参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-bundlemanager-V5#bundlemanagercanopenlink12

参考demo：

import bundleManager from '@ohos.bundle.bundleManager';
import { BusinessError } from '@ohos.base';
import hilog from '@ohos.hilog';
try {
    let link = 'xxxx';
    let data = bundleManager.canOpenLink(link);
    hilog.info(0x0000, 'canOpenLink successfully: %{public}s', JSON.stringify(data));
} catch (err) {
    let message = (err as BusinessError).message;
    hilog.error(0x0000, 'canOpenLink failed: %{public}s', message);
}
