Error message

未指定 redirect 参数，也未配置 homeRoute 路由，无法完成重定向操作

What it means

Thrown on the sso-server when a user opens /sso/auth directly in the browser: the request has no redirect parameter and no homeRoute has been configured. With nowhere to send the user after login, the server cannot complete the flow and aborts.

Solutions

1. Configure a fallback landing page on the server: sa-token.sso.server.home-route=/system/index (or sa-token.sso.home-route depending on version)
2. Enter the SSO flow through a client app so the redirect parameter is present, instead of opening /sso/auth directly

Example fix

# before (application.yml on sso-server)
sa-token:
  sso:
    server: {}   # no home-route

# after
sa-token:
  sso:
    home-route: /system/index

String redirect = req.getParam(paramName.redirect);
if(SaFoxUtil.isEmpty(redirect) && SaFoxUtil.isEmpty(cfg.getHomeRoute())) {
    // render a friendly page instead of letting the auth endpoint throw
}

When it happens

Trigger: Browser navigates to http://sso-server.com/sso/auth without a redirect query parameter while sa-token.sso.server.home-route is unset; typically a user bookmarked the login endpoint or opened it manually instead of being redirected from a client.

Common situations: First-time setup where the SSO server login page URL is visited directly; load balancer health checks hitting /sso/auth; missing home-route in application.yml for a deployment that expects direct logins.
