使用DotCMIS，我可以成功地启动与Alfresco 4.0.1 CMIS服务器的会话。
但是当我打电话给session.GetRootFolder()时，我得到以下异常：

一个重要的部分似乎是：Read by order only possible for encoded/bare format
我的代码几乎直接来自教程：
using System;
using System.Collections.Generic;
using DotCMIS;
using DotCMIS.Client.Impl;
using DotCMIS.Client;
using DotCMIS.Data.Impl;
using DotCMIS.Data.Extensions;
namespace tests.sln
{
class MainClass
{
public static void Main (string[] args)
{
// Connect to repository
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters[SessionParameter.BindingType] = BindingType.AtomPub;
parameters[SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/cmisatom";
parameters[SessionParameter.User] = "admin";
parameters[SessionParameter.Password] = "admin";
SessionFactory factory = SessionFactory.NewInstance();
ISession session = factory.GetRepositories(parameters)[0].CreateSession();
Console.WriteLine("Created CMIS session: " + session.ToString());
// Get the root folder
IFolder rootFolder = session.GetRootFolder(); // Error happens here
}
}
}
我错过了什么？
在调试模式下，我可以看到堆栈中的DotCMIS.Client.Impl.Session.GetObject (objectId="workspace://SpacesStore/77acb21f-811c-49a3-be4d-5cc7f177f461"，不确定这意味着什么，但77acb21f-811c-49a3-be4d-5cc7f177f461确实是Alfresco company_home的节点引用。
如果我在上面的代码中将 URL 更改为 http://localhost:8080/alfresco/service/cmisatom，则GetRepositories行会出现较早的Not Found错误。所以我很确定我的 URL 是正确的。
我下载了DotCMIS源代码，现在正在Monodevelop中调试它。
使用Wireshark，我已经确定了发生异常的数据包：

您正在使用旧的AlfrescoCMIS URL。
