你可以把 `.openapi_schema` 屬性當作「快取」來儲存已產生的結構。

這樣使用者每次開啟 API 文件時，應用就不必重複產生結構。

結構只會產生一次，之後的請求都會使用相同的快取結果。

### 覆寫方法 { #override-the-method }

現在你可以用新的函式取代 `.openapi()` 方法。

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### 檢查看看 { #check-it }

        assertEquals("21T", crawlingConfigHelper.getDefaultConfig(ConfigType.DATA).get().getId());
    }

    @Test
    public void test_getId() {
        // Test getId method through reflection since it's protected
        try {
            java.lang.reflect.Method getIdMethod = CrawlingConfigHelper.class.getDeclaredMethod("getId", String.class);
            getIdMethod.setAccessible(true);

        }
        return tmp[0] & 0xFF;
    }

    @Override
    public synchronized int read(final byte[] b) throws IOException {
        return read(b, 0, b.length);
    }

    /* This method will not return until len bytes have been read
     * or the stream has been closed.
     */

    @Override
    public synchronized int read(final byte[] b, int off, int len) throws IOException {
        if (len == 0) {

Она будет создана один раз, а затем тот же кэшированный вариант будет использоваться для последующих запросов.

### Переопределите метод { #override-the-method }

Теперь вы можете заменить метод `.openapi()` на вашу новую функцию.

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### Проверьте { #check-it }

Şema yalnızca bir kez üretilecektir; sonraki request'ler için de aynı cache'lenmiş şema kullanılacaktır.

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[13:14,25:26] *}

### Metodu Override Etme { #override-the-method }

Şimdi `.openapi()` metodunu yeni fonksiyonunuzla değiştirebilirsiniz.

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### Kontrol Edin { #check-it }

// For non-existing objects with object retention headers set, this method returns ErrNone if bucket has
// locking enabled and user has requisite permissions (s3:PutObjectRetention)
// If object exists on object store and site wide WORM enabled - this method
// returns an error. For objects in "Governance" mode, overwrite is allowed if the retention date has expired.

type GetObjectInfoFn func(ctx context.Context, bucket, object string, opts ObjectOptions) (ObjectInfo, error)

// WalkVersionsSortOrder represents the sort order in which versions of an
// object should be returned by ObjectLayer.Walk method
type WalkVersionsSortOrder uint8

const (
	// WalkVersionsSortAsc - Sort in ascending order of ModTime
	WalkVersionsSortAsc WalkVersionsSortOrder = iota
	// WalkVersionsSortDesc - Sort in descending order of ModTime
