HarmonyOS 鸿蒙Next App获取相册图片的问题

使用Image组件,展示沙箱路径图片，需要得到文件沙箱路径后, 调用[@ohos](/user/ohos).file.fileuri模块的fileuri.getUriFromPath(file.path)将沙箱路径转化为沙箱uri, 传入之后即可正常显示，见如下demo:

import fileUri from '[@ohos](/user/ohos).file.fileuri';
import common from '[@ohos](/user/ohos).app.ability.common';
import fs from '[@ohos](/user/ohos).file.fs';
[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
 [@State](/user/State) message: string = 'Hello World';
 [@State](/user/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%')
 }
}
