angular post json数据到服务器，跨域访问，多大括号

 angular.module('myApp',[]).config(function($httpProvider) {

            // Override $http service's default transformRequest
            $httpProvider.defaults.transformRequest = [function(data)

感谢，终于找到json数据post到服务器的传输方式，不会再报跨域访问和服务器接收格式的错误

，多个括号的问题烦死我了，（{‘{"params1":"xxxx","params2":"cxxxxxx"}‘,‘‘}）,终于解决了，

说白了就是转成application/x-www-form-urlencoded , 参数之间加上&

或者你post请求的data,定义由 data: {"params1":"xxxx","params2":"cxxxxxx"}  改成params1="xxxx"&params2="xxxx"，

1.以下是我定义，主要用于解决跨域访问，是angularjs CORS提供的标准方式

$httpProvider.defaults.useXDomain = true;

delete $httpProvider.defaults.headers.common[‘X-Requested-With‘];

$httpProvider.defaults.headers.post[‘Content-Type‘] = ‘application/x-www-form-urlencoded;charset=utf-8‘;

$httpProvider.defaults.headers.put[‘Content-Type‘] = ‘application/x-www-form-urlencoded;charset=utf-8‘;

2.

$httpProvider.defaults.transformRequest 这个定义被重写，

帮我们完成了json数据请求转成params1="xxxx"&params2="xxxx"格式
