如何在安卓系统中调用ksoap web服务？

5

我有一个小困惑，在我们的移动应用程序中，类似下面这样从iOS调用ksoap web服务，且可以正确获取数据。在下面的web服务中，你可以看到从以下代码中需要传递一些参数到web服务中。

 -(void)callwebservice{
    NSString *soapMessage = [NSString stringWithFormat:
                             @"<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><Calculate xmlns=\"http://tempuri.org/\"><inputRate>%@</inputRate><rateFrequency xmlns:a=\"http://schemas.datacontract.org/2004/07/FusionPeople.MobileContractor.DomainModel\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><a:RateFrequencyId>0</a:RateFrequencyId><a:RateFrequencyName>%@</a:RateFrequencyName></rateFrequency><nonTaxableExpense>%@</nonTaxableExpense><expenseFrequency xmlns:a=\"http://schemas.datacontract.org/2004/07/FusionPeople.MobileContractor.DomainModel\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><a:RateFrequencyId>0</a:RateFrequencyId><a:RateFrequencyName>%@</a:RateFrequencyName></expenseFrequency></Calculate></s:Body></s:Envelope>\n",txtinputrate.text,lblrate.text,txtexpenses.text,lblexpense.text
                             ];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@MobileContractorCalculationService.svc",[MobileContractorAppDelegate getstrIpAddress] ]];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]];
    [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest addValue:@"http://tempuri.org/IMobileContractorCalculationService/Calculate" forHTTPHeaderField:@"SOAPAction"];
    [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
    if( theConnection ){
        webData = [NSMutableData data] ;
    }
}

在Android端，我尝试过很多种方法来调用这个Web服务并将数据传递给它。但是每次都会得到服务器端错误代码：415，请有人帮助我并告诉我如何将这种层级数据传递给此类型的KSOAP Web服务。

我尝试了以下代码：

try {

             SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

             request.addProperty("inputRate", 1000);

             SoapObject rate = new SoapObject(SOAP_ACTION, "rateFrequency");

             PropertyInfo info = new PropertyInfo();
             info.setName("RateFrequencyId");
             info.setValue(0);
             rate.addProperty(info);

             PropertyInfo info2 = new PropertyInfo();
             info2.setName("RateFrequencyName");
             info2.setValue("Hourly");
             rate.addProperty(info2);

             request.addProperty("rateFrequency", rate);

             request.addProperty("nonTaxableExpense", 500);

             SoapObject exp = new SoapObject(SOAP_ACTION, "expenseFrequency");

             PropertyInfo info3 = new PropertyInfo();
             info3.setName("RateFrequencyId");
             info3.setValue(0);
             exp.addProperty(info3);

             PropertyInfo info4 = new PropertyInfo();
             info4.setName("RateFrequencyName");
             info4.setValue("Hourly");
             exp.addProperty(info4);

             request.addProperty("expenseFrequency", exp);

             Log.v("", "=========== Request : " + request);

             SoapSerializationEnvelope envelope = new
             SoapSerializationEnvelope(
             SoapEnvelope.VER11);
             envelope.dotNet = true;
             envelope.setOutputSoapObject(request);
             HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

             try {
             androidHttpTransport.call(SOAP_ACTION, envelope);
             SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
             Log.v("myApp",
             "========================== Res" + response.toString());



             } catch (Exception e) {
             e.printStackTrace();
             }

但是它出现了以下错误：

请添加您的代码（Java代码，而不是iOS代码）和错误的堆栈跟踪，否则，请参考以下教程以了解如何使用ksoap2：http://mirnauman.wordpress.com/2012/10/18/android-calling-a-web-service-using-ksoap2-passing-values-to-a-web-service/ - Houcine

发布的代码看起来不像是Java代码，而更像与iOS相关的代码。 - Raghunandan

是的，@Raghunandan，实际上我已经发布了iOS代码，但我不确定如何在Android中使用它？ - mvts himm

我已经发布了我的Android代码，请刷新您的页面。 - mvts himm

@user2753221 请查看此链接：https://dev59.com/dnDYa4cB1Zd3GeqPBIN2。您的代码看起来没问题。 - Raghunandan

请尝试以下示例：

希望这能解决您的问题。

我使用以下方法调用ksoap web服务。

public String getServiceResponse(String nameSpace, String methodName,
        String soapAction, String Url, List<PropertyInfo> mPropertyInfo) {

    String mResponse = "";
    SoapObject request = new SoapObject(nameSpace, methodName);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    if (mPropertyInfo != null) {
        for (PropertyInfo propertyInfo : mPropertyInfo) {
            request.addProperty(propertyInfo);
        }
    }
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);

    HttpTransportSE ht = new HttpTransportSE(Url);
    ht.debug = true;
    try {
        ht.call(soapAction, envelope);
    } catch (IOException e) {
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
    try {
        mResponse = envelope.getResponse().toString();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return mResponse;
}
