protect-salvo
Authorization extension for
salvo
to protect your endpoints.
To check user access to specific services, you can use built-in proc-macro
or manual.
The library can also be integrated with third-party solutions (e.g. jwt-middlewares).
How to use
-
Add
tower-compat
feature tosalvo
dependency in yourCargo.toml
-
Declare your own authority extractor
The easiest way is to declare a function with the following signature (trait is already implemented for such Fn):
use salvo::prelude::*;
// You can use custom type instead of String
// It requires to use hyper's `Request` & `Response` types, because integration is based on `tower`
pub async fn extract(req: &mut salvo::hyper::Request<ReqBody>) -> Result<HashSet<String>, salvo::hyper::Response<ResBody>>
- Add middleware to your application using the extractor defined in step 1
Router::with_path("/")
.hoop(GrantsLayer::with_extractor(extract).compat())
.push(Router::with_path("/endpoint").get(your_handler))
Steps 2 and 3 can be replaced by custom middleware or integration with another libraries.
- Protect your endpoints in any convenient way from the examples below:
Example of proc-macro
way protection
#[protect_salvo::protect("ROLE_ADMIN")]
#[handler]
async fn macro_secured() -> &'static str {
return "Hello, World!";
}
Example of ABAC-like protection and custom authority type
Here is an example using the ty
and expr
attributes. But these are independent features.
expr
allows you to include some checks in the macro based on function params, it can be combined with authorities by
using all
/any
.
ty
allows you to use a custom type for th authorities (then the middleware needs to be configured).
use enums::Role::{self, ADMIN};
use dto::User;
#[post("/info/{user_id}")]
#[protect_salvo::protect(any("ADMIN", expr = "user.is_super_user()"), ty = "Role")]
async fn admin_or_super_user(user: User) -> &'static str {
"some secured response"
}
Example of manual way protection
use protect_salvo::authorities::{AuthDetails, AuthoritiesCheck};
async fn manual_secure(details: AuthDetails) -> &'static str {
if details.has_authority(ROLE_ADMIN) {
return "ADMIN_RESPONSE";
}
"OTHER_RESPONSE"
}
