Question

当您从Graph API获得“ UnknownError”时，有人知道该怎么做吗？还是询问微软的合适网站？

谢谢

请求： https://graph.microsoft.com/v1.0/users/[USER_ID]/messages?$select=id,receivedDateTime&$filter=receivedDateTime+ge+2016-09-13+and+receivedDateTime+lt+2019-09-14&$orderby=receivedDateTime+asc&$skip=25651&$top=1

响应：

{
  "error": {
    "code": "UnknownError",
    "message": "",
    "innerError": {
      "request-id": "1ea27a29-5491-44d2-824a-0aaee9280c40",
      "date": "2019-09-13T19:48:30"
    }
  }
}

Answer 1

我在Graph API的另一部分遇到相同的错误。我认为这是一个权限错误，最容易测试的方法是使用Graph Explorer。

https://developer.microsoft.com/en-us/graph/graph-explorer

在此处运行请求并为自己分配相关权限。

如果这不起作用，则提出此问题的相关位置似乎在Graph API GitHub上，位于此处https://github.com/microsoftgraph/microsoft-graph-docs

Answer 2

HTTP错误代码将为您提供更多有关错误原因的详细信息。如果是403或401，则是验证错误。如果是500或503，则是服务器错误。

在检索文件和文件夹结构的应用程序上，我现在越来越经常出错。我的解决方法是检测错误，稍等片刻然后重试。

IDriveItemChildrenCollectionPage folderitems = null;
            bool done = false;
            Int16 tries = 0;
            while (!done && tries < 3)
            {

                try
                {

                    DriveItem folderitem = null;
                    if (folder.Equals(""))
                        folderitem = SPclient.Sites[siteId].Lists[listId].Drive.Root.Request().GetAsync().Result;
                    else
                        folderitem = SPclient.Sites[siteId].Lists[listId].Drive.Root.ItemWithPath(folder).Request().GetAsync().Result;
                    folderitems = SPclient.Sites[siteId].Lists[listId].Drive.Items[folderitem.Id].Children.Request().GetAsync().Result;
                done = true;
                }
                catch (Exception ex)
                {
                    if (ex.InnerException != null && ex.InnerException.Message.StartsWith("Code: UnknownError"))
                    {
                        //wait, retry
                        System.Threading.Thread.Sleep(500);
                    }
                    else
                        throw;
                }
                finally
                {
                    tries++;
                }
            }
