Axum Cookie Middleware

This library provides a middleware layer for integrating cookie management into Axum applications. It allows parsing cookies from incoming requests, managing cookies and setting Set-Cookie headers in HTTP responses.

Features

• Middleware integration with Axum.
• Flexible cookie parsing (strict or lenient mode).
• Thread-safe cookie management.
• Automatic handling of Set-Cookie headers.

Usage

Add the library to your Cargo.toml:

[dependencies]
...
+ axum-cookie = "0.2.3"

Example: Basic Integration

use axum::{Router, routing::get};
use axum_cookie::prelude::*;

async fn handler(cookie: CookieManager) -> &'static str {
    // Retrieve a cookie
    if let Some(cookie) = cookie.get("session") {
        println!("Cookie value: {}", cookie.value());
    }

    // Add a cookie
    cookie.add(Cookie::new("session", "abc123"));
    "Hello, cookies!"
}

let app: Router<()> = Router::new()
    .route("/", get(handler))
    .layer(CookieLayer::default());

Example: Strict Cookie Parsing

use axum::{Router, routing::get};
use axum_cookie::CookieLayer;

let app: Router<()> = Router::new()
    .route("/", get(|| async { "Strict mode enabled" }))
    .layer(CookieLayer::strict());

API

CookieManager

• CookieManager::new - Creates a new cookie manager with a specified CookieJar.
• CookieManager::add - Adds a cookie to the jar.
• CookieManager::remove - Removes a cookie by its name.
• CookieManager::get - Retrieves a cookie by its name.
• CookieManager::cookie - Returns all cookies in the jar.
• CookieManager::as_header_value - Generates Set-Cookie header value for all cookies in the jar.

CookieLayer
