角度UI路由器设置网站入口点.重定向到主URL [英] Angular UI-router set website entry point. Redirect to home URL

问题描述

我正在将Angular与UI-router一起使用，我希望用户始终(或在大多数情况下，为简洁起见，我们可以总是说总是")进入步骤1，即我的主页上的Web应用程序.

UI路由器配置简写:

.config(function($stateProvider, $urlRouterProvider) {

    // route to root if no valid route found
    $urlRouterProvider.otherwise('/step1');

    var step1 = {
        name : 'step1',
        url : '/step1',
        templateUrl: 'partials/step1.html'
    };
    var step2 = {
        name : 'step2',
        url : '/step2',
        templateUrl: 'partials/step2.html'
    };
    .
    .
    .
    .
}

我可以做一个解析或指定一个控制器，只需设置$ location.path('/step1')，但是有一种方法可以只设置一个入口点，并且只有从步骤1，而无需进行重定向的费用?
预先感谢

解决方案

要解决此问题，您还可以使用$ stateChangeStart事件.

$rootScope.$on('$stateChangeStart',
function(event, toState, toParams, fromState, fromParams){
  if (fromState.name === '' && toState.name !== 'state1'){
    event.preventDefault();
    $state.go('state1');
  }
});

UI-router config shorthand:

.config(function($stateProvider, $urlRouterProvider) {

    // route to root if no valid route found
    $urlRouterProvider.otherwise('/step1');

    var step1 = {
        name : 'step1',
        url : '/step1',
        templateUrl: 'partials/step1.html'
    };
    var step2 = {
        name : 'step2',
        url : '/step2',
        templateUrl: 'partials/step2.html'
    };
    .
    .
    .
    .
}

I can do a resolve or specify a controller and simply set $location.path('/step1'), but is there a way to just set one entry point and have the step2 / step3 urls be only reachable after starting from step1, without the cost of a redirect?
Thanks in advance

解决方案

To solve this problem you can also use $stateChangeStart event.

$rootScope.$on('$stateChangeStart',
function(event, toState, toParams, fromState, fromParams){
  if (fromState.name === '' && toState.name !== 'state1'){
    event.preventDefault();
    $state.go('state1');
  }
});
