HarmonyOS如何实现粘贴板功能

import { pasteboard } from '@kit.BasicServicesKit'; 
@State message: string = 'Hello World' 
Text(this.message).onClick(() => { 
  const pasteboardData = pasteboard.createData(pasteboard.MIMETYPE_TEXT_PLAIN, this.message) 
  const systemPasteboard = pasteboard.getSystemPasteboard() 
  systemPasteboard.setData(pasteboardData) //将数据放入剪切板 
  systemPasteboard.getData().then((data) => { 
    if (data) { 
      promptAction.showToast({ message: "复制成功" }) 
    } else { 
      promptAction.showToast({ message: "复制失败" }) 
    } 
  }) 
})
