【问题描述】：

我正在尝试使用 android-Ksoap2 库从 SOAP API 获得响应。但结果出乎我的意料。 API 工作正常。我使用带有 XML 的 POST 请求对 POSTMAN 进行了测试。

我使用 XML 文件发出的请求是..（名称空间被屏蔽）

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
    <Body>
        <GetRealTimeStopData xmlns="******">
            <stopId>1295</stopId>
            <forceRefresh>true</forceRefresh>
        </GetRealTimeStopData>
    </Body>
</Envelope>

我尝试将 SoapObject 解析为有人建议的 SoapPrimitive。但没有运气。

class SoapAsyncTask: AsyncTask<String, Void, String>() {

    var URL = "******" //masking
    var NAMESPACE = "******" // masking
    var METHOD_NAME = "GetRealTimeStopData"

    override fun doInBackground(vararg params: String): String {
        var result = ""
        val soapObject = SoapObject(NAMESPACE, METHOD_NAME)

        val propertyInfo = PropertyInfo()
        propertyInfo.type = Int::class.java
        propertyInfo.name = "stopId"
        propertyInfo.value = params[0]
        soapObject.addProperty(propertyInfo)

        val propertyInfo1 = PropertyInfo()
        propertyInfo1.type = Boolean::class.java
        propertyInfo1.name = "forceRefresh"
        propertyInfo1.value = true
        soapObject.addProperty(propertyInfo1)

        Log.wtf("** DEBUG ** number of property ", soapObject.propertyCount.toString())
        Log.wtf("** DEBUG ** stopId ", soapObject.getProperty(0).toString())
        Log.wtf("** DEBUG ** forceRefresh ", soapObject.getProperty(1).toString())

        val envelope = SoapSerializationEnvelope(SoapEnvelope.VER11)
        envelope.setOutputSoapObject(soapObject)
        envelope.dotNet = false

        val httpTransportSE = HttpTransportSE(URL)

        try {
            httpTransportSE.call(getSoapAction(METHOD_NAME), envelope)
            Log.wtf("** DEBUG ** envelope.response ", envelope.response.toString())
            var resultObject: SoapObject = envelope.response as SoapObject
            var soapPrimitiveObject: SoapPrimitive = resultObject as SoapPrimitive
            result = soapPrimitiveObject.toString()
        } catch (e: Exception) {
            e.printStackTrace()
        }

        return result

    }

    override fun onPostExecute(s: String) {
        Log.wtf("** DEBUG **", s)
    }

    private fun getSoapAction(method: String): String {
        return "\"" + NAMESPACE + method + "\""
    }

}

并且错误日志如下。

【解决方案1】：

我实际上解决了这个问题。为了将来参考，我正在写下我是如何解决的。

这是我的问题的一部分。

envelope.dotNet = true

完整方法。

fun getRealTimeStopData(stopId : String?, forceRefresh: String?) : MutableList<Bus> {

        var busList: MutableList<Bus> = mutableListOf()
        val METHOD_NAME = "GetRealTimeStopData"
        val SOAP_ACTION = Utils.SOAP_NAMESPACE + METHOD_NAME
        val soapObject = SoapObject(Utils.SOAP_NAMESPACE, METHOD_NAME)

        soapObject.addProperty("stopId", stopId)
        soapObject.addProperty("forceRefresh", forceRefresh)

        val envelope = SoapSerializationEnvelope(SoapEnvelope.VER11)
        envelope.setOutputSoapObject(soapObject)

        envelope.dotNet = true // This should be TRUE *important 

        val httpTransportSE = HttpTransportSE(Utils.SOAP_URL)

        try {
            httpTransportSE.call(SOAP_ACTION, envelope)
            val soapPrimitive: SoapObject = envelope.response as SoapObject

            // index 1 is Stopdata.
            var data: SoapObject = soapPrimitive.getProperty(1) as SoapObject
            // get to "Document Element"
            if(data.hasProperty("DocumentElement")){
                var documentElement: SoapObject = data.getProperty("DocumentElement") as SoapObject

                for(i in 1..documentElement.propertyCount) {
                    var obj = documentElement.getProperty(i-1) as SoapObject

                    var bus = Bus()
                    bus.MonitoredStopVisit_MonitoringRef = obj.getProperty("MonitoredStopVisit_MonitoringRef").toString()
                    bus.MonitoredVehicleJourney_LineRef = obj.getProperty("MonitoredVehicleJourney_LineRef").toString()
                    bus.MonitoredVehicleJourney_DirectionRef = obj.getProperty("MonitoredVehicleJourney_DirectionRef").toString()
                    bus.MonitoredVehicleJourney_PublishedLineName = obj.getProperty("MonitoredVehicleJourney_PublishedLineName").toString()
                    bus.MonitoredVehicleJourney_DestinationRef = obj.getProperty("MonitoredVehicleJourney_DirectionRef").toString()
                    bus.MonitoredVehicleJourney_DestinationName = obj.getProperty("MonitoredVehicleJourney_DestinationName").toString()
                    bus.MonitoredCall_ExpectedArrivalTime = obj.getProperty("MonitoredCall_ExpectedArrivalTime").toString()
                    bus.MonitoredCall_ExpectedDepartureTime = obj.getProperty("MonitoredCall_ExpectedDepartureTime").toString()

                    busList.add(bus)
                }
            } else {
                Log.v("**DEBUG**","busList size : " + busList.size.toString())
            }
        } catch (e: Exception) {
            e.printStackTrace()
        }

        return busList
    }

class Bus {
    lateinit var MonitoredStopVisit_MonitoringRef: String
    lateinit var MonitoredVehicleJourney_LineRef: String
