angular js在每个http请求$ http上添加请求参数 [英] angular js add request parameter on every http request $http

问题描述

我想使用angular $ http与api进行交互，但是我需要将我的身份验证令牌存储到$ http，以便在每个请求中发送删除，我希望令牌存在，我也有看到人们在标题中放置令牌，我知道如何将它放在标题中，但我不确定将标记放入标题是否是一个好习惯，这是我的配置：

I'd like to use angular $http to interact with api, but I need to store my auth token to $http so that in every request wether post get put delete, I want the token to be present, also I have seen people place tokens in the header , I know how to place it in the header, but I'm not sure if its a good practice to put tokens in the header , here is my config :

config(['$stateProvider', '$urlRouterProvider','$http', function($stateProvider, $urlRouterProvider, $http) {
  $urlRouterProvider.otherwise("/view1");

}]);

推荐答案

要与需要令牌身份验证的API进行通信，需要设置一个拦截器。

To communicate with an API that requires token authentification, you need to set up an interceptor.

在你的配置文件中：

function config(..., $httpProvider) {
    $httpProvider.interceptors.push('authInterceptor');
    ...
}
angular
    .module('app')
    .config(config);

authInterceptor是一个工厂，负责为所有$ http请求添加标头：

authInterceptor is a factory that will take care of adding headers to all your $http requests:

function authInterceptor($rootScope, $q, $window) {
    return {
        request: function (config) {
            config.headers = config.headers || {};
            if ($window.sessionStorage.token) {
                config.headers.Authorization = 'Bearer ' + $window.sessionStorage.token;
            }
            return config;
        },
        responseError: function (rejection) {
            if (rejection.status === 401) {
                console.log("not authorised");
            }
            return $q.reject(rejection);
        }
    };
};

angular
    .module('app')
    .factory('authInterceptor', authInterceptor);

令牌可以来自sessionStorage，cookies或任何东西。

The token can come from sessionStorage, cookies or anything.
