在对到达端口 8331 和 8332 的所有请求应用 ssl 之后，我编写了一个重定向到 tomcat 端口 8330 的代码。

但是问题是如果这样通过nginx去访问8330的话GET https://serverIP:8330/itf/subscribe net::ERR_SSL_PROTOCOL_ERROR会出错。

当 nginx 不存在时，/itf/subscribe 正常工作。

但是在https地址内部调用的时候好像有问题。

我想知道如何解决这个问题。

此致！

答案1

根据您的 nginx 配置，端口 8330 由您的上游服务器 (Tomcat) 处理。如果您尚未将 Tomcat 配置为使用 SSL，则当您使用 URL 连接到它时将收到 SSL 错误https。

根据您的配置，您需要连接到https://example.com:8332/以使用 SSL。这将连接到为 SSL 配置的 nginx 端口，然后 nginx 将请求代理到 Tomcat 服务器。

答案2

我遇到了同样的错误。

首先，当我使用 SSL 访问我的 IP/域时，我看到了我的路由器的登录页面。这是因为它也在端口 443 上提供自己的网页。

我的解决方案是将端口 443 从任何地址转发到我的服务器 IP：443（端口转发规则已添加到我的路由器）。

Source: *   Port: 443   TO    Destination: server-IP   Port: 443

这解决了我的问题。
