Rocket Casbin Middleware
Casbin access control middleware for Rocket framework
Install
Add it to Cargo.toml
rocket-authz = "0.1.0"
Requirement
Casbin only takes charge of permission control, so you need to implement an Authentication Middleware
to identify user.
You need to put rocket_authz::CasbinVals
which contains subject
and domain
(optional) into reqeust.local_cache()
through an Authentication Middleware
. You could see an example of using rocket-authz in Example.
Example
#![feature(proc_macro_hygiene, decl_macro)]
use casbin::{DefaultModel, FileAdapter};
use rocket::{
fairing::{Fairing, Info, Kind},
get,
request::Request,
routes, Data,
};
use rocket_authz;
struct FakeAuthFairing;
impl Fairing for FakeAuthFairing {
fn info(&self) -> Info {
Info {
name: "Fake Auth Fairing",
kind: Kind::Request | Kind::Response,
}
}
fn on_request(&self, request: &mut Request, _data: &Data) {
request.local_cache(|| rocket_authz::CasbinVals::new(Some("alice".to_string()), None));
}
}
#[get("/data1")]
fn data1(_g: rocket_authz::CasbinGuard) -> &'static str {
"data1"
}
#[get("/data2")]
fn data2(_g: rocket_authz::CasbinGuard) -> &'static str {
"data2"
}
fn rocket() -> rocket::Rocket {
let rt = tokio::runtime::Runtime::new().unwrap();
let m = match rt.block_on(DefaultModel::from_file(
"examples/rbac_with_pattern_model.conf",
)) {
Ok(m) => m,
Err(_) => panic!(""),
};
let a = FileAdapter::new("examples/rbac_with_pattern_policy.csv");
let casbin_fairing = match rt.block_on(rocket_authz::CasbinFairing::new(m, a)) {
Ok(f) => f,
Err(_) => panic!(""),
};
let fake_auth_fairing = FakeAuthFairing;
rocket::ignite()
.attach(fake_auth_fairing)
.attach(casbin_fairing)
.mount("/", routes![data1, data2])
}
