Next, for an individual proxy we will check if it could possibly be impacted by the change. For example, we know a sidecar never is impacted by a `Gateway` update, and we can also look at scoping (from `Sidecar.egress.hosts`) to further restrict update scopes.

  for (i in namesAndValues.indices) {
    require(namesAndValues[i] != null) { "Headers cannot be null" }
    namesAndValues[i] = inputNamesAndValues[i].trim()
  }

  // Check for malformed headers.
  for (i in namesAndValues.indices step 2) {
    val name = namesAndValues[i]
    val value = namesAndValues[i + 1]
    headersCheckName(name)
    headersCheckValue(value, name)
  }

## Example

    ```Python hl_lines="9"
    {!> ../../../docs_src/query_params/tutorial002.py!}
    ```

Bu durumda, `q` fonksiyon parametresi isteğe bağlı olacak ve varsayılan değer olarak `None` alacaktır.

!!! check "Ek bilgi"
    Ayrıca, dikkatinizi çekerim ki; **FastAPI**, `item_id` parametresinin bir yol parametresi olduğunu ve `q` parametresinin yol değil bir sorgu parametresi olduğunu fark edecek kadar beceriklidir.

tf_cuda_library(
    name = "c_api_no_xla",

            if (containingFile == null || containingFile.declarations.firstOrNull() !is FirScript) {
                // Should be replaced with proper check after KT-61451 and KT-61887
                return false
            }
        }

        val firSymbol = symbol.firSymbol
        if (firSymbol is FirPropertySymbol && firSymbol.isForeignValue) {

      }
      currentThread.name = oldName
    }

  private fun afterRun(
    task: Task,
    delayNanos: Long,
  ) {
    lock.assertHeld()

    val queue = task.queue!!
    check(queue.activeTask === task)

    val cancelActiveTask = queue.cancelActiveTask
    queue.cancelActiveTask = false
    queue.activeTask = null
    busyQueues.remove(queue)

=== "Python 3.8+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/query_params/tutorial002.py!}
    ```

In diesem Fall wird der Funktionsparameter `q` optional, und standardmäßig `None` sein.

!!! check
    Beachten Sie auch, dass **FastAPI** intelligent genug ist, um zu erkennen, dass `item_id` ein Pfad-Parameter ist und `q` keiner, daher muss letzteres ein Query-Parameter sein.

## Query-Parameter Typkonvertierung

    ```

!!! info "Informação"
    Note que `response_description` se refere especificamente à resposta, a `description` se refere à *operação de rota* em geral.

!!! check
    OpenAPI especifica que cada *operação de rota* requer uma descrição de resposta.

    Então, se você não fornecer uma, o **FastAPI** irá gerar automaticamente uma de "Resposta bem-sucedida".
