"no-referrer-when-downgrade error" Angular Firebase 上的应用连接到 NGINX Jelastic

Question

我有以下架构：

在 Google Firebase (HTTPS) 上托管的 Angular 网络应用程序
一个充满活力的环境：
- 一个 NGINX 服务器 (HTTPS)
- 一个 Springboot 2 应用服务器 (HTTP)

为了正常工作，Firebase 需要使用 HTTPS API，所以我向 NGINX 服务器添加了一个 SSL 证书和一个 public IP。如果我使用来自邮递员的 HTTP 调用 API，则调用工作正常。但是，如果我从 firebase 中的 Angular 应用程序调用 API HTTPS，它就不起作用，我会收到此错误："Referrer Policy: no-referrer-when-downgrade" - net::ERR_CONNECTION_REFUSED.

我看到了个问题，但我无法解决问题。

这是 nginx 配置文件。我用 XXX.XXX.XXX.XXX

替换了 IP 地址

您应该添加：

add_header 'Referrer-Policy' 'origin';

到/etc/nginx/conf.d/ssl.conf
