Exchange web services - find all unread messages with soap xml request

问题

在我的应用程序中，我需要查询Exchange Web Services服务器并找到所有未读消息。我正在使用Golang发送SOAP XML请求。我尝试了以下代码：

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  3.     xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"
  4.     xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"
  5.     xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  6.     <soap:Header>
  7.         <t:RequestServerVersion Version="Exchange2013_SP1" />
  8.     </soap:Header>
  9.     <soap:Body>
  10.         <m:FindItem
  11.             Traversal="Shallow">
  12.             <m:ItemShape>
  13.                 <t:BaseShape>IdOnly</t:BaseShape>
  14.             </m:ItemShape>
  15.             <m:Restriction>
  16.                 <t:IsEqualTo>
  17.                     <t:FieldURI FieldURI="item:IsRead" />
  18.                     <t:FieldURIOrConstant>
  19.                         <t:Constant Value="false" />
  20.                     </t:FieldURIOrConstant>
  21.                 </t:IsEqualTo>
  22.             </m:Restriction>
  23.             <m:ParentFolderIds>
  24.                 <t:DistinguishedFolderId Id="inbox" />
  25.             </m:ParentFolderIds>
  26.         </m:FindItem>
  27.     </soap:Body>
  28. </soap:Envelope>

但是在这种情况下，我收到错误消息说我的请求不正确。如果我删除<t:IsEqualTo>，我会得到收件箱中的所有消息。有什么办法可以修复这个问题吗？谢谢。

  16. <t:IsEqualTo>
  17. <t:FieldURI FieldURI="item:IsRead" />
  18. <t:FieldURIOrConstant>
  19. <t:Constant Value="false" />
  20. </t:FieldURIOrConstant>
  21. </t:IsEqualTo>
  22. </m:Restriction>
  23. <m:ParentFolderIds>
  24. <t:DistinguishedFolderId Id="inbox" />
  25. </m:ParentFolderIds>
  26. </m:FindItem>
  27. </soap:Body>
  28. </soap:Envelope>

but in this case I get error saying that my request is incorrect. If I remove <t:IsEqualTo>, I get all messages in my inbox. Any ideas how to fix it would be welcome. Thank you

根据FieldURI属性列表，item:IsRead应该是message:IsRead。以下是从在EWS中使用搜索过滤器中复制的示例：

  1. <t:IsEqualTo>
  2.   <t:FieldURI FieldURI="message:IsRead" />
  3.   <t:FieldURIOrConstant>
  4.     <t:Constant Value="false" />
  5.   </t:FieldURIOrConstant>
  6. </t:IsEqualTo>
英文:

According to the list of FieldURI Attribute, item:IsRead should be message:IsRead. Below is the example copied from Equality filter in EWS
:

  1. &lt;t:IsEqualTo&gt;
  2.   &lt;t:FieldURI FieldURI=&quot;message:IsRead&quot; /&gt;
  3.   &lt;t:FieldURIOrConstant&gt;
  4.     &lt;t:Constant Value=&quot;false&quot; /&gt;
  5.   &lt;/t:FieldURIOrConstant&gt;
  6. &lt;/t:IsEqualTo&gt;
