Question

我尝试使用Twitter hbc library根据位置获取推文。我已根据示例文件FilterStreamExample设置了我的代码。该示例有效，但是当我尝试向端点添加位置时，我得到致命错误代码：406。

以下是有效的代码：

StatusesFilterEndpoint endpoint = new StatusesFilterEndpoint();
endpoint.trackTerms(Lists.newArrayList("twitterapi", "#yolo"));

但是当我添加以下代码时，我收到错误：

Coordinate southwest = new Coordinate(-87.648926, 41.883109);
Coordinate northeast = new Coordinate(-87.606354, 41.828050);
Location chicago = new Location(southwest, northeast); 
endpoint.locations(Lists.newArrayList(chicago));

感谢您的帮助！

修改这是我的全部代码：

public class App {

  public static void oauth(String consumerKey, String consumerSecret, String token, String secret) throws InterruptedException {
    BlockingQueue<String> queue = new LinkedBlockingQueue<String>(100000);

    StatusesFilterEndpoint endpoint = new StatusesFilterEndpoint();
    Coordinate southwest = new Coordinate(-87.857666, 41.657347);
    Coordinate northeast = new Coordinate(-87.587128, 41.795712);
    Location chicago = new Location(southwest, northeast); 
    endpoint.locations(Lists.newArrayList(chicago));

    Authentication auth = new OAuth1(consumerKey, consumerSecret, token, secret);

    BasicClient client = new ClientBuilder()
      .name("exampleStream")
      .hosts(Constants.STREAM_HOST)
      .endpoint(endpoint)
      .authentication(auth)
      .processor(new StringDelimitedProcessor(queue))
      .build();

    // Establish a connection
    client.connect();
    PrintWriter writer;
    try {
      writer = new PrintWriter("twitterstream.txt", "UTF-8"); 
// Do whatever needs to be done with messages
      for (int msgRead = 0; msgRead < 1000; msgRead++) {
        if (client.isDone()) {
          System.out.println("Client connection closed unexpectedly: " + client.getExitEvent().getMessage());
          break;
      }
      String msg = queue.poll(5, TimeUnit.SECONDS);
      if (msg == null) {
        System.out.println("Did not receive a message in 5 seconds");
      } else {
        writer.println(msg);
      }
    }
     writer.close();
        } catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
      e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
      e.printStackTrace();
        }  

        client.stop();
}

  public static void main(String[] args) {
  try {
      App.oauth("LEDrJPDhn6C2trbde95WZg", "gEmlgewUodOoDjMNl2QbcqsbGvYDxNZWNRULchPE", "292576546-SWzEgMU7mC7Haat3lLEOQ0mXsZFwBf8F3ZKLBMVa", "ajPN2rGLx57yPoUjYe2qN4bE763orux4KwYeoCAvuLRPM");
  } catch (InterruptedException e) {
      System.out.println(e);
  }

}

Answer 1

问题可能是坐标。您应该在http://boundingbox.klokantech.com/上进行验证。选择选项＆＃34; csv＆＃34;之后划定这个地方。

Answer 2

您使用的是谷歌地图坐标吗？因为看起来你应该切换你的坐标点。

Coordinate southwest = new Coordinate(41.657347, -87.857666);
Coordinate northeast = new Coordinate(41.795712, -87.587128);

您也可以使用hbc快照版本https://github.com/twitter/hbc/issues/19 问候。

Answer 3

我已经检查了你的代码和我的Outh参数。有了我的工作，它与你的无关。这是问题

按位置过滤时使用hbc的致命错误代码406
