Question

我是Twitters API和Twitter的twitter4j库的新手。我最近注册了一个应用程序，可以使用Twitter的API。 Twitter已授予我消费者API密钥（API密钥和API秘密密钥）以及访问令牌和访问令牌秘密。

问题是，我一直在尝试使用twitter4j（使用上述密钥）对Twitter进行身份验证，但是当尝试访问任何API资源时，我收到一条错误消息，原因是由于速率限制。但是，当我无法查询api时，如何达到速率限制？：，（

这是我正在尝试的操作（用敏感值替换敏感位）：

@SpringBootApplication
public class App 
{

    private static final String CONSUMER_KEY = "FakeConsumerKey";
    private static final String CONSUMER_SECRET = "FakeConsumerSecret";

    public static void main( String[] args )
    {
        SpringApplication.run(App.class, args);
        System.out.println("Making an authentication request to"
                + " retrieve the bearer token...");



        OAuth2Token token;
        token = getOAuth2Token();

        ConfigurationBuilder cb = new ConfigurationBuilder();

        cb.setApplicationOnlyAuthEnabled(true);
        cb.setOAuthConsumerKey(CONSUMER_KEY);
        cb.setOAuthConsumerSecret(CONSUMER_SECRET);
        cb.setOAuth2TokenType(token.getTokenType());
        cb.setOAuth2AccessToken(token.getAccessToken());

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

        try {
            System.out.println("My screen name: " + twitter.getScreenName());
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   

   }


    public static OAuth2Token getOAuth2Token()
    {
        OAuth2Token token = null;
        ConfigurationBuilder cb;

        cb = new ConfigurationBuilder();
        cb.setApplicationOnlyAuthEnabled(true);
        cb.setOAuthConsumerKey(CONSUMER_KEY);
        cb.setOAuthConsumerSecret(CONSUMER_SECRET);

        try
        {
            token = new TwitterFactory(cb.build())
                .getInstance().getOAuth2Token();

            System.out.println("token: " + token.getAccessToken());
        }
        catch (Exception e)
        {
            System.out.println("Can't get OAuth2 token");
            e.printStackTrace();
            System.exit(0);
        }

        return token;
    }

}

这是返回的错误：

403:The request is understood, but it has been refused. An accompanying error message will explain why. This code is used when requests are being denied due to update limits (https://support.twitter.com/articles/15364-about-twitter-limits-update-api-dm-and-following).

我哪里出错了？

getScreenName的定义

“返回验证用户的屏幕名称。如果以下情况，此方法可以在第一次调用时在内部调用verifyCredentials（） -此实例通过Basic进行身份验证，并提供电子邮件地址而非屏幕名称，或者-此实例通过 OAuth 进行身份验证。”

基于用户的身份验证必须使用OAuth 1.0a而不是OAuth2。您需要获取访问令牌，请按照以下步骤操作：
https://developer.twitter.com/en/docs/basics/authentication/overview/using-oauth

获取访问令牌后，只需像这样更新ConfigurationBuilder：

    ConfigurationBuilder cb = new ConfigurationBuilder();

    cb.setApplicationOnlyAuthEnabled(false);
    cb.setOAuthConsumerKey(CONSUMER_KEY)
    .setOAuthConsumerSecret(CONSUMER_SECRET)
    .setOAuthAccessToken(ACCESS_TOKEN)
    .setOAuthAccessTokenSecret(ACCESS_TOKEN_SECRET);
