将简单字符串参数传递给 .net webservice 时出现问题
我有以下调用 .net Web 服务的代码。代码可以正常连接到服务,但参数(deviceid)似乎没有通过。该方法只是返回传递的 deviceid,该 ID 始终为 null。
这告诉我 deviceid 参数没有被传递。我想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 结合使用的吗?
活动代码
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();
}
web 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此问题。还有其他人有什么建议可以尝试吗?
从wire shark作为间谍发送的xml:

I have the following code which invokes a .net webservice. The code connects to the service fine, but the paramter(deviceid) does not appear to get passed. The method simply returns the passed deviceid which is always null.
This is telling me the deviceid parameter is not being passed. I thought I saw someone recommend a packet sniffer to view the outgoing xml, but can't seem to remember what it was. Can someone suggest one that i can use in conjunction with eclipse and windows.
activity code
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();
}
webservice code
<WebMethod()> _
Public Function CheckTrial(ByVal deviceid As String) As String
Return deviceid
End Function
I,ve tried everything and cannot figure out how to resolve this. Does anyone else have any suggestions to try?

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,而不是从您传递的信封中取出您的回复如果这不起作用:
您是否使用 ksoap2 for android(有 Java 版本和 Android 版本)?您的网络服务需要您登录吗?在尝试执行类似的任务时,我发现 ksoap 没有存储会话 cookie,特别是会话 id。我们必须
扩展
ServiceConnection 和 HttpTransportSE 将 cookie 保存为字符串,以便维护登录。就数据包嗅探器而言,请查看 钢丝鲨.
If I'm not mistaken,
ht.call(...)
returns a SoapSerializationEnvelope. I believe you need to pull your response out of that envelope and not out of the one you passed inIf that doesnt work:
Are you using ksoap2 for android (there is a Java version and an Android version)? does your webservice require you to log in? while trying to perform a similar task i found that ksoap was not storing session cookies, particularly the session id. we had to
extend
ServiceConnection and HttpTransportSE to save the cookie as a String in order to maintain a loginAs far as packet sniffers go, check out wire shark.
尝试设置
PropertyInfo
对象的命名空间。Try setting the namespace of the
PropertyInfo
object.尝试从 Web 服务中的命名空间中删除冒号 (:)...即只需将其设为
ikonicsoft.com
而不是http://ikonicsoft.com
- 并更新您的Soap 引用也调用以使用新的命名空间。这很疯狂,但这解决了我的问题(在黑莓上,但我认为同样的原则适用)。编辑 - 如果您尝试使用不属于您的 Web 服务,这并不理想,但它至少是使用您自己的 Web 服务的解决方案。我非常困惑为什么其中的冒号会把事情搞砸,但我注意到直接向 Web 服务器发送 HTML 帖子(通过远程登录到 Web 服务器上的端口 80),我得到了同样的错误。
Try removing the colon (:) from your namespace in the webservice... ie just make it
ikonicsoft.com
instead ofhttp://ikonicsoft.com
- and update your soap reference calls as well to use the new namespace. It's crazy, but this solved my problem (on Blackberry, but the same principles apply I think).Edit - this isn't ideal if you are trying to consume a webservice that you don't own, but it's at least a solution for consuming your own webservices. I am absolutely baffled as to why the colon in there is messing things up, but I noticed that doing an HTML post directly to the web server (by telnetting in to port 80 on the webserver), I get the same error.
