HarmonyOS鸿蒙Next中选择pdf文档之后，如何在应用中打开 选择pdf文档之后，如何在应用中打开

我已经将pdf推送到开发板，然后获取到的路径是datashare:///media/file/24，我咋显示到页面上

import picker from '@ohos.file.picker';

@Entry
@Component
struct FilePickPage {
  @State message: string = '文档选择器'

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold).onClick(() =>{
          const documentSelectOptions = new picker.DocumentSelectOptions();
          const documentViewPicker = new picker.DocumentViewPicker(); // 创建文件选择器实例
          documentViewPicker.select(documentSelectOptions)
            .then((documentSelectResult) =>{
              let uri = documentSelectResult[0];
              // 获取到到文档文件的URI后进行文件读取等操作
            })
            .catch((err) =>{
              console.error(`Invoke documentPicker.select failed, code is ${err.code}, message is ${err.message}`);
            })
        })
      }
      .width('100%')
    }
    .height('100%')
  }
}
