手工处理的肥皂发送-XmlNode：NodeTypes和Attributes只读

编程问答 2022-04-26

问题描述

|| 我必须打电话给网络服务，但要手动构建xml。我选择了System.Xml来执行此操作，但这使我很痛苦。 我知道的每个SOAP都包含3个部分： XmlDeclaration 信封或SOAP-ENV：Envelope的标题 的 信封的主体或 SOAP-ENV：正文 问题是我的XmlDocument只能包含一个根元素。 （不知道为什么） 如果我做 
MyXMLDoc.CreateNode(XmlNodeType.DocumentFragment,\"SOAP-ENV\",\"Envelope\",\"http://tempuri.org\");
它不允许我附加属性。它说那些是只读的。 继续： 我必须怎么做才能编写此代码，但没有根目录并带有XmlDeclaration？以及如何调用Web服务（带有此xml）？

解决方法

        对于您的特定问题：在SOAP信封中，Body元素必须是Envelope的子元素。您不能让信封成为一个空元素，而其后的正文是。下面的代码显示了如何在XmlDocument对象中加载此文档的修改版本。 
    public class StackOverflow_6157636_751090
    {
        public static void Test()
        {
            string xml = @\"  <SOAP-ENV:Envelope xmlns:SOAP-ENV=\"\"http://schemas.xmlsoap.org/soap/envelope/\"\" xmlns:xsi=\"\"http://www.w3.org/2001/XMLSchema-instance\"\" xmlns:xs=\"\"http://www.w3.org/2001/XMLSchema\"\"> 
 <SOAP-ENV:Body>
 <ZbcInsertRequest xmlns:ns1=\"\"urn:sap-com:document:sap:soap:functions:mc-style\"\">
  <Destino>qas</Destino> 
 <IClrQst>
  <Request>foo</Request> 
  <Proyecto>foofoo</Proyecto> 
  <Modulocq /> 
  <Titureq>foofoofoo</Titureq> 
  <Tiporeq /> 
  <Prioridad>0</Prioridad> 
  <Clasific /> 
  <Asignadoa>foofoofoofoo</Asignadoa> 
  <Destino>qas</Destino> 
  <Solicita>foo</Solicita> 
  <Autoriza>c.foo</Autoriza> 
  <ModTransp /> 
  <ReqSox>F</ReqSox> 
  <Notfylst /> 
  <Tipodeploy>Normal</Tipodeploy> 
  <Paqdeploy>CDVQA00000000</Paqdeploy> 
  </IClrQst>
 <TRequest>
 <item>
  <Trkorr>DESK9A0ZJT</Trkorr> 
  <Secuencia>0</Secuencia> 
  <Solicita>c.foo</Solicita> 
  <Type /> 
  <Id /> 
  <Numero /> 
  <Message /> 
  </item>
  </TRequest>
  </ZbcInsertRequest>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>\";
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);
            MemoryStream ms = new MemoryStream();
            Encoding encoding = new UTF8Encoding(false);
            XmlWriter w = XmlWriter.Create(ms,new XmlWriterSettings { Indent = true,OmitXmlDeclaration = false,Encoding = encoding,IndentChars = \"  \" });
            doc.Save(w);
            w.Flush();
            Console.WriteLine(encoding.GetString(ms.ToArray()));
        }
    }
现在，您可以考虑（如果可能）的另一种选择不是“手动”发送SOAP请求，而是使用某种工具（例如WCF或其他SOAP库）创建代理，您可以使用该代理将请求发送到服务。这样，您的客户端可以简单地“调用方法”，并且堆栈将为您创建SOAP信封。
