请教关于ksoap2接收byte[]的问题

[懒得抠虱子]

我在网上阅读了 郑昀 大哥关于ksoap2的文章（http://blog.csdn.net/zhengyun_ustc/archive/2007/01/17/1485436.aspx）后，编写了如下代码，想接收一个byte[]数据，但是程序运行时总提示ClassCastException，请问我应该怎样做才能正确的接收到这个byte[]数据呢？服务器是以二进制流的形式发送的。

    public byte[] downloadFile(String strUrl, String strFileID)
            throws IOException, XmlPullParserException {
        byte[] bResponse = null;
        HttpTransport ht = null;

        try {
            System.out.println("----------start---------");
            String serviceNamespace = strUrl;
            String methodName = "downloadFile";
            String serviceURL = strUrl;

            SoapObject request = new SoapObject(serviceNamespace, methodName);

            request.addProperty("FileID", strFileID);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

            envelope.bodyOut = request;
            (new MarshalBase64()).register(envelope);

            ht = new HttpTransport(serviceURL);

            ht.debug = true;
            ht.call(null, envelope);

            bResponse = (byte[])envelope.getResponse(); //这里总是报ClassCastException
        } finally {
            if (ht != null) {
                System.out.println("request dump>>" + ht.requestDump);
                System.out.println("response dump>>" + ht.responseDump);
            }
        }

        return bResponse;
    }

Object Response = envelope.getResult();
byte[] bResponse = org.kobjects.base64.Base64.decode(String.valueOf(Response));

这样也许可以。。我取byte[]的时候这样的。。顺利通过

[socool627]

贴一段我以前测试通过的代码。。。
//发送byte[],ws返回byte[]
SoapObject client = new SoapObject(serviceNamespace,methodName);
String data = new String(Hex.encode(dataPack));
client.addProperty("byte",new SoapPrimitive(SoapEnvelope.ENC, "base64",data));
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.bodyOut = client;
HttpTransport ht = new HttpTransport(serviceURL);
ht.call("", envelope);
Object ret = (Object)envelope.getResult();
String retString = String.valueOf(ret);
byte[] retByte[] = Base64.decode(retString);

刚有人告诉我Qk02BQAAAAAAADYEAAAoAAAAEAAAABAAAAABAAg...是base64编码过的，需要解码，就看到你的回复了。
非常感谢 socool627 问题解决了，呵呵，同样感谢楼上各位的帮忙，谢谢大家～呵呵

ClassCastException异常表示类型转换错误
envelope.getResponse();
这返回的是什么类型的，应该不是byte[]型的，仔细检查下

[懒得抠虱子]

请问j2me中应该怎么讲Object转为byte[]呢？j2me中没有ObjectInputStream

[yanhan0615]

查了一下api，返回一个object，那也不好判断了，lz吧envelope.getResponse()来system.out一下看看是什么东西在里面

[kf156]

按你给你地址，查看了下

//原文代码如下：
Object Response = envelope.getResult();
byte[] by = (byte[])Response;

//你的代码
bResponse = (byte[])envelope.getResponse(); 

是不是你调的方法错了...

我把envelope.getResponse().toString();打印出来是这样的东西：
Qk02BQAAAAAAADYEAAAoAAAAEAAAABAAAAABAAg....（后面还有很长csdn不让写太长...）


to: kf156 这两种写法都试过了，一样的错误
//原文代码如下：
Object Response = envelope.getResult();
byte[] by = (byte[])Response;

//你的代码
bResponse = (byte[])envelope.getResponse();

[yanhan0615]

晕倒了，lz啊，不是让你打他的toString（），你打一下envelope.getResponse().getClass()

[懒得抠虱子]

to: yanhan0615
打印出来是这个：
envelope.getResponse().getClass():class org.ksoap2.serialization.SoapPrimitive
