angular用拦截器统一处理http请求和响应实例代码

想使用angularjs里的htpp向后台发送请求,现在有个用户唯一识别的token想要放到headers里面去，也就是{headres:{'token':1}}

index.html里引入以下js:

angular.module('app.factorys',[])
    .factory('httpInterceptor',['$q','$injector','$localStorage',function ($q,$injector,$localStorage) {var httpInterceptor = {'responseError' : function(response) {// ......return $q.reject(response);
            },'response' : function(response) {if (response.status == 21000) {// console.log('do something...');                }return response || $q.when(response);
            },'request' : function(config) {
                config.headers = config.headers || {};if ($localStorage.token) {
                    config.headers.token = $localStorage.token;// config.headers['X-Access-Token'] = $localStorage.token;                };return config || $q.when(config);return config;
            },'requestError' : function(config){// ......return $q.reject(config);
            }
        };return httpInterceptor;
    }])

在app里注入factory后，在config里面配置

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