我一直在挣扎了几个小时试图建立使用kso​​ap2为Android没有运气正确的SOAP请求。 理想的要求是这样的： 

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Header>
    <AuthorizationToken xmlns="http://www.avectra.com/2005/">
      <Token>string</Token>
    </AuthorizationToken>
  </soap:Header>
  <soap:Body>
    <ExecuteMethod xmlns="http://www.avectra.com/2005/">
      <serviceName>string</serviceName>
      <methodName>string</methodName>
      <parameters>
        <Parameter>
          <Name>string</Name>
          <Value>string</Value>
        </Parameter>
      </parameters>
    </ExecuteMethod>
  </soap:Body>
</soap:Envelope>

我使用下面的代码生成我的要求： 

    SoapObject request = new SoapObject(NAMESPACE, METHOD);
    request.addProperty("serviceName", SERVICENAME);
    request.addProperty("methodName", METHODNAME);

    SoapObject nestedParameters = new SoapObject(NAMESPACE, "parameters");
    SoapObject param = new SoapObject(NAMESPACE, "Parameter");
    param.addProperty("Name", name);
    param.addProperty("Value", value);
    nestedParameters.addSoapObject(param);
    request.addSoapObject(nestedParameters);

    SoapSerializationEnvelope envelope = 
            new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.setOutputSoapObject(request);
    envelope.dotNet = true;
    envelope.implicitTypes = true;

    envelope.headerOut = new Element[1];
    Element header = new Element().createElement(NAMESPACE, "AuthorizationToken");
    Element token = new Element().createElement(NAMESPACE, "Token");
    token.addChild(Node.TEXT, this.AUTH_TOKEN);
    header.addChild(Node.ELEMENT, token);
    envelope.headerOut[0] = header;

什么ksoap2是建筑是： 

<v:Envelope xmlns:i="http://www.w3.org/1999/XMLSchema-instance" xmlns:d="http://www.w3.org/1999/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
  <v:Header>
    <n0:AuthorizationToken xmlns:n0="http://www.avectra.com/2005/">
      <n0:Token>string</n0:Token>
    </n0:AuthorizationToken>
  </v:Header>
  <v:Body>
    <ExecuteMethod xmlns="http://www.avectra.com/2005/" id="o0" c:root="1">   
      <serviceName>AHAWebServices</serviceName>
      <methodName>MemberDirectory</methodName>
      <parameters i:type="n1:parameters" xmlns:n1="http://www.avectra.com/2005/">
        <Parameter i:type="n1:Parameter">
          <Name>string</Name>
          <Value>string</Value>
        </Parameter>
      </parameters>
    </ExecuteMethod>
  </v:Body>
</v:Envelope>

我有一种感觉，这个问题是与N0前缀的头，但我不知道如何摆脱他们。 我删除它们从身体通过设置implicitTypes为真，但我找不到头类似的设置。 我是新来的SOAP，因此任何其他意见是极大的赞赏。 有没有人有，我怎么能解决这个问题的想法？

Answer 1:

当使用KSOAP这为我工作 

SoapObject request = new SoapObject(WEBSERVICE_NAMESPACE, methodName);
    if(null != parameterMap && !parameterMap.isEmpty()){
        for(Entry<String, String> entry: parameterMap.entrySet()){
            request.addProperty(entry.getKey(), entry.getValue());
        }
    }
    // Declare the version of the SOAP request

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.implicitTypes = true;
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);


    HttpTransportSE androidHttpTransport = new HttpTransportSE(ApplicationConstants.WEBSERVICE_WSDL_URL);

    // this is the actual part that will call the webservice
    try {

        androidHttpTransport.debug = true;
        androidHttpTransport.call(soapActionUrl, envelope);
        String ss = androidHttpTransport.responseDump;

        // Get the SoapResult from the envelope body.

        Log.d(TAG, "request: " + androidHttpTransport.requestDump);
        Log.d(TAG, "response: "+    androidHttpTransport.responseDump);


        SoapObject result = (SoapObject) envelope.getResponse();

        Log.d("soap response", "" + result);            
    } catch (IOException e) {
        Log.e(TAG, "IOException", e);
    }

注意： 

androidHttpTransport.debug = true;

解决了我的情况的问题。 拍着我的头，但不能用，为什么设置调试真正帮助解决问题原因。

为什么你需要使用KSOAP？ 只要有你的SOAP请求字符串的静态党，值追加到静态部分，你终于可以有完整的SOAP请求。 最后，使用HTTP方法来发送POST请求。

无需额外的JAR

此外KSOAP有一个像OOM大型响应等问题

}


Answer 2:

我想你需要另一种方式来创建头，它看起来像JAX-WS，所以我会用JAX WS实现我几个月前做去。

首先你需要一个HeaderHandler类至极创建SOAP头元素，它应该是这样的： 

    import javax.xml.namespace.QName;
    import javax.xml.soap.SOAPElement;
    import javax.xml.soap.SOAPEnvelope;
    import javax.xml.soap.SOAPHeader;
    import javax.xml.ws.handler.MessageContext;
    import javax.xml.ws.handler.soap.SOAPHandler;
    import javax.xml.ws.handler.soap.SOAPMessageContext;


    public class HeaderHandler implements SOAPHandler<SOAPMessageContext> {

        public boolean handleMessage(SOAPMessageContext smc) {
            Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
            String AUTH_TK = "http://www.avectra.com/2005/";
            String PREFIX="";//no prefix
            String PREFIX_XMLNS="xmlns";
            String value =  "123456";
            if (outboundProperty.booleanValue()) {
                try {
                    SOAPEnvelope envelope = smc.getMessage().getSOAPPart().getEnvelope();
                    SOAPHeader header = envelope.addHeader();
                    //<AuthorizationToken xmlns="http://www.avectra.com/2005/">
                    SOAPElement authorizationToken = header.addChildElement("AuthorizationToken", PREFIX_XMLNS, AUTH_TK);
                    //<Token>value</Token>
                    SOAPElement usernameToken =
                        authorizationToken.addChildElement("Token", PREFIX);
                        usernameToken.addTextNode(value);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            return outboundProperty;
        }


        public Set<QName> getHeaders() {
            return null;
        }

        public void close(MessageContext arg0) {

        }

        public boolean handleFault(SOAPMessageContext arg0) {
            return false;
        }
    }

之后，你创建一个HeaderHandlerResolver处理头的创建和处理程序链插入： 

    import java.util.ArrayList;
    import java.util.List;
    import javax.xml.ws.handler.Handler;
    import javax.xml.ws.handler.HandlerResolver;
    import javax.xml.ws.handler.PortInfo;

    public class HeaderHandlerResolver implements HandlerResolver {

    @SuppressWarnings("unchecked")
    public List<Handler> getHandlerChain(PortInfo portInfo) {
          List<Handler> handlerChain = new ArrayList<Handler>();
          HeaderHandler hh = new HeaderHandler();
          handlerChain.add(hh);
          return handlerChain;
       }
    }

在此之后，您在客户端添加： 

        try{
            //new service instance (your service should be extending javax.xml.ws.Service;)
            YourServiceProxy service = new YourServiceProxy();
            //calls the header handler resolver ;)
            service.setHandlerResolver(new HeaderHandlerResolver());
            //get the service
            YourService port = (YourService)service.getYourService();
            //call the service 
            port.yourMethod()   
        } catch (Exception e) {
            e.printStackTrace();
        }

顺便说一句，我没有测试过这个特别的头，我修改了一个头处理程序我有，所以它可能是不准确的，但我认为这是非常密切的，我真的希望它可以帮助你，尝试一下，告诉我们如何它来了，我会尽力帮助你，如果还不行的作品。



Answer 3:

你检查通过KSOAP用于生成的类型是否parameters （即i:type="n1:parameters" ）和Parameter （即i:type="n1:Parameter" ）节点是正确的（它们是在WSDL定义）？

尝试设置

envelope.implicitTypes = true;

而且还玩

envelope.setAddAdornments(false);

强制KSOAP不包括type属性和名称空间。



Answer 4:

组

 envelope.implicitTypes = true;

并且不设置

 envelope.setAddAdornments(false)

这为我工作。
