Bunun nedeni, **OAuth2**’nin `username` ve `password` göndermek için "form data" kullanmasıdır.

///

Örneği şu şekilde çalıştırın:

<div class="termy">

```console
$ fastapi dev

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

    /**

     * identifier, artifact identifier, extension, classifier and version.

    default String getId() {

  static AtomicLong misses = new AtomicLong(0);

  @BeforeExperiment
  void setUp() {
    // random integers will be generated in this range, then raised to the
    // power of (1/concentration) and floor()ed
    max = Ints.checkedCast((long) Math.pow(distinctKeys, concentration));

    cache =
        CacheBuilder.newBuilder()
            .concurrencyLevel(segments)
            .maximumSize(maximumSize)

   * ("constant lists"). Example:
   *
   * {@snippet :
   * public static final ImmutableList<Color> GOOGLE_COLORS =
   *     new ImmutableList.Builder<Color>()
   *         .addAll(WEBSAFE_COLORS)
   *         .add(new Color(0, 191, 255))
   *         .build();
   * }
   *
   * <p>Elements appear in the resulting list in the same order they were added to the builder.

    assertThat(set.floor("f")).isNull();
  }

  public void testFloor_elementPresent() {
    ImmutableSortedSet<String> set =
        ImmutableSortedSet.copyOf(new String[] {"e", "a", "e", "f", "b", "i", "d", "a", "c", "k"});
    assertThat(set.floor("f")).isEqualTo("f");
    assertThat(set.floor("j")).isEqualTo("i");
    assertThat(set.floor("q")).isEqualTo("k");
  }

```

This is because **OAuth2** uses "form data" for sending the `username` and `password`.

///

Run the example with:

<div class="termy">

```console
$ fastapi dev

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

</div>

## Check it { #check-it }

Go to the interactive docs at: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Cela est dû au fait que **OAuth2** utilise des « form data » pour envoyer le `username` et le `password`.

///

Exécutez l'exemple avec :

<div class="termy">

```console
$ fastapi dev

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

</div>

## Vérifier { #check-it }

### Exécuter l'application { #run-the-app }

Vous pouvez exécuter l'application :

<div class="termy">

```console
$ fastapi dev

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

</div>

Das liegt daran, dass **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ fastapi dev

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