Android 如何通过ksoap2创建SOAP请求 000D6F0000

我在一个android项目中工作，我想使用一些JAX-WS。这些服务是由其他人提供的，所以我不能对它们进行任何更改。我想用这些编写的代码发送上面的SOAP消息，但调用它们时我收到的唯一消息是java.lang.NullPointerException

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Header/>
    <S:Body>
        <ns2:FReadStatus xmlns:ns2="http://poweb13/">
            <arg0>000D6F0000</arg0>
        </ns2:FReadStatus>
    </S:Body>
</S:Envelope>

private静态最终字符串命名空间=”http://poweb13/";
私有静态最终字符串URL=”http://smart.gr:8080/aWESoME/SmartPlugService?wsdl"; 
私有静态最终字符串SOAP\u ACTION=“SmartPlugService”；
私有静态最终字符串方法\u NAME=“FReadStatus”；
SoapObject请求=新的SoapObject（名称空间、方法名称）；
PropertyInfo p1=新的PropertyInfo（）；
p1.设置名称（“MAC”）；
p1.设定值（“000D6F0000”）；
p1.setType（myDevice.getmac（）.toString（）.getClass（））；
请求。添加属性（p1）；
SoapSerializationEnvelope=新的SoapSerializationEnvelope（SoapEnvelope.VER11）；
envelope.setOutputSoapObject（请求）；
HttpTransportSE androidHttpTransport=新的HttpTransportSE（URL）；
试试{
androidHttpTransport.setXmlVersionTag（“”）；
调用（SOAP_操作，信封）；
SoapObject resultsRequestSOAP=（SoapObject）envelope.bodyIn；
字符串结果=resultsRequestSOAP.getProperty（“返回”）.toString（）；
Log.i（“信息”，“收到：+结果”）；
}catch（java.lang.ClassCastException e）{
SoapFault故障=（SoapFault）envelope.bodyIn；
Log.e（“error”，“Received:”+fault.getMessage（）.toString（））；
Log.e（“error”，“Received:”+fault.getLocalizedMessage（）.toString（））；
StackTraceElement[]st=fault.getStackTrace（）；
对于（int i=0；iOk），你有一个函数FReadStatus：

SOAP Response

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
    <S:Body>
        <ns2:FReadStatusResponse xmlns:ns2="http://poweb13/">
            <return>1</return>
        </ns2:FReadStatusResponse>
    </S:Body>
</S:Envelope>

现在您拥有了该类，您将在您拥有的代码中执行以下操作：

public class FReadStatus implements KvmSerializable {

String mac; 

@Override
public Object getProperty(int arg0) {
switch (arg0){
    case 0:
        return mac;
    default:
        return null;
        }
}

@Override
public int getPropertyCount() {
    return 1;//because you have 1 parameter
}

@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch(arg0)
{

    case 0:
        arg2.type = PropertyInfo.STRING_CLASS;//because its type is string
        arg2.name = "arg0";
        break;
    default:break;
}

}

@Override
public void setProperty(int arg0, Object arg1) {
switch(arg0)
{
    case 0:
        mac=  (String)arg1;
        break;
    default:
        break;
}
}

让我知道wt的发生。您必须使用来检查requestDump和responseDump

可能的原因和解决方案


检查您的AndroidManifest.xml中是否有：

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    PropertyInfo pi = new PropertyInfo();
    pi.setName("arg0");
    pi.setValue("000D6F0000");
    pi.setType(FReadStatus .class);
    request.addProperty(pi);

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

     //Now you have to add mapping to map the local class created, to the one on the server
    envelope.addMapping(NAMESPACE , FReadStatus.class.getSimpleName(), FReadStatus .class);

    // Add marshalling (this one might not be necessary, but ill just add it)
    Marshal floatMarshal = new MarshalFloat();
    floatMarshal.register(envelope);

    AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);//AndroidHttpTransport INSTEAD OF HttpTransportSE 

    androidHttpTransport.debug = true;//NEW ADDED
    try {           

        androidHttpTransport.call(SOAP_ACTION, envelope);

       //Important Outputs to check how the request/Response looks like.. Check them in Logcat to find these outputs
       System.out.println("requestDump is :"+androidHttpTransport.requestDump);
       System.out.println("responseDump is :"+androidHttpTransport.responseDump);
       System.out.println("response"+envelope.getResponse());

    } catch (Exception e){}
