如何通過ksoap2創建SOAP請求

Question

<?xml version="1.0" encoding="UTF-8"?>

我在一個Android項目中工作，我想要使用一些JAX-WS。該服務是由別人做，所以我不能改變他們。我的東西要與這個編寫的代碼，但我收到的時候打電話給他們的唯一的事情來發送上述SOAP消息是顯示java.lang.NullPointerException

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(); 
} 

我認爲它甚至不會創建xml文檔，但我不知道如何檢查它。我試圖創建一個XmlSerializer來創建XML的數據，但我也收到一個NullPointerException。 那麼任何人都可以幫助我瞭解如何編碼上述請求？ 這裏的WSDL文件的某些部分

XSD文件的

<xs:schema xmlns:tns="http://poweb13/" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="1.0" targetNamespace="http://poweb13/"> 
<xs:element name="FReadStatus" type="tns:FReadStatus"/> 
<xs:complexType name="FReadStatus"> 
<xs:sequence> 
<xs:element name="arg0" type="xs:string" minOccurs="0"/> 
</xs:sequence> 
</xs:complexType> 

我應該有一個這樣的SOAP響應某些部分：

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> 

Answer 1

好了，所以你有一個函數FReadStatus：

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

它有一個元素FReadStatus複雜類型（即對象，它是在服務器上找到的類）。
此複雜類型具有String類型的屬性arg0。它的定義是：

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

所以，你需要創建一個實現kvmSerializable這種複雜類型映射到服務器上的相應類別的本地類，所以你會做什麼：

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; 
} 
} 

現在，你有這個類，你會做你有以下代碼：

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){} 

讓我知道發生了重量。您必須使用Logcat檢查requestDump和responseDump

UPDATE：回答你的問題有關UnknowHostException
可能的原因和解決方法

• 檢查在AndroidManifest.xml中你有：

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

• 如果您正在使用仿真器，請按照link

• 如果你使用了代理做：

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

• 您可能需要預熱的DNS使用，請在此link
