当我尝试调用Web服务时出现KSoap错误消息

Question

我正在使用SOAP与写在.Net中的Webservice进行通信。源代码如下：

public class SlipperyAsSoap extends Activity { 

Button sendMsg; 
TextView resultText; 
EditText query; 

final String NAMESPACE = "http://tempuri.org/"; 
final String SOAP_ACTION = "http://tempuri.org/IIOService/SendMessage"; 
final String METHOD_NAME = "SupportedMessageTypes"; 
final String URL = "http://biovnap.no.netserver/Bio/IOService.svc?wsdl"; 

// private static String SOAP_ACTION1 = 
// "http://tempuri.org/FahrenheitToCelsius"; 
// private static String SOAP_ACTION2 = 
// "http://tempuri.org/CelsiusToFahrenheit"; 
// private static String NAMESPACE = "http://tempuri.org/"; 
// private static String METHOD_NAME1 = "FahrenheitToCelsius"; 
// private static String METHOD_NAME2 = "CelsiusToFahrenheit"; 
// private static String URL = 
// "http://www.w3schools.com/webservices/tempconvert.asmx?WSDL"; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    sendMsg = (Button) findViewById(R.id.button1); 
    resultText = (TextView) findViewById(R.id.textView1); 
    query = (EditText) findViewById(R.id.editText1); 
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
      .permitAll().build(); 
    StrictMode.setThreadPolicy(policy); 

    sendMsg.setOnClickListener(new OnClickListener() { 

     public void onClick(View arg0) { 

      // Initialize soap request + add parameters 
      SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

      // Use this to add parameters 
      // request.addProperty("Fahrenheit", 
      // query.getText().toString()); 

      // Declare the version of the SOAP request 
      SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11); 

      envelope.setOutputSoapObject(request); 
      envelope.dotNet = true; 

      try { 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(
         URL); 
       androidHttpTransport.debug = true; 
       // this is the actual part that will call the webservice 

       androidHttpTransport.call(SOAP_ACTION, envelope); 

       // Get the SoapResult from the envelope body. 
       SoapObject result = (SoapObject) envelope.bodyIn; 

       if (result != null) { 
        // Get the first property and change the label text 
        resultText.setText(result.getProperty(0).toString()); 
       } else { 
        Toast.makeText(getApplicationContext(), "No Response", 
          Toast.LENGTH_LONG).show(); 
       } 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } catch (XmlPullParserException e) { 
       Log.e("XMLPullParser: ", e.getMessage()); 
      } 
     } 

    }); 
} 
} 

正如您所看到的，我尝试联系W3Schools的Web服务，仅用于测试目的。而这个完美的作品，但是当我尝试联系我的web服务，这是在同一个网络我的手机在到达，我只得到了logcat的这个错误：

10-11 10:11:21.435: E/XMLPullParser:(1043): unexpected type (position:END_DOCUMENT null@1:1 in java.io.InputStreamReader@41a790d8) 

我试图达到的方法是这样的一种：

wsdl:operation name="SupportedMessageTypes"> 
<wsdl:input wsaw:Action="http://tempuri.org/IIOService/SupportedMessageTypes" message="tns:IIOService_SupportedMessageTypes_InputMessage"/> 
<wsdl:output wsaw:Action="http://tempuri.org/IIOService/SupportedMessageTypesResponse" message="tns:IIOService_SupportedMessageTypes_OutputMessage"/> 
</wsdl:operation> 

这个错误，当我尝试做一个androidHttpTransport.call(SOAP_ACTION, envelope);我知道，这应该被放在一个的AsyncTask，每个网络运营应当建立这样一来，所以请不要抱怨发生。

这里是WCF测试客户端

<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope"> 
    <s:Header> 
    <a:Action s:mustUnderstand="1">http://tempuri.org/IIOService/SupportedMessageTypes</a:Action> 
    <a:MessageID>urn:uuid:5c3f721a-f0d6-4be9-9699-10b48a2ee146</a:MessageID> 
    <a:ReplyTo> 
     <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address> 
    </a:ReplyTo> 
    </s:Header> 
    <s:Body> 
    <SupportedMessageTypes xmlns="http://tempuri.org/" /> 
    </s:Body> 
</s:Envelope> 

请求XML和响应XML

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing"> 
    <s:Header> 
    <a:Action s:mustUnderstand="1">http://tempuri.org/IIOService/SupportedMessageTypesResponse</a:Action> 
    <a:RelatesTo>urn:uuid:85436e79-86bb-4370-843c-b1047975b864</a:RelatesTo> 
    </s:Header> 
    <s:Body> 
    <SupportedMessageTypesResponse xmlns="http://tempuri.org/"> 
     <SupportedMessageTypesResult xmlns:b="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
     <b:string>EurodacTestReplyGenerator</b:string> 
     <b:string>EurodacBlock</b:string> 
     </SupportedMessageTypesResult> 
    </SupportedMessageTypesResponse> 
    </s:Body> 
</s:Envelope> 

任何人都可以给我这个错误消息的提示？

在此先感谢！

Answer 1

SOAP_ACTION是NAMESPACE + METHOD

所以，这就是我想你在呼唤自己的服务会是错误的。

假设您已更正分配方法和命名空间，下面应该工作。

final String NAMESPACE = "http://tempuri.org/"; 
final String SOAP_ACTION = "http://tempuri.org/IIOService/SupportedMessageTypes"; 
final String METHOD_NAME = "SupportedMessageTypes";
