无法实现 Facebook Java API

Question

我需要有关 Facebook 营销 API 的帮助。 我正在尝试使用 Facebook Java API 创建广告。 我已将电子邮件存储在我的数据库中，我希望我的程序获取这些电子邮件 ID 并将它们推送到自定义受众中。但我面临“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。我尝试将链接提供给我想要推广的页面，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();

这里，xyz 是我的 facebook 页面的链接。我收到了这个错误。

我刚刚在某处看到 facebook 不允许 facebook 域链接减少垃圾邮件。所以我不明白要在那里传递什么。请帮帮我。 或者，如果有人能解释整个“广告创意”部分，那就太好了。

另外，我不明白“图像哈希”部分。请解释

谢谢。

来自docs：

您将无法再创建或编辑未连接到有效页面的事件广告和链接广告。请求会返回错误：ErrorCode::ADPRO2__AD_MUST_HAVE_PAGE (1885833)

还有：

如果您在广告素材的 object_story_id 或 object_story_spec 字段中提供有效的 actor_id，您仍然可以创建事件广告和链接广告
