## Escreva o código de documentação do callback { #write-the-callback-documentation-code }

Esse código não será executado em seu aplicativo, nós só precisamos dele para *documentar* como essa *API externa* deveria ser.

Mas, você já sabe como criar facilmente documentação automática para uma API com o **FastAPI**.

			}
			f.ServeHTTP(w, r)
		case <-r.Context().Done():
			globalHTTPStats.addRequestsInQueue(-1)
			// When the client disconnects before getting the S3 handler
			// status code response, set the status code to 499 so this request
			// will be properly audited and traced.
			w.WriteHeader(499)
		default:
			globalHTTPStats.addRequestsInQueue(-1)
			if contextCanceled(ctx) {
				w.WriteHeader(499)
				return

			// Expect header is always of form:
			//
			//   Expect       =  "Expect" ":" 1#expectation
			//   expectation  =  "100-continue" | expectation-extension
			//
			// So it safe to assume that '100-continue' is what would
			// be sent, for the time being keep this work around.
			// Adding a *TODO* to remove this later when Golang server
			// doesn't filter out the 'Expect' header.

Handlers have a predefined Handler ID.
In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

Handlers should remain backwards compatible. If a breaking API change is required, a new handler ID should be created.

## Setup & Configuration

		// Indicate we are ready to write.
		doneCh <- err

		// Wait for channel to be closed so we don't race on writes.

		// Clear so we can be called multiple times without crashing.
		doneCh = nil
	}, &closeNotifier{rc: r.Body, done: bodyDoneCh}
}

// keepHTTPResponseAlive can be used to avoid timeouts with long storage

* **ReDoc**: bereitgestellt unter `/redoc`.
    * Sie können deren URL mit dem Parameter `redoc_url` festlegen.
    * Sie können sie deaktivieren, indem Sie `redoc_url=None` festlegen.

Um beispielsweise Swagger UI so einzustellen, dass sie unter `/documentation` bereitgestellt wird, und ReDoc zu deaktivieren:

enabling the HTTP/2 use by the HTTP client broke programs
connecting to servers with buggy HTTP/2 implementations.
These kinds of changes are unavoidable and
[permitted by the Go 1 compatibility rules](/doc/go1compat).
Even so, Go provides a mechanism called GODEBUG to
reduce the impact such changes have on Go developers
using newer toolchains to compile old code.

A GODEBUG setting is a `key=value` pair
