很多时候我们需要用ajax提交post数据，angularjs与jq类似，也有封装好的post。

但是jQuery的post明显比angularjs的要简单一些，人性化一些。

两者看起来没什么区别，用angularjs的$http提交的数据，在php服务器端却无法通过$_REQUEST/$_POST获取到。

这是因为两者的post对header的处理有所不同……jQuery会把作为JSON对象的myData序列化，而Angular不会。

修改Angular的$httpProvider的默认处理（最完美的解决方案）

angular.module('MyModule', [], <span style="color: #0000ff;">function</span><span style="color: #000000;">($httpProvider) {
  </span><span style="color: #008000;">//</span><span style="color: #008000;"> Use x-www-form-urlencoded Content-Type</span>
  $httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded;charset=utf-8'<span style="color: #000000;">;
 
  </span><span style="color: #008000;">/*</span><span style="color: #008000;">*
   * The workhorse; converts an object to x-www-form-urlencoded serialization.
