nginx proxy_pass 在 http 上有效但在 https 上失败

Question

当我传递http:localhost:9000给 proxy_pass 时，它正常工作。但是当我传递时https:localhost:9000，它失败了

proxy_pass http://localhost:9000有效和proxy_pass https://localhost:9000失败

这是意料之中的。

在正常情况下，你根本无法同时运行 HTTP和同一端口上的 HTTPS 服务。

您首先需要将监听端口 9000 的服务更改为 HTTPS 而不是 HTTP，然后 proxy_pass https://localhost:9000才能工作，或者使服务的 HTTPS 版本在其他端口上可用，然后使用 HTTPS 连接到该新端口。

但无论如何，这都不需要发生。使用 TLS 保护本地主机服务根本没有任何安全优势（甚至会降低性能）。只需终止 nginx Web 服务器上的 TLS 连接，然后继续与本地主机端口 9000 建立普通 HTTP 连接即可。
