google-chrome - 使用 SSL bump 时无法连接到真实站点 ssl 错误

Question

在我们的办公室，我们使用 squid 来限制用户仅连接特定的网站和 url。如果用户通过 https 连接网页，url_regex acl 将不起作用。在 https 请求中，我们只能控制域。但是我们需要限制 url 级别。因此，我们使用 ssl bump 来拦截 https 请求。它工作正常，但我们在浏览器中收到一些 ssl 警告。

是否可以在没有任何浏览器警告的情况下拦截 bump 中的 ssl 连接？

SSL bump 正在进行中间人攻击，浏览器对此进行了提示，这是预期的行为。如果您不想这样做，您需要将 CA (test.crt) 导入所有浏览器中作为受信任的。
