How to make OAuth2 Authorization Request via POST to Custom API using Scribe

Question

Hello fellow developers...

I am new to oauth2 and I found Scribe Java Library which suits my needs... but the problem is that I have my own oauth2 server which receives request via POST and user credentials are passed through PAYLOAD "application/x-www-form-urlencoded"

Here you can see sample request: SCREENSHOT

And when I try to implement my own ApiClass using documentation

https://github.com/fernandezpablo85/scribe-java/wiki/Custom-Apis

and I noticed that client credentials are attached to url

private static final String AUTHORIZE_URL = "http://jimbo.com/oauth/authorize?token=%s";

which means authorization requests are made via GET :(

How to configure ApiClass properly to make POST request?

Thanks in advance :)

UPD: for the OAuth2 Server Side I am using

github.com/Filsh/yii2-oauth2-server

Try using RestTemplate in android for making post, get or exchange type requests. — We are Borg, Sep 04 '15 at 07:42
If you want, I can always put some samples, but there are lots of samples already available on net. — We are Borg, Sep 04 '15 at 07:56
@WeareBorg Thank you for your answer:) I was thinking about implementing my own library for OAuth2... Any help appreciated ^_^ — JavaMachine, Sep 04 '15 at 12:54
@WeareBorg btw) It would be great, If you could provide some samples :) — JavaMachine, Sep 04 '15 at 13:20
Why dont you post the server side which is in POST, and the code you have until now for your client side... Edit your main post and paste it there. — We are Borg, Sep 04 '15 at 13:22
@WeareBorg for the server side I am using https://github.com/Filsh/yii2-oauth2-server :) and for client side I have done nothing))) just Empty project where I imported bunch of OAuth2 client libraries) and testing them) — JavaMachine, Sep 04 '15 at 13:33
I have made a sample method for you, here it is with some comments : http://pastebin.com/q2kgpcXx — We are Borg, Sep 04 '15 at 13:45

As the result I deleted Scribe from my project... and implemented own method for getting access token...

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://127.0.0.1/oauth2/token");
    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("grant_type", "password"));
        nameValuePairs.add(new BasicNameValuePair("username", username));
        nameValuePairs.add(new BasicNameValuePair("password", password));
        nameValuePairs.add(new BasicNameValuePair("client_id", clientID));
        nameValuePairs.add(new BasicNameValuePair("client_secret", clientSecret));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

        JSONObject json_auth = new JSONObject(EntityUtils.toString(response.getEntity()));
        String token = json_auth.getString("access_token");

    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }
