我通过 DotCMIS+HTTPS 从 Alfresco 4.2.0 获得 ChangeLog 更改，如下所示：

string lastTokenOnClient = "1857698"; // actually updated using last token
boolean includeProperties = false;
int maxNumItems = 100;

session.GetContentChanges(lastTokenOnClient, includeProperties, maxNumItems);

虽然它通常有效，但有时它会开始出现此错误（客户端）：

CmisSync.Lib.Cmis.BaseException: Unauthorized ---> DotCMIS.Exceptions.CmisRuntimeException: Unauthorized

这个错误出现在 Alfresco 端：

我看不到呼叫如何在GetContentChanges几分钟内成功，然后Unauthorized在同一个会话中开始返回。

难道我做错了什么？

问题是使用了旧的 CMIS URL http://[host]:[port]/alfresco/cmisatom。

解决方案：

用新的 CMIS URL 替换配置中的那个 URLhttp://[host]:[port]/alfresco/api/-default-/public/cmis/versions/1.0/atom解决了这个问题。
