Exchange 2007 ews（Web 服务） - 找出谁已同意参加会议？

Question

我是使用 Exchange EWS 的新手，无法在文档或在线找到任何对此的参考。

我正在连接到我的 Exchange 2007 服务器并使用 PHP SoapClient 检索给定帐户的日历会议列表。这是有效的，正在检索所有会议作为 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接受参加会议。我收集到 CalendarItem 对象的 DisplayTo 属性告诉我们谁被邀请了，但肯定有些人可能拒绝了。那么，如果我想知道谁会实际到场，我该如何获得这些信息？

这似乎是提供有用的信息（例如计划餐饮或其他），因此它似乎不太可能不会通过网络服务公开，但我不知道如何发现这些信息。

谁能帮忙？

编辑：只是为了澄清 Exchange 2007 Web 服务返回的内容，这是该服务为每次会议返回的内容：

Answer 1

您可以循环访问约会中的参与者并检查他们的响应类型。我已经为您编写了一个扩展的代码块来帮助您理解。我希望这会有所帮助:)

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++;
        }
    }
}

Answer 2

这个答案是一个暂定的解决方案，但据我所知，它似乎有效。

因此，要使用 PHP SOAPClient 形成 SOAP 请求以获取每个约会的约会详细信息，如原始问题所示，我使用以下内容：

//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;
}

但是，您似乎只能查看您所连接的帐户作为组织者的会议请求的 ResponseType。所有其他会议都显示为“未知”作为 ResponseType。

您需要计算 MeetingResponseType 为 Accept 的与会者人数。请参阅此类似帖子：Count the number of attendees, that have accepted a meeting with EWS。
