1. angular默认的请求头:
其中,Accept 和 X-Requested-With是$http自带的默认配置
Accept:application/json,text/plain 接受的请求的数据类型: json 文本
X-Requested-With: XMLHttpRequest 请求是通过XMLHttpRequest对象发送的
2. 修改默认请求头:
(1) 全局修改(整个模块)
使用$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()
});

*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.
