Day 11 : FastAPI Auth: Login with JWT & Route Protection

Day 11 of the FastAPI Zero to Hero series covers authentication and route protection, essential for a production-ready app.
Authentication is crucial to prevent unauthorized access to sensitive data and actions.
Topics covered include Basic Auth vs OAuth2 Password Flow, JWT (JSON Web Token) usage, login endpoint creation, and route protection.
Basic Auth sends username and password with every request, while OAuth2 Password Flow issues JWT tokens for subsequent requests.
JWT is a self-contained token with user data, expiry time, and issuer information signed for server verification.
Libraries like python-jose handle JWT encoding, decoding, and verification, while passlib with bcrypt ensures secure password hashing.
The project structure includes main.py for app definition, /token login route, /dashboard protected route, and auth.py for JWT utility functions.
The article provides code snippets for creating access tokens, decoding tokens, user authentication, and protecting routes using JWT tokens in FastAPI.
Steps to run the app locally with Uvicorn, access Swagger UI for testing endpoints, and authentication flow testing are outlined.
By understanding these concepts, you can build a robust authentication system in FastAPI for securing APIs.

3443. Maximum Manhattan Distance After K Changes

Given a string s representing movements on an infinite grid with 'N', 'S', 'E', and 'W' characters, find the maximum Manhattan distance from the origin that can be achieved by changing at most k characters.
Approach involves iterating through the string, updating position based on directions, calculating Manhattan distance at each step, accounting for changes allowed, and updating the maximum distance accordingly.
The solution efficiently determines the maximum Manhattan distance with the constraint of at most k changes to the movement directions in the string.
The algorithm runs in linear time, making it suitable for large inputs.
Example scenarios such as changing 'S' to 'N' in 'NWSE' to get a distance of 3 and changing 'NSWWEW' result in an output of 6 are provided.
Constraints include 1 <= s.length <= 105 and 0 <= k <= s.length, with hints suggesting brute forcing directions and maximizing distance changes.
The algorithm involves optimizing movements by potentially changing directions to increase the Manhattan distance from the origin.
Code example in PHP showcases the implementation and testing with test cases to demonstrate the solution.
The approach efficiently balances distance optimization with the constraints of allowed changes and total movements in the string.
The solution offers a systematic way to determine the maximum Manhattan distance achievable with limited direction changes.

Getting Started with Clap: A Beginner's Guide to Rust CLI Apps

Rust makes building powerful, safe, and efficient command-line apps easy, especially with the clap crate.
Clap is the most popular Rust crate for building CLI apps, handling parsing arguments, input validation, help messages, subcommands, and more.
Clap can be defined either by describing a struct (derive-style) or building it manually (builder-style).
Other ways to parse CLI args in Rust include std::env::args(), getopts, and structopt.
Traits like Parser and ValueEnum in Rust help with CLI parsing and enum handling.
The Parser trait in clap provides features like parsing CLI args, error handling, and custom parsing sources.
Attributes like #[command(...)] and #[arg(...)] in clap define app metadata and fine-tune CLI options.
ValueEnum in clap allows parsing enum values from strings and provides error handling for invalid values.
Common derive traits in Rust include Parser, ValueEnum, Debug, and Clone for functionality and debugging support.
Clap supports both derive and builder styles for defining CLI apps.
Recap of clap functionalities: defining CLI arguments, parsing inputs, validating, using enums, getting help/version output, and adding app metadata.
An example of a file checker CLI app using clap is provided.
Clap is recommended for building clean, safe, and powerful CLI tools in Rust, offering ease of use and minimal boilerplate code.
Traits like Parser and ValueEnum in clap facilitate building command-line interfaces with minimal setup.
