目标应用程序资产未通过 nginx proxy_pass 加载

我有一个正在运行的基本 nginx 代理http://127.0.0.1:8080。

这是nginx.conf：

events {}
http { 
    server {
        listen 8080;
        server_name 127.0.0.1;
        rewrite_log on;
        error_log  /var/log/nginx/error.log notice;


        location / {
            proxy_pass http://127.0.0.1:5200;
            proxy_set_header  Host 127.0.0.1:5200;
        }
        location /api {
            proxy_pass http://127.0.0.1:8000;
            proxy_set_header  Host 127.0.0.1:8000;
        }
        location = /app2 {
            return 302 /app2/;
        }
        location /app2/ {
            proxy_pass http://127.0.0.1:5300/;
            proxy_set_header  Host 127.0.0.1:5300; 
        }

    }
}

点击 时http://127.0.0.1:8080/app2，会显示在端口上运行的应用程序5300，但资产未正确加载。我怀疑 nginx 正在将资产请求代理到在端口上运行的另一个应用程序5200，即location /。我停止了这个应用程序进行确认，这是来自 nginx 的日志（请注意，上游显示为 ，http://127.0.0.1:5200...但应该是http://127.0.0.1:5300...）

我看到类似的问题http://127.0.0.1:8080/api，资产未加载。我也尝试使用不同的正则表达式组合重写规则，但得到了类似的错误。

如何配置 nginx 以路由到不同的应用程序并正确加载其资产。

经过进一步的挖掘和测试，rewrite解决方案详述于https://stackoverflow.com/questions/62836801/nginx-reverse-proxy-how-to-serve-multiple-apps对我来说是有效的。

这是我添加到 nginx.conf 中的代码片段，用于正确加载 app2 的资产

if ($http_referer ~ https?://[^/]+/app2/(.*))
{
    # rewrite request URI only if it isn't already started with '/app2' prefix
    rewrite ^((?!/app2).*) /app2$1;
}
