Twitter Card验证工具

预览任意URL在Twitter/X上分享时的显示效果。验证所有Twitter Card元标签。

如何使用本工具

1
Paste the full public URL (including https://) of the page you want to inspect.
2
Run the tool so the server fetches the page and parses its HTML head.
3
Read the status banner: green means card, title, and description were all found; red means at least one is missing.
4
Scan the tag table and the rendered card preview to see exactly which twitter: values came back and which show as missing.

Twitter（现称X）使用带有twitter:前缀的元标签，在URL被分享时呈现富媒体卡片。最常见的类型是summary_large_image，它会显示大图、标题、描述和来源。本工具会提取并验证每一个Twitter专属标签，然后渲染出卡片，让你看到受众将会看到的效果。

Confirm a new blog post exposes twitter:card, twitter:title, and twitter:description before you publish it.
Debug why a shared link shows a bare URL instead of a rich card by spotting which required tag is missing.
Check that twitter:card is set to summary_large_image when you expect the wide-image layout rather than a small thumbnail.
Verify a twitter:image URL actually loads by viewing it in the rendered card preview.
Audit a competitor or reference page to see how they configure their five core twitter: tags.
Spot-check a staging or production deploy to catch templates that dropped the twitter: meta tags during a build.
