如何通过ksoap2创建SOAP请求

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

    </S:Body> 
</S:Envelope>

我在一个Android项目中工作，我想要使用一些JAX-WS。该服务是由别人做，所以我不能改变他们。我的东西要与这个编写的代码，但我收到的时候打电话给他们的唯一的事情来发送上述SOAP消息是显示java.lang.NullPointerException如何通过ksoap2创建SOAP请求

private static final String NAMESPACE = "http://poweb13/"; 
private static final String URL = "http://smart.gr:8080/aWESoME/SmartPlugService?wsdl"; 
private static final String SOAP_ACTION = "SmartPlugService"; 
private static final String METHOD_NAME = "FReadStatus"; 
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
PropertyInfo p1 = new PropertyInfo(); 
p1.setName("MAC"); 
p1.setValue("000D6F0000"); 
p1.setType(myDevice.getmac().toString().getClass()); 
request.addProperty(p1); 
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
envelope.setOutputSoapObject(request); 
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
try {   
    androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");     
    androidHttpTransport.call(SOAP_ACTION, envelope); 
    SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; 
    String result=resultsRequestSOAP.getProperty("return").toString(); 
    Log.i("info","Received :" + result); 
} catch (java.lang.ClassCastException e){ 
    SoapFault fault=(SoapFault)envelope.bodyIn; 
    Log.e("error","Received :" + fault.getMessage().toString()); 
    Log.e("error","Received :" + fault.getLocalizedMessage().toString()); 
    StackTraceElement[] st=fault.getStackTrace(); 
    for(int i=0;i<st.length;i++){ 
     Log.e("error","Received :" +st[i]); 
    } 
} catch (Exception e) { 
    Log.e("error","smthing went wrong!!"); 
    e.printStackTrace(); 
}

我认为它甚至不会创建xml文档，但我不知道如何检查它。我试图创建一个XmlSerializer来创建XML的数据，但我也收到一个NullPointerException。那么任何人都可以帮助我了解如何编码上述请求？这里的WSDL文件的某些部分

XSD文件的

<xs:complexType name="FReadStatus">

我应该有一个这样的SOAP响应某些部分：

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>

好了，所以你有一个函数FReadStatus：

<message name="FReadStatus"> 
    <part name="parameters" element="tns:FReadStatus"/> 
</message>

它有一个元素FReadStatus复杂类型（即对象，它是在服务器上找到的类）。
此复杂类型具有String类型的属性arg0。它的定义是：

<xs:complexType name="FReadStatus"> 
    <xs:sequence> 
    <xs:element name="arg0" type="xs:string" minOccurs="0"/> 
    </xs:sequence> 
</xs:complexType>

所以，你需要创建一个实现kvmSerializable这种复杂类型映射到服务器上的相应类别的本地类，所以你会做什么：

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; 
} 
}

现在，你有这个类，你会做你有以下代码：

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){}

让我知道发生了重量。您必须使用Logcat检查requestDump和responseDump

UPDATE：回答你的问题有关UnknowHostException
可能的原因和解决方法

检查在AndroidManifest.xml中你有：

<uses-permission android:name="android.permission.INTERNET" />

如果您正在使用仿真器，请按照link

如果你使用了代理做：

System.setProperty("http.proxyHost", "my.proxyhost.com"); 
System.setProperty("http.proxyPort", "1234");

您可能需要预热的DNS使用，请在此link
