如何从Facebook图形API获取大图像以进行视频 [英] How to get large image from facebook graph api for video

问题描述

https://graph.facebook.com/v2.7/1505552949567253?fields=source,length,picture.type(large),permalink_url&access_token=bla

但是我得到的图像很小，需要放大很多图像，从而导致质量下降，有没有办法我可以在请求中指定图像质量

But I am getting a very small image, which needs to be enlarged a lot thereby losing a lot of quality, is there a way that i can specify the picture quality as well in the request

响应就是这样

}

返回的图像很小

推荐答案

使用thumbnails字段并在is_preferred设置为true的情况下查找对象. picture不响应修饰符.

Use the thumbnails field and look for the object with is_preferred set to true. picture doesn't respond to modifiers.
