## Ejecuta el Programa del Servidor { #run-the-server-program }

Si instalaste un servidor ASGI manualmente, normalmente necesitarías pasar una cadena de import en un formato especial para que importe tu aplicación FastAPI:

<div class="termy">

```console
$ uvicorn main:app --host 0.0.0.0 --port 80

 * Fix: Persist proper `Content-Encoding` header to cache for GZip responses.
 * Fix: Eliminate rare race condition in SPDY streams that would prevent connection reuse.
 * Fix: Change HTTP date formats to UTC to conform to RFC2616 section 3.3.
 * Fix: Support SPDY header blocks with trailing bytes.
 * Fix: Allow `;` as separator for `Cache-Control` header.

        int maxReferralLevel = (int) maxReferralLevelField.get(trans2GetDfsReferral);

        // Then
        assertEquals(3, maxReferralLevel);
    }

    @Test
    @DisplayName("Test with various filename formats")
    void testVariousFilenameFormats() {
        // Test UNC path
        assertDoesNotThrow(() -> new Trans2GetDfsReferral(mockConfig, "\\\\server\\share"));

        // Test forward slashes

Uygulama başlamadan önce veya uygulama kapanırken çalıştırılması gereken event handler’ları (fonksiyonları) tanımlayabilirsiniz.

Bu fonksiyonlar `async def` ile veya normal `def` ile tanımlanabilir.

### `startup` eventi { #startup-event }

Uygulama başlamadan önce çalıştırılacak bir fonksiyon eklemek için, `"startup"` event’i ile tanımlayın:

 * {@code com.google.common.util.concurrent}) in degenerate class loaders which make certain
 * platform classes unavailable. Then we construct a test suite so we can run the normal
 * AbstractFutureTest test methods in these degenerate classloaders.

    int exponent = getExponent(x);
    if (!isNormal(x)) {
      return log2(x * IMPLICIT_BIT, mode) - SIGNIFICAND_BITS;
      // Do the calculation on a normal value.
    }
    // x is positive, finite, and normal
    boolean increment;
    switch (mode) {
      case UNNECESSARY:

      case FLOOR:

Keep in mind that the server (Uvicorn) won't use that `root_path` for anything else than passing it to the app.

But if you go with your browser to [http://127.0.0.1:8000/app](http://127.0.0.1:8000/app) you will see the normal response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

So, it won't expect to be accessed at `http://127.0.0.1:8000/api/v1/app`.

    * Önce router dependency’leri, sonra decorator’daki [`dependencies`](dependencies/dependencies-in-path-operation-decorators.md), sonra da normal parametre dependency’leri çalışır.
    * Ayrıca [`scopes` ile `Security` dependency’leri](../advanced/security/oauth2-scopes.md) de ekleyebilirsiniz.

/// tip | İpucu

Se você usa qualquer outra ferramenta para gerenciar suas instalações, como `uv`, Poetry, Pipenv ou outras, todas elas têm uma forma de definir versões específicas para seus pacotes.

## Versões disponíveis { #available-versions }

Você pode ver as versões disponíveis (por exemplo, para verificar qual é a mais recente) nas [Release Notes](../release-notes.md).

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation { #special-types-and-validation }

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.
