java - twitter4j:获取用户的全名、简介、位置、URL(按用户名)

Question

如何通过知道 twitter4j 中的用户名来获取用户的全名、简介、位置和 url？

Twitter twitter = new TwitterFactory().getInstance();
User user = twitter.showUser(username); // this line
if (user.getStatus() != null) {
    System.out.println("@" + user.getScreenName() + " - " + user.getDescription());
} else {
    // protected account
    System.out.println("@" + user.getScreenName());
}

返回

java.lang.IllegalStateException: Authentication credentials are missing.

( token 等在开始时定义。推文当然也需要身份验证，可以很好地工作)

Answer 1

您忘记将身份验证传递给 TwitterFactory

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey("CONSUMER_KEY"); 
cb.setOAuthConsumerSecret("CONSUMER_SECRET"));
cb.setOAuthAccessToken("TOKEN");
cb.setOAuthAccessTokenSecret("TOKEN_SECRET");
Twitter twitter = new TwitterFactory(cb.build()).getInstance();
....
