Open Graph预览工具向您显示共享链接在发布之前会是什么样子,您输入您的 og:title、og:description、og:image、og:url 和 Twitter 卡字段 - 或粘贴您已有的元标签块 - 并且该工具会并排呈现 Facebook、X/Twitter、LinkedIn、Slack 和 Discord 的近似社交卡。您无需实时推送页面、共享页面并发现标题被切成两半或图像永远不会加载,而是在仍然可以修复它的同时看到问题。
Open Graph协议是几乎每个平台用来构建那些卡片的共享词汇,一个刮刀访问你的页面,读取<head>中的og:元标签,并从中组装一个预览,其中的捕获是每个平台对那些相同标签的渲染方式不同:X截断了大约110个字符的描述,而Facebook显示更接近155,LinkedIn将描述完全隐藏在某些表面上,Slack将所有内容折叠成一个紧凑的附件,一张卡片中看起来精细的字段可以在另一张卡片中损坏,这就是为什么一次预览所有这些是唯一可靠的检查。
该工具完全在您的浏览器中运行,不会对您的网站进行网络调用。它不会获取您的 URL 或抓取您的页面 - 它可以从您给它的标签中运行,要么输入表单,要么粘贴为原始 HTML 并进行本地解析。这意味着您可以验证登录后面的页面、暂存域上或根本未部署的页面的元数据,并且您输入的任何内容都不会上传。
填写 og:title、og:description、og:image、og:url 和 Twitter 卡片字段。 如果页面已经有元标记,将原始 HTML 粘贴到解析框中,工具会将每个识别的标签加载到表单中。
每个字段都根据实际平台限制获得通过、警告或失败状态:标题长度、X 和 Facebook 的描述长度、图像 URL 是否绝对和 HTTPS,以及您的句柄是否有效。
查看 Facebook、X 大图像、X 摘要、LinkedIn、Slack 和 Discord 卡片。 修剪您的标题或描述,直到每张卡片都清晰地读取,并确认图像以正确的纵横比加载。
复制完成的 <meta> 标签块并将其粘贴到您的页面头部,或将值输入框架元数据 API。 然后重新刮擦每个平台调试器中的 URL 以清除任何缓存的预览。
渲染近似的 Facebook、X(两种卡片样式)、LinkedIn、Slack 和 Discord 卡片,以便您可以发现中断的平台
放入一个页面头或一个松散的meta html块,内置的解析器加载每个OG: twitter:标记它直接识别到表单中
