如果您使用的是.NET客户端库,请尝试查看带有URI的CloudBlockBlob.StartCopyFromBlob.

string accountName = "accountname";
string accountKey = "key";
string newFileName = "newfile2.png";
string destinationContainer = "destinationcontainer";
string sourceUrl = "http://www.site.com/docs/doc1.xls";

CloudStorageAccount csa = new CloudStorageAccount(new StorageCredentials(accountName, accountKey), true);
CloudBlobClient blobClient = csa.CreateCloudBlobClient();
var blobContainer = blobClient.GetContainerReference(destinationContainer);
blobContainer.CreateIfNotExists();
var newBlockBlob = blobContainer.GetBlockBlobReference(newFileName);
newBlockBlob.StartCopyFromBlob(new Uri(sourceUrl), null, null, null);
