将日期传递给ASMX Web服务(Passing date to ASMX web service)

将日期传递给ASMX Web服务(Passing date to ASMX web service)

我使用asmx web服务在c＃over android设备上写。

我建立连接，当在一些web方法中我需要整数或字符串像输入参数，所有工作都很好，但问题是当web方法需要日期时，我尝试以多种格式发送日期但总是有问题得到答案。

我需要发送日期对象，还是喜欢字符串？ Web服务查看日期可能与其他内容类似吗？

这是与Web服务“通信”的方法：

public void connectSOAP() { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); String dateStr = "04/05/2010"; Date dateObj=null; SimpleDateFormat curFormater = new SimpleDateFormat("dd/mmm/yyyy"); try { dateObj = curFormater.parse(dateStr); } catch (java.text.ParseException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } request.addProperty("dtFrom",dateObj); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); envelope.dotNet = true; try { HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); if (envelope.getResponse() != null) { if (envelope.bodyIn instanceof SoapFault) { String str = ((SoapFault) envelope.bodyIn).faultstring; Log.i("", str); } else { SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; Log.d("WS", String.valueOf(resultsRequestSOAP)); } }; } catch (Exception e) { Log.d("WS","sss"); } }

当我改变web方法（其中有一些日期工作），我得到日志中的响应）但是当这种方式与日期我只是得到catch（“sss”）在日志中，我调试并发现它刹车：androidHttpTransport。 call（SOAP_ACTION，envelope）;

但我在日志中找不到任何关于它的东西，除了我设置的捕获...

I use asmx web service writes in c# over android device.

I make connection and when in some web method I need integer or string like input param,all work great, but problem is when web method need date, I try to send date in many format but always I have problem to get answer.

I need to send date object, or like string? It is possible that web service view date like something else?

This is method for "communication" with web service:

public void connectSOAP() { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); String dateStr = "04/05/2010"; Date dateObj=null; SimpleDateFormat curFormater = new SimpleDateFormat("dd/mmm/yyyy"); try { dateObj = curFormater.parse(dateStr); } catch (java.text.ParseException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } request.addProperty("dtFrom",dateObj); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); envelope.dotNet = true; try { HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); if (envelope.getResponse() != null) { if (envelope.bodyIn instanceof SoapFault) { String str = ((SoapFault) envelope.bodyIn).faultstring; Log.i("", str); } else { SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn; Log.d("WS", String.valueOf(resultsRequestSOAP)); } }; } catch (Exception e) { Log.d("WS","sss"); } }

When i change web method(something with out date it work),I get response in log) But when is this way with date i just get catch ("sss" ) in log,i debug and find that it brake on: androidHttpTransport.call(SOAP_ACTION, envelope);

But i not find anything about that in log except catch that i set...

最满意答案

对我来说，这看起来像你想要给web服务的dateObj无法解析，这就是为什么在这一行发生异常：

androidHttpTransport.call(SOAP_ACTION, envelope);

但是因为您的格式化程序具有以下格式：

SimpleDateFormat curFormater = new SimpleDateFormat("dd/mmm/yyyy");

也许（三！）“mmm”导致错误？ 我很确定这会产生像2月份的“2月”等等......（例如“2014年2月11日”）：

尝试以下方法：

SimpleDateFormat curFormater = new SimpleDateFormat("dd/mm/yyyy");

要么

SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yyyy");

顺便说一句，为了避免本地化和互操作性问题，我经常使用精确格式化为Strings的DateTime对象将这些对象提供给WebService。 因为很多时候我通过例如.asmx Webservice和J2EE Web服务之间的互操作性遇到了问题（例如，对于J2EE和.NET，DateTime的范围不同，如果它是null / nil值，你也会遇到麻烦）。

For me this looks like the dateObj which you want to give to the webservice can not be parsed, thats why the exception occurre at this line:

androidHttpTransport.call(SOAP_ACTION, envelope);

But as your formatter has this format:

SimpleDateFormat curFormater = new SimpleDateFormat("dd/mmm/yyyy");

Maybe the (three!)"mmm" are causing the error?? I am pretty sure this will produce something like e.g. "Feb" for February and so on.. (e.g. "11/Feb/2014"):

Try something like:

SimpleDateFormat curFormater = new SimpleDateFormat("dd/mm/yyyy");

or

SimpleDateFormat curFormater = new SimpleDateFormat("dd/MM/yyyy");

Btw, to avoid localisation and interoperability issues, i often use DateTime objects accurately formatted to Strings for giving that objects over to WebService. Because many times i had problems by interoperability between e.g. .asmx Webservice and J2EE web service (e.g. the range of DateTime is not the same for J2EE and .NET and if it's a null/nil value you also run in troubles).
