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.

use reqsign::AwsV4Signer;
use reqwest::{Client, Request, Url};
use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()>{
    // Signer will load region and credentials from environment by default.
    let signer = AwsV4Signer::builder().service("s3").build()?;
    // Construct request
    let url = Url::parse("https://s3.amazonaws.com/testbucket")?;
    let mut req = reqwest::Request::new(http::Method::GET, url);

    // Signing request with Signer
    signer.sign(&mut req)?;

    // Sending already signed request.
    let resp = Client::new().execute(req).await?;
    println!("resp got status: {}", resp.status());
    Ok(())
}
