我正在尝试使用 Microsoft Graph Java SDK 2.10 将大型（> 4mb）附件上传到 Office 365 中的现有消息。我正在遵循这些说明：https ://docs.microsoft.com/en-us/graph/outlook-large-attachments?tabs=java

我已经成功创建了上传会话，并获得了一个类似于文档中示例的 uploadUrl 值。然后我使用 ChunkedUploadProvider 开始对这个 url 进行 PUT。

        // Create an upload session
        UploadSession uploadSession = client.me()
                .messages(messageId).attachments()
                .createUploadSession(attachmentItem)
                .buildRequest()
                .post();

        ChunkedUploadProvider<AttachmentItem> chunkedUploadProvider =
                new ChunkedUploadProvider<AttachmentItem>
                        (uploadSession, client, fileStream, attachmentItem.size, AttachmentItem.class);

        // Config parameter is an array of integers
        // customConfig[0] indicates the max slice size
        // Max slice size must be a multiple of 320 KiB
        int[] customConfig = { 12 * 320 * 1024 }; // still < 4MB as API recommended

        // Do the upload
        try {
            chunkedUploadProvider.upload(callback, customConfig);
        } catch (Exception e) {
            log.error("Upload attachment file name {} for message id {}", fileAttachment.name, messageId, e);
        }

我的问题是我得到 http 401 (Unauthorized) 作为响应：

{
  "error": {
    "code": "InvalidMsaTicket",
    "message": "ErrorCode: \u0027PP_E_RPS_CERT_NOT_FOUND\u0027. Message: \u0027 Internal error: spRPSTicket-\u003eProcessToken failed.

    "innerError": {

      "date": "2020-09-17T04:55:15"
    }
  }
}

我注意到创建上传会话的请求是：

https://graph.microsoft.com/v1.0/me/messages/AQMkADAwATM3ZmYAZS0xNWU2LTc4N1agAAAA==/attachments

而uploadUrl是：

https://outlook.office.com/api/v2.0/Users('00037ffe-15e6-787e-0000-00000')/Messages('AQMkADAwATM3ZmYAZS0xNVtUUgAAAA==')/AttachmentSessions('AQMkADAwwAAAA=')?authtoken=eyJhbGciOiJSUzI1NiIsImtpZCI6IktmYUNIUlN6bllHMmNIdDRobk9JQnpndlU5MD0iL

这是一个不同的 API（Graph 与 Outlook）。

我已经添加了邮件 read.write 范围，这允许我创建一个 < 4mb 的附件。在获取访问令牌时，我尝试将“https://outlook.office.com/Mail.ReadWrite”放入范围，但遇到了相同的 invalid_token 问题。我应该怎么做才能解决问题？

任何帮助，将不胜感激。谢谢你。

我的错。请求不应包含授权标头：

不要指定授权请求标头。PUT 查询使用来自 uploadUrl 属性的预验证 URL，该 URL 允许访问https://outlook.office.com域。

删除了 Authorization 标头，请求正常工作。

只需对该 URL 使用普通的 cURL PUT 请求，它就可以工作......在 PHP 中，它将是这样的（使用php-curl-class/php-curl-class和microsoft/microsoft-graph作曲家库）：

function uploadLargeFileData(Graph $graph, string $messageId, string $fileName, string $fileContentType, string $fileData) : bool {

  $fileSize = strlen($fileData);
  // create upload session
  $attachmentItem = (new AttachmentItem())
    ->setAttachmentType('file')
    ->setName($fileName)
    ->setSize($fileSize)
    ->setContentType($fileContentType);

  /** @var UploadSession $uploadSession */
  try {
    $uploadSession = $graph->createRequest('POST', "/me/messages/{$messageId}/attachments/createUploadSession")
      ->addHeaders(['Content-Type' => 'application/json'])
      ->attachBody(['AttachmentItem' => $attachmentItem])
      ->setReturnType(UploadSession::class)
      ->execute();
  }
  catch (GraphException $e) {
    return false;
  }

  $fileData = str_split($fileData, self::LargeFileChunkSize);
  $fileDataCount = count($fileData);

  foreach ($fileData as $chunkIndex => $chunkData) {
    $chunkSize = strlen($chunkData);
    $rangeStart = $chunkIndex * self::LargeFileChunkSize;
    $rangeEnd = $rangeStart + $chunkSize - 1;

    try {
      // we need to use this plain access, because calling the API via the Graph provider leads to strange error of invalid audience
      $curl = new Curl();
      $curl->setHeaders([
          'Content-Length' => $chunkSize,
          'Content-Range' => "bytes {$rangeStart}-{$rangeEnd}/{$fileSize}",
          'Content-Type' => 'application/octet-stream',
        ]);

      $curl->put($uploadSession->getUploadUrl(), $chunkData);

      if ($chunkIndex < $fileDataCount - 1 && $curl->httpStatusCode != 200) { // partial are responding with 200
        return false;
      }
      elseif ($chunkIndex == $fileDataCount - 1 && $curl->httpStatusCode != 201) { // last response should have code 201
        return false;
      }
    }
    catch (\Exception $e) {
      return false;
    }
  }

  return true;
}
