# Código de status de resposta

Da mesma forma que você pode especificar um modelo de resposta, você também pode declarar o código de status HTTP usado para a resposta com o parâmetro `status_code` em qualquer uma das *operações de caminho*:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* etc.

## **FastAPI** utilities { #fastapi-utilities }

FastAPI provides several tools for each of these security schemes in the `fastapi.security` module that simplify using these security mechanisms.

In the next chapters you will see how to add security to your API using those tools provided by **FastAPI**.

### Go 1.24

Go 1.24 added a new `fips140` setting that controls whether the Go
Cryptographic Module operates in FIPS 140-3 mode.
The possible values are:
- "off": no special support for FIPS 140-3 mode. This is the default.
- "on": the Go Cryptographic Module operates in FIPS 140-3 mode.
- "only": like "on", but cryptographic algorithms not approved by
  FIPS 140-3 return an error or panic.

<summary>Was macht der Befehl <code>uvicorn main:app --reload</code> ...</summary>

Der Befehl `uvicorn main:app` bezieht sich auf:

* `main`: die Datei `main.py` (das Python-„Modul“).
* `app`: das Objekt, das innerhalb von `main.py` mit der Zeile `app = FastAPI()` erzeugt wurde.
* `--reload`: lässt den Server nach Codeänderungen neu starten. Tun Sie das nur während der Entwicklung.

    PathScope getPathScope();

    /**
     * Returns a filter for the types of path (class-path, module-path, …) accepted by the tool.
     * For example, if a Java tools accepts only class-path elements, then the filter should return
     * {@code true} for {@link JavaPathType#CLASSES} and {@code false} for {@link JavaPathType#MODULES}.
     * If no filter is explicitly set, then the default is a filter accepting everything.
     *

   * properties, including:
   *
   * <ul>
   *   <li>{@code java.vendor.version} (added in Java 11, listed as optional as of Java 13)
   *   <li>{@code jdk.module.*} (added in Java 9, optional)

Empecemos con una aplicación simple de FastAPI:

Nota que las *path operations* definen los modelos que usan para el payload de la petición y el payload del response, usando los modelos `Item` y `ResponseMessage`.
