#### The time to answer helps the attackers { #the-time-to-answer-helps-the-attackers }

At that point, by noticing that the server took some microseconds longer to send the "Incorrect username or password" response, the attackers will know that they got _something_ right, some of the initial letters were right.

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

Pode até ser um Stream infinito, em que você continua enviando dados.

## JSON Lines { #json-lines }

Nesses casos, é comum enviar "**JSON Lines**", um formato em que você envia um objeto JSON por linha.

Uma response teria um tipo de conteúdo `application/jsonl` (em vez de `application/json`) e o corpo seria algo como:

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}

            });
        });
        if (!list.isEmpty()) {
            list.forEach(jobLog -> {
                jobLog.setJobStatus(Constants.FAIL);
                jobLog.setScriptResult("No response from Job.");
                jobLog.setEndTime(ComponentUtil.getSystemHelper().getCurrentTimeAsLong());
            });
            jobLogBhv.batchUpdate(list);
        }
    }

    /**

## JSON Lines { #json-lines }

In diesen Fällen ist es üblich, „JSON Lines“ zu senden, das ist ein Format, bei dem Sie pro Zeile genau ein JSON-Objekt senden.

Eine Response hätte einen Content-Type von `application/jsonl` (anstelle von `application/json`) und der Body sähe etwa so aus:

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}

{* ../../docs_src/custom_request_and_route/tutorial003_py310.py hl[26] *}

Dans cet exemple, les *chemins d'accès* sous le `router` utiliseront la classe personnalisée `TimedRoute`, et auront un en-tête supplémentaire `X-Response-Time` dans la réponse avec le temps nécessaire pour générer la réponse :

/// info

請記得，dataclass 無法做到 Pydantic 模型能做的一切。

所以你可能仍然需要使用 Pydantic 模型。

但如果你手邊剛好有一堆 dataclass，這是個不錯的小技巧，可以用來用 FastAPI 驅動一個 Web API。🤓

///

## 在 `response_model` 中使用 Dataclasses { #dataclasses-in-response-model }

你也可以在 `response_model` 參數中使用 `dataclasses`：

{* ../../docs_src/dataclasses_/tutorial002_py310.py hl[1,6:12,18] *}

該 dataclass 會自動轉換為 Pydantic 的 dataclass。

如此一來，其結構描述（schema）會顯示在 API 文件介面中：

			return
		}
		received = string(b)
		if received != "message two\n" {
			t.Errorf(`server: expected: "message two\n", got: %v`, received)
			return
		}

		// Send a response.
		_, terr = io.WriteString(deadlineconn, "messages received\n")
		if terr != nil {
			t.Errorf("failed to write to client. %v", terr)
			return
		}
	}()

	c, err := net.Dial("tcp", serverAddr)

If synchronous replication is configured above, replication is attempted right away prior to returning the PUT object response. In the event that the replication target is down, the `X-Amz-Replication-Status` is marked as `FAILED` and resynced with target when the scanner runs again.
