我正在制作 facebook 应用程序，上传形成的图像.. 一切都很酷.. 但我没有得到任何东西来标记随机的人，我正在将该名称附加到该图像上...

只需告诉我如何在照片上标记一个人:)

是的，我很确定这不起作用，你只是一种“无效内容”或类似的错误；除非图形 API 已更新，否则无法通过 API 添加照片标签。您唯一能做的就是上传图像，添加“标签”按钮并将用户重定向到 Facebook 上的图像，在那里他们可以手动标记它，例如这里：http://o2-academy.vccphub.com/snapbooth.php/snapbooth/image/2012-01-21-032244-o2ac1-1740164044-8972579
