我是android的初学者，在这里我有使用web服务的活动：
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
GetBoundData val = new GetBoundData() {
};
PropertyInfo pi = new PropertyInfo();
pi.setName("GetBoundData");
pi.setValue(val);
pi.setType(GetBoundData.class);
request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
Marshal floatMarshal = new MarshalFloat();
envelope.addMapping(NAMESPACE, GetBoundData.class.getSimpleName(), GetBoundData.class);
floatMarshal.register(envelope);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug =true;
TextView t = (TextView)this.findViewById(R.id.resultbox);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
System.out.println("aht requestDump is :"+androidHttpTransport.requestDump);
System.out.println("aht responseDump is :"+androidHttpTransport.responseDump);
} catch (Exception e) {
e.printStackTrace();
}
try {
Object result = (Object) envelope.bodyIn;
String s = result.toString();
t.setText(s);
} catch (ClassCastException e) {
// TODO Auto-generated catch block
e.printStackTrace();
t.setText("1");
}
并在GetBoundData类中：
public abstract class GetBoundData implements KvmSerializable {
String Bound = "((-0.00021792948245596397, -0.0002648681402206421), (0.00021792948246868618, 0.0002648681402206421))";
String Zoom ="21";
public Object getProperty(int arg0) {
switch (arg0){
case 0:
return Bound;
case 1:
return Zoom;
default:
return null;
}
}
public int getPropertyCount() {
return 2;//because you have 2 parameters
}
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch(arg0)
{
case 0:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Bound";
break;
case 1:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Zoom";
break;
default:break;
}
}
public void setval(String bound, String zoom) {
Bound = bound;
Zoom = zoom;
}
public void setProperty(int arg0, Object arg1) {
switch(arg0)
{
case 0:
Bound = (String)arg1;
break;
case 1:
Zoom = (String)arg1;
break;
default:
break;
}
} }
这是webservice xml
<wsdl:types>
<s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
<s:element name="GetBoundData">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Bound" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Zoom" type="s:string"/>
</s:sequence>
</s:complexType>
</s:element>
<s:element name="GetBoundDataResponse">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="GetBoundDataResult" type="tns:ArrayOfAnyType"/>
</s:sequence>
</s:complexType>
</s:element>
<s:complexType name="ArrayOfAnyType">
<s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="anyType" nillable="true"/>
</s:sequence>
</s:complexType>
</s:schema>
</wsdl:types>
这里是webservice示例：
请求：
<?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:Body>
<GetBoundData xmlns="http://tempuri.org/">
<Bound>string</Bound>
<Zoom>string</Zoom>
</GetBoundData>
</soap:Body>
</soap:Envelope>
响应：
<?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:Body>
<GetBoundDataResponse xmlns="http://tempuri.org/">
<GetBoundDataResult>
<anyType />
<anyType />
</GetBoundDataResult>
</GetBoundDataResponse>
</soap:Body>
</soap:Envelope>
但要显示：
SoapFault - faultcode: 'soap:Server'
faultstring: 'Server was unable to process request. ---> Object reference not set to an
instance of an object.' faultactor: 'null' detail: org.kxml2.kdom.Node@44efb360
我使用soapobject和getresponse（）但发生了错误
答案 0 :(得分：2)
多数民众赞成因为你有复杂的类型（即对象）而你只是添加＆＃34;简单类型＆＃34;属性。
检查我的回答here，我详细解释了需要做什么
您还必须创建与复杂类型匹配的本地类，这些本地类应实现kvmserializable，例如：
<s:element name="GetBoundData">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Bound" type="s:string"/>
<s:element minOccurs="0" maxOccurs="1" name="Zoom" type="s:string"/>
</s:sequence>
</s:complexType>
表示在Web服务上，存在一个名为＆＃34; GetBoundData＆＃34;的类。因此，自从使用ksoap2手动构建soap信封后，您必须在应用程序中创建这样的类，实现kvmserializable（这是一个ksoap2序列化接口）：
public class GetBoundData implements KvmSerializable {
String Bound;
String Zoom;
@Override
public Object getProperty(int arg0) {
switch (arg0){
case 0:
return Bound;
case 1:
return Zoom;
default:
return null;
}
}
@Override
public int getPropertyCount() {
return 2;//because you have 2 parameters
}
@Override
public void getPropertyInfo(int arg0, Hashtable arg1, PropertyInfo arg2) {
switch(arg0)
{
case 0:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Bound";
break;
case 1:
arg2.type = PropertyInfo.STRING_CLASS;
arg2.name = "Zoom";
break;
default:break;
}
}
@Override
public void setProperty(int arg0, Object arg1) {
switch(arg0)
{
case 0:
Bound = (String)arg1;
break;
case 1:
Zoom = (String)arg1;
break;
default:
break;
}
}
这是在本地构建服务器上的类（对象，即复杂类型）的匹配方式。 然后，您必须添加必要的属性，构建信封，添加映射和编组并发送请求。这些步骤都在我上面提到的链接中解释。
更新的 我将向您解释这些是什么：
<wsdl:message name="GetBoundDataSoapIn">
<wsdl:part name="parameters" element="tns:GetBoundData"/>
</wsdl:message>
什么时候是wsdl：消息，这意味着它是Web服务所需的功能。
它有 ，这意味着它需要一个GetBoundData类型的参数，它不是一个原始类型，实际上它是一个复杂的类型（对象）。
以下是步骤：
1-你必须写一个复杂类型GetBoundData（我已在上面写过）的本地表示，即类
2-在你的应用程序中，你必须创建一个函数来调用与＆＃34; GetBoundDataSoapIn＆＃34;相关的函数。在网络服务上。因此，创建一个名称相当的函数是一个很好的理想，例如：
public GetBoundData getBoundData()
{
try
{
SoapObject sobj = new SoapObject(YOUR_NAMESPACE,THE_METHOD_NAME);
//------------------------------------------------------------------------------
// GetBoundData :adding property
// <wsdl:message name="GetBoundDataSoapIn">
// <wsdl:part name="parameters" element="tns:GetBoundData"/>
// </wsdl:message>
// GetBoundData has two params:
// <s:element minOccurs="0" maxOccurs="1" name="Bound" type="s:string"/>
// <s:element minOccurs="0" maxOccurs="1" name="Zoom" type="s:string"/>
//
//--------------------------------------------------------------------------
//--------------
// GetBoundData
//--------------
PropertyInfo pi = new PropertyInfo();
pi.setName("GetBoundData");
pi.setValue(Whatever_value_your_supposed_to_put);// these values are "Bound" And "Zoom" , they're supposed to be gotten in your app somewhere
pi.setType(GetBoundData.class);
sobj.addProperty(pi);
//------------------------------
// START BUILDING SOAP ENVELOPE
//------------------------------
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
soapEnvelope.setOutputSoapObject(sobj);
//---------------------------------------------------------------------------------------
// MAPPINGS:
//---------------------------------------------------------------------------------------
soapEnvelope.addMapping(YOUR_NAMESPACE, GetBoundData.class.getSimpleName(), GetBoundData.class);
//---------------------------------------------------------------------------------------
// MARSHALLING:
//---------------------------------------------------------------------------------------
Marshal floatMarshal = new MarshalFloat();
floatMarshal.register(soapEnvelope);
AndroidHttpTransport aht = new AndroidHttpTransport(YOUR_URL);
aht.debug = true;
try
{
aht.call(YOUR_ACTION, soapEnvelope);
//Importat Outputs to check how the request/Response looks like.. Check Logcat to find these outputs
System.out.println("aht requestDump is :"+aht.requestDump);
System.out.println("aht responseDump is :"+aht.responseDump);
return soapEnvelope.getResponse();
}
catch (Exception e)
{
e.printStackTrace();
return "Exception: " + e.getMessage()+" message IS :" +e.getMessage()+" localizedmessage is :"+e.getLocalizedMessage();
}
}
catch(Exception ex)
{
ex.printStackTrace();
return "Exception: " + ex.getMessage();
}
}
}
因此请检查logCat以查看请求和响应的形状，并且您将看到是否必须获取响应并解析它以使用它，我不确定您的响应是什么，但在我的情况下它是一个多维数组，所以我不得不使用java功能解析它。
至于：
<wsdl:message name="GetBoundDataSoapOut">
<wsdl:part name="parameters" element="tns:GetBoundDataResponse"/>
</wsdl:message>
这只是告诉您Web服务发回响应。

检查NameSpace，方法名称。根据我的经验，当没有与webservice进行正确连接时，我们会收到此错误
