Rust开源HyperSwitch实战指南

Rust 的开源 HyperSwitch 的实用

以下是基于 Rust 的开源 HyperSwitch 的实用实例，涵盖不同应用场景和功能模块。这些示例通过代码片段和配置说明展示 HyperSwitch 的核心功能。

基本 HTTP 服务器

use hyperswitch::prelude::*;

#[tokio::main]
async fn main() {
    let server = Server::bind("127.0.0.1:8080").await.unwrap();
    server.serve(|_req| async { Ok("Hello, HyperSwitch!") }).await.unwrap();
}

路由配置

use hyperswitch::router::{Router, Method};

let mut router = Router::new();
router.add_route(Method::GET, "/home", |_req| async { Ok("Home Page") });
router.add_route(Method::POST, "/submit", |_req| async { Ok("Form Submitted") });

中间件示例

use hyperswitch::middleware::{Middleware, Next};

struct LogMiddleware;
impl Middleware for LogMiddleware {
    async fn call(&self, req: Request, next: Next) -> Result<Response> {
        println!("Request: {:?}", req);
        next.run(req).await
    }
}

JSON 响应

use hyperswitch::response::Json;

async fn handle_json(_req: Request) -> Result<Response> {
    let data = serde_json::json!({ "status": "su***ess" });
    Ok(Json(data).into())
}

静态文件服务

use hyperswitch::serve_static;

let server = Server::bind("127.0.0.1:8080").await.unwrap();
server.serve(serve_static("public/")).await.unwrap();

WebSocket 支持

use hyperswitch::ws::{WebSocket, Message};

async fn handle_ws(ws: WebSocket) {
    ws.on_message(|msg: Message| async move {
        println!("Received: {:?}", msg);
    }).await;
}

数据库集成（PostgreSQL）

use hyperswitch::db::postgres::PgPool;

let pool = PgPool::connect("postgres://user:pass@localhost/db").await.unwrap();
let row: (i64,) = sqlx::query_as("SELECT $1").bind(42).fetch_one(&pool).await.unwrap();

认证中间件

use hyperswitch::auth::{AuthMiddleware, ApiKey};

let auth = AuthMiddleware::new(ApiKey::new("SECRET_KEY"));
router.add_middleware(auth);

速率限制

use hyperswitch::ratelimit::{RateLimiter, MemoryStore};

let limiter = RateLimiter::new(MemoryStore::new(), 100, Duration::from_secs(60));
router.add_middleware(limiter);

日志记录

use hyperswitch::log::Logger;

let logger = Logger::new();
router.add_middleware(logger);

错误处理

use hyperswitch::error::Error;

async fn handle_error(_req: Request) -> Result<Response, Error> {
    Err(Error::NotFound("Route not found".into()))
}

HTTPS 配置

use hyperswitch::tls::{TlsConfig, Certificate};

let tls = TlsConfig::new()
    .cert(Certificate::from_file("cert.pem"))
    .key("key.pem");
Server::bind_tls("127.0.0.1:443", tls).await.unwrap();

测试路由

use hyperswitch::test::TestClient;

let client = TestClient::new(router);
let response = client.get("/home").send().await;
assert_eq!(response.status(), 200);

环境变量配置

use hyperswitch::config::Config;

let config = Config::from_env().unwrap();
Server::bind(&config.server.addr).await.unwrap();

健康检查端点

router.add_route(Method::GET, "/health", |_req| async { Ok("OK") });
