// implementation because:
      // 1. the string constructor can avoid an extra copy most of the time by correctly sizing the
      //    internal char array (hard to avoid using StringBuilder)
      // 2. we avoid extra copies into temporary buffers altogether
      // The downside is that this will cause us to store the file bytes in memory twice for a short

你大概已看過如何為*路徑操作*宣告 `response_model` 與 `status_code`。

這會定義該*路徑操作*主要回應的中繼資料。

你也可以宣告額外的回應及其模型、狀態碼等。

文件中有完整章節說明，請見 [OpenAPI 中的額外回應](additional-responses.md)。

## OpenAPI 額外資訊 { #openapi-extra }

當你在應用程式中宣告一個*路徑操作*時，FastAPI 會自動產生該*路徑操作*的相關中繼資料，並納入 OpenAPI 結構中。

/// note | 技術細節

在 OpenAPI 規格中，這稱為 [Operation 物件](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object)。

== Building with extra plugins
Additional plugins may be built alongside elasticsearch, where their
dependency on elasticsearch will be substituted with the local elasticsearch
build. To add your plugin, create a directory called elasticsearch-extra as
a sibling of elasticsearch. Checkout your plugin underneath elasticsearch-extra
and the build will automatically pick it up. You can verify the plugin is
