Question

我目前正在为Outlook开发角度插件，并且该插件的部分功能要求我的远程服务从Outlook中获取电子邮件的附件。

我一直在关注this Docs link here in regards to my functionality.

因此，目前，我可以通过Office.js以我的角度代码获取附件令牌，并将其与ExchangeWebServiceURL一起传递给我的远程服务：

Office.context.mailbox.getCallbackTokenAsync((result) => {
  if (result.status === Office.AsyncResultStatus.Succeeded) {
    this.outlookServiceRequest.attachmentToken = result.value;
  }
});

但是一旦我到达这里

                ExchangeService exchangeService = new ExchangeService();
            exchangeService.Url = new Uri(attachmentsRequest.exchangeWebServiceUrl);
            exchangeService.Credentials = new OAuthCredentials(attachmentsRequest.attachmentToken);

            var attachmentIds = new List<string>();
            foreach (OutlookAttachmentDetails attachment in attachmentsRequest.AttachmentArray)
            {
                attachmentIds.Add(attachment.id);
            }

            var attachmentResponses = exchangeService.GetAttachments(attachmentIds.ToArray(), null, new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.MimeContent));

由于来自ExchangeWebServiceUrl的401未经授权错误，该过程将在GetAttachments调用上失败。

我环顾四周，但是没有人遇到这个问题。我已在清单中为我的“加载到ReadWriteMailbox的加载项”设置了权限，但是问题仍然存在。

我已经尝试通过使用Web浏览器版本的Outlook在Office桌面客户端和Chrome上运行它来尝试此操作，但是遇到相同的问题。

以前有人遇到过吗？

编辑：我应该注意，如果我将凭据设置为

，则可以访问Exchange Web服务。

exchangeService.Credentials = new WebCredentials("myUsername", "MyPassword");

因此似乎带有回调令牌。

已解码的令牌返回以下内容：

{“ nameid”：“ 641fdcd4-10dd-4441-ac93-41f519e4ad41@venom.local”，
“ ver”：“ Exchange.Callback.V1”，“ appctxsender”： “ https://localhost:44364/AddinClient@venom.local”，“ appctx”： “{\” SMTP \ “：\” MyEmail \ “\ ”范围\“：\ ”ParentItemId：AAMkAGY3N2QyYzI2LWRhZTUtNGU3My05MzFmLTYwZGZhZmYyN2QzOQBGAAAAAAAdJ5 + qR8pATpmqkddPNb2NBwBgP9yTrGVtSIiRWRnnYVBWAAAAAAEMAABgP9yTrGVtSIiRWRnnYVBWAAA5fvGXAAA = \“}”， “ iss”：“ 00000002-0000-0ff1-ce00-000000000000@venom.local”，“ aud”： “ 00000002-0000-0ff1-ce00-000000000000/outlook.myemailonline.co.uk@venom.local”，“ exp”：1546249394，“ nbf”：1546249094 }

我尝试调用GetAttachments方法时返回的错误是：

请求失败。远程服务器返回错误：（401）未经授权

我从回调中获得的EWS令牌是：

EWS ExchangeService.GetAttachments使用OAuthCredentials返回401未经授权
