遇到的错误：The destination storage credentials must contain the account key credentials，参数名: destinationStorageCredentials
解决方法：AccountName与AccountKey参数值错误
AccountName就是存储账户名字
AccountKey值获取方式：打开存储账户-->访问秘钥-->key1或者key2

直接上传文件到资产中调用方法：
var virtualPath = "/UploadFile/Files/";
var path = HttpContext.Current.Server.MapPath(virtualPath);
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
var fileFullPath = $"{path}{fileName}";
try
{
file.SaveAs(fileFullPath);
var ams = new AzureMediaServiceController();
url = ams.DeliverVideo(fileFullPath);
result = true;
msg = $@"上传视频成功";
File.Delete(fileFullPath);
}
catch (Exception ex)
{
msg = "上传文件写入失败：" + ex.InnerException + ex.Message + ex.InnerException?.InnerException + "fileFullPath=" + fileFullPath;
}
因为使用的是HTML自带的file上传控件，传递给接口的文件地址全路径是错误的，所以只能保存到接口服务器本地，上传到azure上去之后再删除这个文件。
上传blob到ams
var ams = new AzureMediaServiceController();
var t = ams.UploadBlobFile(fileUrl);
