AngularJS ui 路由器必选参数 [英] AngularJS ui router mandatory parameters

问题描述

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呢?比如当参数缺失或者为空时就不会进入页面?

Based on the documentation, angularjs ui-router url parameters are by default optional. So is there a way to create mandatory parameters? Like when the parameter is missing or null it will not proceed to the page?

希望你能帮助我.

谢谢

推荐答案

使用 UI 路由器 resolve 检查路由参数是否丢失.

Use UI Routers resolve to check if route params are missing.

//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');
    }
  }
})
