这是一个获得大图像的新方法。它是出生后的预览方法不起作用

  / ** 
 *返回一个大的url的Facebook 
 *适用于类型PHOTO 
 * @param图片
 * @param是一个帖子类型链接
 * @return url of image 
 * / 
 @ Transactional 
 public String getBigImageByFacebookPicture（String pictrue，Boolean link）{
 if（link&& pictrue.contains（url = http））{
 String url = pictrue.substring pictrue.indexOf（url =）+ 4）; 
 try {
 url = java.net.URLDecoder.decode（url，UTF-8）; 
} catch（UnsupportedEncodingException e）{
 StringBuffer sb = new StringBuffer（Big image for Facebook link not found：）; 
 sb.append（link）; 
 loggerTakePost.error（sb.toString（））; 
返回null; 
} 
 return url; 
} else {
 try {
 Document doc = Jsoup.connect（pictrue）.get（）; 
 return doc.select（＃fbPhotoImage）。get（0）.attr（src）; 
} catch（Exception e）{
 StringBuffer sb = new StringBuffer（Big image for Facebook link not found：）; 
 sb.append（link）; 
 loggerTakePost.error（sb.toString（））; 
返回null; 
} 
} 
} 
  

享受你的大图像:)

When loading the Facebook feeds from one page, if a picture exist in the feed, I want to display the large picture.

How can I get with the graph API ? The picture link in the feed is not the large one.

Thanks.

解决方案

This is a new method to get a big image. it was born after the previews method doesn't works

     /**
     * return a big url of facebook
     * works onky for type PHOTO
     * @param picture 
     * @param is a post type link
     * @return url of image
     */
    @Transactional
    public String getBigImageByFacebookPicture(String pictrue,Boolean link){
        if(link && pictrue.contains("url=http")){
            String url = pictrue.substring(pictrue.indexOf("url=") + 4);
            try {
                url = java.net.URLDecoder.decode(url, "UTF-8");
            } catch (UnsupportedEncodingException e) {
                StringBuffer sb = new StringBuffer("Big image for Facebook link not found: ");
                sb.append(link);
                loggerTakePost.error(sb.toString());
                return null;
            }
            return url;
        }else{
            try {
                Document doc = Jsoup.connect(pictrue).get();
                return doc.select("#fbPhotoImage").get(0).attr("src");
            } catch (Exception e) {
                StringBuffer sb = new StringBuffer("Big image for Facebook link not found: ");
                sb.append(link);
                loggerTakePost.error(sb.toString());
                return null;
            }
        }
    }

Enjoy your large image :)
