无法实施Facebook Java APi

我需要Facebook营销API的帮助 . 我正在尝试使用Facebook Java API制作广告 . 我已将电子邮件存储在我的数据库中，我希望我的程序能够获取这些电子邮件ID并将其推送到自定义受众群体中 . 但我面临着“AdCreative”的一些问题 . 它有两个名为SetLinkUrl和SetObjectUrl的参数 . 我不明白在这些参数中传递什么 . 我尝试给链接页面我试图推广但它不起作用 .

对于AdCreative部分，这就是我正在做的事情 .

AdCreative creative = account.createAdCreative()
                  .setTitle("Java SDK Test Creative")
                  .setBody("Java SDK Test Creative")
                 //.setImageHash(imageFile.hashCode())
                 .setLinkUrl("xyz")
                 .setObjectUrl("xyz")
                  .execute();

在这里，xyz链接到我的Facebook页面 . 我收到了这个错误 .

我只是在某处读到Facebook不允许facebook域名链接减少垃圾邮件 . 所以我不明白该通过什么 . 请帮帮我 . 或者如果任何人都可以解释整个“AdCreative”部分，那就太棒了 .

另外，我不理解“图像哈希”部分 . 请解释

谢谢 .
