SSL证书验证结果：无法获取本地颁发者证书（20）

Question

我正在尝试使用Windows 8在Heroku上添加SSL证书。我指的是Heroku的ssl-endpoint文章来添加它。一切正常，直到最后一步，但是当我进入

curl -kvI https://www.example.com

它说

SSL certificate verify result: unable to get local issuer certificate (20), continuing anyway.

这是完整的输出：

怎么了 先感谢您。

Answer 1

我合并了两个 SSL 证书，然后将其上传到 heroku。结合两个 SSL 证书的命令是：

cat certificate.crt gd_bundle.crt > combine.crt

它将结合certificate.crt并gd_bundle.crt创造combine.crt
