現在，當瀏覽器建立一個帶有密碼的使用者時，API 會在回應中回傳相同的密碼。

在這個例子中可能不是問題，因為是同一個使用者送出該密碼。

但如果我們對其他「路徑操作」使用相同的模型，我們可能會把使用者密碼送給所有用戶端。

/// danger | 警告

除非你非常清楚所有影響並確定自己在做什麼，否則永遠不要儲存使用者的明文密碼，也不要像這樣在回應中傳送。

///

## 新增一個輸出模型 { #add-an-output-model }

我們可以改為建立一個包含明文密碼的輸入模型，以及一個不含密碼的輸出模型：

{* ../../docs_src/response_model/tutorial003_py310.py hl[9,11,16] *}

在這裡，雖然「路徑操作函式」回傳的是同一個包含密碼的輸入使用者：
