Здесь переменная `app` будет экземпляром класса `FastAPI`.

Это будет основная точка взаимодействия для создания всего вашего API.

### Шаг 3: создайте *операцию пути (path operation)* { #step-3-create-a-path-operation }

#### Путь (path) { #path }

Здесь «путь» — это последняя часть URL, начиная с первого символа `/`.

Итак, в таком URL:

```
https://example.com/items/foo
```

...путь будет:

	return nil
}

func getValidPath(path string) (string, error) {
	if path == "" {
		return path, errInvalidArgument
	}

	var err error
	// Disallow relative paths, figure out absolute paths.
	path, err = filepath.Abs(path)
	if err != nil {
		return path, err
	}

	fi, err := Lstat(path)
	if err != nil && !osIsNotExist(err) {
		return path, err
	}
	if osIsNotExist(err) {
