Question

我正在尝试形成对Twitter REST API的查询。有没有办法将gps坐标传递给查询并返回位于该位置特定半径内的推文。

Answer 1

使用GET search/tweets端点，您可以指定地理编码和半径，以从该区域内获取一组推文。参数值如下：纬度，经度，半径。

Ex：37.781157，-122.398720,1mi

Answer 2

请尝试以下代码。在尝试之前，您必须将一些值放入keyword，latitude，longitude和radius。 keyword是您搜索的内容，我认为您可以理解其他值的含义。

try {
        Query query = new Query(keyword); //

        GeoLocation location = new GeoLocation(latitude, longitude);
        String unit = Query.KILOMETERS; // or Query.MILES;
        query.setGeoCode(location, radius, unit);

        QueryResult result; 

        do {
            result = twitter.search(query);
            List<Status> tweets = result.getTweets();

            for (Status tweet : tweets) {
                System.out.println("@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
            }

        } while ((query = result.nextQuery()) != null);

    } catch (TwitterException te) {
        System.out.println("Failed to search tweets: " + te.getMessage());
        System.exit(-1);
    }

基于@Seohyun Choi回答，这是完整的java代码，带有身份验证。在编译此代码之前，请在路径中添加 twitter4j-core-3.0.5.jar 。

import java.util.List;
import twitter4j.GeoLocation;
import twitter4j.Query;
import twitter4j.QueryResult;
import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.conf.ConfigurationBuilder;

public class TweetsInParticularLocation {
    private static final String TWITTER_CONSUMER_KEY = "****";
    private static final String TWITTER_SECRET_KEY = "*****";
    private static final String TWITTER_ACCESS_TOKEN = "****";
    private static final String TWITTER_ACCESS_TOKEN_SECRET = "***";
public static void main(String arg[])
{
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey(TWITTER_CONSUMER_KEY)
        .setOAuthConsumerSecret(TWITTER_SECRET_KEY)
        .setOAuthAccessToken(TWITTER_ACCESS_TOKEN)
        .setOAuthAccessTokenSecret(TWITTER_ACCESS_TOKEN_SECRET);
    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();

    try {
        Query query = new Query("India"); //

        GeoLocation location = new GeoLocation(20.593684, 78.962880); //latitude, longitude
        String unit = Query.KILOMETERS; // or Query.MILES;
        query.setGeoCode(location, 1, unit); //location, radius, unit

        QueryResult result; 

        do {
            result = twitter.search(query);
            List<Status> tweets = result.getTweets();

            for (Status tweet : tweets) {
                System.out.println("@" + tweet.getUser().getScreenName() + " - " + tweet.getText());
            }

        } while ((query = result.nextQuery()) != null);

    } catch (TwitterException te) {
        System.out.println("Failed to search tweets: " + te.getMessage());
        System.exit(-1);
    }

}}
