使用 twitter4j 从 Twitter 获取视频 url

Question

有没有人可以帮我用 twitter4j 在 twitter post 中找到视频 url？

我无法通过 getExtendedMediaEntities() 方法找到视频 url。

编辑：

ExtendedMediaEntity[] extendedMediaEntities = status.getExtendedMediaEntities();
                        for (int i = 0; i < extendedMediaEntities.length; i++) {
                            ExtendedMediaEntity extendedMediaEntity = extendedMediaEntities[i];
                            System.out.println("extendedMediaEntity type : "+extendedMediaEntity.getType());
                            String url = extendedMediaEntity.getURL();
                            System.out.println("extended url: "+ extendedMediaEntity.getMediaURL());
                        }

谢谢

您将需要使用 ExtendedMediaEntities 上的 Variant 来检索视频 URL。这将为您提供多种格式的多个 URL。 getExpandedURL() 会给你直接 url 到视频 post。

请在下面找到使用变体的示例：

    Paging paging = new Paging();
    paging.setCount(200);

    List<Status> statuses = twitter.getHomeTimeline(paging);
    for (Status status : statuses) {
        MediaEntity[] media = status.getMediaEntities();
        ExtendedMediaEntity[] extendedMediaEntities = status.getExtendedMediaEntities();
        for (int i = 0; i < extendedMediaEntities.length; i++) {
            ExtendedMediaEntity extendedMediaEntity = extendedMediaEntities[i];
            ExtendedMediaEntity.Variant[] variant = extendedMediaEntity.getVideoVariants();
            if (extendedMediaEntity.getType().equals("video")) {
                for (int j = 0; j < variant.length; j++) {
                    System.out.println("variant url: " + variant[j].getUrl());
                }
                String url = extendedMediaEntity.getURL();
                System.out.println("extended url: " + extendedMediaEntity.getExpandedURL());
            }
        }
    }

这将给出如下输出：

variant url: https://video.twimg.com/amplify_video/829771724442959873/pl/jKd0KfMseDh88K0s.m3u8 variant url:
