Rash v0.1.0 released!
https://github.com/pando85/rash
Rash It's a kind of reception Ansible Tool inspired Declarative Shell Scripting language .
- Avoid lengthy and unmanageable Shell Script
- similar Ansible Such a programming style
Declarative vs imperative：Imperative: entrypoint.sh:
#!/bin/bash
set -e
REQUIRED_PARAMS="
VAULT_URL
VAULT_ROLE_ID
VAULT_SECRET_ID
VAULT_SECRET_PATH
"
for required in $REQUIRED_PARAMS ; do
[[ -z "${!required}" ]] && echo "$required IS NOT DEFINED" && exit 1
done
echo "[$0] Logging into Vault..."
VAULT_TOKEN=$(curl -s $VAULT_URL/v1/auth/approle/login \
--data '{"role_id": "'$VAULT_ROLE_ID'","secret_id": "'$VAULT_SECRET_ID'"}' \
| jq -r .auth.client_token)
echo "[$0] Getting Samuel API key from Vault..."
export APP1_API_KEY=$(curl -s -H "X-Vault-Token: $VAULT_TOKEN" \
$VAULT_URL/v1/$VAULT_SECRET_PATH | jq -r .data.api_key)

Mun v0.2.0 Released
Mun v0.2.0 Released
https://github.com/mun-lang/mun/releases/tag/v0.2.0
Mun It's a pass iteration An embedded programming language that can continuously create iterations .Mun The idea of language comes from finding a way to avoid Lua The disadvantages of dynamic scripting language can be found in Rust In language hot-reload（ Thermal loading ） New programming language . therefore ,Mun First of all, a new language cannot be Rust Language competitors , At the same time, you can Rust Language （ or C/C++） Host language Seamlessly embed programming in .Mun Completely by Rust language , The main software package is rust-analyzer and rustc . The main features include ：
- Ahead of time compilation
- Statically typed
- First class hot-reloading
New version updated features ：
- Hot reloadable data structures
- Marshalling of data structures to Rust, C, and C++
- Garbage collection for data structures (with opt-out at the struct-level)
- loop, while, break and explicitreturn expressions
- Full operator support for numeric and boolean types
- Incremental compilation
- Benchmark support
Actix Casbin middleware
Actix Casbin Middleware
https://github.com/casbin-rs/actix-casbin-auth
Casbin yes Rust Language web page architecture actix-web framework Access control middleware .
install （install）
stay Cargo.toml Add the following ：
demand （requirement）
Casbin Only responsible for permission management , So we need to achieve Authentication Middleware To confirm the user . Therefore, it is necessary to put the subject(username) and domain(optional) The information of actix_casbin_auth::CasbinVals Add to Extension in .
Take the following example ：
use std::cell::RefCell;
use std::pin::Pin;
use std::rc::Rc;
use std::task::{Context, Poll};
use actix_service::{Service, Transform};
use actix_web::{dev::ServiceRequest, dev::ServiceResponse, Error, HttpMessage};
use futures::future::{ok, Future, Ready};
use actix_casbin_auth::CasbinVals;
pub struct FakeAuth;
impl<S: 'static, B> Transform<S> for FakeAuth
where
S: Service<Request = ServiceRequest, Response = ServiceResponse<B>, Error = Error>,
S::Future: 'static,
B: 'static,
{
type Request = ServiceRequest;
type Response = ServiceResponse<B>;
type Error = Error;
type InitError = ();
type Transform = FakeAuthMiddleware<S>;
type Future = Ready<Result<Self::Transform, Self::InitError>>;
fn new_transform(&self, service: S) -> Self::Future {
ok(FakeAuthMiddleware {
service: Rc::new(RefCell::new(service)),
})
}
}
pub struct FakeAuthMiddleware<S> {
service: Rc<RefCell<S>>,
}
impl<S, B> Service for FakeAuthMiddleware<S>
where
S: Service<Request = ServiceRequest, Response = ServiceResponse<B>, Error = Error> + 'static,
S::Future: 'static,
B: 'static,
{
type Request = ServiceRequest;
type Response = ServiceResponse<B>;
type Error = Error;
type Future = Pin<Box<dyn Future<Output = Result<Self::Response, Self::Error>>>>;
fn poll_ready(&mut self, cx: &mut Context) -> Poll<Result<(), Self::Error>> {
self.service.poll_ready(cx)
}
fn call(&mut self, req: ServiceRequest) -> Self::Future {
let mut svc = self.service.clone();
Box::pin(async move {
let vals = CasbinVals {
subject: String::from("alice"),
domain: None,
};
req.extensions_mut().insert(vals);
svc.call(req).await
})
}

let a = FileAdapter::new("examples/rbac_with_pattern_policy.csv"); //You can also use diesel-adapter or sqlx-adapter
let casbin_middleware = CasbinService::new(m, a).await;
casbin_middleware
.write()
.await
.add_matching_fn(key_match2)?;
HttpServer::new(move || {

.wrap(casbin_middleware.clone())
.wrap(FakeAuth)
.route("/pen/1", web::get().to(|| HttpResponse::Ok()))

})
.bind("127.0.0.1:8080")?
