Por exemplo, dentro de uma função de *operação de rota* `assíncrona`, você pode obter o conteúdo com:

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

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

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