Question

我正在寻找比这个答案中给出的更多细节：Exchange EWS not returning message body for calendar

具体来说，我不确定如何在查询中获取日历消息的正文。

我的XML查询是：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <m:FindItem Traversal="Shallow" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
            <m:ItemShape>
                <t:BaseShape>IdOnly</t:BaseShape>
                <t:AdditionalProperties>
                    <t:FieldURI FieldURI="item:Body"/>
                    <t:FieldURI FieldURI="calendar:Start"/>
                    <t:FieldURI FieldURI="calendar:End"/>
                    <t:FieldURI FieldURI="calendar:Location"/>
                    <t:FieldURI FieldURI="item:Attachments"/>
                </t:AdditionalProperties>
            </m:ItemShape>
            <m:CalendarView EndDate="2016-07-08T00:00:00Z" MaxEntriesReturned="999999" StartDate="2016-07-07T00:00:00Z"/>
            <m:ParentFolderIds>
                <t:DistinguishedFolderId Id="calendar"/>
            </m:ParentFolderIds>
        </m:FindItem>
    </s:Body>
</s:Envelope>

但我似乎收到了错误：

<t:FieldURI FieldURI="item:Body"/>

我已经查看了API：

https://msdn.microsoft.com/en-us/library/office/aa494315(v=exchg.150).aspx

而且我认为我必须遗漏一些简单的事情。有没有办法使用特定的基于字段的查询来获取日历正文？

由于

Answer 1

FindItem操作不会返回Body，Attendees和其他复杂/大型属性，请参阅https://blogs.msdn.microsoft.com/vikas/2007/07/26/ews-why-does-not-finditem-return-all-the-fields-you-expected/。

因此，您需要从FindItem请求中获取ItemId，然后创建单个GetItem请求https://msdn.microsoft.com/en-us/library/office/aa564509(v=exchg.150).aspx，或者如果您需要多个项目，请将GetItem请求一起批处理以提高效率。
