Android:系统调用期间出现 SSLException I/O 错误，连接超时

Question

我的 android 代码中有一个函数，它使用 KSOAP 将数据发送到 Web 服务。我能够向服务发送数据，但有时会出现异常:“系统调用期间发生 SSLException I/O 错误，连接超时”。

在进行了几次测试后，我的观察结果是:

• 如果 wifi/移动数据已经打开并且我将数据发送到网络服务，我不会遇到异常。
• 只有当我打开 wifi/移动数据时，当我尝试发送数据时，我才会收到它。

我不知道如何克服这个异常。如果可以的话，请建议/指导我如何克服这个异常，这将是一个很大的帮助。

以下是用于将数据发送到在 ASYNC 任务中调用的 Web 服务的方法。

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;

    }

这似乎类似于 Android 中返回断开连接的错误:https://code.google.com/p/android/issues/detail?id=65463 .

ksoap2-android 库受此影响，您的 SOAP 库也可能受到影响。引用问题:

If you use ksoap for android:

ArrayList<HeaderProperty> headerPropertyArrayList = new ArrayList<HeaderProperty>();
headerPropertyArrayList.add(new HeaderProperty("Connection", "close"));

并使用 .call(SOAP_ACTION, envelope, headerPropertyArrayList) 更新您的调用。
