WebApi系列~基于RESTful标准的Web Api 转载 https://www.cnblogs.com/lori/p/3555737.html

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

注意上面公开的API接口都是在XMLHttpRequest情况下调用的，当然你可以使用jquery的ajax组件来完成这个请求调用，它的代码更加面向对象，下面举例说明一下

这是页面的HTML代码部分，实现最基本的CRUD操作

    function add() {

        $.ajax({
            url    : "/api/Test/",
            type   : "POST",
            data   :{"UserID":4,"UserName":"test","UserEmail":"[e-mail]"},
            success: function (data) { alert(JSON.stringify(data)); }

        });

    }

    //更新
    function update(id) {
        $.ajax({
            url    : "/api/Test?id="+id,
            type   : "Put",
            data   :{"UserID":1,"UserName":"moditest","UserEmail":"[e-mail]"},
            success: function (data) { alert(JSON.stringify(data)); }
        });

    }
    function deletes(id) {
        $.ajax({
            url    : "/api/Test/1",
            type   : "DELETE",
            success: function (data) { alert(data);}
        });

    }
