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 == ) {
// 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);
}])
如果你的代码并未做拆分，可以直接在config里面写拦截器
$httpProvider.interceptors.push(['$q','$injector','$localStorage',function ($q,$injector,$localStorage) {
var httpInterceptor = {
'responseError' : function(response) {
// todo...
return $q.reject(response);
},
'response' : function(response) {
if (response.status == ) {
// console.log('do something...');
}
return response || $q.when(response);
},
'request' : function(config) {
config.headers = config.headers || {};
if ($localStorage.token) {
config.headers.ut = $localStorage.token; //把你登录接口返回给你的token存到$localStorage里面，在这里取就好了
// config.headers['X-Access-Token'] = $localStorage.token;
};
return config || $q.when(config);
// return config;
},
'requestError' : function(config){
// todo...
return $q.reject(config);
}
};
return httpInterceptor;
}]);
