UCWA 文档指出，UCWA 当前仅适用于在本地拥有 Lync 的客户。

尽管如此，如果对 Office 365 帐户使用Lync 连接分析器，似乎可以连接到 UCWA 服务：已完成移动性测试 (UCWA) 服务。此外，如果我检查此工具（例如使用 Fiddler）执行的 Web 请求，我可以获取它（以某种方式）从 Office 365 获得的身份验证令牌，并使用它向 UCWA 发出请求。

  • 好像UCWA被Office 365暴露了，是这样吗？Lync 连接分析器似乎使用某个WebTicket 服务来获取身份验证令牌。
  • 是否有任何库可以抽象 WebTicket Service 的使用以获取身份验证令牌？获得令牌后，访问 UCWA 资源将非常简单——不过，一个库也会很好:)
  • 我找不到太多关于 WebTicket 服务 (WCF) 的文档。如果我将服务引用（Visual Studio）添加到https://lyncweb.domain.com/WebTicket/WebTicketService.svc，没有太多选项 - 似乎请求和响应消息没有一定的结构，所以调用这个 WebTicket Service 暴露的IssueToken操作是相当棘手的。

你做了一些调查，根据我的信息，WebTicket 应该是 UCWA 的一个可能的身份验证令牌。

不幸的是，文档仍然正确地说 UCWA 目前仅支持本地安装。对于 Lync Online/Office 365，它尚未启用。

Office 的用户语音上有一个功能请求，您可以投票和关注。如您所见，预计很快会有公告

看起来 Office 365 至少公开了 UCWA 功能的一个不错的子集。Lync Connectivity Analyzer 实际上是一个 .NET 应用程序，因此直接利用它来完成繁重的工作并不难。它不如使用“友好”库那么好，但在我的各种原型设计中它对我来说效果很好。使用下面的代码，我可以获取网络票值和 UCWA 基本 URL（通过自动发现），然后去城镇查询 API。这不是最漂亮的代码，但它可以工作。

注意：您需要在 Lync 连接分析器中添加对托管 DLL 的引用。对我来说，这意味着：

  • Credentials.dll
  • LyncConnectivityAnalyzer.Logging.dll
  • LyncConnectivityAnalyzer.Resources.dll
  • LyncWebServices.dll
  • Utilities.dll

您还需要将非托管 DLL（可能只有一个，但我两个都做了）复制到与您的应用程序相同的文件夹（例如\bin\文件夹）。
