如何使用RestFB发布带有自定义缩略图的视频？

<dependency>
    <groupId>com.restfb</groupId>
    <artifactId>restfb</artifactId>
    <version>2.27.1</version>
</dependency>

FacebookClient facebookClient = new DefaultFacebookClient("YOUR_ACCESS_TOKEN");

byte[] thumbnailBytes = Files.readAllBytes(Paths.get("path_to_thumbnail_image"));

FacebookType thumbnailResponse = facebookClient.publish("me/videos", FacebookType.class,
        BinaryAttachment.with("thumbnail.jpg", thumbnailBytes),
        Parameter.with("published", false));

byte[] videoBytes = Files.readAllBytes(Paths.get("path_to_video_file"));

FacebookType videoResponse = facebookClient.publish("me/videos", FacebookType.class,
        BinaryAttachment.with("video.mp4", videoBytes),
        Parameter.with("thumb", thumbnailResponse.getId()),
        Parameter.with("published", false));

String videoId = videoResponse.getId();
facebookClient.publish(videoId, Boolean.class, Parameter.with("published", true));
