android调用webservice接口debug调试的时候报500错误

[justkankanxingbu]

SoapObject rpc = new SoapObject("http://tempuri.org/",
"QueryAllDrivingSchoolInfo");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);

rpc.addProperty("cityName", "常州");
rpc.addProperty("timeStamp", "1501461680");
rpc.addProperty("sign", "9AB17069FA0454412E8B7AC52C3C3D5C");

envelope.bodyOut = rpc;
envelope.dotNet = true;
envelope.setOutputSoapObject(rpc);
HttpTransportSE ht = null;
String result = "";
try {
ht = new HttpTransportSE("http://10.1.2.47:8000/CarNumWebService.asmx", 15000);

ht.debug = true;

ht.call(null, envelope);
result = (String) envelope.getResponse().toString();
} catch (Exception e) {
e.printStackTrace();
}



debug调试到获取异常的时候，报500错误，跪求什么原因。

http 500错误码对应的是内部服务器错误，我猜测可能有两个原因：1 参数有问题导致服务器内部异常报错；2 确认一下地址有没有问题
