vue+router路由跳转不起作用怎么办

Vue.use(Router)
export default new Router({
mode:'history',
routes: [
   { path: '/', component: Login },
   { path: '/login', component: Login },
   { path: '/register',component: Register},
   {path: '/*', component: NotFound},
    ]
})

const history = require('connect-history-api-fallback');
 
// 在静态页面之前，这一句：app.use('/static', express.static(__dirname + '/public'))之前设置history
const historyConfig = {
 index: '/index.html'
};
app.use(history(historyConfig));
