使用nginx代理服务swagger异常的问题?

Question

为了区分正式和测试环境, 部署了两个相同的java程序 地址分别是
http://127.0.0.1:8812
http://127.0.0.1:8813
base url是 /paiban
用nginx做代理
nginx配置文件这样写的

 # 排班
        location /paiban {
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header Host        $host;
                proxy_connect_timeout 3s;
                proxy_read_timeout 86400s;
                proxy_pass http://127.0.0.1:8812;
        }

 # 排班test
        location /paiban-test {
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header Host        $host;
                proxy_connect_timeout 3s;
                proxy_read_timeout 86400s;
                proxy_pass http://127.0.0.1:8813/paiban/;
        }
    

通过api访问一切正常

但是通过swagger访问 /paiban-test 总是问访问到/paiban

swagger的文件路径是正常的 其他接口就会访问到错的地址
