Stream file with multipart Form.

[silvestrpredko]

I am trying to stream a file to AWS s3.

  let m = zip.metadata().unwrap();
  // FramedRead::new(tokio::fs::File::from_std(zip), BytesCodec::new());
  // reqwest::Body::wrap_stream(FramedRead::new(tokio::fs::File::from_std(zip),
  // BytesCodec::new()));

  let form = Form::new()
      .text("key", fields.key.clone())
      .text("acl", fields.acl)
      .text("policy", fields.policy)
      .text("Content-Type", fields.content_type)
      .text("x-amz-algorithm", fields.x_amz_algorithm)
      .text("x-amz-credential", fields.x_amz_credential)
      .text("x-amz-date", fields.x_amz_date)
      .text("x-amz-security-token", fields.x_amz_security_token)
      .text("x-amz-signature", fields.x_amz_signature)
      .part(
          "file",
          Part::stream_with_length(
              reqwest::Body::wrap_stream(FramedRead::new(
                  tokio::fs::File::from_std(zip),
                  BytesCodec::new(),
              )),
              m.len(),
          )
          .file_name(fields.key),
      );

  client
      .post(url)
      .multipart(form)
      .send()
      .await?
      .error_for_status()?;

If I stream_with_length I receive an error => error.sources=[client error (SendRequest), user body write aborted, early end, expected 11470 more bytes]

If using a stream, then it complains that Content-Length is missing.

I wonder how properly I could move on without fully reading the file into memory and using Part::bytes.

I forgot to seek a file.
