推特，​​推特4j和圖像

Question

是否可以使用Twitter4J在推文中上傳多個圖像？

我在官方文檔中找不到任何東西。

謝謝。

Answer 1

您可以嘗試類似下面的內容，如果您有更多的圖片上傳，您可以使用循環或功能。

ConfigurationBuilder twitterConfigBuilder = new ConfigurationBuilder(); 
    twitterConfigBuilder.setDebugEnabled(true); 
    twitterConfigBuilder.setOAuthConsumerKey("consumerkey"); 
    twitterConfigBuilder.setOAuthConsumerSecret("consumersecret"); 
    twitterConfigBuilder.setOAuthAccessToken("accesstoken"); 
    twitterConfigBuilder.setOAuthAccessTokenSecret("accesstokensecret"); 

    Twitter twitter = new TwitterFactory(twitterConfigBuilder.build()).getInstance(); 
    String statusMessage = "Hey I am posting 2 images of xyz event"; 
    File imagefile1 = new File("/images/image_1.jpg"); 
    File imagefile2 = new File("/images/image_2.jpg"); 

    long[] mediaIds = new long[2]; 
    UploadedMedia media1 = twitter.uploadMedia(imagefile1); 
    mediaIds[0] = media1.getMediaId(); 
    UploadedMedia media2 = twitter.uploadMedia(imagefile2); 
    mediaIds[1] = media2.getMediaId(); 

    StatusUpdate statusUpdate = new StatusUpdate(statusMessage); 
    statusUpdate.setMediaIds(mediaIds); 
    Status status = twitter.updateStatus(statusUpdate);
