我可以在用户的​​墙上发布全尺寸照片吗？

Question

我尝试使用Graph API：

https://developers.facebook.com/tools/explorer?method=GET&path=BillGates%2Fposts

但它返回（在标记picture下）一张小尺寸照片。如何以更大的尺寸获取该照片的链接？我可以吗？

Answer 1

根据https://developers.facebook.com/docs/reference/api/post/，我认为你没有想要直接获得更大照片尺寸的帖子。

但你可以从帖子的'object_id'获取Photo对象本身，类型为'photo'，然后从那里获取所有图片大小：https://developers.facebook.com/tools/explorer?method=GET&path=10151450339221961

然后它应该具有照片的所有可用图像尺寸的图像属性：
