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：

I have been struggling for hours trying to build the correct SOAP request using ksoap2 for Android with no luck. The ideal request looks like this:

<?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code生成我的要求：

I am using the following code to generate my request:

    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正在建设的是：

What ksoap2 is building is:

<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 prefixes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所以任何其他的建议是极大的AP preciated。任何人都不会有的，我怎么能解决这个问题的想法？

I have a feeling that the problem is in the header with the n0 prefixes but I have no clue how to get rid of them. I removed them from from the body by setting implicitTypes to true but I cannot find a similar setting for the header. I am new to SOAP so any other advice is greatly appreciated. Does anyone have an idea of how I could fix this?

推荐答案

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);
    } 

请注意：

androidHttpTransport.debug = true;

在我的情况下解决了问题。拍着我的头，但不能讲理，为什么设置调试真正帮助解决问题。

resolved the issue in my case. Banged my head but could not reason with why setting debug true helped resolve the issue.

为什么需要使用KSOAP？ 只要有一个字符串的SOAP请求的静态方，追加值的静态部分，你终于可以有完整的SOAP请求。最后，使用HTTP方法来发送你的post请求。

Why do you need to use ksoap? Simply have the static party of your SOAP request as a String, append the values to the static part and you can finally have the complete SOAP request. Finally use HTTP methods to send your post request.

没有额外的JAR

此外KSOAP有一个像OOM对于大响应等问题

Also ksoap has issues like OOM for large responses, etc.
