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 Library 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将其与我当前的 Twitter4j 代码集成。Twitter 上传媒体 API 参考。
我搜索了我的解决方案，发现链接Posting a Status Update with an Image (gitHub)，但这个参考非常复杂，因为它基本上使用 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？
我通过使用 Twitter4j 3.0.4 和 Twitter4j 3.0.4 - 媒体库解决了我的问题。你可以点击这里下载

你可以尝试这样的事情：
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
