最近在开发asp.net core时，遇到RequestBody和RequestForm数据提交方式，整理了一下，把结果记录下来。
对于RequestForm一般是接收表单的信息，而RequestBody通常是来接收较为复杂的数据（集合或杂杂对象）在asp.net中很容易区分接收，在action用[FromBody]和[FromForm]来标识就可以，对于客户端来说，区别就要大一些，这里记录两种方式，RestSharp和JQuery的ajax请求两种方式。

[HttpPost(
"additem"
)]
public
IActionResult AddItem([FromBody]Item item)
{
return
new
JsonResult(
new
{ Result = 0, Message =
"添加成功"
,Content=item.ToString() },
new
Newtonsoft.Json.JsonSerializerSettings ());
}
[HttpPost(

RestSharp方式
在项目中，用Nuget安装RestSharp类库，我用的是v105.2.3。
用RestSharp提交RequestBody和RequestForm相对简单，代码如下：

using
System;
using
RestSharp;
namespace
RestSharpTest
{
class
Program {
static
void
Main(
string
[] args)
{
while
(
true
)
{
var
client =
new
RestClient(
"http://localhost:5000"
);
var
request =
new
RestRequest(
"additem"
, Method.POST);
request.RequestFormat = DataFormat.Json;
Console.WriteLine(
"1、RequestBody 2、RequestForm"
);
switch
(Console.ReadLine())
{
case
"1"
:
request.AddJsonBody(
new
{ ID = 111, Name =
"张三"
, Birthday = DateTime.Now });
break
;
case
"2"
:
request.AddObject(
new
{ ID = 111, Name =
"张三"
, Birthday = DateTime.Now });
break
;
}
var
response = client.Execute(request);
Console.WriteLine(response.Content);
}
}
}
}

JQuery中用ajax请求
如果用jquery访问别的web，设置跨域访问（关于跨域访问，查看http://www.cnblogs.com/xishuai/p/aspnet-core-cors.html）

一般情况下，web api是用[FromBody]，因为一般web api是供app或DeskTop的应用访问，web页面请求用[FromForm]，一般情况下web页面是通过表单向后台提交信息。
