Kurz gefasst:

* `100 - 199` stehen für „Information“. Sie verwenden diese selten direkt. Responses mit diesen Statuscodes dürfen keinen Body haben.
* **`200 - 299`** stehen für „Successful“-Responses („Erfolgreich“). Diese werden Sie am häufigsten verwenden.
    * `200` ist der Default-Statuscode, was bedeutet, alles ist „OK“.

/// info | 資訊

請注意，`response_description` 專指回應，而 `description` 則是針對整個「路徑操作」的一般描述。

///

/// check | 檢查

OpenAPI 規範要求每個「路徑操作」都必須有一個回應描述。

因此，如果你未提供，**FastAPI** 會自動產生 "Successful response"。

## 將「路徑操作」標記為已棄用 { #deprecate-a-path-operation }

若需要將「路徑操作」標記為 <dfn title="已過時，建議不要再使用">已棄用</dfn>，但不移除它，請傳入參數 `deprecated`：
