在主进程中，注册打开的处理程序：

// Open handlers must be added as early as possible
  app.on('open-file', onOpen)
  app.on('open-url', onOpen)

  //...

  app.once('ipcReady', function () {
    processArgv(argv)

你可以对它做任何你想做的事情，例如将它重定向到程序参数以重用处理参数：

function onOpen (e, torrentId) {
  e.preventDefault()

  if (app.ipcReady) {
    // Magnet links opened from Chrome won't focus the app without a setTimeout.
    // The confirmation dialog Chrome shows causes Chrome to steal back the focus.
    // Electron issue: https://github.com/atom/electron/issues/4338
    setTimeout(() => windows.main.show(), 100)

    processArgv([ torrentId ])
  } else {
    argv.push(torrentId) // [to be handled by `processArgv` later anyway]
  }
}
