在AngularJS中添加header不工作

Question

我是AngularJS的新手，我试图在所有请求中添加http头，但是它不起作用。我实际上是想通过.config把它们加进角度

我的代码是：

 angular.module('sc.app',[])
    .provider('TokenHandler',['$q',function ($q) {
        return {
            $get: function () {
                return {
                    request: function (config) {
                        var defer = $q.defer();
                        console.log('jwt');
                        config.defaults.headers.common['Authorization'] = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';
                        config.defaults.headers.common['Accept'] = 'application/json;odata=verbose';

                        return defer.resolve(config);
                    },
                    requestError: function (err) {
                        var defer = $q.defer();
                        return defer.reject(err);
                    },
                    response: function (success) {                            
                   var defer = $q.defer();
                    console.log(success)
                    return defer.resolve(success);
                },
                responseError: function (err) {
                    var defer = $q.defer();
                    return defer.reject(err);
                }
            };
        }
    }
}])

.config(['$httpProvider','TokenHandler',function ($httpProvider,TokenHandler) {
    $httpProvider.interceptors.push('TokenHandler');
}])

.service('TokenService',['$http','$localStorage',function ($scope,$localStorage) {
    $scope.getToken=function () {
        return $localStorage.gaid;
    }

    $scope.setToken=function (token) {
        $localStorage.gaid=token;
    }
}]);

我在谷歌上搜索了很多，但我无法解决其中的问题。即使我也尝试添加了config.headers选项，但也不起作用。

我的请求头是

当通过配置添加标头时，您只需要config.headers，例如-

config.headers['Authorization'] = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';
config.headers['Accept'] = 'application/json;odata=verbose';

只有在通过$http服务添加时，您才需要其他服务，例如-

 $http.defaults.headers.common.Authorization = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';

编辑:另一种尝试将以下内容添加到.service块的方法-

.service('TokenService',['$http','$localStorage',function ($scope,$localStorage) {  
     var service = this;

    service.request = function(config) {
        config.headers['Authorization'] = 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==';
        config.headers['Accept'] = 'application/json;odata=verbose';

        return config;
    };
