HarmonyOS 鸿蒙Next保存图片到相册的上架问题

最初保存图片到相册申请了ohos.permission.WRITE_IMAGEVIDEO权限说上架不让那么大的权限，我们就把图片保存到下载，使用的下面的代码

// 创建文件管理器保存选项实例
const photoSaveOptions = new picker.PhotoSaveOptions()
let extension: string = ‘jpg’;
// 获取当前时间戳(毫秒)，给图片命名
let timestamp: number = new Date().getTime()
// 保存文件名（可选），方括号里的文件名自定义，每次不能重复，设备里已有这个文件的话，名字就需要改个不一样的，不然接口会报错
photoSaveOptions.newFileNames = [${timestamp}niuPhoto.${extension}]
const photoViewPicker = new picker.PhotoViewPicker()
try {
photoViewPicker.save(photoSaveOptions).then((photoSaveResult) => {
if (photoSaveResult != undefined && photoSaveResult.length > 0) {
Log.i(this.TAG, ‘photoViewPicker.save to file succeed and uris are:’ + photoSaveResult)
complete(true, photoSaveResult[0])
} else {
complete(false, “”)
}
})
} catch (error) {
if (Log.enable()) {
let err: BusinessError = error as BusinessError
Log.i(this.TAG, [picker] Invoke photoViewPicker.save failed, code is ${err.code}, message is ${err.message})
}
complete(false, “”)
}

现在picker.PhotoViewPicker废弃了，我们可以直接使用https://developer.huawei.com/consumer/cn/doc/harmonyos-faqs-V5/faqs-image-9-V5中的photoAccessHelper申请ohos.permission.WRITE_IMAGEVIDEO权限保存到相册吗？

let context = getContext(this)
// 申请相册管理模块权限’ohos.permission.READ_IMAGEVIDEO’
let phAccessHelper = photoAccessHelper.getPhotoAccessHelper(context);
Log.i(this.TAG, getAlbumsCallback ${<span class="hljs-built_in">JSON</span>.stringify(phAccessHelper)})
let photoType: photoAccessHelper.PhotoType = photoAccessHelper.PhotoType.IMAGE;
let extension: string = ‘jpg’;
// 获取当前时间戳(毫秒)，给图片命名
let timestamp: number = new Date().getTime()
let options: photoAccessHelper.CreateOptions = {
title: ${timestamp}niuPhoto
}
phAccessHelper.createAsset(photoType, extension, options, (err, uri) => {
if (uri !== undefined) {
complete(uri)
} else {
Log.i(this.TAG, '创建相册路径失败 err.code : ’ + err.code + ', err.message : ’ + err.message)
complete("")
}
})
