如何跳过HTTP请求的AngularJS拦截器？

我有一个 angularjs 应用程序，其中有一个拦截器，它将授权令牌添加到每个请求的标头中。

然而，在应用程序的某个地方，我需要使用外部 API，拦截器会破坏它，因为它添加了这个外部 API 提供者不接受的授权标头。如何让 angularjs HTTP 跳过拦截器，仅在这一特定情况下？

拦截器代码如下：

app.factory('authInterceptorService', ['$q', '$injector', '$location', 'localStorageService', function ($q, $injector, $location, localStorageService) {
    var authInterceptorServiceFactory = {};
    var $http;

    var _request = function (config) {

        config.headers = config.headers || {};

        var authData = localStorageService.get('authorizationData');
        if (authData) {
            //console.log("token: " + authData.token.substring(0, 10));
            //console.log("user: " + authData.userName);
            config.headers.Authorization = 'Bearer ' + authData.token;
        }
        return config;
    }

    var _responseError = function (rejection) {
        var deferred = $q.defer();
        if (rejection.status === 401) {
            var authService = $injector.get('authService');
            authService.refreshToken().then(function (response) {
                _retryHttpRequest(rejection.config, deferred);
            }, function () {
                authService.logOut();
                $location.path('/login');
                deferred.reject(rejection);
            });
        } else {
            deferred.reject(rejection);
        }
        return deferred.promise;
    }

    var _retryHttpRequest = function (config, deferred) {
        console.log('retrying');
        $http = $http || $injector.get('$http');
        $http(config).then(function (response) {
            deferred.resolve(response);
            //console.log("success:" +response);
        }, function (response) {
            deferred.reject(response);
            //console.log("error:" + response);
        });
    }

    authInterceptorServiceFactory.request = _request;
    authInterceptorServiceFactory.responseError = _responseError;

    return authInterceptorServiceFactory;
}]);

Easy

$http.get("url" , {noAuth : true}).then(success(),error());

在拦截器中

  var _request = function (config) {

    config.headers = config.headers || {};

    var authData = localStorageService.get('authorizationData');
    if (authData && !config.noAuth) {
        //console.log("token: " + authData.token.substring(0, 10));
        //console.log("user: " + authData.userName);
        config.headers.Authorization = 'Bearer ' + authData.token;
    }
    return config;
}
