我一直试图阻止KSOAP2调用在通过Android从我的Axis2 Web服务请求数据时超时但是无法这样做。
Web服务的背景。
我的Web服务正在Apache Tomcat服务器上运行,用于返回工作站的实时信息。当我尝试浏览器时,它按预期工作,并且在网站上它也按预期工作。
问题
然而,当我尝试在我的Android应用程序中使用相同的方法时,有时我会得到以下堆栈跟踪错误。其他时候请求将成功。有时请求会立即超时,有时会在超时前等待一分钟。
设备
我已经通过三星Galaxy SII(平台2.3.3)和三星Galaxy SI(平台2.2.2)尝试使用WiFi并使用具有相同结果的3G。但是,通过仿真器(平台2.2)使用它时永远不会超时。
我的代码
String NAMESPACE = "http://service.domain.ie";
String URL = "http://www.myhost.com/axis2/services/RealTime?wsdl";
String METHOD_NAME = "getStationData";
String SOAP_ACTION = "RealTime";
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("stationType", getStationType());
request.addProperty("stationApiCode", getApiCode());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport;
SoapObject response = null;
try {
androidHttpTransport = new HttpTransportSE(URL,60000); // Tried Setting the Timeout to 1 Minute
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION,envelope);
response = (SoapObject)envelope.bodyIn;
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}

我已经将KSOAP2从2.4更新到2.5.7,并试图设置超时限制,但到目前为止我还没有成功。所以提出我的问题:
是否还有其他人遇到此问题,如果有,他们是如何解决的?
答案 0 :(得分:0)
超时启动时会抛出SocketTimeoutException。
你应该在try-catch中捕获它并按你喜欢的方式处理超时
