在电子渲染过程中，我想获取一个W3C文件对象，它是一个本地路径文件，我该怎么办？

Question

我的本​​地文件在/opt/local/testdir/test.txt

const requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem
const persistentStorage = navigator.persistentStorage || navigator.webkitPersistentStorage
const resolveLocalFileSystemURL = window.resolveLocalFileSystemURL || window.webkitResolveLocalFileSystemURL
const DEFAULT_MAX_SIZE = Number.MAX_SAFE_INTEGER
resolveLocalFileSystemURL(
    'filesystem:file:///persistent//opt/local/testdir/test.txt',
    entry => {
        debug('resolveLocalFileSystemURL entry: %O', entry)
    },
    err => debug('resolveLocalFileSystemURL %O', err),
)

发生以下错误

It was determined that certain files are unsafe for access within a Web application, or that too many calls are being made on file resources.

我的目标是获取W3C File或FileList对象。
