Android中的AsyncHttpClient框架下怎么post后台数据？

下面是后台拍的代码
public void baseInfo(Context context,RequestParams params, final HttpUtil.ReponseCallback callback){
HttpUtil.get(context,spellUrl(baseInfo_url), params, new TextHttpResponseHandler() {
@Override
public void onFailure(int i, Header[] headers, String s, Throwable throwable) {
callback.onFailure(s,throwable);
}
@Override
public void onSuccess(int i, Header[] headers, String s) {
EmpVo empVo = parseJsonToEmpVo(s);
callback.onSuccess(empVo);
}
});
}

    private String baseInfo_url="handler/EmpInfo.ashx";

    private EmpVo parseJsonToEmpVo(String result){
    EmpVo empVo=null;
    try {
        JSONObject obj=new JSONObject(result);
        int ret=obj.getInt("result");
        if(ret==0){
            //LogUtil.d(TAG,obj.getString("HREmployee").toString());
            empVo=gson.fromJson(obj.getString("HREmployee"),type_empVo);
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return empVo;
}

    RequestParams params=new RequestParams();
    params.put("sessionID", AppUtil.getUserVo().getSessionID());
    params.put("info", getResources().getString(R.string.hremployee));
    params.put(MyFilesActivity.EXTRA_XIASHUEMPID, xiaShuEmpId);
    myFilesAction.baseInfo(this, params, new HttpUtil.ReponseCallback<EmpVo>() {
        @Override
        public void onSuccess(EmpVo emp) {
            progressDialog.hideProgressDialog();
            if (emp != null) {
                empVo = emp;
                showInfo();
            } else {
                toast("暂无数据");
            }
        }

然后上面这几段是原来写好的能运行的获取后台json并解析成emp的代码

这个 当时学的时候 没太注意,就几句代码. 给我邮箱吧
