gSoap EWS“错误 500：内部服务器错误”

我在使用 ews(gSoap) 时遇到一些问题。

我有下一个代码：

ExchangeServiceBindingProxy *proxy = new ExchangeServiceBindingProxy(endpoint.c_str());

soap *pSoap = proxy->soap;
pSoap->userid = "Ivan1";
pSoap->passwd = "1";
pSoap->ntlm_challenge = "";
pSoap->authrealm = "Ursa-Minor";

pSoap->ssl_flags = SOAP_SSL_NO_AUTHENTICATION;
pSoap->keep_alive = true;   
pSoap->mode = SOAP_IO_KEEPALIVE;

//get root folder ID
ns3__DistinguishedFolderIdType *dfit = new ns3__DistinguishedFolderIdType();
dfit->Id = ns3__DistinguishedFolderIdNameType__inbox;

//set the props that we want to retrieve
ns3__FolderResponseShapeType *frst = new ns3__FolderResponseShapeType();
frst->BaseShape = ns3__DefaultShapeNamesType__AllProperties;

//get folder
ns1__GetFolderType *gftRoot = new ns1__GetFolderType();
gftRoot->FolderIds = new ns3__NonEmptyArrayOfBaseFolderIdsType();
gftRoot->FolderIds->__size_NonEmptyArrayOfBaseFolderIdsType = 1;
gftRoot->FolderIds->__union_NonEmptyArrayOfBaseFolderIdsType = new __ns3__union_NonEmptyArrayOfBaseFolderIdsType();
gftRoot->FolderIds->__union_NonEmptyArrayOfBaseFolderIdsType->union_NonEmptyArrayOfBaseFolderIdsType.DistinguishedFolderId = dfit;
gftRoot->FolderIds = (ns3__NonEmptyArrayOfBaseFolderIdsType*)dfit;
gftRoot->FolderShape = frst;
__ns1__GetFolderResponse response;

int ret = proxy->GetFolder(gftRoot, response);

我正在使用 OpenSSL 和 NTLM 库（WITH_OPENSSL、WITH_NTLM）。

结果 gSoap 生成了这个 SOAP：

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

<ns1:FolderIds Id="inbox" xsi:type="ns3:DistinguishedFolderIdType"> </ns1:FolderIds>
</ns1:GetFolder>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

服务器响应：

正如你所看到的，问题出在线上

<ns1:FolderIds Id="inbox" xsi:type="ns3:DistinguishedFolderIdType"

服务器不希望在这一行中看到 xsi:type="ns3:DistinguishedFolderIdType"。在原始 SOAP 中，它看起来像：

 <FolderIds>
  <DistinguishedFolderId Id="inbox" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" /> 
  </FolderIds>

所以。如何解决这个问题呢？

IStar,

首先，我不熟悉 gSOAP，也不熟悉这种语法。事实上，我并不指望回答你的问题，但我会尝试一下。尽管如此，gSOAP 正在尝试创建 EWS 不支持的 XML。我认为以下几行是不正确的，可能还需要一两行：

gftRoot->FolderIds->__union_NonEmptyArrayOfBaseFolderIdsType->union_NonEmptyArrayOfBaseFolderIdsType.DistinguishedFolderId = dfit;
gftRoot->FolderIds = (ns3__NonEmptyArrayOfBaseFolderIdsType*)dfit;

我认为第二行是指示 gSOAP 将FolderIds 元素设置为不应该的元素。看起来FolderIds 和DistinguishedFolderId 元素结构存在某种合并。

也许它应该看起来像这样：

ns3__NonEmptyArrayOfBaseFolderIdsType *fids = new ns3__NonEmptyArrayOfBaseFolderIdsType();
fids->DistinguishedFolderId = dfit
fids->__size_NonEmptyArrayOfBaseFolderIdsType = 1;
gftRoot->FolderIds = fids;
