我有一个使用Sphoirum webdav服务器构建的自定义WebDAV服务器，它驻留在ASP.NET MVC3应用程序中。这是一个.Net 4.0项目。
文档存储库是一个SharePoint，我们的MVC应用程序是它的前端，并通过WebDAV公开整个事物。请注意，我们的IIS 7.5上没有启用WebDAV发布。
我已经实现了以下HTTP谓词：
现在，当我打开word文档时，它首先处于只读模式。获得锁定并进入编辑模式是成功的，但是当我想在文档中保存更改时，我得到以下内容：
您的更改已保存，但由于错误而无法上传。
诀窍是文档确实正确保存到存储库，而我们的WebDAV服务器对word的响应是HTTP / 200，但Word仍然抱怨。 我也尝试直接从SharePoint存储库中编辑Word，只是为了确认我的Office没有被破坏 - 一切正常。
以下是从Word保存文档时PUT请求的响应：

所以我试图模仿SharePoint发布的一些标题，例如 MicrosoftSharePointTeamServices ，但无济于事。
答案 0 :(得分：3)
顺便说一句，我发现Sphorium webdav中的错误导致了这个问题。该错误出现在方法 DavLockBase_InternalProcessDavRequest（）中，错误的代码行是：
string[] _lockTokens = this.RequestLock.GetLockTokens();
应该是：
string[] _lockTokens = this.ResponseLock.GetLockTokens();
在更改之后，在Word 2010中保存文件工作正常。
答案 1 :(得分：1)
如果有人再遇到这个问题，这里有一个基于上述答案构建的修复程序，以及我在使用单词2010时找到的内容。基本上修复涉及替换＆＃34; DavLockBase_InternalProcessDavRequest＆的代码＃34;方法（我已经为每个＆＃34;更正＆＃34;添加了一些评论。）
作为一个注释（找到一些信息here）：word20的webdav实现的行为在客户端是否安装了补丁方面有所不同;因此，在所有情况下都可能不需要进行第3次校正！
希望它有所帮助！

观察：锁定令牌使用无效语法（Sharepoints也是如此）。也;大多数这些标题不应该被需要（是专有的）或者不适用于PUT响应（例如Lock-Token）。
我建议先尝试使用mod_dav发布到Apache，然后观察HTTP交换。
