var deferred = $injector.get('$q').defer();
switch(rejection.status){
case 401:
console.log('401');
if(inFlight == null){
var authService = $injector.get('oauthService');
inFlight = authService.refreshToken() //this is just a $http call
}
inFlight
.then(function (response) {
_retryHttpRequest(rejection.config, deferred)
.success(function (result) {
deferred.resolve(result);
})
.error(function(err, status) {
deferred.reject(err);
})
.finally(function() {
inFlight = null;
});
$injector.get('oauthService').setLocalStorageData(response.data);
},
function (err, status) {
$injector.get('oauthService').logOut();
});
break;
}
return deferred.promise;
}
var _retryHttpRequest = function (config, deferred) {
var $http = $http || $injector.get('$http');
return $http(config);
}
authInterceptorServiceFactory.request = _request;
authInterceptorServiceFactory.responseError = _responseError;
return authInterceptorServiceFactory;
}
它几乎可以工作,第一个401响应发出“refreshToken”请求,然后所有后续请求都与新令牌一起重新发送。 我面临的问题是在行
deferred.resolve(result);
虽然结果是预期的对象,但是当调用promise函数时,它的参数是未定义的!
承诺函数
sidebarService.getMenu()
.success(sidebarReady)
.error(sidebarReadyError);
function sidebarReady(items) {
//when errorInterceptor catches the error
//and re-sends, when it resolves this funciton, argument is undefined
//
}
有人可以帮忙吗? 谢谢

只需使用.then()而不是.success(),它自Angular 1.5以来已被弃用,并在1.6中删除。使用.success()承诺链接是不可能的,因为它不会返回新的解决承诺。

事实证明使用.then()代替.success()有效! 谢谢@Nekudotayim
还要感谢@Ben和@Nikolay
