从外部正常关闭Electron Client

Question

我们有一个电子客户端应用程序，必须通过公司范围的软件管理系统进行部署和更新。

目前，在安装更新之前，正在运行的Electron客户端应用程序被简单地“杀死”。

在Windows10下，有没有办法告诉Electron客户端正常关闭(内部应用关闭事件或另一个事件应该运行)

Answer 1

对于windows，Electron可以在后台进程中处理graceful-exit，对于Linux，可以在后台进程中处理SIGTERM。

要“礼貌地”要求应用程序关闭：

• 使用不带/f - details的taskkill。(Windows)
• 使用pkill -TERM <proc-name>代替kill details (linux)

// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    console.log('if you see this message - all windows was closed')
    app.quit()
  }
})

app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (BrowserWindow.getAllWindows().length === 0) createWindow()
})

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', async () => {
  createWindow()
})

// Exit cleanly on request from parent process.
if (process.platform === 'win32') {
  // this message usually fires in dev-mode from the parent process
  process.on('message', (data) => {
    if (data === 'graceful-exit') {
      console.log('if you see this message - graceful-exit fired')
      app.quit()
    }
  })
} else {
  process.on('SIGTERM', () => {
    console.log('if you see this message - SIGTERM fired')
    app.quit()
  })
}
