在Docker容器內的nginx上重定向到https

我正在嘗試在 https 上的 Docker 容器內的 NGINX 上運行 Blazor WASM 應用程式。當我在瀏覽器中鍵入 https://localhost:8021 （8021 是從埠 443 映射的）時，站點會正確加載。我還想從 http://localhost:8020 （8020 從埠 80 映射）重定向到以前的 https 地址。但無論我如何配置我的 nginx.conf，重定向都會轉到完全奇怪的 URL https://2f81239fe704/。誰能看到我在這里做錯了什么？

nginx.conf

events { }

http {
    include mime.types;

    server {
        listen 80;
        listen 443 ssl;
        
        server_name _;
        
        if ($scheme = http) {
            return 301 https://$host$request_uri;
            # except $host I also tried localhost:8021/443, 127.0.0.1:8021:443,
            # host.docker.internal:8021/443, nothing seems to work

        }
        
        ssl_certificate /https/localhost.crt;
        ssl_certificate_key /https/localhost.rsa;
        
        location / {
            root /usr/share/nginx/html;
            try_files $uri $uri/ /index.html =404;
        }
    }
}

在 nginx.conf 中創建兩個 diff 物件而不是一個

一個用于埠 80，另一個用于 443。

例子：

server {
    listen       80;

    server_name  _;

    location / {
        root /usr/share/nginx/html;
        try_files $uri $uri/ /index.html =404;
    }
}

server {
    listen       443 ssl;

    server_name  _;

    ssl_certificate /https/localhost.crt;
    ssl_certificate_key /https/localhost.rsa;

    location / {
        root /usr/share/nginx/html;
        try_files $uri $uri/ /index.html =404;
    }
}

我修改了你的檔案，你需要為你的域指定一個 $server_name 變數

events { }

http {
    include mime.types;

    server {
        listen 80;
        listen 443 ssl;
        
        server_name www.foo.bar;
        
        if ($scheme = http) {
            return 301 https://$server_name$request_uri;
            # except $host I also tried localhost:8021/443, 127.0.0.1:8021:443,
            # host.docker.internal:8021/443, nothing seems to work

        }
        
        ssl_certificate /https/localhost.crt;
        ssl_certificate_key /https/localhost.rsa;
        
        location / {
            root /usr/share/nginx/html;
            try_files $uri $uri/ /index.html =404;
        }
    }
}

我設法找到了解決方案。我猜是瀏覽器快取了我對 https://2f81239fe704/ （這是 docker 容器主機名）的第一個不正確的重定向回應，并且我的任何 nginx.conf 更改都沒有真正產生任何影響。清理 cookie 和站點資料后，對 nginx.conf 的更改實際上會生效。最后，我結束了：

server_name localhost;
        
if ($scheme = http) {
    return 301 https://localhost:8021$request_uri;
}
