nginx 反向代理重定向到 http 而不是 https

具有以下设置:NGINX(端口 443)>码头 (9090 端口) >弹簧控制器

Having the following setup: NGINX (Port 443) > Jetty (Port 9090) > Spring Controller

为了简化问题，我使用了以下文件:

For simplifying the problem I use the following files:

• /main.html 包含调用 spring 控制器的 iframe /test
• spring controller /test 做 return "redirect:/iframe.html";
• /iframe.html 带有简单的文字这是 IFrame"

使用 HTTP 没有问题，但在将 NGINX 配置切换到 HTTPS 后，我在浏览器中收到以下错误并且未显示 iframe:

With HTTP there is no problem but after switching the NGINX configuration to HTTPS I get the following error in the browser and the iframe is not displayed:

main.html:7 混合内容:https://dev/main.html"页面已通过 HTTPS 加载，但请求了不安全的帧'http://dev/iframe.html'.此请求已被阻止；这内容必须通过 HTTPS 提供.

main.html:7 Mixed Content: The page at 'https://dev/main.html' was loaded over HTTPS, but requested an insecure frame 'http://dev/iframe.html'. This request has been blocked; the content must be served over HTTPS.

所以控制器重定向到 http 而不是 https，这是我的 NGINX 配置，根据我的理解，它应该让码头/控制器知道它正在 https 上运行:

So the controller redirects to http instead of https, this is my NGINX configuration which from my understanding should let the jetty/controller know that it is running on https:

 server {
    listen 443      ssl http2;
    listen [::]:443 ssl http2;
    server_name dev;

    ssl on;
    ssl_certificate ...;
    ssl_certificate_key ...;

    location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Port $server_port;
        
        proxy_ssl_name $host;
        proxy_ssl_server_name on;

        proxy_pass http://127.0.0.1:9090;
    }
}
