Actix Remote IP extractor

Tiny extractor of remote user IP address, that handles reverse proxy.

The X-Forwarded-For header is automatically parsed when the request comes from a defined proxy, to determine the real remote client IP Address.

Note : regarding IPv6 addresses, the local part of the address is discarded. For example, the IPv6 client 2001:0db8:85a3:0000:0000:8a2e:0370:7334 will be returned as 2001:0db8:85a3:0000:0000:0000:0000:0000

Configuration

Configure it when you configure your Actix server:

rust HttpServer::new(move || { App::new() .app_data(web::Data::new(RemoteIPConfig { proxy: Some("IP".to_string()) })) // ... })

Usage

In your route, add a RemoteIP parameter:

```rust

[get("/")]

async fn home(remoteip: RemoteIP) -> HttpResponse { let ip: IpAddr = remoteip.0; // ... } ```
