1. angular默认的请求头:
其中,Accept 和 X-Requested-With是$http自带的默认配置
2. 修改默认请求头:
(1) 全局修改(整个模块)
使用$httpProvider依赖
var myApp = angular.module(‘MyApp‘,[]); myApp.config(function($httpProvider){ console.log($httpProvider.defaults.headers.common) //修改/操作$httpProvider.defaults.headers.common对象的属性以改变$http的默认请求头配置
})
*注意,只能操作 $httpProvider.defaults.headers.common 才有效,直接操作$httpProvider.defaults.headers是无效的.
(2) 特定请求修改(某个http请求)
直接在$http(config)的config参数中的headers项进行配置
demo:
html:
<!DOCTYPE html> <html ng-app = ‘HttpGet‘> <head> <title>18.2 $http(1)</title> <meta charset="utf-8"> <script src="angular.js"></script> <script src="script.js"></script> </head> <body> <div ng-controller = "dataController"> <span>{{data}}</span> </div> </body> </html>
nodejs:
var express = require(‘express‘); var app = express(); app.use(express.static(__dirname+‘‘)); var data = ‘angularjs中的$http.get‘; app.get(‘/api/user‘,function(req,res){ res.send(data) }); app.listen(3000);
(1).通过$httpProvider对整个模块的$http请求头进行修改:
var httpGet = angular.module(‘HttpGet‘,[]); httpGet.config(function($httpProvider){
console.log($httpProvider.defaults.headers)
//删除后请求头里不再有 X-Requested-With 属性 delete $httpProvider.defaults.headers.common[‘X-Requested-With‘];
//为请求头添加Authorization属性为‘code_bunny‘
$httpProvider.defaults.headers.common[‘Authorization‘] = ‘code_bunny‘;
}); httpGet.factory(‘getData‘,function($http,$q){ return function(){ var defer = $q.defer(); $http({ method:‘get‘, url:‘/api/user‘ }).success(function(data,status,headers,config){ defer.resolve(data); }).error(function(data,status,headers,config){ defer.reject(data) }); return defer.promise } }); httpGet.controller(‘dataController‘,function($scope,getData){ $scope.data = getData() });
(2).通过$http(config)的config参数对该请求的请求头进行配置:
var httpGet = angular.module(‘HttpGet‘,[]); httpGet.factory(‘getData‘,function($http,$q){ return function(){ var defer = $q.defer(); $http({ method:‘get‘, url:‘/api/user‘, headers: {‘Authorization‘:‘code_bunny‘} //请求头里会添加Authorization属性为‘code_bunny‘ }).success(function(data,status,headers,config){ defer.resolve(data); }).error(function(data,status,headers,config){ defer.reject(data) }); return defer.promise } }); httpGet.controller(‘dataController‘,function($scope,getData){ $scope.data = getData() });
完整代码地址:
*注: 书上说到可以通过$httpProvider.defaults.headers.get[‘DNT‘]=‘1‘,来设置不追踪用户浏览信息,但实际尝试后发现是报错的.
