## Prerequisites

Por exemplo, dentro de uma *função de operação de rota* assíncrona você pode obter os conteúdos com:

```Python
contents = await myfile.read()
```

Se você estiver dentro de uma *função de operação de rota* definida normalmente com `def`, você pode acessar `UploadFile.file` diretamente, por exemplo:

```Python
contents = myfile.file.read()
```

	Porque estamos usando uma URL relativa, se sua API estava localizada em `https://example.com/`, então irá referir-se à `https://example.com/token`. Mas se sua API estava localizada em `https://example.com/api/v1/`, então irá referir-se à `https://example.com/api/v1/token`.
