  Currently, the expression evaluator used to resolve configuration values
  is the DefaultExpressionEvaluator, which is a local variable within the
  implementation of the BasicComponentConfigurator. This ExpressionEvaluator
  simply returns the expression itself as the resolved value, which adds
  very little value to the container. Things like ${project.build.resources}
  are not resolved, and result in a type mismatch for the member injection.

            assertEquals("file.txt", loc.getName());
            assertEquals("smb://server/share/path/", loc.getParent());
            assertEquals(url, loc.getPath());
            // canonicalisation simply removes '.' and '..'
            assertEquals("smb://server/share/path/filetxt", loc.getCanonicalURL());
            assertFalse(loc.isRoot());
        }

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

Mas, o FastAPI (na verdade, o Starlette) fornece uma maneira mais simples de fazer isso que garante que os middlewares internos lidem com erros do servidor e que os manipuladores de exceções personalizados funcionem corretamente.

Para isso, você usa `app.add_middleware()` (como no exemplo para CORS).

In some cases, you might still have to use Pydantic's version of `dataclasses`. For example, if you have errors with the automatically generated API documentation.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

{* ../../docs_src/dataclasses_/tutorial003_py310.py hl[1,4,7:10,13:16,22:24,27] *}

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares handle server errors and custom exception handlers work properly.

For that, you use `app.add_middleware()` (as in the example for CORS).
