在测试中，上述方法可以获取相册视频的文件地址，但是在部分手机上，将文件地址转换成data上传到服务器时出错了
let data : Data
do {
data = try Data.init(contentsOf: URL.init(string: path))
manager?.put(data, key: key, token: token, complete: { [weak self](info, key, resp) in
}, option: options)
}catch let error {
// 这里报错，打印出来是

通过查资料https://io.upyun.com/2016/03/23/the-real-files-in-alasset-and-phasset/
