A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

As part of the application object creation, a *path operation* for `/openapi.json` (or for whatever you set your `openapi_url`) is registered.

It just returns a JSON response with the result of the application's `.openapi()` method.

Aber für den generierten Client könnten wir die OpenAPI-Operation-IDs direkt vor der Generierung der Clients **modifizieren**, um diese Methodennamen schöner und **sauberer** zu machen.

Wir könnten das OpenAPI-JSON in eine Datei `openapi.json` herunterladen und dann mit einem Skript wie dem folgenden **den präfixierten Tag entfernen**:

有些情況你可能需要修改自動產生的 OpenAPI 結構（schema）。

本章將示範如何做。

## 一般流程 { #the-normal-process }

一般（預設）的流程如下。

`FastAPI` 應用程式（實例）有一個 `.openapi()` 方法，會回傳 OpenAPI 結構。

在建立應用物件時，會同時註冊一個 `/openapi.json`（或你在 `openapi_url` 設定的路徑）的路徑操作（path operation）。

這個路徑只會回傳一個 JSON 回應，內容就是應用的 `.openapi()` 方法結果。

預設情況下，`.openapi()` 會先檢查 `.openapi_schema` 屬性是否已有內容，有的話就直接回傳。

若沒有，則會呼叫 `fastapi.openapi.utils.get_openapi` 這個工具函式來產生。

`get_openapi()` 函式會接收以下參數：

	return w.streamErr
}

type metacacheBlock struct {
	data  []byte
	n     int
	First string `json:"f"`
	Last  string `json:"l"`
	EOS   bool   `json:"eos,omitempty"`
}

func (b metacacheBlock) headerKV() map[string]string {
	json := jsoniter.ConfigCompatibleWithStandardLibrary
	v, err := json.Marshal(b)
	if err != nil {
		bugLogIf(context.Background(), err) // Unlikely
		return nil
	}

                    show it as the response (JSON Schema).
                * Serialization: you could return an arbitrary object and the
                    `response_model` would be used to serialize that object into the
                    corresponding JSON.
                * Filtering: the JSON sent to the client will only contain the data
