java – 如何使用Twitter4J在推文中检索图像？

我想发出关键字或主题标签的查询,并从包含该关键字的所有推文中检索所有图像.我可以使用 Twitter4J与Java轻松发出查询并检索生成的推文.我知道http://t.co/xxxx链接我可以在浏览器中访问并查看相关图像.该图片位于https://pbs.twimg.com/xxxxx.所以我需要做的就是在我的代码中完成这个过程！

我可以很容易地解析每条推文中的http://t.co/xxxx链接.但是,当我从该链接检索所有html时,我没有看到任何https://pbs.twimg.com/xxxx图像:(.我认为正在发生的事情是Twitter正在通过JavaScript加载这些图像.

有什么方法可以轻松检索每条推文上的图像吗？

这是我到目前为止：

package com.company;

import twitter4j.*;
import twitter4j.conf.ConfigurationBuilder;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {

    public static void main(String[] args) throws Exception {
        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true)
                .setOAuthConsumerKey("xxxxxxxxxx")
                .setOAuthConsumerSecret("xxxxxxxxxxxx")
                .setOAuthAccessToken("xxxxxxxxx-xxx-xxxxxxxx")
                .setOAuthAccessTokenSecret("xxxxxxxxxxxxxxxxxxx");
        TwitterFactory tf = new TwitterFactory(cb.build());
        Twitter twitter = tf.getInstance();
        Query query = new Query("#hashtag");
        QueryResult result = twitter.search(query);
        Pattern pattern = Pattern.compile("http://t.co/w{10}");
        Pattern imagePattern = Pattern.compile("https://pbs.twimg.com/media/w+.(png | jpg | gif)(:large)?");
        for (Status status : result.getTweets()) {
            if (status.isRetweet())
                continue;
            System.out.println("@" + status.getUser().getScreenName() + ":" + status.getText());
            Matcher matcher = pattern.matcher(status.getText());

                if (matcher.find()) {
                    System.out.println("found a t.co url");
                    URL oracle = new URL(matcher.group());
                    BufferedReader in = new BufferedReader(
                            new InputStreamReader(oracle.openStream()));

                    String inputLine;
                    while ((inputLine = in.readLine()) != null) {
                        matcher = imagePattern.matcher(inputLine);

                        if (matcher.find())
                            System.out.println("YAYAAYAYAYYAYAYAYAYAYAYAYAYAAYAYYAYAAYYAYAYAYA: " + matcher.group());
                    }

                    in.close();

            }

        }
    }
}

MediaEntity[] media = status.getMediaEntities(); //get the media entities from the status
for(MediaEntity m : media){ //search trough your entities
    System.out.println(m.getMediaURL()); //get your url!
}
