UCWA -接受传入的onlineMeetingInvitation

Question

摘要

我有一个UCWA应用程序，我希望它能够接受传入的onlineMeetingInvitation事件，然后监视所有消息。虽然我已经成功地接受了邀请，但我没有收到任何消息的事件。我相信这可能是因为在默认情况下消息传递模式没有连接，所以我尝试使用addMessaging。不幸的是，这个请求总是返回一个409错误和消息，

发生了一场冲突，使行动无法开始。请稍后再试。

有人知道，如果试图addMessaging是正确的吗？为什么我会收到上面的错误？

详细信息

我在谈话中设置了两个普通的Lync客户。然后，我邀请我的UCWA应用程序的用户参加对话。这将在我的事件通道上产生以下响应(包括预期的accept链接)

我在“接受”href上执行一个帖子，它成功地响应，没有任何内容。然后我收到两个事件响应，其中第二个包括以下内容

再次，我相信这是预期的，在这一点上，原来的Lync客户正在显示3名参与者的预期。

接下来，我尝试在上面的片段中对addMessaging href做一篇文章。这个职位没有身体。

​

URI         : https://xxx.xxx.xx/ucwa/oauth/v1/applications/102547331865/communication/messagingInvitations?conversation=0ae942e4-9133-4888-a0fb-8a7b182fff00
Method      : POST
Headers     : {Accept=[text/plain, application/json, application/*+json, */*], Content-Length=[0]}
Request body:

​

结果是409的冲突，我从来没有收到事件的新消息添加到对话的两个Lync客户端。

​

Header {Cache-Control=[no-cache], Pragma=[no-cache], Via=[1.1 DEVLYNC2.xxx.xxx.xx RtcInt], Content-Length=[120], Content-Type=[application/json], Expires=[-1], Server=[Microsoft-IIS/7.5], X-MS-Server-Fqdn=[DEVLYNC2.xxx.xx.xx], X-AspNet-Version=[4.0.30319], Strict-Transport-Security=[max-age=31536000; includeSubDomains], X-Powered-By=[ASP.NET], Date=[Fri, 28 Oct 2016 07:31:51 GMT]}

Body {"code":"Conflict","message":"There was a conflict that prevented the operation from starting. Please try again later."}

Answer 1

添加operationId似乎解决了您的问题，尽管UCWA文档中提到了它是可选的。根本原因可能是在显示有关UCWA的microsoft文档时存在一个可复制的错误:例如，https://ucwa.skype.com/documentation/resources-startmessaging，选择API版本的下拉列表是不可见的。这个错误只发生在上，我从您的日志中看到它是您使用的版本(nb :我用版本61进行了测试)。使用Chrome，它正确地显示，您可以看到operationID有时是强制性的(仅在某些版本的API上)。服务器使用的API版本可以从以下链接确定：https://learn.microsoft.com/en-us/skype-sdk/ucwa/versioning

我希望这可以帮助您解决进一步的问题与UCWA -不需要使用试错的方法。
