如何在 Nginx 中将 url /id/slug (WordPress) 重写为 slug (Ghost)？

Question

我正在尝试从 WordPress 迁移到自托管的 Ghost 博客。在此过程中，我希望将我的 post 的 url 从 https://example.com/categoryid/slug 清理到 https://example.com/slug。 Cateogryid 似乎是包含 1-4 位数字的整数。

问题是我还有 url 不想重写

不要为 img 重写：https://example.com/content/images/2020/01/logo.png
为 post 重写：https://example.com/1886/slug

我试过的：
这有效，但对于 url 的

rewrite ^(.*)(\/\d*\/)(.*)$ https://example.com/ redirect;

这应该与在线正则表达式测试器相匹配，但不起作用

rewrite \.*(com)(\/\d*\/)(.*)$ https://example.com/ redirect;

重写规则前后传递代理

location /content/ {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $http_host;
    proxy_pass example_ip ;
}

完整配置：

server {
    listen 80;
    listen [::]:80;
    server_name         www.example.com example.com;

    if ($host = www.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

}

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


    # redirect /id/slug -> slug
    rewrite ^(.*)(\/\d*\/)(.*)$ https://example.com/ redirect;
    # redirect category -> tag
    rewrite (category\/)(.*)$ https://example.com/tag/ permanent;
    # redirect blog -> archive
    rewrite (blog\/)$ https://example.com/archive permanent;

    root /var/www/ghost/system/nginx-root; # Used for acme.sh SSL verification (https://acme.sh)
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
    include /etc/nginx/snippets/ssl-params.conf;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://example_ip;
    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;

}

在 URL https://example.com/content/images/2020/01/logo.png 和 https://example.com/1886/slug 中，rewrite 指令看到的 URI 分别是 /content/images/2020/01/logo.png 和 /1886/slug。

您需要重写第一个路径元素中包含 1 到 4 位数字的 URI。

使用其中之一：

rewrite ^/\d+(/.*)$  redirect;

或：

rewrite "^/\d{1,4}(/.*)$"  redirect;

最后一个变体必须使用引号来保护嵌入的大括号字符。
