due to the limitation of production environment, only one port can be opened 9988 . Projects written by others also use this port, so different request paths can only be used to distinguish different projects.

my project is separate from front to back. The content packaged on the page is placed in the server directory: / usr/local/m2m/nbMsg/browser/dist , the port of the java backend is 8989 , and the background interface is uniformly prefixed with / api/v1 .

I want to configure to access http://[host]:9988/nbmsg, which can return the html static page file under the / usr/local/m2m/nbMsg/browser/dist directory by default. Then all ajax requests on the page start with / api/v1 and need to be proxied to port 8989 .

here is my configuration. One server is the virtual host of the existing 9988 port, and the other virtual host of the 8999 port is added by me. How should I modify the configuration? Let the requests of http://[host]:9988/nbmsg be forwarded to the virtual host on the 8999 port?

server {
    listen 9988;
    root /server/html;
