$location.path 在使用 AngularJS 的工厂中不会改变 [英] $location.path doesn't change in a factory with AngularJS

问题描述

我的工厂看起来像:

'use strict';

angular.module('myApp')
  .factory('httpInterceptor',['$q','$location', '$rootScope', function($q, $location, $rootScope){
    return {
      response: function(response) {

        if(response.success === false) {
console.log("Redirecting");
            $location.path('/login');
            return $q.reject(response);
        }

        return response || $q.when(response);
      }
    }
}]);

它会吐出日志，但不会更改路径.我该怎么做才能做到这一点?

It spits out the log, but doesn't change the path. What can I do to make this happen?

推荐答案

$location 的文档 说:

请注意，setter 不会立即更新 window.location.相反，$location 服务知道作用域生命周期，并在作用域 $digest 阶段将多个 $location 突变合并为一个对 window.location 对象的提交".

Note that the setters don't update window.location immediately. Instead, the $location service is aware of the scope life-cycle and coalesces multiple $location mutations into one "commit" to the window.location object during the scope $digest phase.

因此，如果拒绝承诺对 $location 有影响，那么您可能看不到预期的更改.

Hence, if the rejection of the promise has an effect on $location, then you may not see the intended change.

要强制在 angular 生命周期之外进行更改，您可以使用 window.location 设置 hash，然后强制重新加载页面.当然，这将停止执行随后的任何代码并清除会话，但如果用户未登录，这可能是您想要的.

To force a change outside of the angular life-cycle, you can set the hash using window.location and then force a reload of the page. This will, of course, stop execution of any code which follows and erase the session, but that might be what you want if the user is not logged in.
