c# – 使用Azure存储客户端库的v2进行共享访问签名时出现404错误

这是我的实际代码：
服务器端,生成SAS：

var myAccount = CloudStorageAccount.Parse(
                  ConfigurationManager.ConnectionStrings[
                              "AzureStorageConnectionString"].ConnectionString);
var myContainer = myAccount.CreateCloudBlobClient()
                                          .GetContainerReference(containerName);
myContainer.CreateIfNotExists();

string blobName = "Imports/" + DateTime.UtcNow.ToString("yyyy-MM-dd_HH-mm-ss") 
                             + ".zip";
var myBlob = myContainer.GetBlockBlobReference(blobName);
using (var stream = 
 new MemoryStream(System.Text.Encoding.UTF8.GetBytes("Hey,I'm empty for now.")))
{
    myBlob.UploadFromStream(stream);
}

var sharedAccesSignature = myBlob.GetSharedAccessSignature(
                 new Microsoft.WindowsAzure.Storage.Blob.SharedAccessBlobPolicy()
{
   Permissions = 
       Microsoft.WindowsAzure.Storage.Blob.SharedAccessBlobPermissions.Write 
       | Microsoft.WindowsAzure.Storage.Blob.SharedAccessBlobPermissions.Read,SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),});

return myBlob.Uri.AbsoluteUri + sharedAccesSignature;

它在客户端尝试了很多东西,有时导致404或403服务器错误.
例如,我试过这个(结果：404)：

var blobClient = new CloudBlobClient(new Uri(blobWithSharedAccessSignature));
// blobWithSharedAccessSignature here is : https://azertyuiop.blob.core.windows.net/container1/Imports/2012-12-01_19-43-54.zip?sv=2012-02-12&se=2012-12-01T20%3A43%3A54Z&sr=b&sp=rw&sig=h0bTUk[...]3D
// calling blobWithSharedAccessSignature from a webBrowser works.
// result here is valid for containerName : container1
var container = blobClient.GetContainerReference(containerName);
ICloudBlob blobRef = container.GetBlobReferenceFromServer(blobWithSharedAccessSignature);   ==> error 404
using (var fileStream = File.OpenRead(fileFullPath))
{
    blobRef.UploadFromStream(fileStream);
}

我试过更换

container.GetBlobReferenceFromServer(blobWithSharedAccessSignature);

通过

container.GetBlockBlobReference(blobWithSharedAccessSignature);

我也试过更换

blobClient = new CloudBlobClient(new Uri(blobWithSharedAccessSignature));

通过

blobClient = new CloudBlobClient(new Uri(blobWithSharedAccessSignature),new StorageCredentials(blobWithSharedAccessSignature));

这导致“403 – 禁止”错误.

有人可以通过在v2中提供完整样本来帮助我吗？或者告诉我这是我的错误？谢谢 ！

更新 – 解决方案:(感谢Sandrino Di Mattia)
