nginx 实现不同路径转发不同端口

问题（目的）：同一服务器下，并存 java 和 node 项目，nginx 实现不同路径转发不同端口 希望的结果是：访问：fashion.goonie.cn/api/wxpay/ 和访问：fashion.goonie.cn:8080/wxpay/ 应该是一样的 我的配置:

# See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    upstream java{
        server fashion.xxxx.cn:8080;
    }
    upstream node{
        server fashion.xxxx.cn:3001;
    }

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location ^~ /api/ {
            proxy_pass http://java;
                proxy_redirect off;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Remote_addr $remote_addr;
        }

        location /* {
            proxy_pass http://node;
                proxy_redirect off;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Remote_addr $remote_addr;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
