Java Webservice with Ksoap2 成功出现错误

Question

帮帮我，我在上面工作了大约 5 个小时，它不起作用。

不幸的是，一切都总是给出这样的回应：

output: anyType{RequestResult=anyType{Success=false; Message=Object reference not set to an instance of an object.; }; }

我的课程在这里：

public class WebServiceCallerImp implements  WebServiceCaller{
static final String NAMESPACE="http://tempuri.org/";
static final String SERVICE_URL="http://93.94.199.145/IPhoneIPad/Service.asmx";
static String METHOD="GetForexStocksandIndexesInfo";
static String SOAP_ACTION = "http://tempuri.org/GetForexStocksandIndexesInfo";
@Override
public String GetForex(GetForexInput input) {
SoapObject request = new SoapObject(NAMESPACE,METHOD);
request.addProperty("IsIPAD", "false");
request.addProperty("DeviceID", "test");
request.addProperty("DeviceType", "ipad");
request.addProperty("RequestKey", "UmVxdWVzdElzVmFsaWQxNjowNToyMDEyIDExOjU0%%");
request.addProperty("Period", "Month");

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

HttpTransportSE androidHttpTransport = new HttpTransportSE(SERVICE_URL);
androidHttpTransport.debug=true;
try {
    androidHttpTransport.call(SOAP_ACTION, envelope);
    SoapObject  response = (SoapObject) envelope.getResponse();
    System.out.println("output: "+response.toString());
    return response.toString();
}
    catch(Exception e){
        System.out.println("@@@@: "+ e.toString());
    }

return "null";
}}

我检查了 WSDL 的计量和参数：

 http: //93.94.199.145/IPhoneIPad/Service.asmx?WSDL

及其甲量：

http: //93.94.199.145/IPhoneIPad/Service.asmx?op=GetForexStocksandIndexesInfo

我的错误在哪里？

参数是结构请求{isipad， deviceid...} （参见 SoapUI 下）。所以参数是这样的，并将隐式类型设置为 true 以防止类型属性：

SoapObject request = new SoapObject(NAMESPACE,METHOD);
SoapObject req_params = new SoapObject(NAMESPACE, "request");
req_params.addProperty("IsIPAD", "false");
req_params.addProperty("DeviceID", "test");
req_params.addProperty("DeviceType", "ipad");
req_params.addProperty("RequestKey", "UmVxdWVzdElzVmFsaWQxNjowNToyMDEyIDExOjU0%%");
req_params.addProperty("Period", "Month");
request.addSoapObject(req_params);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.implicitTypes = true;
envelope.setOutputSoapObject(request);

不要问我为什么它返回"请求无效"。对于您提供的参数值，在 SoapUI 下也有相同的响应。我认为"DeviceId"参数无效，但真的不知道这个WS;)希望对您有所帮助马尔钦
