Twitter OAuth parametro non valido oauth_verifier

Question

Io sono l'attuazione OAuth da Java con la sequenza folowing:

1) Invio https POST: //api.twitter.com/oauth/request_token (con callback) Twitter reponse contiene oauth_token, oauth_token_secret e oauth_callback_confirmed = true

2) Reindirizzamento a https:? //api.twitter.com/oauth/authenticate oauth_token = {oauth_token dalla risposta precedente da Twitter}

appare 3) Twitter form di login, clicco su il pulsante "login".

4) Twitter reindirizza a {} callback_url oauth_token = {questo token è uguale a gettone da OAuth risposta/request_token} & oauth_verifier = {} verificatore

5) https POST:? //api.twitter.com/oauth/access_token con l'intestazione Oauth include oauth_token, corpo del messaggio contiene oauth_verifier = {} verificatore ritornato

6) risposta Twitter = errore durante l'elaborazione della richiesta OAuth: parametro non valido oauth_verifier

Cosa c'è di sbagliato con oauth_verifier?

Compute firma del metodo:

private static String computeSignature(String baseString, String keyString) throws GeneralSecurityException, UnsupportedEncodingException { 
     SecretKey secretKey = null; 

     byte[] keyBytes = keyString.getBytes(); 
     secretKey = new SecretKeySpec(keyBytes, "HmacSHA1"); 

     Mac mac = Mac.getInstance("HmacSHA1"); 
     mac.init(secretKey); 

     byte[] text = baseString.getBytes(); 

     return new String(Base64.encodeBase64(mac.doFinal(text))).trim(); 
    }

Answer 1

Ho sperimentato la stessa identica situazione con il nostro codice di JavaScript. Dopo aver lottato un giorno, ho trovato una soluzione che risolve l'errore. Aggiungendo semplicemente un'intestazione "Content-Type" con valore di "application/x-www-form-urlencoded".

Il mio codice è stato utilizzato per funzionare correttamente, ma smette di funzionare negli ultimi due mesi. La mia ipotesi è che Twitter abbia recentemente modificato l'implementazione della gestione di OAuth che ci obbliga ad aggiungere il tipo di contenuto esplicitamente.
