无法在angularjs工厂内设置http默认值

Question

在我的Angularjs应用程序中，我有一个工厂，需要对用户进行身份验证。我正在使用httpProvider来设置默认值。但是我收到错误，说明$httpProvider未定义。

'use strict'; 
angular.module('myApp') 
.factory('authService', function ($q, $http, $rootScope, $window) { 
    return { 
     authenticateUser: function() { 
      ........ 
      ........ 
     $httpProvider.defaults.headers.common['Accept'] = 'application/json, text/javascript'; 
     $httpProvider.defaults.headers.common['Content-Type'] = 'application/json; charset=utf-8'; 

我然后在工厂的依赖

'use strict'; 
angular.module('myApp') 
.factory('authService', function ($q, $http, $rootScope, $window, httpProvider) { 
    return { 
     authenticateUser: function() { 
      ........ 
      ........ 
     $httpProvider.defaults.headers.common['Accept'] = 'application/json, text/javascript'; 
     $httpProvider.defaults.headers.common['Content-Type'] = 'application/json; charset=utf-8'; 

这一次，我收到Unknown provider: $httpProviderProvider <- $httpProvider <- authService

请让我知道我错了加入$httpProvider尝试。

你不能在工厂内的服务提供商是可访问的。

您可以使用interceptors为每个http请求添加默认值。

angular.module('myApp').config(function ($httpProvider) { 
    $httpProvider.interceptors.push('authInterceptorService'); 
}); 

angular.module('myApp').factory('authInterceptorService', ['$q', '$location', 'localStorageService', function ($q, $location, localStorageService) { 
var authInterceptorServiceFactory = {}; 
var _authentication = { 
    isAuth: false, 
    userName: "" 
}; 

var _request = function (config) { 
    config.headers = config.headers || {}; 
    var authData = localStorageService.get('data'); 
    if (authData) { 
     config.headers.Authorization = 'Bearer ' + authData; 
    } 

    return config; 
} 

authInterceptorServiceFactory.request = _request; 

return authInterceptorServiceFactory; 
}]);

$ httpProvider仅在配置像

angular.module('myApp') 
.config(function($httpProvider){ 
    $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8'; 
})
