Twitter4j身份验证凭据丢失

Question

我想在我的Android应用程序中使用Twitter4j发推文.这是我的代码:

 //TWITTER SHARE.
@Click (R.id. img_btn_twitter)
@Background
public void twitterPostWall(){

    try {


        //Twitter Conf.
        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true)
                .setOAuthConsumerKey(CONSUMER_KEY)
                .setOAuthConsumerSecret(CONSUMER_SECRET)
                .setOAuthAccessToken(ACCESS_KEY)
                .setOAuthAccessTokenSecret(ACCESS_SECRET);

        TwitterFactory tf = new TwitterFactory(cb.build());
        Twitter twitter = new TwitterFactory().getInstance();
        twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);

        try {
            RequestToken requestToken = twitter.getOAuthRequestToken();

            Log.e("Request token: ", "" + requestToken.getToken());
            Log.e("Request token secret: ", "" + requestToken.getTokenSecret());
            AccessToken accessToken = null;


        }

        catch (IllegalStateException ie) {

            if (!twitter.getAuthorization().isEnabled()) {
                Log.e("OAuth consumer key/secret is not set.", "");
            }
        }


        Status status = twitter.updateStatus(postLink);
        Log.e("Successfully updated the status to [", ""  + status.getText() + "].");

    }

    catch (TwitterException te) {
        Log.e("TWEET FAILED", "");

    }
}

我总是从Twitter4j收到此错误消息:java.lang.IllegalStateException:缺少身份验证凭据.有关详细信息,请参见http://twitter4j.org/en/configuration.html.但是你可以看到我正在使用构建器设置我的密钥.有人可以帮我解决一下吗？谢谢.

Answer 1

问题是以下几行.

TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = new TwitterFactory().getInstance();

您正在将配置传递给一个TwitterFactory实例,并使用另一个TwitterFactory实例来获取Twitter实例.

因此,你得到了 java.lang.IllegalStateException: Authentication credentials are missing

我建议你修改你的代码如下:

    //Twitter Conf.
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
            .setOAuthConsumerKey(CONSUMER_KEY)
            .setOAuthConsumerSecret(CONSUMER_SECRET)
            .setOAuthAccessToken(ACCESS_KEY)
            .setOAuthAccessTokenSecret(ACCESS_SECRET);

    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();

并使用此twitter实例.它会工作.
