Question

使用Kafka，我试图将数据从Twitter传输到Java，但是当我运行该程序时，出现此错误：

[hosebird-client-io-thread-0] WARN com.twitter.hbc.httpclient.ClientBase - Hosebird-Client-01 IOException caught when establishing connection to https://stream.twitter.com/1.1/statuses/filter.json?delimited=length&stall_warnings=true
[hosebird-client-io-thread-0] WARN com.twitter.hbc.httpclient.ClientBase - Hosebird-Client-01 failed to establish connection properly
[hosebird-client-io-thread-0] INFO com.twitter.hbc.httpclient.ClientBase - Hosebird-Client-01 Done processing, preparing to close connection

我正在尝试接收特定主题标签元素的流。我检查了pom.xml中的依赖项

<dependency>
  <groupId>com.twitter</groupId>
  <artifactId>hbc-core</artifactId> 
  <version>2.2.0</version>
</dependency>

运行curl命令，我收到以下消息：

$ curl -I https://stream.twitter.com

并尝试重新生成密钥和令牌。

这是代码段：

public void run(){

// Setting blocking queues
BlockingQueue<String> msgQueue = new LinkedBlockingQueue<String>(1000);

// create a twitter client
Client client = createTwitterClient(msgQueue);

// Establish a connection.
client.connect();

// looping thru code
// etc
}

public Client createTwitterClient(BlockingQueue<String> msgQueue){

// Declared the keys and tokens

// Host to connect to, the endpoint, and authentication (basic auth or oauth) */

Hosts hosebirdHosts = new HttpHosts(Constants.STREAM_HOST); <- this guy
StatusesFilterEndpoint hosebirdEndpoint = new StatusesFilterEndpoint();

// rest of the code for ClientBuilder and Client
}

其中Constants.STREAM_HOST为：

public static final String STREAM_HOST = "https://stream.twitter.com";

我希望建立连接并能够接收推文。 STREAM_HOST没有建立连接的原因是什么？

感谢那些阅读我的问题的人。

这似乎是由于我的笔记本电脑防火墙设置导致的。我在另一台安全性较低的笔记本电脑上尝试了完全相同的代码，它的工作原理就像一个魅力。将需要与管理员一起弄清楚。

如何修复Java中的卡夫卡错误“建立与https://stream.twitter.com的连接时捕获的IOException”？
