我在$urlRouterProvider.otherwise中使用它时,$rootScope是未定义的.
我的目标是检查用户当前是否登录,在登录期间我在rootScope上设置变量.
有趣的是,如果我让$rootScope成为第一个参数,那么我开始得到$injector的错误.
$urlRouterProvider.otherwise(function ($injector,$location,$rootScope) {
console.log("Otherwise Executed");
try {
var $state = $injector.get("$state");
toastr.options.positionClass = "toast-top-full-width";
toastr["error"]($location.$$path + ",Page not Found,names are case sensitive !");
toastr.options.positionClass = "toast-top-right";
if (typeof $rootScope.currentUser === 'undefined')
$state.go("Login");
else
$state.go("dashboard"); //redirect to a 404 page
} catch (e) {
return "/login"
}
});
解决方法
来自urlRouter源代码
* @param {string|object} rule The url path you want to redirect to or a function
* rule that returns the url path. The function version is passed two params:
* `$injector` and `$location` services,and must return a url string.
*
* @return {object} `$urlRouterProvider` - `$urlRouterProvider` instance
*/
this.otherwise = function (rule) {
使用var $rootScope = $injector.get(“$rootScope”);
