Android Studio 中的 Last.FM API 404 错误

Question

我正在尝试通过 Android Studio 和 Loopj Android AsyncHttpClient 插件 (http://loopj.com/android-async-http/) 使用 last.fm API (http://www.last.fm/api/mobileauth)，但我不断收到 404 错误，但不明白为什么。代码如下。我究竟做错了什么？谢谢。

RequestParams params = new RequestParams();
params.put("username", "myusername");
params.put("password", "mypassword");
params.put("api_key", "myapikey");
params.put("api_sig", "myapisecret");

LastFMRestClient.post("http://ws.audioscrobbler.com/2.0/", params,
    new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            Log.e("MUSIC SERVICE", "Success");
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            String msg = "Object *" + statusCode + "*" + responseBody;
            Log.e("MUSIC SERVICE", "Failed: " + msg);
            // Outputs: Failed: Object *404*[B@17f1042c
        }

        public void onFinish() {
            Log.e("MUSIC SERVICE", "Finished");
        }
    }
);
