我正在使用第三方 Web 服务,该服务返回一个带有使用 MTOM 编码附加的 PDF 的对象。
该对象的结构Data[]
与每个具有字段ContentType
和的数组元素一样Include
。
当我运行 Web 服务方法时,它可以很好地完成请求,但是由于 Include 字段被解析为null
.
当我运行 Fiddler 时,我实际上可以看到远程 Web 服务返回包含所有可用字段的响应。
这是 SOAP 中发送的内容:
<m:GetDocImageResponse>
<x:data>
<x:item xmime5:contentType="*/*">
<xop:Include href="cid:id1"/></x:item>
</x:data>
</m:GetDocImageResponse>
我看到Include
有一个名为的属性href
,它包含对二进制 PDF 文档的引用。
我正在尝试根据 WSDL 解析对象:
Data[] retObject = null;
using (blahWS ws = new blahWS())
{
try{
retObject = ws.GetDoc(parameters); //request completes with no errors, but `Include` is parse as null
[...]
}
catch
{..}
}
Web 服务参考与一个简单的basicHttpBinding
<basicHttpBinding>
<binding name="BasicHTTPwithMTOM" messageEncoding="Mtom" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" textEncoding="utf-8" />
</basicHttpBinding>
我应该以不同的方式解析响应吗?为什么不解析字段?
