BufferedInputStream已关闭

Question

我正在开发一个android应用程序，其中包含一个在登录页面忘记密码的概念。我正在对此应用程序使用Soap Web服务。

这是我的代码：

public void fncCallForgotPasswordService() {
        String SOAP_ACTION = "http://example.org/ForgotPWD";
        String METHOD_NAME = "ForgotPWD";;
        String NAMESPACE = "http://example.org/";
        String URL = "https://in.xyz.com/abcd.example/MethodExample.asmx";

        try {
            SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
            Request.addProperty("UID", strUserID);
            Request.addProperty("CID", strCompID);

            SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            soapEnvelope.dotNet = true;
            soapEnvelope.setOutputSoapObject(Request);

            HttpTransportSE transport = new HttpTransportSE(URL);
            transport.call(SOAP_ACTION, soapEnvelope);
            resultString = (SoapObject) soapEnvelope.getResponse();
            resultString = (SoapObject) resultString.getProperty("Data");
            resultString = (SoapObject) resultString.getProperty("Row");
            strMessage = resultString.getPropertyAsString("Message");

            if (resultString != null) {
                Log.i("Message", strMessage);
            }

            Log.i("Result", "Result Celsius: " + resultString);
        } catch (Exception ex) {
            Log.e("Error", "Error: " + ex.getMessage());
        }
    }

web服务提供了新密码，但问题是我得到了一个异常，它说

org.xmlpull.v1.XmlPullParserException: Invalid stream or encoding: java.io.IOException: BufferedInputStream is closed (position:START_DOCUMENT null@1:1) caused by: java.io.IOException: BufferedInputStream is closed

首次调用web服务时，SoapObject 'resultString‘显示为null，并显示上述异常。但当我连续第二次或第三次尝试时，没有抛出异常。只有在第一次调用忘记密码web服务时，它才会抛出上述异常。

此外，无论是否有例外，我的手机上都会收到新密码。

但我关心的是为什么会发生这种异常。

请帮帮我！

提前谢谢。

尝试自定义超时值，而不是非标准超时值：

HttpTransportSE androidHttpTransport = new HttpTransportSE(this.url,this.connectionTimeout)
