在我的项目中，我正在尝试使用twitter4j集成 twitter 。我尝试使用示例代码登录办公室，我可以使用它成功发布推文，但是回到家我在 JCE.Jar 中遇到了奇怪的问题，上面写着

登录 twitter 的代码有点像这样。
public static void main(String args[]) thrwos Exception{
// The factory instance is re-useable and thread safe.
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer("[consumer key]", "[consumer secret]");
RequestToken requestToken = twitter.getOAuthRequestToken();
AccessToken accessToken = null;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
while (null == accessToken) {
System.out.println("Open the following URL and grant access to your account:");
System.out.println(requestToken.getAuthorizationURL());
System.out.print("Enter the PIN(if aviailable) or just hit enter.[PIN]:");
String pin = br.readLine();
try{
if(pin.length() > 0){
accessToken = twitter.getOAuthAccessToken(requestToken, pin);
}else{
accessToken = twitter.getOAuthAccessToken();
}
} catch (TwitterException te) {
if(401 == te.getStatusCode()){
System.out.println("Unable to get the access token.");
}else{
te.printStackTrace();
}
}
}
//persist to the accessToken for future reference.
storeAccessToken(twitter.verifyCredentials().getId() , accessToken);
Status status = twitter.updateStatus(args[0]);
System.out.println("Successfully updated the status to [" + status.getText() + "].");
System.exit(0);
}
private static void storeAccessToken(int useId, AccessToken accessToken){
//store accessToken.getToken()
//store accessToken.getTokenSecret()
}
