Question

angularJS 怎么实现拦截器

Answer 1

.config(function($stateProvider, $urlRouterProvider, $locationProvider, $httpProvider,$provide) {
$urlRouterProvider
.otherwise('/');
$locationProvider.html5Mode(true);
$httpProvider.interceptors.push('authInterceptor');
})
.factory('authInterceptor', function($rootScope, $q, $cookies, $injector) {
var state;
return {
// Add authorization token to headers
request: function(config) {
config.headers = config.headers || {};
if ($cookies.get('token')) {
config.headers.Authorization = 'Bearer ' + $cookies.get('token');
}
return config;
},
// Intercept 401s and redirect you to login
responseError: function(response) {
if (response.status === 401) {
(state || (state = $injector.get('$state'))).go('login');
// remove any stale tokens
$cookies.remove('token');
return $q.reject(response);
}
else {
return $q.reject(response);
}
}
};
