Grâce à cela, **FastAPI** fournit lui-même une documentation d'API alternative (utilisant ReDoc), accessible sur [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) :

De la même façon, il existe de nombreux outils compatibles, y compris des outils de génération de code pour de nombreux langages.

     * @param parentLeaseKey the parent lease key (can be null)
     * @param epoch the lease epoch
     */
    public void addLeaseV2Context(Smb2LeaseKey leaseKey, int requestedState, Smb2LeaseKey parentLeaseKey, int epoch) {
        LeaseV2CreateContextRequest leaseContext = new LeaseV2CreateContextRequest(leaseKey, requestedState, parentLeaseKey, epoch);
        addCreateContext(leaseContext);

## 使用单文件 FastAPI 构建 Docker 镜像 { #build-a-docker-image-with-a-single-file-fastapi }

    assertThat(builder["e"]).isNull()
  }

  @Test fun builderSetOperator() {
    val builder = Headers.Builder()
    builder["a"] = "b"
    builder["c"] = "d"
    builder["e"] = Date(0L)
    builder["g"] = Instant.EPOCH
    assertThat(builder["a"]).isEqualTo("b")
    assertThat(builder["c"]).isEqualTo("d")
    assertThat(builder["e"]).isEqualTo("Thu, 01 Jan 1970 00:00:00 GMT")

После этого, если перейти по адресам `/openapi.json`, `/docs` или `/redoc`, вы получите ошибку `404 Not Found`, например:

```JSON
{
    "detail": "Not Found"
}

     */
    @Size(max = 1000)
    public String updatedBy;

    /**
     * The timestamp when this role was last updated.
     * Stored as a long value representing milliseconds since epoch.
     * Used for audit trail and concurrency control.
     */
    @ValidateTypeFailure
    public Long updatedTime;

    /**
     * The version number of the role for optimistic locking.

     */
    @Size(max = 1000)
    public String updatedBy;

    /**
     * The timestamp when this label type was last updated.
     * Stored as a long value representing milliseconds since epoch.

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Luego, si vas a las URLs en `/openapi.json`, `/docs`, o `/redoc`, solo obtendrás un error `404 Not Found` como:

```JSON
{
    "detail": "Not Found"
}

$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Wenn Sie dann zu den URLs unter `/openapi.json`, `/docs` oder `/redoc` gehen, erhalten Sie lediglich einen `404 Not Found`-Fehler, wie:

```JSON
{
    "detail": "Not Found"
}

$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Ensuite, si vous allez aux URL `/openapi.json`, `/docs` ou `/redoc`, vous obtiendrez simplement une erreur `404 Not Found` comme :

```JSON
{
    "detail": "Not Found"
}
