angular学习笔记(二十四)-$http(2)-设置http请求头

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 = http://www.mamicode.com/‘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.
