Question

我正在使用Microsoft Azure Java SDK上传页面Blob（大小：20G / 40G）。在上传过程中，SDK会抛出存储异常：

SDK版本：

<groupId>com.microsoft.azure</groupId>
<artifactId>azure-storage</artifactId>
<version>1.2.0</version>

请注意，此错误会在随机上传中显示：转移字节数：27325890560，总计42949673472

Linux Box上是否有时间漂移导致此问题？任何其他指针都会有所帮助。

调用Azure Java SDK API以上传页面blob的代码段：

String storageAccntName = "storageAccount";

URI blobEndpoint = null;
String uriString = "http://" + storageAccntName + ".blob.core.windows.net";
blobEndpoint = new URI(uriString);

CloudBlobClient blobClient = new CloudBlobClient(blobEndpoint, new StorageCredentialsAccountAndKey(storageAccntName, blobInfo.getAccessKey()));
blobClient.setAuthenticationScheme(AuthenticationScheme.SHAREDKEYFULL);
blobClient.getDefaultRequestOptions().setRetryPolicyFactory(new RetryLinearRetry());

//Create Storage Container
CloudBlobContainer container = blobClient.getContainerReference(Constants.STORAGE_CONTAINER_NAME);
container.createIfNotExists();

//Creating Page Blob corresponding to each disk
CloudPageBlob pageBlob = container.getPageBlobReference("pageBlobName");
File vhdFile  = new File("pageBlobName");
if(vhdFile.length()==0) {
    throw new CPMException("Invalid file with length 0. Stopping upload for file with path: " + vhdFile.getAbsolutePath()
            + " and file name: " + diskBlob.getLocation());
}
LOG.debug("Blob size for Disk: " + diskBlob.getName() + " is: " + vhdFile.length());

pageBlob.create(vhdFile.length());
blobClient.getDefaultRequestOptions().setConcurrentRequestCount(Constants.MAX_CONSUMER_THREADS);
pageBlob.upload(new FileInputStream(vhdFile), vhdFile.length());

如果您使用共享访问签名上传文件，并且SAS的有效期已过期，则可能会发生这种情况。根据您的blob大小，此上传文件将被拆分为多个请求，并且在稍后的请求发出时，SAS可能已过期。

如果您使用的是存储帐户和密钥而不是SAS，请粘贴遇到此问题的代码段。

将页面Blob上载到Azure获取错误：确保正确形成Authorization标头的值
