AngularJS 在每个请求上设置 header

Question

我正在尝试设置 header 以在每个请求上发送访问 token 。这是我尝试过的:

.factory("TokenRestangular", "StorageService", function (Restangular, StorageService) {
    return Restangular.withConfig(function (RestangularConfigurer) {


        // Set access token in header.
        RestangularConfigurer.setDefaultHeaders({Authorization:'Bearer '+ StorageService.get("access_token")});
        RestangularConfigurer.setBaseUrl('/api');
    });
})

我得到错误:

Error: [ng:areq] http://errors.angularjs.org/1.2.19/ng/areq?p0=fn&p1=not%20aNaNunction%2C%20got%string

我认为你的工厂函数传递了太多参数，试试这个:

    .factory("TokenRestangular", function (Restangular, StorageService) {
        return Restangular.withConfig(function (RestangularConfigurer) {
        // Set access token in header.
        RestangularConfigurer.setDefaultHeaders({Authorization:'Bearer '+ StorageService.get("access_token")});
        RestangularConfigurer.setBaseUrl('/api');
    });
})

或

    .factory("TokenRestangular", ["Restangular", "StorageService", function (Restangular, StorageService) {
        return Restangular.withConfig(function (RestangularConfigurer) {
        // Set access token in header.
        RestangularConfigurer.setDefaultHeaders({Authorization:'Bearer '+ StorageService.get("access_token")});
        RestangularConfigurer.setBaseUrl('/api');
    });
}])

如果你想要安全的缩小代码。
