* 微软的web api是在vs2012上的mvc4项目绑定发行的,它提出的web api是完全基于RESTful标准的,
* 完全不同于之前的(同是SOAP协议的)wcf和webService,它是简单,代码可读性强的,上手快的,
* 如果要拿它和web服务相比,我会说,它的接口更标准,更清晰,没有混乱的方法名称,
*
* 有的只有几种标准的请求,如get,post,put,delete等,它们分别对应的几个操作,下面讲一下:
* GET:生到数据列表(默认),或者得到一条实体数据
* POST:添加服务端添加一条记录,记录实体为Form对象
* PUT:添加或修改服务端的一条记录,记录实体的Form对象,记录主键以GET方式进行传输
* DELETE:删除 服务端的一条记录
