我正在为我的网站创建一个php网络聊天应用程序，它是用php和js html构建的，当它被用于http（在安全连接中）但当我使用时，它工作正常（有一些小烦恼和需要更新）使用https它询问加载不安全脚本（系统的主要js），我不想要，我试图将其更改为wss：//但现在我没有得到任何连接，网站有两个主要部分页面和服务器，页面如下

这在http中工作得很好但在https中不起作用是否有任何人可以帮助解决这个问题并使其在https系统上运行而不必点击会在说不安全之后允许它的内容？
答案 0 :(得分：0)
显然，它永远不会通过SSL，因为您的代码不支持SSL。您只是打开一个原始套接字并通过一个不安全的套接字发送/接收。 SSL在套接字层之上作为安全层发生，因此名称为 SSL 。您无法从通过安全连接加载的页面降级到通过不安全连接加载资源。浏览器根本不允许这样做就是为了破坏使用安全连接的目的。
简单的解决方法是在您的websocket服务器前面放置一个支持SSL的反向代理，并在代理级别进行SSL终止。 HAProxy是一个可以支持websockets的反向代理。
更复杂的修复，实在太广泛，无法在此详细解释，实际上是在应用程序级别（即在PHP中）进行SSL终止。这部分需要你进行大量的研究和努力，如果你刚刚开始学习这些东西，我真的不会建议。
