问题描述
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
I've connected a custom domain to firebase hosting, you can see placeholder website here: 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，会看到不相关的域详细信息.这是正常现象吗?如果是这样，为什么会发生呢?如果不是，这是Firebase方面的错误吗?
At first glance everything seems to be fine, but when I view ssl certificate details I see unrelated domain details. Is this normal and if so why is it happening? If not is this a bug on firebase side?
推荐答案
这是正常现象，您应该转到详细信息"部分以查看整个证书内容.
This is normal, you should go to the "Details" part to see the whole certificate content.
您将看到证书具有主题备用名称"扩展名，在其中您会找到许多DNS名称，其中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的数量，特别是对于在同一IP上托管以不同名称命名的多个网站的服务器(如果检查，您将看到以下所有名称都解析为同一组IP)
You will see that the certificate has a "Subject Alternative Name" extension, in which you will find many DNS names, including one for your own website. The certificate applies in the same way to all websites in this list.This is done to reduce the number of certificates to handle, specifically for servers hosting multiple websites with different names on the same IPs (if you check you will see that all names below resolves to the same set of IPs)
您的浏览器接受它，因为它可以看到扩展名中的内容，并且可以看到您的网站.如果不是这样，您的浏览器会说该连接不安全，因为URL中的网站名称与证书中的内容之间的名称不匹配.
Your browser accepts it because it sees the content in the extension and it sees your website in it. If not, your browser would have say that the connection is insecure because there is a name mismatch between the website name in the URL and what is inside the certificate.
