            if (src.endWith(".png") || src.endWith(".jpg") || src.endWith(".jpeg")) {
                this.imageArray.push({
                    src: src // image显示本地图片需要使用file协议
                })
            }
        }
    }

})

要显示视频缩略图的话需要使用组件，即：

<view v-for="(item, index) in videoArray" class="file">
    <wrs-image  :videoId="item.videoId" style="width: 50px; height: 50px; background-color: #eeeeee;"
        :mode="mode"></wrs-image>
</view>

videoId属性值得是Android数据模型的_id、iOS数据模型的localIdentifier，即：

if (this.isAndroid) {
    model.videoId = model._id + ""
} else {
    model.videoId = model.localIdentifier + ""
}

获取音频文件

var params = {}
// params参数和返回模型参考【获取相册图片数据】的参数
UTSGetFiles.getAudios(params, (resp) => {
    var fileArray = resp.fileArray
    if (fileArray && fileArray.length > 0) {
        this.imageArray.length = 0
        this.imageArray = []
        for (var i = 0; i < fileArray.length; i++) {
            var model = fileArray[i]
            if(this.isAndroid) {
                var _data = model._data
                this.imageArray.push({
                    src: "file://" + _data // image显示本地图片需要使用file协议
                })
            } else {
                var path = model.path
                this.imageArray.push({
                    src: path // image显示本地图片需要使用file协议
                })
            }
        }
    }
    // console.log(JSON.stringify(resp))
})

获取访问相册权限(仅支持iOS)

如果要在页面上使用显示图片的话，页面需要用nvue

    UTSGetFiles.requestAuthorization((resp) => {
        // 0: PHAuthorizationStatusNotDetermined
        // 1: PHAuthorizationStatusRestricted
        // 2: PHAuthorizationStatusDenied
        // 3: PHAuthorizationStatusAuthorized
        // 4: PHAuthorizationStatusLimited API_AVAILABLE(ios(14))
        let status = resp.status

    console.log(JSON.stringify(resp))
})
