```JSON

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.

    * 也會被自動用戶端程式碼產生工具使用。
* 使用 Pydantic 將回傳資料**序列化**為 JSON，而 Pydantic 是用 **Rust** 撰寫的，因此會 **更快很多**。

但更重要的是：

* 它會將輸出資料限制並過濾為回傳型別中定義的內容。
    * 這對安全性特別重要，下面會再看到更多細節。

## `response_model` 參數 { #response-model-parameter }

有些情況下，你需要或想要回傳的資料與你宣告的型別不完全相同。

例如，你可能想要回傳一個 dictionary 或資料庫物件，但把回應宣告為一個 Pydantic 模型。這樣 Pydantic 模型就會替你回傳的物件（例如 dictionary 或資料庫物件）處理所有的資料文件、驗證等。

如果你加了回傳型別註解，工具與編輯器會（正確地）抱怨你的函式回傳的型別（例如 dict）與你宣告的（例如 Pydantic 模型）不同。

# 路徑參數 { #path-parameters }

你可以用與 Python 格式化字串相同的語法來宣告路徑「參數」或「變數」：

{* ../../docs_src/path_params/tutorial001_py310.py hl[6:7] *}

路徑參數 `item_id` 的值會作為引數 `item_id` 傳入你的函式。

所以，如果你執行這個範例並前往 [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo)，你會看到這樣的回應：

```JSON
{"item_id":"foo"}
```

## 具型別的路徑參數 { #path-parameters-with-types }

你可以在函式中使用標準的 Python 型別註記為路徑參數宣告型別：

Refer the [Values file](./values.yaml) for all the possible config fields. You can specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example, ```bash helm install --name my-release --set persistence.size=1Ti minio/minio ``` The above command deploys MinIO server with a 1Ti backing persistent volume. Alternately, you can provide a YAML file that specifies parameter values while installing the chart. For example, ```bash helm install --name my-release -f values.yaml...
