How to hook into raw network traffic?

[rosscanning]

For testing & debugging purposes, I need to be able to monitor the raw bytes: the serialized request that leaves, and the incoming response before it is deserialized. Is this currently possible? If not, can you point me to where in the code I should look - i.e., where in the code are requests serialized, and responses deserialized?

Thanks for any help (the SDK is awesome, BTW!)

There are a couple of ways. If you just want to see it, you can enable trace logging of the aws_smithy_http crate.

tracing_subscriber::fmt::init(); // tracing-subscriber = { version = "0.3", features = ["env-filter"] }

RUST_LOG=aws_smithy_http=trace cargo run

If you need to actually capture it, I'd suggest building something a connection that captures traffic as it runs. We have a few in the SDK already, the most sophisticated being dvr. You can then use this custom connection when constructing a client with from_conf_conn. You can see an example of doing this here.
