尝试使用FQL阅读Facebook中的朋友链接:为什么有些朋友返回一个空集? [英] Trying To Read Friends Links in Facebook Using FQL: Why do some friends return an empty set?

问题描述

当试图寻找也使用此应用程序并具有特定站点链接的我的朋友时，我没有从某些朋友那里得到任何结果，但对其他朋友来说效果很好.如果我使用Graph API Explorer，则执行/friendid/links之类的简单操作将返回一个空集.但是，我可以走到他们的墙上，查看链接，并且他们具有授予我的应用程序的read_stream权限.

When trying to find friends of mine that also use this app and have links from a specific site, I'm getting no results from some friends, but it works great on others. If I use the Graph API Explorer, doing something as simple as /friendid/links returns an empty set. However, I can go to their wall and see links and they have the read_stream permissions granted to my app.

值得注意的是，他们似乎也有不同的隐私设置"体验(完全不同的屏幕集).

Of note, they appear to have a different Privacy Settings experience as well (completely different set of screens).

有人见过吗?如何授予Facebook权限，但不能真正获得它们?

Anyone ever seen this? How can Facebook be granted permissions, but not really get them?

推荐答案

这与您尝试访问其数据的朋友的隐私设置有关. Facebook允许您设置不同级别的数据，这些数据将与您的朋友已安装的应用程序共享.默认情况下，我的链接"的隐私设置处于选中状态，但是我认为包括我在内的很多人都将其关闭.

It's all to do with the privacy settings of the friend you are trying to access data about. Facebook allows you to set different levels of data that will be shared with apps that have been installed by your friends. By default, the privacy setting is ticked for "My Links", but I imagine that a LOT of people, including me, will have turned this off.
