Você pode criar uma subclasse personalizada de `StreamingResponse` que define o cabeçalho `Content-Type` para o tipo de dado que você está transmitindo.

Por exemplo, você pode criar um `PNGStreamingResponse` que define o cabeçalho `Content-Type` como `image/png` usando o atributo `media_type`:

/**
 * Service provider interface for registering custom {@link Language} implementations.
 * <p>
 * This interface allows plugins and extensions to define and register additional programming languages

Ensuite, **FastAPI** appellera cette surcharge au lieu de la dépendance originale.

Vous pouvez définir une surcharge de dépendance pour une dépendance utilisée n’importe où dans votre application **FastAPI**.

 * Each entry is 4 bytes, and represents a _range_ of code points that all share a common 14-bit
 * prefix. Entries are sorted by their complete code points.
 *
 * The 4 bytes are named b0, b1, b2 and b3. We also define these supplemental values:
 *
 *  * **b2a**: b2 + 0x80
 *  * **b3a**: b3 + 0x80
 *  * **b2b3**: (b2 << 7) + b3

Você pode definir uma sobreposição de dependência para uma dependência que é utilizada em qualquer lugar da sua aplicação **FastAPI**.

[`HandshakeCertificates`][handshake_certificates] keeps the certificates for a TLS handshake.
Use its [builder][handshake_certificates_builder] to define which certificates the HTTPS server
returns to its clients. The returned instance can create an `SSLSocketFactory` that implements this
policy:

If you use any other tool to manage your installations, like `uv`, Poetry, Pipenv, or others, they all have a way that you can use to define specific versions for your packages.

## Available versions { #available-versions }

You can see the available versions (e.g. to check what is the current latest) in the [Release Notes](../release-notes.md).
