android - Soap Throws java.io.IOException:HTTP请求失败，HTTP状态:500

实际上，我用这段代码访问这个web服务FahrenheitToCelsius方法，得到了正确的响应，但是当我试图访问我的web服务时
java.io.ioexception:http请求失败，http状态：500
错误并指向transport.call(SOAP_ACTION, envelope);

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Use this to add parameters
request.addProperty("username",usr);
request.addProperty("password",pass);
request.addProperty("backOfficePartnerId",id);

//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);

envelope.setOutputSoapObject(request);

envelope.dotNet = true;

try {
    HttpTransportSE transport = new HttpTransportSE(URL);

    Log.i("bodyout", "" + envelope.bodyOut.toString());

    transport.call(SOAP_ACTION, envelope);

    // Get the SoapResult from the envelope body.
    SoapObject result = (SoapObject)envelope.bodyIn;
    System.out.println("result IN F TO C::"+result);
}catch(Exception e){
    e.printStackTrace();
}

我得到了正确的答复。我调试并检查了发送正确的body的值，作为响应，body in为空。

最佳答案

http status:500是一个内部服务器错误，它可能与您的.net服务器端编码有关。
