Hi Miguel~

Here's a demo code in this blog: https://blog.hiibolt.com/rust/axum/tokio/server/2024/01/10/MultipartRustServer.html#result

You can follow it to get the file data(bytes) and file name.
The blog shows that the file is in a multipart form data and named with fileupload.

If the http service is meant to accept untrusted user input, measures should likely also be taken to avoid overwriting existing files, and even more importantly to make sure that the file name does not contain a / or \ (normalizing it is generally a good idea).

Finally, std::io should not be used within async fn. Use tokios io (and fs) modules instead.

See the example here for robust overwrite protection.
