我正在尝试通过在以下代码中使用 C# XmlDocument 类来编写对 ebay FindingAPI Web 服务的 SOAP 请求:
XmlDocument doc = new XmlDocument();
XmlElement root = (XmlElement)doc.AppendChild(doc.CreateElement("soap", "Envelope", "http://www.w3.org/2003/05/soap-envelope"));
root.SetAttribute("xmlns", "http://www.ebay.com/marketplace/search/v1/services");
XmlElement header = (XmlElement)root.AppendChild(doc.CreateElement("soap", "Header", "http://www.w3.org/2003/05/soap-envelope"));
XmlElement body = (XmlElement)root.AppendChild(doc.CreateElement("soap", "Body", "http://www.w3.org/2003/05/soap-envelope"));
XmlElement request = (XmlElement)body.AppendChild(doc.CreateElement("findItemsByKeywordsRequest"));
XmlElement param = (XmlElement)request.AppendChild(doc.CreateElement("keywords"));
param.InnerText = "harry potter phoenix";
并且,上述代码的 XML 输出为:
<soap:Envelope xmlns="http://www.ebay.com/marketplace/search/v1/services" xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header />
<soap:Body>
<findItemsByKeywordsRequest xmlns="">
<keywords>harry potter phoenix</keywords>
</findItemsByKeywordsRequest>
</soap:Body>
</soap:Envelope>
但是,由于 findItemsByKeywordsRequest 元素中的额外 xmlns="" 属性,服务器无法识别此 XML。所需的 XML 输出应如下所示:
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns="http://www.ebay.com/marketplace/search/v1/services">
<soap:Header/>
<soap:Body>
<findItemsByKeywordsRequest>
<keywords>harry potter phoenix</keywords>
</findItemsByKeywordsRequest>
</soap:Body>
</soap:Envelope>
有谁知道我的代码有什么问题,请给我一些提示。谢谢!
