[Java教程]Angularjs中$http以post请求通过消息体传递参数


Angularjs中,$http以post在消息体中传递参数,需要做以下修改,以确保消息体传递参数的正确性。

 
一、在声明应用的时候进行设置:
 1 var httpPost = function ($httpProvider) { 2   /******************************************* 3   说明:$http的post提交时,纠正消息体 4       参考:http://victorblog.com/2012/12/20/make-angularjs-http-service-behave-like-jquery-ajax/ 5   ********************************************/ 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} obj11    * @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 transformRequest43   $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、调用$http post

1 $http({2   method: 'POST',3   url: 'GetData.ashx',4   params: { id: '1002' },//params作为url的参数5   data: { keyName: 'qubernet' }//作为消息体参数6 }, function (data) {7 8 });
