나는이 라이브러리에서 나를 훈련시키기 위해 twitter4j의 기본 기능을 작동 시키려고합니다. 내 첫 번째 테스트는 내 타임 라인을 검색하는 것입니다 사이트 twitter4j에 대한 첫 번째 튜토리얼 중 하나입니다.Twitter4j, 알 수없는 호스트 예외
여기 내 타임 라인을 검색하려면 코드는 다음과 같습니다
String accessToken = "***";
String accessSecret = "***";
String consumerKey = "***";
String consumerSecret = "***";
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(consumerKey)
.setOAuthConsumerSecret(consumerSecret)
.setOAuthAccessToken(accessToken)
.setOAuthAccessTokenSecret(accessSecret);
TwitterFactory tf = new TwitterFactory(cb.build());
Twitter twitter = tf.getInstance();
List<Status> statuses = twitter.getHomeTimeline();
System.out.println("Showing home timeline.");
for (Status status : statuses) {
System.out.println(status.getUser().getName() + ":" +
status.getText());
}
그러나이 간단한 코드
, 나는 다음과 같은 오류가 있습니다Exception in thread "main" api.twitter.com
