生成和安装Self-Signed Certificate
这么做又会遇到新的问题，浏览器再次报Certificate错误。
借助ChatGPT查了一番发现了问题所在，原来Certificate里是指定了域名的，而develop这个域名不在Projector自动生成的cert里，所以浏览器报错了。Cert里的这个东西叫做SAN（Subject Alternative Name）。
Subject Alternative Name Missing The certificate for this site does not contain a Subject Alternative Name extension containing a domain name or IP address.
Certificate Error There are issues with the site's certificate chain (net::ERR_CERT_COMMON_NAME_INVALID).
运行完就会生成证书cert.pem 和 私钥key.pem，运行下面的命令可以查看cert的信息：
1
openssl x509 -in cert.pem -noout -text
如果cert没问题，应该可以看到SAN如下：
1 2 3 4
X509v3 extensions: X509v3 Subject Alternative Name: DNS:develop, DNS:projector, DNS:localhost, IP Address:192.168.8.100, IP Address:192.168.5.211, IP Address:127.0.0.1
实际在浏览器中，也可以看到一个网站的证书详情，点击URL左边的锁，点Connection is secure，再点里面的证书图标就可以了，知道了这个可以更方便的排查问题。比如Google的证书：
