缺少 Twitter4j 身份验证凭据 [英] Twitter4j authentication credentials are missing

问题描述

我想在我的 Android 应用程序中使用 Twitter4j 发一条推文.这是我的代码:

I would like to make a tweet with Twitter4j in my Android app. Here is my code:

 //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:身份验证凭据丢失.有关详细信息，请参阅 http://twitter4j.org/en/configuration.html.但是正如您所看到的，我正在使用构建器来设置我的密钥.有人可以帮我解决吗?谢谢.

I always get this error message from Twitter4j: java.lang.IllegalStateException: Authentication credentials are missing. See http://twitter4j.org/en/configuration.html for the detail. But as you can see I'm using builder to set my key. Can someone help me to fix it please? thanks.

推荐答案

问题在于以下几行.

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.

You are passing the configuration to one TwitterFactory instance and using another TwitterFactory instance to get the Twitter instance.

因此，你得到java.lang.IllegalStateException:缺少身份验证凭据

我建议你修改你的代码如下:

I suggest you to modify your code as follows:

    //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.它会起作用.

And use this twitter instance. It will work.
