Facebook javascript sdk api share a link and have an image of size 154 on the wall
提问by igrek
I need to share a link to facebook and have an image on the wall of bigger size. I share a link as follows:
我需要分享一个到 facebook 的链接，并在更大尺寸的墙上放一张图片。我分享一个链接如下：
FB.ui(
{
method : 'feed',
name: 'the name whatever',
caption: 'some caption',
description: 'description',
link: 'http://mysite.com/some_page',
picture: photo_url
},
function (response) { ... }
);
The picture is bigger then 154x154, i tried size 180x180 (i read somewhere in the docs it's required 180x180), but it ends up of size 90x90 on the wall anyway :(.
图片比 154x154 大，我试过尺寸为 180x180（我在文档中的某处读到它需要 180x180），但无论如何它最终在墙上的尺寸为 90x90 :(。
If i remove the picture parameter the image will be taken of the og:image meta tag, but it is still 90x90 pixels! If i post the link myself i can see it grabs the correct size - so when i post to wall myself it posts image of size 154x154, but how can i do the same to post it via the api facebook provides?
如果我删除图片参数，图像将被 og:image 元标记拍摄，但它仍然是 90x90 像素！如果我自己发布链接，我可以看到它获取了正确的大小 - 所以当我发布到自己的墙时，它会发布大小为 154x154 的图像，但是我该如何通过 facebook 提供的 api 发布它呢？
Tried it this way as well - works the same, please help :(
也以这种方式尝试过 - 效果相同，请帮忙:(
FB.api('/me/feed', 'post',
{
link : 'http://whatever_mysite.com/some_page',
picture : photo_url
},
function (response) { ... }
);
This is when posted manually, a direct link to a site(image taken off the meta tags):
这是手动发布时，指向站点的直接链接（从元标记中删除的图像）：
This is when shared via api(original: http://www.dandybooksellers.com/acatalog/TheoryTest.jpg):
这是通过 api 共享时（原文：http: //www.dandybooksellers.com/acatalog/TheoryTest.jpg）：
When no "picture" argument is provided it posts the "TEST IMAGE" from meta tags, but still with the size 90x90
当没有提供“图片”参数时，它会从元标记中发布“测试图像”，但大小仍为 90x90
