Java android multipart / form-data

Question

这是我对soapUI的请求，我想用andorid发送它。

POST http://10.8.0.16:8080/SC_TerminalAssist/proxy/photos/note HTTP/1.1
Accept-Encoding: gzip,deflate

}

我这样做了：

   JSONObject jsonObject = new JSONObject();
    SharedPreferences sp ;
    sp = getSharedPreferences("pfref", Activity.MODE_PRIVATE);
    String pass = sp.getString("pass", "");
    String firm = sp.getString("firm", "");
    String login = sp.getString("login", "");
    String boundary;
    boundary = "===" + System.currentTimeMillis() + "===";

    try {
        jsonObject.put("company", firm);
        jsonObject.put("user", login);
        jsonObject.put("secure_password", HashUtil.md5(pass));
        jsonObject.put("secure_device_id", HashUtil.md5(DeviceUtil.getDeviceId(PhotoActivity.this)));
    } catch (JSONException e) {
        e.printStackTrace();
    }

    ImageLoader imageLoader = ImageLoader.getInstance();

    FileEntity fileEntity = null;
    try {
        fileEntity = new FileEntity(file, "image/jpeg");
    } catch (Exception e) {
        e.printStackTrace();
    }

    RequestParams params = new RequestParams();
    BasicHeader[] headers = new BasicHeader[]{new BasicHeader("Authorization", "SCToken " + token)};
    // params.put("photos", fileEntity);
    params.put("metadata",jsonObject);

    client.post(PhotoActivity.this, RestClient.getAbsoluteUrl("photos/note"), headers, params, "multipart/form-data", new AsyncHttpResponseHandler() {

        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            Log.d("sokces", "uploadFile response: " + statusCode);
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            Log.d("sokces nie", "uploadFile ERROR! " + statusCode);
            Log.d("fail " , new String(responseBody));
        }
    });

但它没有用，我做错了但我不知道自己做错了什么。我把我在android中做的和我放入soapUI的样本请求。
