Question

在我的应用程序中，我调用wcf webservice方法通过base 64发送图像...在调用该方法后，我收到错误：

该方法写为：

public SoapPrimitive Base64ToImage(String base64String, String imgName) {
    SoapPrimitive result = null;

    try {
        SoapObject request = new SoapObject("http://tempuri.org/",
                "Base64ToImage");

        request.addProperty("base64String", base64String);
        request.addProperty("imgName", imgName);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);// soap envelop with version
        envelope.setOutputSoapObject(request); // set request object
        envelope.dotNet = true;

        HttpTransportSE androidHttpTransport = new HttpTransportSE(url1);// http
                                                                        // transport
                                                                        // call
        androidHttpTransport.call(
                "http://tempuri.org/IService/Base64ToImage", envelope);

        // response soap object

        result = (SoapPrimitive) envelope.getResponse();
        Log.e("Base64ToImage", result.toString());

    } catch (Exception e) {
        e.printStackTrace();
    }

    return result;

}

我无法弄清楚究竟是什么问题。

请帮忙！提前谢谢！
