AngularJS ui路由器强制参数

Question

根据文档,angularjs ui-router url参数默认是可选的.那么有没有办法创建强制参数？就像参数丢失或为null时,它不会进入页面？

希望您能够帮助我.

谢谢

使用UI路由器解析以检查路由参数是否丢失.

//Example of a single route
.state('dashboard', {
  url: '/dashboard/:userId',
  templateUrl: 'dashboard.html',
  controller: 'DashboardController',
  resolve: function($stateParams, $location){

    //Check if url parameter is missing.
    if ($stateParams.userId === undefined) {
      //Do something such as navigating to a different page.
      $location.path('/somewhere/else');
    }
  }
})
