我的android代码中有一个函数，该函数使用KSOAP将数据发送到Web服务。我能够将数据发送到服务，但有时会出现异常：“系统调用期间SSLException I / O错误，连接超时”。
经过几次测试后，我的观察结果是：
我对如何克服此例外一无所知。如果可以的话，建议/指导我如何克服此异常将是一个很大的帮助。
以下是用于将数据发送到Web服务的方法，该方法在ASYNC任务中被调用。
public String incidentDataToServer(JSONObject incidentJSON) {
// package the request
SoapObject Request = new SoapObject(INCIDENT_NAMESPACE,
INCIDENT_METHOD_NAME);
String incidentData = incidentJSON.toString();
PropertyInfo pi = new PropertyInfo();
pi.setName("IncidentJSonString");
pi.setValue(incidentData);
pi.setType(String.class);
Request.addProperty(pi);
// set the soap serialization envelope, set it to .net and package
// the entire request and pass to soap envelope.
SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
soapEnvelope.dotNet = true;
soapEnvelope.setOutputSoapObject(Request);
HttpTransportSE aht = new HttpTransportSE(URL);
try {
aht.call(INCIDENT_SOAP_ACTION, soapEnvelope);
SoapPrimitive resultString = (SoapPrimitive) soapEnvelope
.getResponse();
resIncident = resultString.toString();
} catch (Exception e) {
e.printStackTrace();
}
return resIncident;
}

谢谢。
这似乎类似于Android中的错误，该错误返回断开的连接：https://code.google.com/p/android/issues/detail?id=65463。
ksoap2-android库受到此影响，您的SOAP库也可能受到影响。引用问题：
[如果您将ksoap用于android：
ArrayList<HeaderProperty> headerPropertyArrayList = new ArrayList<HeaderProperty>();
headerPropertyArrayList.add(new HeaderProperty("Connection", "close"));
并使用.call(SOAP_ACTION, envelope, headerPropertyArrayList)更新您的通话。
我知道这个年龄较大，但只是增加了对话内容。
我经常在山上，当互联网中断或信号太弱时，收到此消息，正是在这一刻，我们向服务器发出了api的ssl握手信号。可以在该呼叫之前使用Internet，但是在途中，Internet会在确切的不方便时间点掉线
如果我绝对需要成功调用，我将采取缓解措施，那就是根据捕获的异常构建一个重试队列，并继续尝试该调用，直到调用成功或您得到某种确认为止。
出于这个原因，我也在探索将我的https网络调用转移到基于MQTT的协议上，以减少这些握手所需的开销。我们的应用程序在互联网不方便的地方（对于大多数人来说可能过分杀伤）是至关重要的。
