我需要一些有关cordova-plugin-file 的帮助来备份Windows 10 App 中cordova-sqlite-storage 使用的数据库。我的代码在 Android 平台上运行良好。数据库可以双向复制（备份和恢复）。该应用程序使用的数据库似乎如下：
C:\Users\myuser\AppData\Local\Packages\io.cordova.hellocordova_h35559jr9hy9m\LocalState\sample.db
应用程序尝试使用此位置来定位文件，但未找到：
ms-appx:///databases/sample.db
如何获得 Windows 复制文件的正确位置？
这是我用来复制文件的代码：
备份数据库（名称：字符串）：承诺 {
return new Promise<boolean>((resolve, reject) =>
{
var fileName: string = window.cordova.file.applicationStorageDirectory + 'databases/' + name;
var directoryName: string = window.cordova.file.externalRootDirectory;
window.resolveLocalFileSystemURL(fileName, (file: FileEntry) => {
console.log('[!] Database exists: ' + fileName);
console.log('[!] Storage: ' + directoryName);
window.resolveLocalFileSystemURL(directoryName, (directory: DirectoryEntry) => {
console.log('[!] Directory: ' + directory.toURL());
directory.getDirectory("Backup", {create: true, exclusive: false}, (directoryBackup: DirectoryEntry) => {
console.log('[!] Directory: ' + directoryBackup.toURL());
file.copyTo(directoryBackup, name, (copiedFile: Entry) => {
console.log('[!] Copy success');
resolve(true);
}, (error: FileError) => {
console.log('[!] Copy failed: ' + error.code);
reject(error);
});
}, (error: FileError) => {
console.log('[!] Backup Directory not found: ' + directoryName + 'Backup' + ' errorcode: ' + + error.code);
reject(error);
})
}, (error: FileError) => {
console.log('[!] Directory not found: ' + directoryName + ' errorcode: ' + + error.code);
reject(error);
});
}, (error: FileError) => {
console.log('[!] Database not found: ' + fileName + ' errorcode: ' + + error.code);
reject(error);
});
});
