使用 nginx 重写 URL

Question

好吧，我使用 Ngix 作为反向代理，在后端使用 wso2。我想要做的是：在 NGIX 上使用自定义 URL 访问 wso2 的页面，但在后端访问正确的 URL。当我访问时的示例https://myngix/wso2am/publish，它应该发送到后端地址https://localhost:9443/发布，但我想保留我的 URL 作为https://myngix/wso2am/publish。这可能吗？这里，我有一个示例，我尝试实现这一点，但没有成功：

upstream sslapi.am.wso2.com {
    server {node-ip-address}:9443;
}

upstream sslgw.am.wso2.com {
    server {node-ip-address}:8243;
}

server {
    listen 80;
    server_name api.am.wso2.com;
    rewrite ^/(.*) https://api.am.wso2.com/$1 permanent;

}

server {
    listen 443;
    server_name api.am.wso2.com;
    proxy_set_header X-Forwarded-Port 443;
    ssl on;
    ssl_certificate /etc/nginx/ssl/{cert_name};
    ssl_certificate_key /etc/nginx/ssl/{key_name};
    location /wso2am {
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_read_timeout 5m;
            proxy_send_timeout 5m;
            proxy_pass https://sslapi.am.wso2.com/publisher;
        }

        access_log /etc/nginx/log/am/https/access.log;
        error_log /etc/nginx/log/am/https/error.log;
}

server {
    listen 443;
    server_name gw.am.wso2.com;
    proxy_set_header X-Forwarded-Port 443;
    ssl on;
    ssl_certificate /etc/nginx/ssl/{cert_name};
    ssl_certificate_key /etc/nginx/ssl/{key_name};
    location / {
            proxy_set_header X-Forwarded-Host $host;
            proxy_set_header X-Forwarded-Server $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_read_timeout 5m;
            proxy_send_timeout 5m;
            proxy_pass https://sslgw.am.wso2.com;
        }

        access_log /etc/nginx/log/gw/https/access.log;
        error_log /etc/nginx/log/gw/https/error.log;
}
