Azure blob存储 - 在SAME容器中复制块blob

Question

我正在使用带有Android API的Azure存储。我正在尝试将一个块blob从一个位置复制到另一个位置（在SAME blob容器中）。

然而，当我制作副本时，我在调用startCopy方法后出现“CannotVerifyCopySource”错误。

示例代码：

private void sample(String path1, String path2, File file) {

    CloudBlockBlob blob1 = container.getBlockBlobReference(path1);
    CloudBlockBlob blob2 = container.getBlockBlobReference(path2);

    blob1.upload(new FileInputStream(file), file.length());
    blob1.startCopy(blob2);
}

关于可能出现什么问题的任何想法？

致以最诚挚的问候，

请参阅以下有关startCopy的来源。我想你应该在这里使用blob2.startCopy(blob1)。

/**
     * Requests the service to start copying a block blob's contents, properties, and metadata to a new block blob.
     *
     * @param sourceBlob
     *            A <code>CloudBlockBlob</code> object that represents the source blob to copy.
     *
     * @return A <code>String</code> which represents the copy ID associated with the copy operation.
     *
     * @throws StorageException
     *             If a storage service error occurred.
     * @throws URISyntaxException
     */
    @DoesServiceRequest
    public final String startCopy(final CloudBlockBlob sourceBlob) throws StorageException, URISyntaxException {
        return this.startCopy(sourceBlob, null /* sourceAccessCondition */,
                null /* destinationAccessCondition */, null /* options */, null /* opContext */);
    }
