java - 在 Twitter4j 中检索 OEmbed 对象时出现问题

Question

我正在尝试从 Twitter4j 中的 Status 对象获取 OEmbed 对象，然后获取要传递到网页的 html。现在我只是将它放在一个主要方法中进行测试。

public static void main(String[] args) {
    ConfigurationBuilder cf = new ConfigurationBuilder();

    cf.setDebugEnabled(true)
        .setOAuthConsumerKey("")
        .setOAuthConsumerSecret("")
        .setOAuthAccessToken("")
        .setOAuthAccessTokenSecret("")
        .setJSONStoreEnabled(true);

    TwitterFactory tf = new TwitterFactory(cf.build());
    Twitter twitter = tf.getInstance();

    Query query = new Query("hello world");
    query.setCount(5);

    try {
        QueryResult result = twitter.search(query); 
        List<Status> tweets = result.getTweets();
        String jsonString = TwitterObjectFactory.getRawJSON(tweets.get(0));
        System.out.println(jsonString);
        OEmbed embed = TwitterObjectFactory.createOEmbed(jsonString);
        System.out.println(embed.getHtml());
    } catch(TwitterException e) {
        e.printStackTrace();
    }
}

凭据已被删除，但它们在程序中是正确的。控制台输出如下。

我确实得到了原始 JSON 字符串，但由于某种原因 createOEmbed 方法不喜欢它。堆栈跟踪如下。

JSONObject["html"] not found.

在尝试获取推文的 html 之前，您必须使用 OEmbedRequest 对象。

示例:

String url = ""

//gets url from id of tweet

OEmbedRequest oEmbedRequest = new OEmbedRequest("tweet id goes here", url);

//embeds into html code to be viewed  

OEmbed embed = twitter.getOEmbed(oEmbedRequest);  

//html result code

System.out.print(embed.getHtml());
