HttpClient

httpclient is a user-friendly http client in Rust. Where possible, it closely mimics the reqwest API. Why build a new http client?

• httpclient::{Request, Response} objects are serde-serializable, which enables record/replay functionality. See the example below to see it in action.
• httpclient provides an API for user-extensible middleware. Built-in middleware includes redirect, retry, logging, and record/replay.
• httpclient provides a built-in Error type that can return the Http request, which includes the status code, headers, and response body.
• httpclient provides convenience methods that reqwest does not support. The most important is send_awaiting_body which awaits both the request and the response body, which greatly simplifies the scenario where you want to return the request body even in error cases.

Note: httpclient is under active development and is alpha quality software. While we make effort not to change public APIs, we do not currently provide stability guarantees.

Examples

#[tokio::main]
async fn main() {
    let mut client = httpclient::Client::new()
        // With this middleware, the script will only make the request once. After that, it replays from the filesystem
        // and does not hit the remote server. The middleware has different modes to ignore recordings (to force refresh)
        // and to prevent new requests (for running a test suite).
        // The recordings are sanitized to hide secrets.
        .with_middleware(httpclient::middleware::RecorderMiddleware::new())
        ;
    let res = client.get("https://www.jsonip.com/")
        .header("secret", "foo")
        .await
        .unwrap();
    // Note the default API (identical to reqwest) requires `await`ing the response body.
    let res = res.text().await.unwrap();
    
    let res = client.get("https://www.jsonip.com/")
        .header("secret", "foo")
        .send_awaiting_body()
        .await
        .unwrap();
    // By using `send_awaiting_body`, the response is loaded into memory, and we don't have to `await` it.
    let res = res.text().unwrap();
}

Roadmap

• Hide secrets in Recorder. Hash & Eq checks for requests must respect hidden values.
• Ensure it builds on wasm32-unknown-unknown
• Sanitize "sessid" in json
