 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"
{!../../docs_src/path_params/tutorial005.py!}
```

#### 获取*枚举值*

使用 `model_name.value` 或 `your_enum_member.value` 获取实际的值（本例中为**字符串**）：

```Python hl_lines="20"

        return false;
      }
      if (aspect2 != other.aspect2) {
        return false;
      }
      return true;
    }

    @Override
    public int hashCode() {
      int result = 17;
      result = 37 * result + aspect1;
      result = 37 * result + aspect2;
      return result;
    }
  }

  /** Test class with invalid hashCode method. */
  private static class InvalidHashCodeObject {

#### *Enumeration Üyelerini* Karşılaştıralım

Parametreyi, yarattığınız enum olan `ModelName` içerisindeki *enumeration üyesi* ile karşılaştırabilirsiniz:

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

#### *Enumeration Değerini* Edinelim

しかし、追加のボディパラメータを宣言したときのように、キー `item` を持つ JSON とその中のモデルの内容を期待したい場合は、特別な `Body` パラメータ `embed` を使うことができます:

```Python
item: Item = Body(..., embed=True)
```

以下において:

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

この場合、**FastAPI** は以下のようなボディを期待します:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",

The value of the *path parameter* will be an *enumeration member*.

#### Compare *enumeration members*

You can compare it with the *enumeration member* in your created enum `ModelName`:

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

#### Get the *enumeration value*

You can get the actual value (a `str` in this case) using `model_name.value`, or in general, `your_enum_member.value`:

El valor del *parámetro de path* será un *enumeration member*.

#### Compara *enumeration members*

Puedes compararlo con el *enumeration member* en el enum (`ModelName`) que creaste:

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

#### Obtén el *enumeration value*

Puedes obtener el valor exacto (un `str` en este caso) usando `model_name.value`, o en general, `your_enum_member.value`:

pkg debug/elf, const R_390_JMP_SLOT R_390
pkg debug/elf, const R_390_NONE = 0
pkg debug/elf, const R_390_NONE R_390
pkg debug/elf, const R_390_PC16 = 16
pkg debug/elf, const R_390_PC16 R_390
pkg debug/elf, const R_390_PC16DBL = 17
pkg debug/elf, const R_390_PC16DBL R_390
pkg debug/elf, const R_390_PC32 = 5
pkg debug/elf, const R_390_PC32 R_390
pkg debug/elf, const R_390_PC32DBL = 19
pkg debug/elf, const R_390_PC32DBL R_390

O valor do *parâmetro da rota* será um *membro de enumeration*.

#### Compare *membros de enumeration*

Você pode comparar eles com o *membro de enumeration* no enum `ModelName` que você criou:

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

#### Obtenha o *valor de enumerate*

Você pode ter o valor exato de enumerate (um `str` nesse caso) usando `model_name.value`, ou em geral, `your_enum_member.value`:
