Следующие разделы не обязательно являются «продвинутыми».

И возможно, что решение для вашего варианта использования находится в одном из них.

## Сначала прочитайте руководство { #read-the-tutorial-first }

В следующих разделах предполагается, что вы уже прочитали основной [Учебник — Руководство пользователя: Безопасность](../../tutorial/security/index.md).

        // Should return true when read caching is enabled
        assertTrue(DirectoryLeaseState.canCacheEnumeration(Smb2LeaseState.SMB2_LEASE_READ_CACHING));
        assertTrue(DirectoryLeaseState.canCacheEnumeration(DirectoryLeaseState.DIRECTORY_READ_HANDLE));
        assertTrue(DirectoryLeaseState.canCacheEnumeration(DirectoryLeaseState.DIRECTORY_FULL));

        // Should return false when read caching is not enabled

* `write(data)`：将 `data` (`str` 或 `bytes`) 写入文件。
* `read(size)`：读取文件中 `size` (`int`) 个字节/字符。
* `seek(offset)`：移动到文件中字节位置 `offset` (`int`)。
    * 例如，`await myfile.seek(0)` 会移动到文件开头。
    * 如果你先运行过 `await myfile.read()`，然后需要再次读取内容时，这尤其有用。
* `close()`：关闭文件。

由于这些方法都是 `async` 方法，你需要对它们使用 await。

例如，在 `async` *路径操作函数* 内，你可以这样获取内容：

```Python
contents = await myfile.read()
```

    }

    @Test
    void testReadParameterWordsWireFormat() {
        byte[] buffer = new byte[1024];
        int result = response.readParameterWordsWireFormat(buffer, 0);

        // The method should read parameter words
        assertTrue(result >= 0, "readParameterWordsWireFormat should return non-negative value");
    }

    @Test
    void testWriteBytesWireFormat() {
        byte[] dst = new byte[1024];
