Facebook登录并发布权限回调不起作用。

}

我正在尝试在后台分享图片和文字到Facebook。首先，我会检查是否已经授予发布权限。如果没有，我会使用logInWithPublishPermissions来获取发布权限。但是由于某些原因，注册回调的响应总是在onCancel()中。我需要在logInWithPublishPermissions中添加什么吗？

我认为我需要先提交一份评论，以获得“发布操作”的权限。只有这样回调才能正常工作。 - CodeAssasins

我也遇到了相同的问题，但只发生在我的应用程序中特定的 Facebook 帐户上，其他帐户似乎都正常运行。 - zulkarnain shah

@zulkarnainshah。你能够发布到任何Facebook账户吗？ - CodeAssasins

是的，我是。只是在一个特定的账户上我无法发布。事实上，我从Facebook返回了503错误代码。 - zulkarnain shah

你能分享一下代码吗？我也会检查是否在任何账户中得到相同的错误代码。 - CodeAssasins

注释不允许粘贴长代码。 - zulkarnain shah

在Facebook开发者网站https://developers.facebook.com/上，您必须授予publish_actions权限。

请点击链接设置您的应用程序以访问publish_actions权限，并提交应用程序进行审查。
