angularjs http设置headers (用户唯一识别 token )

Posted 2020-09-21 Cynthia娆墨旧染

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);
}])
