Exchange 2007 ews（Web服務） - 找出誰已經接受參加會議？

Question

我是使用Exchange EWS的全新軟件，無法在文檔或在線中找到對此的任何參考。

我正在連接到Exchange 2007服務器，並使用PHP SoapClient檢索給定帳戶的日曆會議列表。這是工作，並檢索所有的會議作爲CalendarItem對象，然後我可以在我的PHP腳本中使用。

但是，我真正需要的是知道誰有接受出席會議。我收集了CalendarItem對象的DisplayTo屬性告訴我們哪些人被邀請，但肯定其中一些人可能已經拒絕。所以，如果我想知道誰將在那裏，我怎麼能得到這些信息？

這似乎是有用的信息可用（例如計劃餐飲或其他），所以它似乎不可能通過Web服務公開，但我無法找到如何發現此信息。

任何人都可以幫忙嗎？

編輯：只是爲了澄清什麼是由Exchange 2007 Web服務返回，這是什麼服務回報每一次會議：

Answer 1

這個答案是一個試探性的解決方案，但它似乎工作據我所知。

因此，使用PHP的SOAPClient以獲得每個約會的約會細節，形成SOAP請求，如在原來的問題，我用的是以下幾點：

//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，似乎就可以只查看會議請求的ResponseType，即您連接的帳戶是組織者。所有其他會議顯示爲「未知」作爲ResponseType。

Answer 2

你需要計算的是有一個MeetingResponseType出席人數的接受。看到類似的帖子：Count the number of attendees, that have accepted a meeting with EWS。

Answer 3

您可以循環約會中的與會者，並檢查其響應類型是什麼。我已經爲您編寫了一個擴展的代碼塊來幫助您理解。我希望這可以幫助:)

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++; 
     } 
    } 
}
