Facebook rss - 如何增加大拇指图片大小？ [英] facebook rss - how to increase thumbs image size?

问题描述

我正在通过

  http://www.facebook.com/feeds/page访问facebook-rss。 php？format = rss20& id = ... 
  

更新：网址：

  http://www.facebook.com/feeds/page.php?format=rss20&id=170589069647190 
  

然而，图像的拇指是小的。是否可以使用rss-arg或FB页面设置来更改滚筒的大小？

（或者我应该以另一种方式获取FB文章） p>

敬意，

解决方案

您应该使用 Facebook Graph API ，它更加强大，多功能，更好地维护。

1. 从 / PAGE_ID / feed 端点开始，所以在你的例子中 / 170589069647190 /进料。 （在浏览器中进行测试）很好，现在你有相同的帖子列表那个RSS提要。请注意，每张具有照片的帖子都有一个 object_id 字段。


2. 对于每个 object_id ，转到端点 / OBJECT_ID？fields =图像，高度，宽度，源。如果您正在执行其中的多个操作，最好将它们批处理效率

这两个简单的步骤将为每张照片状态更新提供这些数据。外部高度，宽度和源是原始上传尺寸和来源。但是，图像数组为您提供了一堆调整大小的图像。选择最符合您需求的一种。

I'm accessing a facebook-rss through 
http://www.facebook.com/feeds/page.php?format=rss20&id=...
Update: Actual URL:
http://www.facebook.com/feeds/page.php?format=rss20&id=170589069647190
However, the thumbs for the images are way to small. Is it possible to change the size of the tumbs with rss-arg or FB-page setting?

(or should I get the FB-posts in another way)

regards,
解决方案
You should use the Facebook Graph API for this, it's far more robust, versatile, and better maintained.

Start at the /PAGE_ID/feed endpoint, so in your example /170589069647190/feed. (Play around in the explorer to test it) Great, now you have the same list of posts as that RSS feed. Note that each post with a photo has an object_id field. 
For each object_id, go to the endpoint /OBJECT_ID?fields=images,height,width,source. If you're doing multiple of them, it's best to batch them together for efficiency
Those 2 simple steps will give you this data for each photo status update. The outside height,width and source are the orginial upload dimensions and source. But the images array provides you with a bunch of resized images. Choose the one most appropriate for your needs.
