### 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 }

        String res = checkMethodBase(searchBody).get("/api/admin/fileconfig/settings").asString();
        List<String> fileConfigList = JsonPath.from(res).getList("response.settings.findAll {it.name.startsWith(\"test_fileconfig\")}.id");
        return fileConfigList.get(0);
    }

    @AfterEach
    void deleteFileConfig() {
        final Map<String, Object> searchBody = new HashMap<>();

     * It should return a string representation of the SmbComNegotiate object.
     */
    @Test
    void testToString() {
        String result = smbComNegotiate.toString();
        assertTrue(result.startsWith("SmbComNegotiate["), "String should start with SmbComNegotiate[");
        assertTrue(result.contains("wordCount=0"), "String should contain wordCount=0");

Ama bu örnek kodun detaylarını merak ediyorsanız, birkaç ek bilgi:

#### `value.startswith()` ile String { #string-with-value-startswith }

Fark ettiniz mi? `value.startswith()` ile bir string, tuple alabilir ve tuple içindeki her değeri kontrol eder:

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

            endpoint = val.toString();
            final String lep = endpoint.toLowerCase();
            if (lep.startsWith("\\pipe\\")) {
                final String iface = (String) INTERFACES.get(lep.substring(6));
                if (iface != null) {
                    int c, p;
                    c = iface.indexOf(':');

    //                                                                       =============
    protected String resolveLabelIfNeeds(final MessageManager messageManager, final Locale locale, final String label) {
        return label.startsWith("labels.") ? messageManager.getMessage(locale, label) : label;
    }
