Angularjs 根据条件重定向到某个路由
我正在编写一个小AngularJS应用程序，它有一个登录视图和一个主视图，配置如下：Angularjs 根据条件重定向到某个路由,angularjs,ngroute,Angularjs,Ngroute,我正在编写一个小AngularJS应用程序，它有一个登录视图和一个主视图，配置如下： $routeProvider .when('/main' , {templateUrl: 'partials/main.html', controller: MainController}) .when('/login', {templateUrl: 'partials/login.html', controller: LoginController}) .otherwise({redirectTo:
$routeProvider
.when('/main' , {templateUrl: 'partials/main.html', controller: MainController})
.when('/login', {templateUrl: 'partials/login.html', controller: LoginController})
.otherwise({redirectTo: '/login'});
function LoginController($scope, $location, $rootScope) {
$scope.attemptLogin = function() {
if ( $scope.username == $scope.password ) { // test
$rootScope.loggedUser = $scope.username;
$location.path( "/main" );
} else {
$scope.loginError = "Invalid user/pass.";
}
}
http://localhost/#/main。。。等待我能听听路线的变化吗？无论如何，我会发布这个问题并继续查找。在深入阅读了一些文档和源代码之后，我想我已经找到了工作。也许这对其他人有用 我在模块配置中添加了以下内容：
angular.module(...)
.config( ['$routeProvider', function($routeProvider) {...}] )
.run( function($rootScope, $location) {
// register listener to watch route changes
$rootScope.$on( "$routeChangeStart", function(event, next, current) {
if ( $rootScope.loggedUser == null ) {
// no logged user, we should be going to #login
if ( next.templateUrl != "partials/login.html" ) {
// not going to #login, we should redirect now
$location.path( "/login" );
}
}
});
})
奇怪的是，我不得不测试部分名称（
login.html您可以试用一个工作演示并查看演示源。我也一直在尝试这样做。在与同事合作后，提出了另一个更简单的解决方案。我在
$location.path（）$scope.$watch(function() { return $location.path(); }, function(newValue, oldValue){
if ($scope.loggedIn == false && newValue != '/login'){
$location.path('/login');
}
});
我用拦截器。我已经创建了一个库文件，可以添加到index.html文件中。这样，您就可以对rest服务调用进行全局错误处理，而不必单独关心所有错误。接下来，我还粘贴了我的基本身份验证登录库。在那里你可以看到，我还检查了401错误并重定向到另一个位置。请参见lib/ea-basic-auth-login.js lib/http错误处理.js
