有没有在Actix路由级别实现身份验证/授权检查的好方法？

[dependencies]
actix-identity = "0.4"
actix-guards = "0.4"

use actix_identity::IdentityService;

fn main() {
    HttpServer::new(|| {
        App::new()
            .wrap(IdentityService::new(
                CookieIdentityPolicy::new(&[0; 32])
                    .name("auth-cookie")
                    .secure(false),
            ))
            // ...
    })
    .bind("127.0.0.1:8080")
    .unwrap()
    .run()
    .unwrap();
}

use actix_web::{get, web, App, HttpResponse, HttpServer};
use actix_identity::Identity;
use actix_guards::Guard;

struct AuthGuard;

impl Guard for AuthGuard {
    fn check(&self, identity: Option<&Identity>) -> bool {
        // 在这里执行身份验证/授权检查逻辑
        // 如果身份验证/授权检查通过，返回true；否则返回false
        true
    }
}

#[get("/protected")]
async fn protected_route(id: Identity) -> HttpResponse {
    HttpResponse::Ok().body("Protected route")
}

#[get("/public")]
async fn public_route() -> HttpResponse {
    HttpResponse::Ok().body("Public route")
}

fn main() {
    HttpServer::new(|| {
        App::new()
            .service(web::scope("/api")
                .service(protected_route)
                .service(public_route)
                .guard(AuthGuard)
            )
    })
    .bind("127.0.0.1:8080")
    .unwrap()
