如何使用Image加载沙箱路径图片资源

import fileUri from '@ohos.file.fileuri'; 
import common from '@ohos.app.ability.common'; 
import fs from '@ohos.file.fs'; 
 
@Entry 
@Component 
struct Index { 
  @State message: string = 'Hello World'; 
  @State uri: string = "" 
 
  build() { 
    Row() { 
      Column() { 
        Text(this.message) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
          .onClick(() => { 
            let context = getContext(this) as common.UIAbilityContext 
            let filePath = context.filesDir + "/test.png" 
            let arrayBuff = context.resourceManager.getRawFileContentSync("icon.png").buffer 
            console.log('testTag-----',arrayBuff) 
            let file = fs.openSync(filePath,fs.OpenMode.CREATE | fs.OpenMode.READ_WRITE) 
            fs.writeSync(file.fd,arrayBuff) 
            this.uri = fileUri.getUriFromPath(filePath) 
            console.log('testTag-----',filePath) 
          }) 
        Image(this.uri) 
          .width(100) 
          .height(100) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
