使用 Java 中的 Twitter API（版本 1.1）通过上传媒体发布状态

Question

我想知道如何使用 java 在 Twitter 上上传媒体来更新我的状态。目前，我的代码工作正常，不包括使用 Twitter4J 库 LINK 的媒体上传脚本，但我无法理解如何使用 twitter api 上传具有我的状态的媒体并使用我当前的 Twitter4j 代码对其进行集成。Twitter Upload Media API Reference .

我搜索了我的解决方案并找到了链接Posting a Status Update with an Image (gitHub)，但是这个参考非常复杂，因为它基本上是使用 PApplet。我想用没有扩展小程序类的普通 http 帖子来做。

在 JAVA 上显示带有媒体（图像）的发布状态的任何帮助/教程？

Answer 1

你可以试试这样的：

        String accesst = "ACCESS_TOKEN";
        String accessts = "TOKEN_SECRET";
        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.setOAuthAccessToken(accesst);
        builder.setOAuthAccessTokenSecret(accessts);
        builder.setOAuthConsumerKey("CLIENT_ID");
        builder.setOAuthConsumerSecret("CLIENT_SECRET");
        OAuthAuthorization auth = new OAuthAuthorization(builder.build());
        Twitter twitter_auth = new TwitterFactory().getInstance(auth);
        String screenName = twitter_auth.getScreenName();

        StatusUpdate status = new StatusUpdate("STATUS_TEXT");
        status.setMedia(new File("YOUR_FILE_PATH"));// BY SPECIFYING FILE PATH
        //status.setMedia("File name", new FileInputStream("")); // By InputStream
        Status updateStatus = twitter_auth.updateStatus(status);
        long id = updateStatus.getId(); // id of the status posted

从任何网址发布图片：

        String img_url = "http://www.qualitywallpapers.net/w/media/original/2013/02/23/Twitter-bird-logo-PNG.png";
        URL url1 = new URL(img_url);
        BufferedImage image = ImageIO.read(url1);
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        ImageIO.write(image, "image/png", os);
        InputStream is = new ByteArrayInputStream(os.toByteArray());
        status.setMedia("hello", is);// By Stream

我通过使用 Twitter4j 3.0.4 和 Twitter4j 3.0.4 - 媒体库解决了我的问题。可以通过click here下载
