首先呢，同志们，我们需要  引用两个插件，

之后创建两个项目。

之后创建API服务端。和  Ef链接数据库  

之后写好API

如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Cors;
using WebApi_ZK3_.Models;

namespace WebApi_ZK3_.Controllers
{
[EnableCors("*", "*", "*")]
public class UserInfoController : ApiController
{
// GET: api/UserInfo
ZK3Entities db = new ZK3Entities();
/// <summary>
/// 显示
/// </summary>
/// <returns></returns>
public IEnumerable<UserInfo> Get()
{
return db.UserInfoes.ToList();
}

// GET: api/UserInfo/5
/// <summary>
/// 单条数据查询
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public IEnumerable<UserInfo> Get(int id)
{
var us = db.UserInfoes.Where(T => T.I_ID == id);
return us;
}
[HttpPost]
// POST: api/UserInfo
/// <summary>
/// 添加
/// </summary>
/// <param name="u"></param>
public void Post([FromBody]UserInfo u)
{
db.UserInfoes.Add(u);
db.SaveChanges();

}
// PUT: api/UserInfo/5
/// <summary>
/// 修改
/// </summary>
/// <param name="id"></param>
/// <param name="u"></param>
public void Put(int id, [FromBody]UserInfo u)
{
var us = db.UserInfoes.Where(T => T.I_ID == id).FirstOrDefault();
if (us != null)
{
us.I_Num = u.I_Num;
us.I_Type = u.I_Type;
us.I_Money = u.I_Money;
us.I_Name = u.I_Name;
us.I_Datetime = u.I_Datetime;
db.SaveChanges();
}

}

// DELETE: api/UserInfo/5
/// <summary>
/// 删除
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public HttpResponseMessage Delete(int id)
{
var us = db.UserInfoes.Where(T => T.I_ID == id).FirstOrDefault();
if (us != null)
{
db.UserInfoes.Remove(us);
db.SaveChanges();
return new HttpResponseMessage() { StatusCode = HttpStatusCode.OK };
}
else
{
return new HttpResponseMessage() { StatusCode=HttpStatusCode.NoContent};
}
}
}
}

上面是API   

到这一步  API已经完成  

请打开MVC项目

创建控制器，编写以下代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Newtonsoft.Json;
using System.Net.Http;
using System.Net.Http.Headers;
using MVC_ZK3_.Models;
using Webdiyer.WebControls.Mvc;//分页

namespace MVC_ZK3_.Controllers
{
public class UserInfoController : Controller
{
// GET: UserInfo
/// <summary>
/// 显示+模糊+分页
/// </summary>
/// <param name="name"></param>
/// <returns></returns>
public ActionResult Index(string name = "" , int pageIndex = 1)
{

Uri url = new Uri("http://localhost:53076/");
HttpClient client = new HttpClient();
client.BaseAddress = url;
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage mess = client.GetAsync("/api/UserInfo").Result;
if (mess.IsSuccessStatusCode)
{
var list = mess.Content.ReadAsStringAsync().Result;
List<InfoM> m = JsonConvert.DeserializeObject<List<InfoM>>(list);

if (name == "")
{
return View(m /*.ToPagedList(pageIndex, 2)*/);
}
else
{
List<InfoM> fm = (m.Where(T => T.I_Name.Contains(name)).ToList());
return View(fm /*.ToPagedList(pageIndex,2)*/);
}
}
return View("");
}
/// <summary>
/// 删除
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public ActionResult Delete(int id)
{
Uri url = new Uri("http://localhost:53076/");
HttpClient client = new HttpClient();
client.BaseAddress = url;
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//返回
HttpResponseMessage mess = client.DeleteAsync("api/UserInfo/" + id).Result;
//判断
if (mess.IsSuccessStatusCode)
{
return Content("<script>alert(‘删除成功‘);location.href=‘/UserInfo/Index‘</script>");
}
return Content("<script>alert(‘删除失败‘)</script>");

}
/// <summary>
/// 添加
/// </summary>
/// <returns></returns>
public ActionResult Post()
{
return View();
}
[HttpPost]
public ActionResult Post(InfoM m)
{
Uri url = new Uri("http://localhost:53076/");
HttpClient client = new HttpClient();
client.BaseAddress = url;
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//定义对象
HttpContent cen = new StringContent("{‘I_Num‘:‘" + m.I_Num + "‘,‘I_Type‘:‘" + m.I_Type + "‘,‘I_Money‘:‘" + m.I_Money + "‘,‘I_Name‘:‘" + m.I_Name + "‘,‘I_Datetime‘:‘" + m.I_Datetime + "‘}");
cen.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json");
HttpResponseMessage mess = client.PostAsync("/api/UserInfo",cen).Result;
if (mess.IsSuccessStatusCode)
{
return Content("<script>alert(‘添加成功‘);location.href=‘/UserInfo/Index‘</script>");;
}
client.Dispose();
return Content("<script>alert(‘添加失败‘)</script>");
}
/// <summary>
/// 修改
/// </summary>
/// <returns></returns>
public ActionResult Put(int id)
{
Uri url = new Uri("http://localhost:53076/");
HttpClient client = new HttpClient();
client.BaseAddress = url;
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage mess = client.GetAsync("/api/UserInfo/" + id).Result;
if (mess.IsSuccessStatusCode)
{
var list = mess.Content.ReadAsStringAsync().Result;
var m = JsonConvert.DeserializeObject<List<InfoM>>(list);

InfoM i = new InfoM();
i.I_ID = m[0].I_ID;
i.I_Money = m[0].I_Money;
i.I_Name = m[0].I_Name;
i.I_Num = m[0].I_Num;
i.I_Type = m[0].I_Type;
i.I_Datetime = m[0].I_Datetime;
return View(i);
}

return View("");
}
[HttpPost]
public ActionResult Put(InfoM m)
{
Uri url = new Uri("http://localhost:53076/");
HttpClient client = new HttpClient();
client.BaseAddress = url;
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//定义对象
HttpContent cen = new StringContent("{‘I_ID‘:‘" + m.I_ID + "‘,‘I_Num‘:‘" + m.I_Num + "‘,‘I_Type‘:‘" + m.I_Type + "‘,‘I_Money‘:‘" + m.I_Money + "‘,‘I_Name‘:‘" + m.I_Name + "‘,‘I_Datetime‘:‘" + m.I_Datetime + "‘}");
cen.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json");
HttpResponseMessage mess = client.PutAsync("/api/UserInfo/" + m.I_ID, cen).Result;
if (mess.IsSuccessStatusCode)
{
return Content("<script>alert(‘修改成功‘);location.href=‘/UserInfo/Index‘</script>");
}
client.Dispose();
return Content("<script>alert(‘修改失败‘);location.href=‘/UserInfo/Index‘</script>");
}

}
}

切记哦，MVC里面需要写个类  进行数据交互

显示代码如下

@{
Layout = null;
}
@using Webdiyer.WebControls.Mvc;
@model PagedList<MVC_ZK3_.Models.InfoM>
<!DOCTYPE html>

<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<style>
table {
border:1px solid #ff0000;
width:900px;
text-align:center;
}
table tr {
border:1px solid #ff0000;
}
table tr td {
border:1px solid #ff0000;
}
</style>
</head>
<body>
<div>

<a href="Post">添加</a>&nbsp;
<input id="Text1" type="text" placeholder="请输入缴费人姓名" />
<input id="Button1" type="button" value="查询" onclick="cha()" />
<table cellpadding="0" cellspacing="0">
<thead>
<tr>
<td>编号</td>
<td>门牌号</td>
<td>缴费类型</td>
<td>缴费金额</td>
<td>缴费人</td>
<td>缴费时间</td>
<td>操作</td>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>@item.I_ID</td>
<td>@item.I_Num </td>
<td>@item.I_Type </td>
<td>@item.I_Money </td>
<td>@item.I_Name </td>
<td>@item.I_Datetime</td>
<td>
<a href="#" onclick="del(@item.I_ID)">删除</a>
<a href="#" onclick="updt(@item.I_ID)">修改</a>
</td>
</tr>
}
</tbody>
</table>
//分页
@Html.Pager(Model,new PagerOptions() { PageIndexParameterName= "pageIndex" })
</div>
<script>
//删除
function del(id)
{
location.href = "/UserInfo/Delete?id="+id;
}
//修改
function updt(id)
{
location.href="/UserInfo/Put?id="+id;

}
//查询
function cha()
{
var name = $("#Text1").val();
location.href = "/UserInfo/Index?name="+name;
}
</script>
</body>
</html>
