Can't set metadata when uplaoding file to S3

[benjaminjellis]

When trying to upload a file as follows, the meta data provided doesn't populate correctly when inspecting the object in the console.
I'd expect to see:

Type	Key	Value
System defined	Content-Type	image/jpeg
System defined	Content-Disposition	inline

but instead I see

Type	Key	Value
System defined	Content-Type	application/octet-stream
User defined	x-amz-meta-content-type	image/jpeg
User defined	x-amz-meta-content-disposition	inline

I've tried changing the keys in the hashmap for the metadata but to no avail, I can do this in other languages (e.g. python) just fine but I haven't figured out how to do this in rust. Any help would be greatly appreciated

let client: aws_sdk_s3::Client = some_client;
let data: Bytes = some_data;
let key = "some_key";
let bucket = "some_bucket";
let meta_data = HashMap::from([
            ("Content-Type".into(), "image/jpeg".into()),
            ("Content-Disposition".into(), "inline".into()),
        ]);
let resp = client
            .put_object()
            .bucket(bucket)
            .key(key)
            .body(data.into())
            .set_metadata(Some(meta_data))
            .send()
            .await
            .unwrap();

I think you need to set content_type directly instead of setting it via Metadata: https://docs.rs/aws-sdk-s3/latest/aws_sdk_s3/operation/put_object/builders/struct.PutObjectFluentBuilder.html#method.content_type (same for content_disposition

Let me know if that works.

Thanks Russell, I had missed that but it works as expected.
