Implementations

impl Signer

pub fn new(service: &str, region: &str) -> Self

Create a builder.

pub fn region(&self) -> &str

Get the region of this signer.

pub fn sign( &self, req: &mut impl SignableRequest, cred: &Credential, ) -> Result<()>

Example

use anyhow::Result;
use reqsign::AwsConfig;
use reqsign::AwsDefaultLoader;
use reqsign::AwsV4Signer;
use reqwest::Client;
use reqwest::Request;
use reqwest::Url;

#[tokio::main]
async fn main() -> Result<()> {
    let client = Client::new();
    let config = AwsConfig::default().from_profile().from_env();
    let loader = AwsDefaultLoader::new(client.clone(), config);
    let signer = AwsV4Signer::new("s3", "us-east-1");
    // 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
    let credential = loader.load().await?.unwrap();
    signer.sign(&mut req, &credential)?;
    // Sending already signed request.
    let resp = client.execute(req).await?;
    println!("resp got status: {}", resp.status());
    Ok(())
}

pub fn sign_query( &self, req: &mut impl SignableRequest, expire: Duration, cred: &Credential, ) -> Result<()>

Signing request with query.

Example

use std::time::Duration;

use anyhow::Result;
use reqsign::AwsConfig;
use reqsign::AwsDefaultLoader;
use reqsign::AwsV4Signer;
use reqwest::Client;
use reqwest::Request;
use reqwest::Url;

#[tokio::main]
async fn main() -> Result<()> {
    let client = Client::new();
    let config = AwsConfig::default().from_profile().from_env();
    let loader = AwsDefaultLoader::new(client.clone(), config);
    let signer = AwsV4Signer::new("s3", "us-east-1");
    // 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
    let credential = loader.load().await?.unwrap();
    signer.sign_query(&mut req, Duration::from_secs(3600), &credential)?;
    // Sending already signed request.
    let resp = client.execute(req).await?;
    println!("resp got status: {}", resp.status());
    Ok(())
}
