Actix Permissions

Permission and input validation extension for Actix Web. Alternative to actix guard, with access to app data injections, HttpRequest and Payload. Permissions are flexible, take a look at Examples directory for some of the use cases.

You could write a permission check like a function or like a struct.
This code: rust async fn is_allowed( req: HttpRequest ) -> actix_web::Result<bool> { todo!(); } is almost the same as writing: ```rust struct IsAllowed;

impl Permission<()> for IsAllowed { type Future = Ready>;

fn call(&self, req: HttpRequest, ctx: ()) -> Ready<actix_web::Result<bool>> {
    todo!();
}

} ```

Example

Dependencies:
toml [dependencies] actix-permissions = "1.0.0-beta.1" Code: ```rust use actixpermissions::*; use actixweb::web::Data; use actix_web::*; use serde::Deserialize;

[derive(Debug, Clone, Deserialize)]

pub struct MyStatus { pub status: Option, }

async fn dummypermissioncheck( req: HttpRequest, dummyservice: web::Data, data: web::Query, ) -> actixweb::Result { // Unecessary complicating permission check to show what it can do. // You have access to request, payload, and all injected dependencies through appdata. Ok(dummy_service.check(data.status.clone())) }

struct DummyService;

impl DummyService { pub fn check(&self, value: Option) -> bool { value == Some("all".to_string()) } }

async fn index() -> Result { Ok("Hi there!".to_string()) }

[actix_web::main]

async fn main() -> std::io::Result<()> { HttpServer::new(|| { App::new() .appdata(Data::new(DummyService)) .service(web::scope("").route("/", check(web::get(), dummypermission_check, index))) }) .bind("127.0.0.1:8888")? .run() .await } ```

Use Cases

Take a look at Examples directory. You could use actix-permissions for role based authorization check, like in role-based-authorization example.
hello-world example is just a proof of concept, showing how you can set permission, access service request, payload and injected services.

Permission Deny

By default, 403 is returned for failed permission checks. You may want to toggle between Unauthorized and Forbidden, maybe customize 403 forbidden messages. That's why check_with_custom_deny is for. Take a look at role based authorization example for more info.
