java - Microsoft Word 忽略从 WebDAV 服务器发送的锁定状态

Question

我正在使用自定义WebDAV implementation (基于java servlet)。这似乎在很大程度上运作良好 - 除了 Microsoft Word 不会报告锁定文档已锁定给用户。因此，用户可以编辑文档，直到他们尝试保存文档为止，此时用户会在 Microsoft Word 中看到一条不友好的“上传失败”消息。

我的问题的主要目的是了解我是否可以修改 WebDAV 响应以便执行以下一项或多项操作:

1. 让 Microsoft Word 向用户显示一条消息，说明文档当前已锁定。
2. 如果存在锁定，则强制 Microsoft Word 以只读状态打开文档。

我运行了 fiddler 并分析了请求和响应轨迹，与 specifications for WebDAV 进行了比较。 。我有点不确定接下来该去哪里，所以非常欢迎任何 WebDAV 专家的帮助!

从此时起，Microsoft Word 似乎会轮询服务器，尝试获取文档的锁定。用户仍然不知道文档被锁定。我认为这证明了 Word 知道锁。

Answer 1

响应 2 有多个问题:

• 状态代码和正文；请参阅http://greenbytes.de/tech/webdav/rfc4918.html#rfc.section.9.10.7

• DAV:href 元素的内容已损坏(例如，“:”已进行百分比转义)

• 没有 Lock-Token 响应头字段
