPI schema and reflect it in the swagger docs. This endpoint is a bit different from the other post endpoints where you defined the schema for filtering incoming data. In that case, FastAPI also provides you with the tools to build it.

Build the Dockerfile: docker build -t fastapi . And the spec says that the fields have to be named like that. We can use OAuth2 to build that with FastAPI. Several of these flows are appropriate for building an OAuth 2.0 authentication provider (like Google, Facebook, Twitter, GitHub, etc): But there is one specific "flow" that can be perfectly used for handling authentication in the same application directly: This automatic discovery is what is defined in the OpenID Connect specification. On the negative side, FastAPI lacks some complex features like out of the box user management and admin panel that come baked in with Django.
