### Bir *Yol Parametresi* Tanımlayalım

Sonrasında, yarattığımız enum sınıfını (`ModelName`) kullanarak tip belirteci aracılığıyla bir *yol parametresi* oluşturalım:

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### Dokümana Göz Atalım

///

### 声明*路径参数*

使用 Enum 类（`ModelName`）创建使用类型注解的*路径参数*：

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### 查看文档

 API 文档会显示预定义*路径参数*的可用值：

<img src="/img/tutorial/path-params/image03.png">

### 使用 Python _枚举类型_

*路径参数*的值是枚举的元素。

#### 比较*枚举元素*

枚举类 `ModelName` 中的*枚举元素*支持比较操作：

```Python hl_lines="17"

- Kube-controller-manager: the dynamic resource controller steps in when a pod got created such that the scheduler ignores it (i.e. spec.nodeName is set) and then takes care of triggering delayed resource claim allocation and/or reserving a claim for the pod. ([#118209](https://github.com/kubernetes/kubernetes/pull/118209), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth,...

			gotPodName, gotNamespace := InferPodInfo(tt.proxyName, tt.namespace)
			if gotPodName != tt.wantPodName || gotNamespace != tt.wantNamespace {
				t.Errorf("unexpected podName and namespace: wanted %v %v got %v %v", tt.wantPodName, tt.wantNamespace, gotPodName, gotNamespace)
			}
		})
	}
}

func TestInferPodInfoFromTypedResource(t *testing.T) {
	tests := []struct {

// limitations under the License.

package plugin

// InterceptRuleMgr configures networking tables (e.g. iptables or nftables) for
// redirecting traffic to an Istio proxy.
type InterceptRuleMgr interface {
	Program(podName, netns string, redirect *Redirect) error
}

// Constructor for iptables InterceptRuleMgr
func IptablesInterceptRuleMgr() InterceptRuleMgr {
	return newIPTables()

### Déclarer un paramètre de chemin

Créez ensuite un *paramètre de chemin* avec une annotation de type désignant l'énumération créée précédemment (`ModelName`) :

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### Documentation

### Declare um *parâmetro de rota*

Logo, crie um *parâmetro de rota* com anotações de tipo usando a classe enum que você criou (`ModelName`):

```Python hl_lines="16"
{!../../docs_src/path_params/tutorial005.py!}
```

### Revise a documentação

- Scheduler bugfix: Scheduler doesn't lose pod information when nodes are quickly recreated. This could happen when nodes are restarted or quickly recreated reusing a nodename. ([#93964](https://github.com/kubernetes/kubernetes/pull/93964), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling and Testing]

  qualified domain name (FQDN) of a Pod is set as hostname of its containers. 
  In Linux containers, this means setting the FQDN in the hostname field of the 
  kernel (the nodename field of struct utsname).  In Windows containers, this
  means setting the this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters to FQDN. 

#### *列挙型メンバ*の比較

これは、作成した列挙型 `ModelName` の*列挙型メンバ*と比較できます:

```Python hl_lines="17"
{!../../docs_src/path_params/tutorial005.py!}
```

#### *列挙値*の取得

`model_name.value` 、もしくは一般に、 `your_enum_member.value` を使用して実際の値 (この場合は `str`) を取得できます。

```Python hl_lines="20"
{!../../docs_src/path_params/tutorial005.py!}
```

/// tip | "豆知識"

`ModelName.lenet.value` でも `"lenet"` 値にアクセスできます。
