HarmonyOS 怎么把内容复制到剪切板

Button('Write').onClick(() => { 
  let pasteData: pasteboard.PasteData = pasteboard.createData(pasteboard.MIMETYPE_TEXT_PLAIN, 'content'); 
  pasteboard.getSystemPasteboard().setData(pasteData).then(() => { 
    console.info('...Succeeded in setting PasteData.'); 
  }).catch((err: BusinessError) => { 
    console.error('...Failed to set PasteData. Cause: ' + err.message); 
  }); 
}); 
 
Button('Read').onClick(() => { 
  let str: string = pasteboard.getSystemPasteboard().getDataSync().getPrimaryText(); 
  console.info('...str:' + str) 
});
