# Parâmetros de path { #path-parameters }

Você pode declarar "parâmetros" ou "variáveis" de path com a mesma sintaxe usada por strings de formatação do Python:

{* ../../docs_src/path_params/tutorial001_py39.py hl[6:7] *}

O valor do parâmetro de path `item_id` será passado para a sua função como o argumento `item_id`.

# Dependencies - `Depends()` and `Security()`

## `Depends()`

Dependencies are handled mainly with the special function `Depends()` that takes a callable.

Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends

## `Security()`

    }

    @Test
    @DisplayName("createContext accepts null/empty optional parameters")
    void createContext_edge_parameters_ok() throws Exception {
        TestCredentials creds = new TestCredentials("D", false, false, new Subject(), false);
        // Intentionally pass null/empty values for optional parameters; expect no exception
        SSPContext ctx1 = creds.createContext(mockContext, null, "", null, false);
