Se você utiliza uma versão anterior, ocorrerão erros ao tentar utilizar `Annotated`.

Certifique-se de [Atualizar a versão do FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions) para pelo menos 0.95.1 antes de usar `Annotated`.

With this setting, requests without a `Content-Type` header will have their body parsed as JSON, which is the same behavior as older versions of FastAPI.

This behavior and configuration was added in FastAPI 0.132.0.

The most common way to do it is to have a file `requirements.txt` with the package names and their versions, one per line.

You would of course use the same ideas you read in [About FastAPI versions](versions.md) to set the ranges of versions.

For example, your `requirements.txt` could look like:

```
fastapi[standard]>=0.113.0,<0.114.0
pydantic>=2.7.0,<3.0.0
```

                    <la:hidden property="id"/>
                    <la:hidden property="versionNo"/>
                </c:if>
                <la:hidden property="createdBy"/>
                <la:hidden property="createdTime"/>
