reqsign  

Signing API requests without effort.

---

Most API is simple. But they could be complicated when they are hidden from complex abstraction. reqsign bring the simple API back: build, sign, send.

Quick Start

use anyhow::Result;
use reqsign::AwsConfig;
use reqsign::AwsLoader;
use reqsign::AwsV4Signer;
use reqwest::Client;

#[tokio::main]
async fn main() -> Result<()> {
    // Signer can load region and credentials from environment by default.
    let client = Client::new();
    let config = AwsConfig::default().from_profile().from_env();
    let loader = AwsLoader::new(client.clone(), config);
    let signer = AwsV4Signer::new("s3", "us-east-1");
    // Construct http::Request, and convert it into parts and body
    let req = http::Request::get("https://s3.amazonaws.com/testbucket").body(reqwest::Body::from(""))?;
    let (mut parts, body) = req.into_parts();
    // Signing request with Signer, and convert it back to reqwest::Request
    let credential = loader.load().await?.unwrap();
    signer.sign(&mut parts, &credential)?;
    let req = http::Request::from_parts(parts, body).try_into()?;
    // Sending already signed request.
    let resp = client.execute(req).await?;
    println!("resp got status: {}", resp.status());
    Ok(())
}
