## Basit ve Güçlü { #simple-and-powerful }

Hiyerarşik dependency injection sistemi tanımlamak ve kullanmak çok basit olsa da, hâlâ oldukça güçlüdür.

## 模型的清單 { #list-of-models }

同樣地，你可以將回應宣告為物件的 `list`。

為此，使用標準的 Python `list`：

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## 以任意 `dict` 作為回應 { #response-with-arbitrary-dict }

你也可以用一般的任意 `dict` 宣告回應，只需指定鍵和值的型別，而不必使用 Pydantic 模型。

當你事先不知道可用的欄位／屬性名稱（定義 Pydantic 模型所需）時，這很實用。

此時可使用 `dict`：

{* ../../docs_src/extra_models/tutorial005_py310.py hl[6] *}

./mc cp /tmp/data/defpartsize minio1/test-bucket/defpartsize --enc-c "minio1/test-bucket/defpartsize=${TEST_MINIO_ENC_KEY}" --insecure

# DISABLED: We must check the response header to see if compression was actually applied
#RESULT=$({ ./mc put /tmp/data/mpartobj.txt minio1/test-bucket/mpartobj.txt --enc-c "minio1/test-bucket/mpartobj.txt=${TEST_MINIO_ENC_KEY}" --insecure; } 2>&1)

「代理」會攔截原始用戶端請求，並在將其轉交給「應用伺服器」之前加入特殊的「轉發」標頭（`X-Forwarded-*`）。

這些標頭會保留原始請求中原本會遺失的資訊：

* X-Forwarded-For：原始用戶端的 IP 位址
* X-Forwarded-Proto：原始協定（`https`）

		t.Fatalf("Initializing config.json failed")
	}

	objectName := `\../.minio.sys/config/hello.txt`

	// initialize HTTP NewRecorder, this records any mutations to response writer inside the handler.
	rec := httptest.NewRecorder()
	// construct HTTP request for Get Object end point.
	req, err := newTestSignedRequestV4(http.MethodPut, getPutObjectURL("", bucketName, objectName),

  }

  /**
   * A predicate that is expected to return true subsequent to finalization, that is, one
   * of the following actions taken by the garbage collector when performing a full collection in
   * response to {@link System#gc()}:
   *
   * <ul>
   *   <li>invoking the {@code finalize} methods of unreachable objects
   *   <li>clearing weak references to unreachable referents

在介绍依赖项与安全的章节中，你可以更直观地看到用 `raise` 异常代替 `return` 值的优势。

本例中，客户端用不存在的 `ID` 请求 `item` 时，触发状态码为 `404` 的异常：

{* ../../docs_src/handling_errors/tutorial001_py310.py hl[11] *}

### 响应结果 { #the-resulting-response }

请求为 `http://example.com/items/foo`（`item_id` 为 `"foo"`）时，客户端会接收到 HTTP 状态码 200 及如下 JSON 响应结果：

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

		FileList: handler,

O LLM provavelmente vai traduzir isso errado. O interessante é apenas se ele mantém a tradução corrigida ao retraduzir.

**代理**会拦截原始客户端请求，并在将请求传递给**应用服务器**之前，添加特殊的*转发*请求头（`X-Forwarded-*`）。

这些请求头保留了原始请求中否则会丢失的信息：

- X-Forwarded-For：原始客户端的 IP 地址
- X-Forwarded-Proto：原始协议（`https`）
