我正在运行一个代码，让我的Webapp代表用户发布状态更新。代码在本地工作得很好，但当我把它放在Windows Server 2012 R2上时，我得到一个ConnectionException。
15-Sep-2015 18:40:59.128 SEVERE [http-apr-8080-exec-12] socialmedia.TwitterService.updateTwitterStatus null

属性配置如下
debug=true
oauth.consumerKey=CONSUMER_KEY
oauth.consumerSecret=CONSUMER_SECRET
oauth.accessToken=ACCESS_TOKEN
oauth.accessTokenSecret=ACCESS_TOKEN_SECRET
http.proxyHost=proxy
http.proxyPort=8080
代码:
@ApplicationScoped
public class TwitterService {
private Twitter twitter;
@Inject
private CmoTask task;
@PostConstruct
public void init() {
twitter = TwitterFactory.getSingleton();
}
public void updateTwitterStatus(String status) {
try {
twitter.updateStatus(status);
} catch (TwitterException ex) {
Logger.getLogger(TwitterService.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
奇怪的是我让它运行了几个小时。我想这可能与我后来在本地更改配置有关，而twitter不允许你在不同的位置使用相同的配置。现在我做了一个更新，它又不起作用了。我试着注册一个不同的web应用程序，并在.properties文件中使用这些键。不工作。
- 代理设置正确
- 服务器上的防火墙已关闭
我错过了什么?
提前感谢!
连接错误实际上取决于对服务器的访问。请检查您是否能够从chrome或任何其他web浏览器访问https://api.twitter.com。
