有一个用户crud页面，当保存一个新用户时，url需要用用户保存的id参数改变。我不知道发生了什么，但是当调用this.router.navigate（['/ user'，user.id]）时会发生错误。跟随路由器和组件发生错误的代码。Angular 5 router.navigate错误

地址创建一个新用户 http://localhost:4200/user

地址更新用户 http://localhost:4200/user/38

//route config 
    const routes: Routes = [ 
    { 
    path: ':id', 
    component: UserComponent, 
    resolve: { 
     user: UserResolve 
    } 
    }, 
    { 
    path: '', 
    component: UserComponent, 
    resolve: { 
     user: UserResolve 
    } 
    } 
] 
//component 
this.router.navigate(['/user', user.id])
