#### Define a *path operation decorator* { #define-a-path-operation-decorator }

{* ../../docs_src/first_steps/tutorial001_py310.py hl[6] *}

The `@app.get("/")` tells **FastAPI** that the function right below is in charge of handling requests that go to:

* the path `/`
* using a <dfn title="an HTTP GET method"><code>get</code> operation</dfn>

/// info | `@decorator` Info

If synchronous replication is configured above, replication is attempted right away prior to returning the PUT object response. In the event that the replication target is down, the `X-Amz-Replication-Status` is marked as `FAILED` and resynced with target when the scanner runs again.

            if (response != null) {
                response.clearReceived();
            }

            // try TreeConnectAndX with the request
            // this does not make any sense if we are disconnecting right now
            T chainedResponse = null;
            if (!(request instanceof SmbComTreeDisconnect) && !(request instanceof Smb2TreeDisconnectRequest)) {
                chainedResponse = treeConnect(request, response);

constraints.AssertTrue.message = {item} deve ser verdadeiro.
constraints.DecimalMax.message = {item} deve ser menor que {value}.
constraints.DecimalMin.message = {item} deve ser maior que {value}.
constraints.Digits.message = {item} deve ser um número. (Esperado: <número>.<número>)
constraints.Future.message = {item} deve ser uma data futura.
constraints.Max.message = {item} deve ser menor ou igual a {value}.

	if match, err := regexp.MatchString("^\"[^\"]+\"$", name); err != nil {
		return err
	} else if match {
		return nil
	}

	// normalize the name to letters, digits, _ or $
	valid := true
	cleaned := strings.Map(func(r rune) rune {
		switch {
		case unicode.IsLetter(r):
			return 'a'
		case unicode.IsDigit(r):
			return '0'
		case r == '_', r == '$':
			return r

constraints.AssertTrue.message = {item} harus bernilai true.
constraints.DecimalMax.message = {item} harus kurang dari {value}.
constraints.DecimalMin.message = {item} harus lebih dari {value}.
constraints.Digits.message = {item} harus berupa angka. (expected: <number>.<number>)
constraints.Future.message = {item} harus berupa nilai masa depan.
constraints.Max.message = {item} harus kurang dari atau sama dengan {value}.

Es spielt keine Rolle. **FastAPI** weiß, was zu tun ist.

/// note | Hinweis

Wenn Ihnen das nichts sagt, lesen Sie den [Async: *„In Eile?“*](../../async.md#in-a-hurry)-Abschnitt über `async` und `await` in der Dokumentation.

///

## Integriert in OpenAPI { #integrated-with-openapi }

The code following the `yield` statement is executed after the response:

{* ../../docs_src/dependencies/tutorial007_py310.py hl[5:6] *}

/// tip

You can use `async` or regular functions.

**FastAPI** will do the right thing with each, the same as with normal dependencies.
