Summary

This diff is large, but smaller parts make no sense without each other.

Introduced two entities:

  • HttpAuthenticatedService trait - to be implemented by services like ReportsService or BlobServiceClient. They do require either CSAM (UserIdentity) or a service-to-service token to work (e.g. make blob calls). But they can still be used in unauthenticated endpoints.
  • Authenticated<S> extractor. This is to be used in HTTP handler functions to get an instance of an aforementioned service - see D12508 for example usage.

The business logic code (FromRequest impl) was already implemented for Reports service. I extracted it into
the above trait and made more flexible. Added lots of in-code comments to better understand.

In the next diff, this will be implemented for Backup service - D12508.

Depends on D12506

Test Plan

Local reports service:

  • Upload report with valid CSAT - use it to get User ID and for blob service requests
  • Upload report with invalid CSAT - fallback to services-token
  • Upload report with no CSAT - service-to-service token was retrieved.

All reports were large enough to trigger Blob service uploads.

For Reports service, we use:

#[post("/")]
async fn post_reports(
  payload: web::Json<PostReportsPayload>,
  service: ReportsService,
) -> actix_web::Result<HttpResponse> {
  // ...
}

Left this trait here, to be able to use directly service: ReportsService instead of having to replace it with service: Authenticated<ReportsService>

But wondering if replacing it won't make the code simpler and more obvious than keeping this trait

This should be implemented by ReportsService, BlobServiceClient etc - see diff description

51 ↗(On Diff #41545)
94 ↗(On Diff #41545)

This is basically moved from impl FromRequest for ReportsService. Just made it more flexible

Overall looks good but might be good to get a review from someone with more experience in Rust (cc. @varun)

I think removing this trait makes sense
