android - Azure Blob 存储 - 在同一容器中复制 block Blob

Question

我正在将 Azure 存储与 Android API 结合使用。我正在尝试将一个 block blob 从一个位置复制到另一个位置(在同一个 blob 容器中)。

但是，当我进行复制时，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);
}

对可能出现的问题有什么想法吗？

最诚挚的问候，

请参阅下面有关 startCopy 的源代码。我认为你应该在这里使用 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 */);
    }
