Surf the web - HTTP client framework

Surf is a Rust HTTP client built for ease-of-use and multi-HTTP-backend flexibility. Whether it’s a quick script, or a cross-platform SDK, Surf will make it work.

Extensible through a powerful middleware system
Multiple HTTP back-ends that can be chosen
Reuses connections through a configurable Client interface
Fully streaming requests and responses
TLS enabled by default (native tls or rustls)
Built on async-std (with optional tokio support)

Examples

let mut res = surf::get("https://httpbin.org/get").await?;
dbg!(res.body_string().await?);

It’s also possible to skip the intermediate Response, and access the response type directly.

dbg!(surf::get("https://httpbin.org/get").recv_string().await?);

Both sending and receiving JSON is real easy too.

#[derive(Deserialize, Serialize)]
struct Ip {
    ip: String
}

let uri = "https://httpbin.org/post";
let data = &Ip { ip: "129.0.0.1".into() };
let res = surf::post(uri).body_json(data)?.await?;
assert_eq!(res.status(), 200);

let uri = "https://api.ipify.org?format=json";
let Ip { ip } = surf::get(uri).recv_json().await?;
assert!(ip.len() > 10);

And even creating streaming proxies is no trouble at all.

let req = surf::get("https://img.fyi/q6YvNqP").await?;
let body = surf::http::Body::from_reader(req, None);
let res = surf::post("https://box.rs/upload").body(body).await?;

Setting configuration on a client is also straightforward.

use std::convert::TryInto;
use std::time::Duration;
use surf::{Client, Config};
use surf::Url;

let client: Client = Config::new()
    .set_base_url(Url::parse("http://example.org")?)
    .set_timeout(Some(Duration::from_secs(5)))
    .try_into()?;
    
let mut res = client.get("/").await?;
println!("{}", res.body_string().await?);

Features

The following features are available. The default features are curl-client, middleware-logger, and encoding

curl-client (default): use curl (through isahc) as the HTTP backend.
h1-client: use async-h1 as the HTTP backend with native TLS for HTTPS.
h1-client-rustls: use async-h1 as the HTTP backend with rustls for HTTPS.
hyper-client: use hyper (hyper.rs) as the HTTP backend.
wasm-client: use window.fetch as the HTTP backend.
middleware-logger (default): enables logging requests and responses using a middleware.
encoding (default): enables support for body encodings other than utf-8.
