1. angular Default request header :

among ,Accept and X-Requested-With yes $http Built in default configuration

Accept:application/json,text/plain         The data type of the request accepted : json Text

X-Requested-With: XMLHttpRequest     Request is through XMLHttpRequest Object

2. Modify the default request header :

(1) Global modification ( The whole module )

Use $httpProvider rely on

        var myApp = angular.module('MyApp',[]);



             // modify / operation $httpProvider.defaults.headers.common Object to change $http Default request header configuration for 


* Be careful , You can only operate  $httpProvider.defaults.headers.common It works , Direct manipulation $httpProvider.defaults.headers It's invalid .

(2)   Specific request modification ( Some http request )

Directly in $http(config) Of config In the parameter headers Item to configure



<!DOCTYPE html>
<html ng-app = 'HttpGet'>
<title>18.2 $http(1)</title>
<meta charset="utf-8">
<script src="angular.js"></script>
<script src="script.js"></script>
<div ng-controller = "dataController">


var express = require('express');
var app = express();
app.use(express.static(__dirname+'')); var data = 'angularjs Medium $http.get'; app.get('/api/user',function(req,res){
}); app.listen(3000);

(1). adopt $httpProvider For the whole module $http Request header to modify :

var httpGet = angular.module('HttpGet',[]);
    // After deletion, there is no more... In the request header  X-Requested-With  attribute 
delete $httpProvider.defaults.headers.common['X-Requested-With'];
    // Add... To the request header Authorization The attribute is 'code_bunny'  
$httpProvider.defaults.headers.common['Authorization'] = 'code_bunny';
return function(){
var defer = $q.defer();
return defer.promise
$scope.data = getData()

(2). adopt $http(config) Of config Parameter to configure the request header of the request :

var httpGet = angular.module('HttpGet',[]);
return function(){
var defer = $q.defer();
headers: {'Authorization':'code_bunny'} // The request header will add Authorization The attribute is 'code_bunny'
return defer.promise
$scope.data = getData()

* notes : The book says it can be done through $httpProvider.defaults.headers.get['DNT']='1', To set not to track user browsing information , But after the actual attempt, it was found that the report was wrong .
