On the configuration of nginx for vue Project in production Environment

I set the reverse proxy code at the front end as follows

proxyTable: {
  "/API":{
    target: "http://dev.snhb.group:9090",
   // target: "192.168.31.110:9090",
    changeOrigin: true,
    secure: false,
    pathRewrite: {
      "^/API":"/"
    }
  }
},

:
export function listLineSelect() {
return request({
    url: "/API/pcms/pcms/alarm/listAllLine",
    method: "post",
    baseURL: "",
    params: {}
})

}

there is no problem with the development environment
but such problems are encountered in the production environment
Request URL: http://localhost:9090/API/pcms/security/sso/ajaxcheck?account=gmservice&password=123546
Request Method: POST
Status Code: 404
Remote Address: 127.0.0.1
Referrer Policy: no-referrer-when-downgrade

I want to become this request http://localhost:9090/pcms/security/sso/ajaxcheck?

so I tried to configure
server {

on nginx as follows

    listen       9090;
    server_name  localhost;

    -sharpcharset koi8-r;

    -sharpaccess_log  logs/host.access.log  main;
    
    location ~* /api/ {
        proxy_pass  http://dev.snhb.group:9090;
        root   html;
        index  index.html index.htm;
    }

doesn"t work. I don"t know if you have any good ideas. Thank you

listen 9090; // 9090 9000 server_name localhost; -sharpcharset koi8-r; -sharpaccess_log logs/host.access.log main; location / { root ""; index index.html index.htm; } -sharp-sharp-sharp location /API/ { // API proxy_pass http://dev.snhb.group:9090/; // /API/ proxy_redirect off; proxy_set_header Host $host; proxy_set_header X_Real_IP $remote_addr; proxy_set_header X_Forwarded_For $proxy_add_x_forwarded_for; proxy_connect_timeout 150; proxy_read_timeout 300; proxy_send_timeout 300; }
