我在JRE 1.6上使用Jersey 1.13编写了几个REST服务.一切都在本地运行正常,但在我部署到GAE后,我收到此错误:

我在将Android应用中的照片上传到GCS时遇到问题.我可以上传文本文件而不上传照片.我尝试了各种mime类型以及不同的Base64编码方法(decodeBase64,encodeBase64URLSafeString等...)

我觉得我真的很亲密.

这是我收到的错误消息:

com.google.appengine.repackaged.org.codehaus.jackson.JsonParseException:base64内容中的非法字符'_'(代码0x5f)[来源:N/A; line:-1,column:-1]

我看了编码的字符串,那里没有任何'_'.

Android代码:

Activity:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        switch (requestCode)
        {
            case 0:
            {

                try
                {



                        InputStream is = getContentResolver().openInputStream(data.getData());

                        tvMessage.setText("Done!");

                        byte[] b = getBytes(is);

                        gaeTask task = new gaeTask();

                        PhotoObject p = new PhotoObject();

                        p.encodeBytes(b);
                        p.setName("picturejpg.jpg");

                        task.execute(p);
                }
}
AsnycTask:
protected String doInBackground(PhotoObject... params)
        {
            String responseMessage = "";

            try
            {
                PhotoObjectEndpoint builder = new PhotoObjectEndpoint(AndroidHttp.newCompatibleTransport(), new JacksonFactory(), new HttpRequestInitializer()
                {

                    @Override
                    public void initialize(HttpRequest arg0) throws IOException
                    {
