.net - 将简单字符串参数传递给 .net webservice 时出现问题

Question

我有以下调用 .net 网络服务的代码。代码可以很好地连接到服务，但参数(deviceid)似乎没有通过。该方法仅返回传递的 deviceid，它始终为 null。

这告诉我没有传递 deviceid 参数。我以为我看到有人推荐一个数据包嗅探器来查看传出的 xml，但似乎不记得它是什么。有人可以推荐一个我可以与 eclipse 和 windows 结合使用的工具吗？

Activity 代码

    String deviceid = tManager.getDeviceId();

    SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME);

    PropertyInfo pi = new PropertyInfo();

    pi.setName("deviceid");
    pi.type = PropertyInfo.STRING_CLASS;
    pi.setValue(deviceid.toString());
    request.addProperty(pi);

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

    HttpTransportSE ht = new HttpTransportSE(URL);


    try{
        ht.call(SOAP_ACTION, soapEnvelope);
        SoapPrimitive result = (SoapPrimitive ) soapEnvelope.getResponse(); 


        Toast.makeText(ctx, "result = " + result.toString(), Toast.LENGTH_SHORT).show();

    }catch(Exception e){
        e.printStackTrace();
        Toast.makeText(ctx, "error: " + e.getMessage(), Toast.LENGTH_SHORT).show();

    }

网络服务代码

        <WebMethod()> _
    Public Function CheckTrial(ByVal deviceid As String) As String

        Return deviceid
    End Function

我已经尝试了所有方法，但无法弄清楚如何解决这个问题。还有其他人有什么建议可以尝试吗？

从 wire shark 发送的 xml:

Answer 1

如果我没记错的话，ht.call(...) 返回一个 SoapSerializationEnvelope。我相信您需要从信封中取出您的回复，而不是从您递交的信封中取出

SoapSerializationEnvelope responseEnvelope = ht.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive result = (SoapPrimitive ) responseEnvelope.getResponse(); 

如果这不起作用:您是否在使用 ksoap2 for android(有 Java 版本和 Android 版本)？您的网络服务是否需要您登录？在尝试执行类似的任务时，我发现 ksoap 没有存储 session cookie，尤其是 session ID。我们必须扩展 ServiceConnection 和 HttpTransportSE 以将 cookie 保存为字符串以维护登录

就数据包嗅探器而言，查看 wire shark .
