Question

我有一个连接到我们的.NET Web服务的应用程序，我发现我们正在为每个Web服务方法创建相同的方法，但唯一的区别是参数和Web服务方法。我正在寻找一种方法让下面的方法接受参数，然后管理1对几个更有用。

当前方法 * NameSpace，URL，argName，argValue都在类的顶部定义。

public static Document GetTickets() {
    try { 
        SoapObject request = new SoapObject(NameSpace, "GetTickets");         
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        request.addProperty(argName, argValue);

        request.addProperty("Customer", "ABC");
        request.addProperty("Local", "USA");

        envelope.setOutputSoapObject(request);
        androidHttpTransport.call("RemoteWebService/GetTickets", envelope); 

        SoapPrimitive responseData = (SoapPrimitive) envelope.getResponse();
        if (responseData != null)
        {
            //get the factory
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            //Using factory get an instance of document builder
            DocumentBuilder db = dbf.newDocumentBuilder();
            //parse using builder to get DOM representation of the XML file
            InputSource is = new InputSource(new StringReader(responseData.toString()));
            return db.parse(is);
        }
        else
            return null;
    }
    catch (Exception e)
    {
        Errors.LogError(e);
        return null;
    }
}

我希望它能成为这样的东西：

public static Document GetTickets(String WebServiceMethod, ArrayList Params) {
    try { 
        SoapObject request = new SoapObject(NameSpace, WebServiceMethod);         
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;

        //Syntax is wrong, I know, but just want to show what I'm looking to do:
        foreach(Parameter p in Params)
            request.addProperty(p[0].value, p[1].value);

        envelope.setOutputSoapObject(request);
        androidHttpTransport.call("RemoteWebService/" + WebServiceMethod, envelope); 

        SoapPrimitive responseData = (SoapPrimitive) envelope.getResponse();
        if (responseData != null)
        {
            //get the factory
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            //Using factory get an instance of document builder
            DocumentBuilder db = dbf.newDocumentBuilder();
            //parse using builder to get DOM representation of the XML file
            InputSource is = new InputSource(new StringReader(responseData.toString()));
            return db.parse(is);
        }
        else
            return null;
    }
    catch (Exception e)
    {
        Errors.LogError(e);
        return null;
    }
}

我尝试了几次不同的尝试，但却遇到了很多错误。我知道这很简单，但似乎无法解决这个问题。

我似乎已经找到了一个很好的方法，但欢迎任何反馈，如果这是好的：

创建了一个名为Parameter：

的类

public class Parameter {

    private String mParameterName;
    private String mParameterValue;

    // [[ ParameterName

    public void setParameterName(String ParameterName){
        mParameterName = ParameterName;
    }

    public String getParameterName(){
        return mParameterName;
    }

    // ]]

    // [[ ParameterValue

    public void setParameterValue(String ParameterValue){
        mParameterValue = ParameterValue;
    }

    public String getParameterValue(){
        return mParameterValue;
    }

    // ]]
}

然后修改我的方法以接受此类型的列表：

public static Document GetWebServiceData(String WebServiceMethod, List<Parameter> Params) {
    try { 
        SoapObject request = new SoapObject(NameSpace, WebServiceMethod);         
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;

        for(Parameter param : Params)
            request.addProperty(param.getParameterName(), param.getParameterValue());

        envelope.setOutputSoapObject(request);
        androidHttpTransport.call(NameSpace + "/" + WebServiceMethod, envelope); 

        SoapPrimitive responseData = (SoapPrimitive) envelope.getResponse();
        if (responseData != null)
        {
            //get the factory
            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

            //Using factory get an instance of document builder
            DocumentBuilder db = dbf.newDocumentBuilder();

            //parse using builder to get DOM representation of the XML file
            InputSource is = new InputSource(new StringReader(responseData.toString()));
            return db.parse(is);
        }
        else
            return null;
    }
    catch (Exception e)
    {
        Errors.LogError(e);
        return null;
    }
}

然后它就像这样被访问：

    List<Parameter> Params = new ArrayList<Parameter>();

    Parameter Param = new Parameter();
    Param.setParameterName("Customer");
    Param.setParameterValue("ABC");
    Params.add(Param);

    Param = new Parameter();
    Param.setParameterName("Local");
    Param.setParameterValue("USA");
    Params.add(Param);

    Document doc = GetWebServiceData("GetTickets", Params);

像魅力一样！希望这有助于其他人...

将参数传递给SOAP方法
