og：描述未显示

Question

我更新了og：description标记以及this页面的其他标记。调试器在debugger中显示了这一点，但是当我在Facebook上分享它时，它也没有在预览中显示。什么可能出错？

Answer 1

我遇到了同样的问题：共享调试器预览信息中的所有内容看起来都不错（意味着所有图像和描述信息均显示正确），但是“链接预览”区域未显示页面的“描述”摘录（只是图片和标题）。

经过反复试验，我发现问题出在标题：显然Facebook的Inside backtrack iteration 1 1 does not exist in the current list and hence adding Inside backtrack iteration 2 2 does not exist in the current list and hence adding Inside backtrack iteration 3 3 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [1, 2, 3] 3 is deleted,making list back to [1, 2] 2 is deleted,making list back to [1] 3 does not exist in the current list and hence adding Inside backtrack iteration 3 2 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [1, 3, 2] 2 is deleted,making list back to [1, 3] 3 is deleted,making list back to [1] 1 is deleted,making list back to [] 2 does not exist in the current list and hence adding Inside backtrack iteration 2 1 does not exist in the current list and hence adding Inside backtrack iteration 3 3 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [2, 1, 3] 3 is deleted,making list back to [2, 1] 1 is deleted,making list back to [2] 3 does not exist in the current list and hence adding Inside backtrack iteration 3 1 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [2, 3, 1] 1 is deleted,making list back to [2, 3] 3 is deleted,making list back to [2] 2 is deleted,making list back to [] 3 does not exist in the current list and hence adding Inside backtrack iteration 2 1 does not exist in the current list and hence adding Inside backtrack iteration 3 2 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [3, 1, 2] 2 is deleted,making list back to [3, 1] 1 is deleted,making list back to [3] 2 does not exist in the current list and hence adding Inside backtrack iteration 3 1 does not exist in the current list and hence adding Inside backtrack iteration 4 Another List finalized [3, 2, 1] 1 is deleted,making list back to [3, 2] 2 is deleted,making list back to [3] 3 is deleted,making list back to [] 属性限制在63个字符左右（我是从数据库中动态获取标题数据，还有一些头衔很长）。一旦我将页面标题的长度限制为最大数量。大约63个字符，一切都很好！

你试过这样的吗？

<div class="row"> <table> <tr><td></td><td></td></tr> </table> </div>
