如何将缩略图张贴给Facebook / links对象？ [英] how does one post a thumbnail picture to a Facebook /links object?

问题描述

发布到/ feed的工作不正常，不适用于发布到/链接。虽然没有产生错误，并且我得到一个ID回来指示成功，但我指定为picture = http：//site/url/photo.gif的缩略图不显示。这是我使用的命令：

What works fine for posting to a /feed does not work the same for posting to /links. While no error is generated, and I get an ID back indicating success, the thumbnail I specified as "picture=http://site/url/photo.gif" does not show up. Here is the command I used:

curl -F \
     "picture=http://tycho.usno.navy.mil/gif/moons/m146.gif" \
     -F "message=How I look tonight to my worshippers on Earth" \
     -F "name=Current Moon Phase" \
     -F "link=http://www.calculatorcat.com/moon_phases/phasenow.php" -F caption="How the Moon appears tonight" \
     -F "access_token=111111111111111|2222222222222222222222222|33333333333333333333456n" \
     "https://graph.facebook.com/215958041750734/links"

现在，相同的数据，但发布到月球的墙壁（饲料），按预期工作：

Now, the same data, but published to The Moon's wall (feed), works as expected:

curl -F \
     "picture=http://tycho.usno.navy.mil/gif/moons/m146.gif" \
     -F "message=you're looking great tonight!" \
     -F "name=Current Moon Phase" \
     -F "link=http://www.calculatorcat.com/moon_phases/phasenow.php" -F caption="How the moon appears tonight" \
     -F "access_token=111111111111111|2222222222222222222222222|33333333333333333333456n" \
     "https://graph.facebook.com/215958041750734/feed"

两者的结果可以在Facebook月球页面的6月13日的帖子中看到： https://www.facebook.com/pages/The-Moon/215958041750734

The results of both can be seen in the June 13 posts on the Facebook "The Moon" page: https://www.facebook.com/pages/The-Moon/215958041750734

任何方式可以将缩略图显示在月球自己的帖子/链接？

Any way to get the thumbnail picture to show up on The Moon's own post to /links?

推荐答案

从实验中可以看出，picture =选项（如果存在）被忽略。它从页面本身拉一个缩略图，如果有任何图像恰好在它上面;否则不能显示缩略图。作为解决方法，可以在自己的控制下，框架集或iframe中将所需内容嵌入到服务器上，并将所需的缩略图嵌入到该页面中，将该链接发布到所需的Facebook ID /链接对象。

From experimentation, it turns out that the "picture=" option, if present, is ignored. It pulls a thumbnail from the page itself, if any images happen to be on it; otherwise no thumbnail can be displayed. As a workaround, one could embed the desired content on a server under his own control, in a frameset or iframe, and embed the desired thumbnail in that page, posting that link to the desired facebook id's /links object.
