Exchange 2007 ews（Web服务） - 找出谁已经接受参加会议？

Question

我是使用Exchange EWS的全新软件，无法在文档或在线中找到对此的任何参考。

我正在连接到Exchange 2007服务器，并使用PHP SoapClient检索给定帐户的日历会议列表。这是工作，并检索所有的会议作为CalendarItem对象，然后我可以在我的PHP脚本中使用。

但是，我真正需要的是知道谁有接受出席会议。我收集了CalendarItem对象的DisplayTo属性告诉我们哪些人被邀请，但肯定其中一些人可能已经拒绝。所以，如果我想知道谁将在那里，我怎么能得到这些信息？

这似乎是有用的信息可用（例如计划餐饮或其他），所以它似乎不可能通过Web服务公开，但我无法找到如何发现此信息。

任何人都可以帮忙吗？

编辑：只是为了澄清什么是由Exchange 2007 Web服务返回，这是什么服务回报每一次会议：

Answer 1

这个答案是一个试探性的解决方案，但它似乎工作据我所知。

因此，使用PHP的SOAPClient以获得每个约会的约会细节，形成SOAP请求，如在原来的问题，我用的是以下几点：

//Loop through each CalendarItem in the CalendarItems collection 
//Using a "by reference" pointer as I want to add the extra information to the original object. 
foreach($calendaritems as &$b){ 
    $NewSearch->Traversal = "Shallow"; 
    $NewSearch->ItemShape->BaseShape = "AllProperties"; 
    $NewSearch->ItemIds->ItemId = $b->ItemId; 
    $result = $client->GetItem($NewSearch); 

    //add the RequiredAttendees element to the original calendar item, just for convenience 
    $b->RequiredAttendees = $result->ResponseMessages->GetItemResponseMessage->Items->CalendarItem->RequiredAttendees; 
} 

然而，似乎就可以只查看会议请求的ResponseType，即您连接的帐户是组织者。所有其他会议显示为“未知”作为ResponseType。

Answer 2

你需要计算的是有一个MeetingResponseType出席人数的接受。看到类似的帖子：Count the number of attendees, that have accepted a meeting with EWS。

Answer 3

您可以循环约会中的与会者，并检查其响应类型是什么。我已经为您编写了一个扩展的代码块来帮助您理解。我希望这可以帮助:)

Appointment existingAppointment; 

int acceptCount = 0; 

if (existingAppointment.RequiredAttendees.Count > 0) 
{ 
    foreach(Attendee att in existingAppointment.RequiredAttendees) 
    { 
     if ((att.ResponseType.HasValue) && (att.ResponseType.Value == MeetingResponseType.Accept)) 
     { 
      acceptCount++; 
     } 
    } 
}
