Ruby on Rails API与Android

Question

I am having trouble getting a 401 unauthorized response from the server,I am doing a "GET" call from a ruby on rails api the oauth token is in the header like this.

  urlConnection = (HttpURLConnection) url.openConnection();
            OAuth =   "bearer " + Base64.encodeToString(userpass.getBytes(), Base64.NO_WRAP);
            Log.e("auth", oAuth_token);
            urlConnection.setRequestMethod("GET");
            urlConnection.setRequestProperty("Authorization", OAuth);
            urlConnection.setRequestProperty("Content-Type", "application/json");
            urlConnection.setRequestProperty("Accept", "application/json");
            urlConnection.connect();

Userpass is the actual token.

This works in postman as well as on iOS but android is getting a 401

Answer 1

The Bearer Token Usage specification ( RFC 6750 ) is a bit confusing. You don't have to base64-encode the access token before use. To be concrete, your code should be simply like this:

OAuth = "Bearer " + userpass;

See this discussion where the questioner confessed he had had the same confusion as yours.
