centos – 无法使用内置CA捆绑包来验证GoDaddy SHA2 SSL证书

我遇到了一个有趣的问题.我们有一个 PHP脚本,它与LTL托运人联系( https://facts.dohrn.com/).该脚本失败,因为它无法验证SSL证书.我去了网站,发现他们使用的是GoDaddy SHA2证书(使用 GoDaddy Certificate Bundles – G2,这是用于SHA2的).

我安装了最新版本的ca-certificate,看起来他们有Go Daddy Root Certificate Authority-G2,但这并不是一回事,并且在所有形式的验证中都失败了.我终于通过复制捆绑包并直接在CURL请求中使用它来使其工作.但这只是一种解决方法.是否还有其他我无法在没有直接安装CA的情况下完成这项工作？

似乎 https://facts.dohrn.com/处的Web服务器不包含中间证书.

这似乎是他们的配置错误.这绝对是可以预期会导致兼容性问题的因素,因为您实际上只应该依赖具有预先存在根证书的客户端.

请参阅证书链,例如来自SSLLabs result :(您还会注意到SSL设置存在许多其他问题.)

我会说你的主要选择是要么试图说服服务提供商修复他们的服务,要么通过向客户端提供他们的服务器应该提供的证书来解决问题.
