# 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 = "0.10.0-alpha.1"
actix-web = "3.0.0-alpha.1"
actix-webfinger = "0.3.0-alpha.5"
```
Then use it in your application
#### Client Example
```rust
use actix_web::client::Client;
use actix_webfinger::Webfinger;
use std::error::Error;
#[actix_rt::main]
async fn main() -> Result<(), Box<dyn Error>> {
let client = Client::default();
let wf = Webfinger::fetch(&client, "asonix@asonix.dog", "localhost:8000", false).await?;
println!("asonix's webfinger:\n{:#?}", wf);
Ok(())
}
```
#### Server Example
```rust
use actix_web::{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;
impl Resolver for MyResolver {
type State = Data<MyState>;
type Error = actix_web::error::JsonPayloadError;
fn find(
account: &str,
domain: &str,
state: &Data<MyState>,
) -> Pin<Box<dyn Future<Output = Result<Option<Webfinger>, Self::Error>>>> {
let w = if 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>> {
HttpServer::new(|| {
App::new()
.data(MyState {
domain: "asonix.dog".to_owned(),
})
.service(actix_webfinger::resource::<_, MyResolver>())
})
.bind("127.0.0.1:8000")?
.run()
.await?;
Ok(())
}
```
