And you could do this even if the data type in the request is not JSON.

For example, in this application we don't use FastAPI's integrated functionality to extract the JSON Schema from Pydantic models nor the automatic validation for JSON. In fact, we are declaring the request content type as YAML, not JSON:

{* ../../docs_src/path_operation_advanced_configuration/tutorial007_py310.py hl[15:20, 22] *}

		AES256GCM        = "AES-256-GCM-HMAC-SHA-256"
		CHACHA20POLY1305 = "ChaCha20Poly1305"
	)

	type JSON struct {
		Algorithm string `json:"aead"`
		ID        string `json:"id"`
		IV        []byte `json:"iv"`
		Nonce     []byte `json:"nonce"`
		Bytes     []byte `json:"bytes"`
	}
	var value JSON
	if err := json.Unmarshal(text, &value); err != nil {
		return ErrDecrypt
	}

```JSON
{
  "item": "The Foo Wrestlers"
}
```

但如果客户端请求 `http://example.com/items/bar`（不存在的 `item_id` `"bar"`），则会接收到 HTTP 状态码 404（“未找到”错误）及如下 JSON 响应结果：

```JSON
{
  "detail": "Item not found"
}
```

/// tip | 提示

触发 `HTTPException` 时，可以用参数 `detail` 传递任何能转换为 JSON 的值，不仅限于 `str`。

还支持传递 `dict`、`list` 等数据结构。
