Question

我正在使用QWebView和Qt在Qt中开发自定义浏览器我正在尝试创建自己的受信任证书的根证书存储库，这些证书来自mozilla项目。

我使用QSslSocket :: setDefaultCaCertificates（）来覆盖默认证书。但是我无法加载https://www.gmail.com，就像在mozilla中一样。

我已将gmail的所有必需的根证书设置到我的商店。

任何人都可以指导我吗？

您无法连接的原因是因为当您连接到www.gmail.com时向您呈现的SSL证书（带有序列2F:DF:BC:F6:AE:91:52:6D:0F:9A:A3:DF:40:34:3E:9A）是针对其他域发布的 - www.google.com。这与根CA证书存储无关，因为不需要根CA证书来将证书的Subject CN字段与您尝试连接的主机进行比较。您可以通过调用
来忽略此错误和其他SSL错误 void QNetworkReply::ignoreSslErrors () [virtual slot]
为避免此错误，您可以直接连接到https://mail.google.com，当您尝试连接到https://www.gmail.com

时，这是您要重定向到的域

下面是一个工作示例，它将向您显示确切的SSL错误和QNAM级别错误。线B1或线B2必须同时有效。如果要查看默认（系统）根CA证书存储区发生的情况，可以对A行进行注释。此代码使用了两个证书;具有序列30:00:00:02的CA证书应放在名为ThawteSGCCA.crt的文件中，并且带有序列70:BA:E4:1D:10:D9:29:34:B6:38:CA:7B:03:CC:BA:BF的CA证书应放在名为BuiltinObjectToken-VerisignClass3PublicPrimaryCertificationAuthority.crt的文件中。

使用QT为SSL制作自定义根证书存储区的问题？
