How to force using http instead of https for s3 express operation?

[VoVAllen]

How can I modify the following code to force http?
Ref: #1091

use aws_config::BehaviorVersion;
use aws_sdk_s3::types::{
    BucketInfo, BucketType, CreateBucketConfiguration, DataRedundancy, LocationInfo, LocationType,
};
use aws_sdk_s3::Client;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let sdk_config = aws_config::load_defaults(BehaviorVersion::latest()).await;
    let client = Client::new(&sdk_config);

    let bucket_cfg = CreateBucketConfiguration::builder()
        .location(
            LocationInfo::builder()
                .name("usw2-az1")
                .r#type(LocationType::AvailabilityZone)
                .build(),
        )   
        .bucket(
            BucketInfo::builder()
                .data_redundancy(DataRedundancy::SingleAvailabilityZone)
                .r#type(BucketType::Directory)
                .build(),
        )   
        .build();

    // This name is just for an example purpose, use your own express bucket name
    let express_bucket = "s3express-example-bucket--usw2-az1--x-s3";

    let _ = client
        .create_bucket()
        .create_bucket_configuration(bucket_cfg)
        .bucket(express_bucket)
        .send()
        .await
        .expect("should create a directory bucket");
       
    // --snip--
    
    Ok(())
}

Hello! Reopening this discussion to make it searchable.

I have tried hitting an S3 express endpoint using AWS CLI to see if using HTTP is even supported.

With HTTPS

aws --endpoint-url https://s3express-usw2-az1.us-west-2.amazonaws.com s3api head-object --bucket my-test-bucket--usw2-az1--x-s3 --key foobar.txt

it works. However with HTTP

aws --endpoint-url http://s3express-usw2-az1.us-west-2.amazonaws.com s3api head-object --bucket my-test-bucket--usw2-az1--x-s3 --key foobar.txt

the command never comes back.

This leads me to believe use of HTTP with respect to S3 Express One Zone buckets is not supported. With that being said, what's your use case of forcing HTTP for S3 Express One Zone?

Sorry, what I mean is actually skip ssl verification to save cpu resource. I saw your issue and hope it can be included in the sdk soon!

But your example is hard to search, also not compatible with the latest rustls. Need to downgrade to an earlier version as you mentioned.
