nginx proxypass 重写基本 URL

Question

我正在尝试设置 Nginx 以使用 proxy_pass 将请求转发到多个后端服务。

其中一些不支持在子文件夹下访问，因此我必须添加重写以剥离附加的子文件夹，以允许从同一端口访问它们。

关于改进重写的任何提示？

我们可以将您rewrite的字符串 ( /internal)((?:/.*|))变得更难看，而不允许意外匹配..（如果您愿意，您会想要斜线所在的位置或类似的野兽）但丑陋的可维护性较差。

我倾向于说这样做：

location /internal {
    rewrite           ^/internal$ https://example.net/internal/ permanent;
    rewrite           ^/internal/(.*) /$1 break;
    proxy_pass        http://localhost:8081/internal;
    include proxy.inc;
}
