使用Web服务和Ksoap2获取图像

当用户在智能手机的图库中选择一张照片时，我使用.net网络服务上传图片。

为了实现这一点，我使用了ksoap2。

在我的服务中，我发送一个字符串作为参数，我的代码如下：

File myFile = new File(imagepath);
Log.d(TAG, "myFile: " + myFile);
Request.addProperty("bytes", myFile);

SoapObject Request = new SoapObject(
        WSDL_TARGET_NAMESPACE, OPERATION_NAME);


SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
        SoapEnvelope.VER11);


envelope.dotNet = true;
envelope.setOutputSoapObject(Request);


HttpTransportSE androidHttpTransport = new HttpTransportSE(
        SOAP_ADDRESS);
androidHttpTransport.debug = true;

try {

    androidHttpTransport.call(SOAP_ACTION, envelope);

    SoapPrimitive resultString = (SoapPrimitive) envelope
            .getResponse();

    Log.d(TAG, "form webservice: "
            + resultString);

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

不幸的是，我的矢量显示为空，我在LogCat中得到解析错误：

我想知道是否有人可以帮我解决问题，你有什么建议？

提前致谢。

试试这个：

public void UploadImage(String image, String imageName) {

    String lStr = imagepath;

    File myFile = new File(imagepath);
    Log.d(TAG, "myFile: " + myFile);

    SoapObject Request = new SoapObject(WSDL_TARGET_NAMESPACE,
            OPERATION_NAME);

    byte[] bytearray = null;
    try {
        FileInputStream is = new FileInputStream(mFile);
        if (mFile != null)
            try {
                bytearray = streamToBytes(is);
            } finally {
                is.close();
            }
    } catch (Exception e) {
    }

    Request.addProperty("bytes", bytearray);

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);

    new MarshalBase64().register(envelope);
    envelope.dotNet = true;
    envelope.encodingStyle = "UTF-8";
    envelope.setOutputSoapObject(Request);

    HttpTransportSE androidHttpTransport = new HttpTransportSE(SOAP_ADDRESS);
    androidHttpTransport.debug = true;

    try {

        androidHttpTransport.call(SOAP_ACTION, envelope);

        SoapPrimitive resultString = (SoapPrimitive) envelope.getResponse();
        Log.d(TAG, "From webservice: " + resultString);

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


public static byte[] streamToBytes(InputStream is) {
    ByteArrayOutputStream os = new ByteArrayOutputStream(1024);
    byte[] buffer = new byte[1024];
    int len;
    try {
        while ((len = is.read(buffer)) >= 0) {
            os.write(buffer, 0, len);
        }
    } catch (java.io.IOException e) {
    }
    return os.toByteArray();
}


        new Thread(new Runnable() {
            public void run() {
                try {

                    String lStr = imagepath;
                    UploadImage(
                            imagepath,
                            lStr.substring(lStr.lastIndexOf("/")).replace(
                                    "/", ""));
                } catch (Exception e) {
                    e.printStackTrace();
                    Log.e(TAG, "Error..", e);
                }
            }
        }).start();
