在 RequestCenter 中，为什么明明方法是post，方法内部确是get, 逻辑不统一。为什么不统一为get方法呢，因为显然这里是获取数据。而在CommonOkHttpClient类中，post 和 get 方法定义内容是一样的。

//根据参数发送所有post请求
public static void postRequest(String url, RequestParams params, DisposeDataListener listener,
Class<?> clazz) {
CommonOkHttpClient.get(CommonRequest.
createGetRequest(url, params), new DisposeDataHandle(listener, clazz));
}

public static void requestRecommandData(DisposeDataListener listener) {
RequestCenter.postRequest(HttpConstants.HOME_RECOMMAND, null, listener,
BaseRecommandModel.class);
}

public static void requestRecommandMore(DisposeDataListener listener) {
RequestCenter.postRequest(HttpConstants.HOME_RECOMMAND_MORE, null, listener,
BaseRecommandMoreModel.class);
}

public static void requestFriendData(DisposeDataListener listener) {
RequestCenter.postRequest(HttpConstants.HOME_FRIEND, null, listener, BaseFriendModel.class);
}
