问为什么keycloak在页面刷新时变得未经授权？

EN

import * as Keycloak from 'keycloak-js';

const keycloakConfig = {
   url: 'https://smartgrid.doersops.com/auth/',
   realm: 'OneSmartgrid',
   clientId: 'smartgrid-react-web-admin',
}

const keycloak = new Keycloak(keycloakConfig);

export default keycloak

import React from 'react';
import { KeycloakProvider } from '@react-keycloak/web'
import keycloak from './keycloak';
import { AppRouter }  from './routes';
function App() {
  const token = localStorage.getItem('token');
  const refreshToken = localStorage.getItem('refreshToken');

  const setTokens = (token, idToken, refreshToken) => {
    localStorage.setItem('token', token);
    localStorage.setItem('refreshToken', refreshToken);
    localStorage.setItem('idToken', idToken);
  }
  return (
    <KeycloakProvider 
      keycloak={keycloak}
      onTokens={
          (tokens:  keycloakTokens) => 
          setTokens(tokens.token ?? '', tokens.idToken ?? '', tokens.refreshToken ?? '')
        }
      initOptions={{ onLoad: 'login-required', token, refreshToken }}
      >
      <AppRouter />
    </KeycloakProvider>
  )
}

export default App;
