本地文件下载保存

var timestampInSeconds = Math.floor(new Date().getTime() / 1000)
let staticFilePath = plus.io.convertLocalFileSystemURL('/static/x.xlsm');
plus.android.requestPermissions(['android.permission.WRITE_EXTERNAL_STORAGE'],() => {// 2. 复制文件到下载目录plus.io.resolveLocalFileSystemURL(staticFilePath, (entry) => {plus.io.resolveLocalFileSystemURL('/storage/emulated/0/', (root) => {entry.copyTo(root,`downloaded_`+timestampInSeconds+`.xlsm`, (newEntry) => {uni.showToast({ title: '文件已保存' });// 3. 尝试打开文件plus.runtime.openFile(newEntry.fullPath);});});});}
