Nginx反代无法定义路径到AList服务

[everwisher]

AList docker运行正常，通过以下Nginx配置可从https://alist.mydomain.com正常访问：

```nginx
http {
  server {
    server_name alist.mydomain.com;
    listen 443 ssl reuseport;
    listen [::]:443 ssl reuseport;

    ssl_certificate           /etc/nginx/certs/alist.mydomain.com_ecc/fullchain.cer;
    ssl_certificate_key       /etc/nginx/certs/alist.mydomain.com_ecc/alist.mydomain.com.key;
    ssl_protocols             TLSv1.2 TLSv1.3;
    ssl_session_timeout       5m;
    ssl_ciphers               HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;

    location / {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header Range $http_range;
      proxy_set_header If-Range $http_if_range;
      proxy_redirect off;

      # Handle CORS
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
      add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';

      client_max_body_size 80000m;
      proxy_pass http://192.168.1.199:5201/;
    }
  }
}

我打算使用不同路径，分别代理到我自己的AList docker和小雅的AList docker（正常跑在http://192.168.1.199:5203/上），于是我修改了Nginx如下：

location ~ ^/myalist/(.*)$ {
      # The rest remains unchanged
      proxy_pass http://192.168.2.7:5201/$1;
    }

重启Nginx后，https://alist.mydomain.com/myalist 无法正常显示，浏览器中：

• GET https://alist.mydomain.com/myalist回报200
• alist.mydomain.com/assets/index.29d84749.js回报404
• alist.mydomain.com/assets/index.15d8d646.css回报404

两个回404的请求，Origin都是alist.mydomain.com而不是alist.mydomain.com/myalist，请求的文件也不在alist.mydomain.com/myalist中，请问如何调整Nginx配置？
