可以通过访问系统剪切板实现，参考以下demo：

//设置剪贴板数据
export function SetPasteboardData() {
  let plainTextData = new unifiedDataChannel.UnifiedData();
  let plainText = new unifiedDataChannel.PlainText();
  plainText.details = {
    Key: 'test1234',
    Value: 'test1234',
  };
  plainText.textContent = 'test1234';
  plainText.abstract = 'test1234';
  plainTextData.addRecord(plainText);

  let systemPasteboard: pasteboard.SystemPasteboard = pasteboard.getSystemPasteboard();
  try {
    systemPasteboard.setUnifiedDataSync(plainTextData);
    console.info('tag, Succeeded in setting UnifiedData.');
  } catch (err) {
    console.error('tag, Failed to set UnifiedData. Cause:' + err.message);
  };
}

//获取剪贴板数据
export function GetPasteboardData() {
  let systemPasteboard: pasteboard.SystemPasteboard = pasteboard.getSystemPasteboard();
  try {
    let result: unifiedDataChannel.UnifiedData = systemPasteboard.getUnifiedDataSync();
    console.info('tag, Succeeded in getting UnifiedData.');
  } catch (err) {
    console.error('tag, Failed to get UnifiedData. Cause:' + err.message);
  };
}
