从Javascript检测损坏的锁图标（混合安全/不安全内容）

我正在努力使一个网站在HTTPS下完全功能化。作为其中的一部分，我想确保我们永远不会“打破锁”。也就是说，我们永远不应该在SSL页面上加载非SSL内容，这可能会触发警告或其他指示，具体取决于浏览器。为了验证这种情况，我想做两件事：

编写Selenium测试，验证各种操作不会打破锁定

在JS中编写日志代码，在用户会话期间检查锁是否已损坏，如果已损坏，则返回到服务器

---

JS中是否有任何方法可用于检查浏览器HTTPS锁定图标的已断开/未断开状态？或者等效地，当前页面内容的混合/非混合状态？

您可以迭代整个DOM并检查所有链接，以确保它们是https://您无法从JavaScript本身检测到这一点，但您可以使用HTTP标头指示浏览器将混合内容的报告发送到服务器或第三方聚合服务

下面是一个CSP头的示例，它向第三方服务report-uri.io报告混合内容：

仅限内容安全策略报告：默认src https:；报告urihttps://report-uri.io/report/

由报表URI的维护者编写，它将更详细地介绍如何工作。如果愿意，您还可以将CSP头配置为报告到您自己的URL。

您可以使用我编写的PHP CLI脚本来扫描您的站点，以查找混合内容

从CLI运行此脚本，例如：

$ mixed-content-scan https://www.bram.us/

脚本本身将开始扫描，并在运行时提供反馈。当发现混合内容时，屏幕上将显示导致混合内容警告的URL：

$ mixed-content-scan https://www.bram.us/

还可以传入包含要扫描的URL列表的文件，并将输出更改为JSON。也支持忽略模式。

这是一个好主意，但不考虑XHR、JSONP和帧间RPC请求。这是一个庞大的代码库，很难在错误出现之前捕捉到错误，因此需要不断地进行测试和记录。
