Firebase 托管 ssl 证书显示不同的域

Question

我已将自定义域连接到 Firebase 托管，您可以在此处查看占位符网站： https : //asimetriq.com

乍一看，一切似乎都很好，但是当我查看 ssl 证书详细信息时，我看到了不相关的域详细信息。 这是否正常，如果是，为什么会发生？ 如果不是，这是 firebase 方面的错误吗？

Answer 1

这是正常的，您应该去“详细信息”部分查看整个证书内容。

您将看到该证书具有“主题备用名称”扩展名，您会在其中找到许多 DNS 名称，包括您自己网站的名称。 该证书以相同的方式应用于此列表中的所有网站。 这样做是为了减少要处理的证书数量，特别是对于在同一 IP 上托管具有不同名称的多个网站的服务器（如果您检查，您将看到下面的所有名称都解析为同一组 IP）

您的浏览器会接受它，因为它会看到扩展程序中的内容并会看到您的网站。 如果不是，您的浏览器会说连接不安全，因为 URL 中的网站名称与证书中的名称不匹配。
