我有一个UCWA应用程序，我希望accept传入onlineMeetingInvitation事件，然后监控所有消息。虽然我已成功接受邀请，但我没有收到任何消息的事件。我相信这可能是因为默认情况下没有连接消息传递模式，所以我尝试addMessaging。不幸的是，此请求始终返回409错误和消息，
发生了冲突，阻止了操作的启动。请稍后再试。
有谁知道， 一个。如果尝试addMessaging是正确的？ 湾为什么我收到上述错误？
我在对话中设置了两个普通的Lync客户端。然后我邀请我的UCWA应用程序的用户加入对话。这会在我的事件频道上产生以下响应（包括按预期的接受链接）

同样，我相信这是预期的，此时原始Lync客户端按预期显示3个参与者。
接下来，我尝试对上面代码段中的addMessaging href进行POST。 POST没有正文。
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冲突，我没有收到两个Lync客户端添加到对话的新邮件的事件。

答案 0 :(得分：0)
您的问题似乎可以通过添加operationId来解决，即使在UCWA文档中已将其作为可选项提及。 根本原因可能是有关UCWA的microsoft文档的显示中存在一个可重现的错误：例如https://ucwa.skype.com/documentation/resources-startmessaging，用于选择API版本的下拉列表不可见。 仅在Mozilla Firefox中会发生此错误，并且在您的日志中看到它是您正在使用的版本（nb：我已经使用61版进行了测试）。 使用Chrome，它可以正确显示，并且您有时会看到operationID是强制性的（仅在某些版本的API上）。 您的服务器使用的API版本可以通过以下链接确定： https://docs.microsoft.com/en-us/skype-sdk/ucwa/versioning
我希望这可以帮助您解决UCWA的其他问题-无需使用试错法。
