smithy-transport-reqwest

A small reqwest-backed implementation of aws_smithy_runtime_api::client::http::HttpClient.

use smithy_transport_reqwest::ReqwestHttpClient;

let http_client = ReqwestHttpClient::new();

The client caches reqwest connectors by smithy HTTP connector settings and applies smithy connect and read timeout values when creating the underlying reqwest clients. Reqwest's automatic redirect policy is disabled so generated smithy clients receive service responses directly.

TLS backend selection

Reqwest default features are disabled by this crate, and no TLS backend is enabled by default. Select the backend you want:

smithy-transport-reqwest = { version = "0.1", features = ["rustls"] }

Or, for native TLS:

smithy-transport-reqwest = { version = "0.1", features = ["native-tls"] }

Forwarded TLS features:

• rustls
• rustls-no-provider
• default-tls
• native-tls
• native-tls-no-alpn
• native-tls-vendored
• native-tls-vendored-no-alpn

Additional reqwest feature passthroughs are available for http2, http3, and system-proxy.

AWS SDK setup

Install this crate with a TLS feature, plus aws-config and whichever generated AWS SDK crates your application uses:

[dependencies]
aws-config = "1"
aws-sdk-s3 = "1"
smithy-transport-reqwest = { version = "0.1", features = ["rustls"] }

Then pass the HTTP client into the shared AWS config loader:

use aws_config::BehaviorVersion;
use smithy_transport_reqwest::ReqwestHttpClient;

# async fn example() {
let sdk_config = aws_config::defaults(BehaviorVersion::latest())
    .http_client(ReqwestHttpClient::new())
    .load()
    .await;

let s3 = aws_sdk_s3::Client::new(&sdk_config);
# let _ = s3;
# }
