获得401请求与Android之内的指路牌访问令牌时

问题描述

下面是我的code，我不断收到一个例外授权失败（服务器回答一个401）。这可能是因为消费者关键是不正确或不签名不匹配。在这条线provider.retrieveAccessToken（消费者，验证）;。我有三重检查我的使用者密钥和机密，我的Twitter应用程序设置为浏览器，并尝试设置provider.setOAuth10a（真），我一直挣扎在这2天！我使用的路标1.2.1.1（核心及放大器; commonshttp4），如果有人可以帮助！请即时绝望

解决方案

刚刚发现了一个可能的解决方案：你需要设置一个回调网址上你的Twitter应用程序的帐户

Here is my code, i keep getting an exception "Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match." on this line 'provider.retrieveAccessToken(consumer, verifier);'. I have triple checked my consumer key and secret and my twitter application is set as a Browser and tried setting provider.setOAuth10a(true), i have been struggling on this for 2 days!! I am using signpost 1.2.1.1 (core & commonshttp4), If anyone can help! Please im desperate

            Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();

    @Override

            try {

                provider.setOAuth10a(true);
                provider.retrieveAccessToken(consumer, verifier);
                ACCESS_KEY = consumer.getToken();
                ACCESS_SECRET = consumer.getTokenSecret();

                AccessToken a = new AccessToken(ACCESS_KEY, ACCESS_SECRET);

                // initialize Twitter4J
                twitter = new Twitter();
                twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
                twitter.setOAuthAccessToken(a);
                String tweet = "#OAuth working via android app!";

                twitter.updateStatus(tweet);
                Toast.makeText(this, tweet, Toast.LENGTH_LONG).show();

            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
            }
        }

解决方案

Just found out a possible solution: You need to set a Callback URL on your twitter application account.
