electron 实现文件下载管理器(1)

主进程实现代码：

/**

• 打开文件选择框

• @param oldPath - 上一次打开的路径

*/

const openFileDialog = async (oldPath: string = app.getPath(‘downloads’)) => {

if (!win) return oldPath

const { canceled, filePaths } = await dialog.showOpenDialog(win, {

title: ‘选择保存位置’,

properties: [‘openDirectory’, ‘createDirectory’],

defaultPath: oldPath,

})

return !canceled ? filePaths[0] : oldPath

}

ipcMain.handle(‘openFileDialog’, (event, oldPath?: string) => openFileDialog(oldPath))

渲染进程代码：

const path = await ipcRenderer.invoke(‘openFileDialog’, ‘PATH’)
