asp.net core下的RequestBody和RequestForm提交

2017-01-24 15:35 706 查看

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。服务端

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

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）

<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>    <title></title>
<meta charset="utf-8" />    <script src="bower_components/jquery/dist/jquery.min.js"></script></head><body>    <input id="sava1" value="保存RequestForm" type="button"/>    <input id="sava2" value="保存RequestBody" type="button" />    <script>        $("#sava1").click(function () {
$.post("http://localhost:5000/additem", { ID: 112, Name: "李四", Birthday: "2017-01-23" }, function (result) {
alert(result.Message+result.Content);
},"json")
})

$("#sava2").click(function () {
$.ajax({
type: "POST",
url: "http://localhost:5000/additem",
contentType: "application/json",
dataType: "json",
async: true,
data: JSON.stringify({ "ID": 112, "Name": "李四", "Birthday": "2017-01-23 12:12:12" }),
success: function (result) {
alert(result.Message + result.Content);
}
});

})
</script></body></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。
