不要显示＆＃39; s3.amazon.com＆＃39;将图像发布到LinkedIn API时

Question

我通过公共API将图像发布到LinkedIn，我的应用程序从我们的S3存储桶中提取图像。当更新出现在LinkedIn上时，它会显示＆＃39; s3.amazon.com＆＃39;在图像旁边。有什么方法可以防止这种情况发生吗？

Ruby代码：

 def post(message_body, attachment, post)
        options = { :visibility => { :code => 'anyone' } }
        if attachment.present?
          options.merge!(:content => { :title         => 'titles',
                                       :description   => 'descriptions',
                                       :submitted_url => 'http://s3.amazonaws.com/...'
                                     }, :comment => message_body)
        else
           options.merge!(:comment => message_body)
        end
        response = client.add_share(options)
        post.posted!
        JSON.parse(response.body)['updateUrl']
