检查用户是否有权访问特定状态 [英] Check if user has permission to access specific states

问题描述

我使用 angular-permission 并且我想检查用户是否可以访问特定状态.

I use angular-permission and I want to check if user has access to specific states.

我的状态配置:

    $stateProvider
        .state('app', {
            url: '/',
            abstract: true,
            data: {
                permissions: {
                    only: ['BASE']
                }
            }
        })

是否有一种方法或某些东西可以在控制器中使用来确定它?

Is there a method or something which I can use in controllers to determine it?

// somewhere in controller
if (Permission.hasAccessToState('app')) {
    // I want to check if user has access to state without navigating to it
};

如果有人感兴趣，这里是相应的github上的讨论.

推荐答案

我在文档 wiki 中没有找到任何内容.但根据来源和评论，似乎有一个 Authorization 服务可用，您可以利用它.

I did not find something in the documentation wiki. But according to the source and comment there seems to be an Authorization Service available which u can take advantage of.

//inject PermissionMap and Authorization    
App.controller('Controller',function(PermissionMap,Authorization,$scope) {

     //get the state by name an assign it to `state`
      var permissionMap = new PermissionMap(state.data.permissions);

      var authorizationResult = Authorization.authorize(permissionMap);

      authorizationResult
        .then(function () {
          //authorized
        })
        .catch(function (rejectedPermission) {
          //unauthorized
        });
});

更新

在你的回复之后，我更深入地研究了代码.也许我们需要 StatePermissionMap 和 StateAuthorization.

After ur reply, i looked deeper into the code. Maybe we need StatePermissionMap and StateAuthorization instead.

 var statePermissionMap = new StatePermissionMap(state);

  StateAuthorization
      .authorize(statePermissionMap)
      .then(function () {
         //authorized
      })
      .catch(function (rejectedPermission) {
        //unauthorized
      })
