### Cómo funcionan los headers reenviados por el Proxy { #how-proxy-forwarded-headers-work }

Aquí tienes una representación visual de cómo el **proxy** añade headers reenviados entre el cliente y el **application server**:

```mermaid

```Python
say_hi()  # Ah, não, isso gera um erro! 😱
```

O parâmetro `name` continua obrigatório (não é opcional) porque não tem valor padrão. Ainda assim, `name` aceita `None` como valor:

```Python
say_hi(name=None)  # Isso funciona, None é válido 🎉
```

A boa notícia é que, na maioria dos casos, você poderá simplesmente usar `|` para definir uniões de tipos:

```python
def say_hi(name: str | None):
    print(f"Hey {name}!")
```

    assertThat(Adapters.parseGeneralizedTime("19920622123421Z"))
      .isEqualTo(date("1992-06-22T12:34:21.000+0000").time)
  }

  @Disabled("fractional seconds are not implemented")
  @Test
  fun `parse generalized time with fractional seconds`() {
    assertThat(Adapters.parseGeneralizedTime("19920722132100.3Z"))
      .isEqualTo(date("1992-07-22T13:21:00.300+0000").time)
  }

  // If true, use TFRT backend
  bool use_tfrt = false;
  // Whether to run elementary eager ops wrapped in a call op.
  bool run_eager_op_as_function = false;
  // Whether to rewrite jit_compile functions.
  bool jit_compile_rewrite = false;
};

`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare headers, you need to use `Header`, because otherwise the parameters would be interpreted as query parameters.

	// No network failure i.e response from the target means its up
	return true, nil
}

// Stat - returns lambda webhook target statistics such as
// current calls in progress, successfully completed functions
// failed functions.
func (target *WebhookTarget) Stat() event.TargetStat {
	return event.TargetStat{
		ID:             target.id,
		ActiveRequests: atomic.LoadInt64(&target.activeRequests),

    assertThrows(
        NullPointerException.class,
        () -> Multimaps.index((List<Integer>) values, Functions.identity()));
  }

  public void testIndex_nullKey() {
    List<Integer> values = Arrays.asList(1, 2);
    assertThrows(
        NullPointerException.class, () -> Multimaps.index(values, Functions.constant(null)));
  }

std::vector<string> GetFuncNames(const tensorflow::GraphDef& graph_def) {
  std::vector<string> names;
  auto functions = graph_def.library().function();
  names.reserve(functions.size());
  for (const tensorflow::FunctionDef& func : functions) {
    names.push_back(func.signature().name());
  }
  std::sort(names.begin(), names.end());
  return names;
}
