显示应用程序端点的照片 [英] Displaying a photo for an Application endpoint

问题描述

这是我的问题: 自3个月以来，我从事一个大型UCMA项目，现在我想添加一个小功能.

Here is my problem : I work on a big UCMA project since 3 month and now I would like to add a little feature.

我有很多ApplicationEndpoints可以动态添加，修改或删除，我希望每次创建ApplicationEndpoint时都指定一张图片，该图片将显示在Microsoft Lync上.

I have a lot of ApplicationEndpoints which can be added, modified or deleted dynamically and I would like, each time that I create an ApplicationEndpoint, to specify a picture which will be displayed on Microsoft Lync.

我已经有很多其他功能，但是我真的很想拥有这个功能.

I already have a lot of other functionnalities but I'd really like to have this one.

我搜索了几天，但没有找到任何东西，所以在告诉自己无法完成之前，我想问一下！

I searched for days but I didn't find anything so before telling myself that it can't be done, I wanted to ask !

有人知道这是否可能吗?在那种情况下，您能告诉我这样做的方法吗?

Does anyone know if that is possible ? In that case, could you show me the way to do it?

谢谢

推荐答案

迟到总比没有好，但是这可能会对某人有所帮助.

Better late than never, but this might help someone.

我不确定这对于应用程序端点是否可行，但是您可以确定为用户端点发布照片设置(我已经做到了，并且可以使用).可以在MSDN上找到有关发布状态的一些基本信息:

I'm not sure if this is possible for an application endpoint, but you can publish photo settings for a user endpoint for sure (I have done this and it works). Some basic info on publishing presence can be found on MSDN: Publishing Presence.

在LocalEndpoint.LocalOwnerPresence上完成发布状态信息(包括照片设置). UserEndpoint和ApplicationEndpoint都是从LocalEndpoint派生的，因此这应该确实可行.

Publishing presence information (which includes photo settings) is done on the LocalEndpoint.LocalOwnerPresence. Both UserEndpoint and ApplicationEndpoint derive from LocalEndpoint, so this should be doable really.

实际发布会变得有些复杂，因为要发布的级别"有很多不同的组合:

The actual publishing gets slightly complex because there are a lot of different combinations of 'levels' to publish on:

首先，您需要了解很多InstanceID值，请在此处进行阅读:

First, there are a bunch of InstanceID values that you need to know about, read up on them here: Presence data source and category instance ID

第二，存在此存在对象的值，请参见Microsoft.Rtc.Collaboration.Presence.PresenceRelationshipLevel.不要在Unknown上发布，您会遇到异常.

Second, there is a value for who this presence applies to, see Microsoft.Rtc.Collaboration.Presence.PresenceRelationshipLevel. Don't publish on Unknown, you'll get an exception.

public enum PresenceRelationshipLevel  
{  
    Unknown = -1,  
    Everyone = 0,  
    External = 100,  
    Colleagues = 200,  
    Workgroup = 300,  
    Personal = 400,  
    Blocked = 32000,  
}

您需要发布用户照片属性的PresenceCategoryWithMetaData，它是容器0x5状态信息"的一部分.

You need to publish a PresenceCategoryWithMetaData for the user photo properties, which is part of container 0x5, "Presentity information".

var photoPresence = new PresenceCategoryWithMetaData(
    0x5, // The container id
    (int)PresenceRelationshipLevel.Everyone,
    new ContactCard(0x5) // Same container ID again
    {
        IsAllowedToShowPhoto = true,
        PhotoUri = "<uri to your photo here"
    });

您也可以在该对象上设置一个ExpiryPolicy，确实应该是自解释的.然后将此状态对象发布到您的端点上:

You can set an ExpiryPolicy on this object too, should be self explainatory really. Then publish this presence object on your endpoint:

Endpoint.LocalOwnerPresence.BeginPublishPresence(new[] { photoPresence  }, cb => { 
    Endpoint.LocalOwnerPresence.EndPublishPresence(cb);
}, null);

这确实应该做到.我最终明确地发布了所有关系级别的内容，因为它没有按照逻辑上的预期层叠数据.这变成了一个冗长的答复，也供我自己将来参考.请让我知道这是否也适用于应用程序终结点.

And that should do it, really. I ended up explicitly publishing to all relationship levels because it didn't cascade the data as logically expected. This turned into quite a lengthy reply, also for my own future reference. Please let me know if this works for app endpoints too.
