qtwebkit - 使用 QT 为 SSL 制作自定义根证书存储时出现问题？

Question

我正在使用 QWebView 在 Qt 中开发我的自定义浏览器，并且我正在尝试制作我自己的可信证书的根证书存储，这些证书是从 mozilla 项目中获取的。

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 所需的所有根证书设置到我的商店。

谁能指导我？

您无法连接的原因是因为2F:DF:BC:F6:AE:91:52:6D:0F:9A:A3:DF:40:34:3E:9A当您连接到 www.gmail.com 时向您提供的 SSL 证书（带有 serial ）是为不同的域 - www.google.com 颁发的。这与根 CA 证书存储无关，因为无需根 CA 证书即可将证书的主题 CN 字段与您尝试连接的主机进行比较。您可以通过调用忽略此错误和其他 SSL 错误。 为了避免此错误，您可以直接连接到https://mail.google.com ，这是您尝试连接到https://www.gmail时被重定向到的域.com
void QNetworkReply::ignoreSslErrors () [virtual slot]

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。线路 B1 或线路 B2 必须同时处于活动状态。如果您想查看默认（系统）根 CA 证书存储会发生什么，您可以评论 A 行。此代码使用了两个证书；CA 的序列号证书30:00:00:02应该放在一个名为的文件中ThawteSGCCA.crt，而 CA 的序列号证书70:BA:E4:1D:10:D9:29:34:B6:38:CA:7B:03:CC:BA:BF应该放在一个名为BuiltinObjectToken-VerisignClass3PublicPrimaryCertificationAuthority.crt.
