# Actix Webfinger
|
|
A library to aid in resolving and providing webfinger objects with the Actix Web web framework.
|
|
|
|
- [Read the documentation on docs.rs](https://docs.rs/actix-webfinger)
|
|
- [Find the crate on crates.io](https://crates.io/crates/actix-webfinger)
|
|
- [Hit me up on Mastodon](https://asonix.dog/@asonix)
|
|
|
|
The main functionality this crate provides is through the `Webfinger::fetch` method for Actix
|
|
Web-based clients, and the `Resolver<S>` trait for Actix Web-based servers.
|
|
|
|
### Usage
|
|
First, add Actix Webfinger as a dependency
|
|
|
|
```toml
|
|
[dependencies]
|
|
actix-rt = "2.6.0"
|
|
actix-web = "4.0.0"
|
|
actix-webfinger = "0.4.0"
|
|
```
|
|
|
|
Then use it in your application
|
|
|
|
#### Client Example
|
|
```rust
|
|
use actix_webfinger::Webfinger;
|
|
use awc::Client;
|
|
use std::error::Error;
|
|
|
|
#[actix_rt::main]
|
|
async fn main() -> Result<(), Box<dyn Error>> {
|
|
let client = Client::default();
|
|
let wf = Webfinger::fetch(
|
|
&client,
|
|
Some("acct:"),
|
|
"asonix@localhost:8000",
|
|
"localhost:8000",
|
|
false,
|
|
)
|
|
.await?;
|
|
|
|
println!("asonix's webfinger:\n{:#?}", wf);
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
#### Server Example
|
|
```rust
|
|
use actix_web::{middleware::Logger, web::Data, App, HttpServer};
|
|
use actix_webfinger::{Resolver, Webfinger};
|
|
use std::{error::Error, future::Future, pin::Pin};
|
|
|
|
#[derive(Clone, Debug)]
|
|
pub struct MyState {
|
|
domain: String,
|
|
}
|
|
|
|
pub struct MyResolver;
|
|
|
|
type LocalBoxFuture<'a, Output> = Pin<Box<dyn Future<Output = Output> + 'a>>;
|
|
|
|
impl Resolver for MyResolver {
|
|
type State = Data<MyState>;
|
|
type Error = actix_web::error::JsonPayloadError;
|
|
|
|
fn find(
|
|
scheme: Option<&str>,
|
|
account: &str,
|
|
domain: &str,
|
|
state: Data<MyState>,
|
|
) -> LocalBoxFuture<'static, Result<Option<Webfinger>, Self::Error>> {
|
|
let w = if scheme == Some("acct:") && domain == state.domain {
|
|
Some(Webfinger::new(&format!("{}@{}", account, domain)))
|
|
} else {
|
|
None
|
|
};
|
|
|
|
Box::pin(async move { Ok(w) })
|
|
}
|
|
}
|
|
|
|
#[actix_rt::main]
|
|
async fn main() -> Result<(), Box<dyn Error>> {
|
|
std::env::set_var("RUST_LOG", "info");
|
|
pretty_env_logger::init();
|
|
HttpServer::new(|| {
|
|
App::new()
|
|
.app_data(Data::new(MyState {
|
|
domain: "localhost:8000".to_owned(),
|
|
}))
|
|
.wrap(Logger::default())
|
|
.service(actix_webfinger::resource::<MyResolver>())
|
|
})
|
|
.bind("127.0.0.1:8000")?
|
|
.run()
|
|
.await?;
|
|
|
|
Ok(())
|
|
}
|
|
```
