Angularjs中$http以post請求通過消息體傳遞參數的實現方法

本文實例講述了Angularjs中$http以post請求通過消息體傳遞參數的方法。分享給大家供大家參考，具體如下：

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。

一、在聲明應用的時候進行設置：

 var httpPost = function($httpProvider) { /******************************************* 說明：$http的post提交時，糾正消息體********************************************/ // Use x-www-form-urlencoded Content-Type $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8'; /* * The workhorse; converts an object to x-www-form-urlencoded serialization. * @param {Object} obj * @return {String} */ var param = function(obj) { var query = '', name, value, fullSubName, subName, subValue, innerObj, i; for (name in obj) { value = obj[name]; if (value instanceof Array) { for (i = 0; i < value.length; ++i) { subValue = value[i]; fullSubName = name + '[' + i + ']'; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + '&'; } } else if (value instanceof Object) { for (subName in value) { subValue = value[subName]; fullSubName = name + '[' + subName + ']'; innerObj = {}; innerObj[fullSubName] = subValue; query += param(innerObj) + '&'; } } else if (value !== undefined && value !== null) query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&'; } return query.length ? query.substr(0, query.length - 1) : query; }; // Override $http service's default transformRequest $httpProvider.defaults.transformRequest = [ function(data) { return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data; } ];};var ngApp = angular.module('wtApp', ['ngCookies'], httpPost);

二、調用$http post

 $http({ method: 'POST', url: 'GetData.ashx', params: { id: '1002' },//params作為url的參數data: { keyName: 'qubernet' }//作為消息體參數}, function (data) {});

希望本文所述對大家AngularJS程序設計有所幫助。
