### 理解這段程式碼 { #understand-that-code }

重點就是在 `Annotated` 中使用「`AfterValidator` 搭配函式」。如果你願意，可以略過這一節。🤸

---

但如果你對這個範例感到好奇且仍有興致，以下是一些額外細節。

#### 使用 `value.startswith()` 的字串 { #string-with-value-startswith }

你注意到了嗎？字串的 `value.startswith()` 可以接收一個 tuple，並逐一檢查 tuple 中的每個值：

{* ../../docs_src/query_params_str_validations/tutorial015_an_py310.py ln[16:19] hl[17] *}

#### 隨機項目 { #a-random-item }

    public boolean containsKey(Object key) {
      return standardContainsKey(key);
    }

    @Override
    public boolean containsValue(Object value) {
      return standardContainsValue(value);
    }

    @Override
    public void putAll(Map<? extends K, ? extends V> map) {
      standardPutAll(map);
    }

      for (i in 0 until size) {
        if (!"Vary".equals(name(i), ignoreCase = true)) {
          continue
        }

        val value = value(i)
        if (result == null) {
          result = TreeSet(String.CASE_INSENSITIVE_ORDER)
        }
        for (varyField in value.split(',')) {
          result.add(varyField.trim())
        }
      }
      return result ?: emptySet()
    }

   * an application-specified ordering of lock acquisitions. The application defines the allowed
   * ordering with an {@code Enum} whose values each correspond to a lock type. The order in which
   * the values are declared dictates the allowed order of lock acquisition. In other words, locks
   * corresponding to smaller values of {@link Enum#ordinal()} should only be acquired before locks
   * with larger ordinals. Example:
   *
   * {@snippet :

            request.writeBytesWireFormat(smallBuffer, 0);
        });

        // Test with file ID having maximum byte values
        byte[] maxFileId = new byte[16];

#### Получение *значения перечисления* { #get-the-enumeration-value }

Можно получить фактическое значение (в данном случае - `str`) с помощью `model_name.value` или в общем случае `your_enum_member.value`:

{* ../../docs_src/path_params/tutorial005_py310.py hl[20] *}

/// tip | Подсказка

Значение `"lenet"` также можно получить с помощью `ModelName.lenet.value`.
