Surf is a friendly HTTP client built for casual Rustaceans and veterans alike.
It's completely modular, and built directly for `async/await`. Whether it's a
quick script, or a cross-platform SDK, Surf will make it work.

- Multi-platform out of the box
- Extensible through a powerful middleware system
- Reuses connections through the `Client` interface
- Fully streaming requests and responses
- TLS/SSL enabled by default
- Swappable HTTP backends
- HTTP/2 enabled by default

## Examples


```rust
#[async_std::main]

async fn main() -> surf::Result<()> {
    let mut res = surf::get("https://httpbin.org/get").await?;
    dbg!(res.body_string().await?);
    Ok(()) 
}
```

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

```rust
#[async_std::main]

async fn main() -> surf::Result<()> {
    dbg!(surf::get("https://httpbin.org/get").recv_string().await?);
    Ok(())
}
```

Both sending and receiving JSON is real easy too.

```rust
use serde::{Deserialize, Serialize};

#[derive(Deserialize, Serialize)]

struct Ip {
    ip: String
}

#[async_std::main]

async fn main() -> surf::Result<()> {
    let uri = "https://httpbin.org/post";
    let data = &Ip { ip: "129.0.0.1".into() };
    let res = surf::post(uri).body(surf::Body::from_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);

    Ok(())
}
```

And even creating streaming proxies is no trouble at all.

```rust
#[async_std::main]

async fn main() -> surf::Result<()> {
    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?;
    Ok(())
}
```

## Installation


Install OpenSSL - 
- Ubuntu - ``` sudo apt install libssl-dev ```
- Fedora - ``` sudo dnf install openssl-devel ```

Make sure your rust is up to date using: 
``` rustup update ```

With [cargo add](https://github.com/killercup/cargo-edit#Installation) installed :
```sh
$ cargo add surf
```

## Safety


This crate makes use of a single instance of `unsafe` in order to make the WASM
backend work despite the `Send` bounds. This is safe because WASM targets
currently have no access to threads. Once they do we'll be able to drop this
implementation, and use a parked thread instead and move to full multi-threading
in the process too.

## Thanks


Special thanks to [prasannavl](https://github.com/prasannavl) for donating the
crate name, and [sagebind](https://github.com/sagebind) for creating an easy to
use `async` curl client that saved us countless hours.
