EWS 操作 - 获取会议的与会者答案

【问题描述】：

使用EWS operations 到目前为止，我能够在一个时间范围内获得所有会议。如何获得会议的与会者？

我已阅读here，我可以发送带有会议 ID 的附加请求，以获得附加属性 (LoadPropertiesForItem)。

对应的SOAP操作是什么？

谢谢

private String getXMLRequestForRetrieve( DateTime start, DateTime end, String meetingRoomEmailToQuery ){

【解决方案1】：

您需要发出 EWS GetItem 请求 https://msdn.microsoft.com/en-us/library/office/aa566013(v=exchg.150).aspx ，如果您尝试对多个项目执行此操作，则可以批处理 GetItem 请求以提高效率。

我用这个 SOAP 请求解决了：

    private String getXMLReqForMeetingProperties(String itemId, String changeKey) { 

        return ""+
            "<?xml version=\"1.0\" encoding=\"utf-8\"?>"+
            "<soap:Envelope "+
                "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" "+
                "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" "+
                "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" "+
                "xmlns:m=\"http://schemas.microsoft.com/exchange/services/2006/messages\" "+
                "xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\">"+
                "<soap:Header>"+
                   "<RequestServerVersion Version=\"Exchange2013\" "+
                    "xmlns=\"http://schemas.microsoft.com/exchange/services/2006/types\" soap:mustUnderstand=\"0\" />"+
                "</soap:Header>"+
                "<soap:Body>"+
                    "<m:GetItem Traversal=\"Shallow\">"+
                        "<m:ItemShape>"+
                            "<t:BaseShape>IdOnly</t:BaseShape>"+
                            "<t:AdditionalProperties>"+
                                "<t:FieldURI FieldURI=\"item:Subject\"></t:FieldURI>"+
                                // "<t:FieldURI FieldURI=\"item:Body\"></t:FieldURI>"+
                                "<t:FieldURI FieldURI=\"item:TextBody\"></t:FieldURI>"+
                            "</t:AdditionalProperties>"+
                        "</m:ItemShape>"+
                        "<m:ItemIds>"+
                            "<t:ItemId Id=\""+itemId+"\" ChangeKey=\""+changeKey+"\"></t:ItemId>"+
                        "</m:ItemIds>"+
                    "</m:GetItem>"+
                "</soap:Body>"+
            "</soap:Envelope>";
    }
