Angularjs中$http以post請求通過消息體傳遞參數

Angularjs中，$http以post在消息體中傳遞參數，需要做以下修改，以確保消息體傳遞參數的正確性。

 1 var httpPost = function ($httpProvider) {
 2     /*******************************************
 3     說明：$http的post提交時，糾正消息體
 4             參考：http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/

 6     // Use x-www-form-urlencoded Content-Type
 7     $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8';
 8     /*
 9      * The workhorse; converts an object to x-www-form-urlencoded serialization.
10      * @param {Object} obj
11      * @return {String}
12      */
13     var param = function (obj) {
14         var query = '', name, value, fullSubName, subName, subValue, innerObj, i;
15 
16         for (name in obj) {
17             value = obj[name];
18 
19             if (value instanceof Array) {
20                 for (i = 0; i < value.length; ++i) {
21                     subValue = value[i];
22                     fullSubName = name + '[' + i + ']';
23                     innerObj = {};
24                     innerObj[fullSubName] = subValue;
25                     query += param(innerObj) + '&';
26                 }
27             } else if (value instanceof Object) {
28                 for (subName in value) {
29                     subValue = value[subName];
30                     fullSubName = name + '[' + subName + ']';
31                     innerObj = {};
32                     innerObj[fullSubName] = subValue;
33                     query += param(innerObj) + '&';
34                 }
35             } else if (value !== undefined && value !== null)
36                 query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
37         }
38 
39         return query.length ? query.substr(0, query.length - 1) : query;
40     };
41 
42     // Override $http service's default transformRequest
43     $httpProvider.defaults.transformRequest = [
44         function (data) {
45             return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
46         }
47     ];
48 };
49 
50 var ngApp = angular.module('wtApp', ['ngCookies'], httpPost);

二、調用$http post

1 $http({
2     method: 'POST',
3     url: 'GetData.ashx',
4     params: { id: '1002' },//params作為url的參數
5     data: { keyName: 'qubernet' }//作為消息體參數
6 }, function (data) {
7 
8 });
