* 在返回模板的*路径操作*中声明 `Request` 参数
* 使用 `templates` 渲染并返回 `TemplateResponse`，传递模板的名称、request 对象以及一个包含多个键值对（用于 Jinja2 模板）的 "context" 字典。

/// note | 注意

在 FastAPI 0.108.0，Starlette 0.29.0 之前，`name` 是第一个参数。
并且，在此之前，`request` 对象是作为 context 的一部分以键值对的形式传递的。

///

/// tip | 提示

通过声明 `response_class=HTMLResponse`，API 文档就能识别响应的对象是 HTML。

接著你可以在 `templates/item.html` 編寫模板，例如：

```jinja hl_lines="7"
{!../../docs_src/templates/templates/item.html!}
```

### 模板 context 值 { #template-context-values }

在包含以下內容的 HTML 中：

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...它會顯示你在傳入的 context `dict` 中提供的 `id`：

```Python
{"id": id}
```

例如，若 ID 為 `42`，會渲染為：

```html
Item ID: 42
```

		buffer := make([]byte, len(data), 2*len(data))
		copy(buffer, data)

		erasure, err := NewErasure(t.Context(), test.dataBlocks, test.parityBlocks, blockSizeV2)
		if err != nil {
			t.Fatalf("Test %d: failed to create erasure: %v", i, err)
		}
		encoded, err := erasure.EncodeData(t.Context(), buffer)
		if err != nil {
			t.Fatalf("Test %d: failed to encode data: %v", i, err)
		}

		Message:    "Cannot use reserved tier name",
		StatusCode: http.StatusBadRequest,
	}
)

func (api adminAPIHandlers) AddTierHandler(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()

	objAPI, cred := validateAdminReq(ctx, w, r, policy.SetTierAction)
	if objAPI == nil {
		return
	}

	password := cred.SecretKey

```jinja hl_lines="7"

```

### Valores de Contexto de la Plantilla { #template-context-values }

En el HTML que contiene:

{% raw %}

```jinja
Item ID: {{ id }}
```

{% endraw %}

...mostrará el `id` tomado del `dict` de "contexto" que pasaste:

```Python
{"id": id}
```

Por ejemplo, con un ID de `42`, esto se renderizaría como:
