Nginx 反向代理 静态文件404异常处理

A网站nginx反向代理B网站，问题在于B网站的静态地址访问路径为 /static/style/bootstrap.min.css
这样会导致静态文件访问变成了 A网站域名/static/style/bootstrap.min.css 实际上 bootstrap.min.css 属于B网站，于是404出现了

我以 /gongju/ 作为反向代理的识别
A网站nginx反向代理修改如下

location ^~ /gongju/ {proxy_pass         http://B网站/;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 $scheme;# 修复重定向路径proxy_redirect ~^/(.*)$ /gongju/$1;sub_filter_once off;sub_filter_types *;# 1. HTML/JS/CSS 常见路径格式sub_filter '="/'        '="/gongju/';sub_filter "='/"        "='/gongju/";sub_filter 'url(/'      'url(/gongju/';sub_filter 'url("/'     'url("/gongju/';sub_filter "url('/"     "url('/gongju/";sub_filter 'src="/'     'src="/gongju/';sub_filter "src='/"     "src='/gongju/";sub_filter 'href="/'    'href="/gongju/';sub_filter "href='/"    "href='/gongju/";sub_filter 'action="/'  'action="/gongju/';sub_filter "action='/"  "action='/gongju/";# 2.
