1       大概思路

l  创建WebAPI

l  创建CrossMainController并编写

l  Nuget安装microsoft.aspnet.webapi.cors

l  跨域设置路由

l  编写Jquery EasyUI界面

l  运行效果

2       创建WebAPI

创建WebAPI,新建->项目->ASP.NET Web应用程序->Web API

3       创建CrossMainController并编写

编写如下:

using CrossdomainWebApi.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http; namespace CrossdomainWebApi.Controllers
{
[RoutePrefix("api/CrossMain")]
public class CrossMainController : ApiController
{
[Route("GetUserInfo")]
[HttpPost]
public HttpResponseMessage GetUserInfo([FromBody]formUserInfo obj)
{
//[FromBody]int page, [FromBody]int rows, [FromBody]string email
List<UserInfoViewModel> listStudent = new List<UserInfoViewModel>();
for (int i = ; i < ; i++)
{
UserInfoViewModel student = new Models.UserInfoViewModel();
Random ran = new Random();
student.Email = i.ToString() + ran.Next(, ).ToString() + "System@qq.com";
student.HasRegistered = true;
student.LoginProvider = "Yes";
listStudent.Add(student);
} int page = obj.page;
int rows = obj.rows;
List<UserInfoViewModel> ts = new List<UserInfoViewModel>();
for (int i = (page - ) * rows; i < (page * rows>listStudent.Count? listStudent.Count:page * rows) ; i++)
{
ts.Add(listStudent[i]);
} string json= Newtonsoft.Json.JsonConvert.SerializeObject(new { rows = ts, total = listStudent.Count, success = true });
return new HttpResponseMessage { Content = new StringContent(json, System.Text.Encoding.UTF8, "text/plain") };
}
} /// <summary>
/// form提交数据
/// </summary>
public class formUserInfo
{
public int page { get; set; }
public int rows { get; set; }
public string email { get; set; }
}
}

5       跨域设置路由

设置项目 crossdomainwebapi\crossdomainwebapi\app_start\webapiconfig.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web.Http;
using Microsoft.Owin.Security.OAuth;
using Newtonsoft.Json.Serialization;
//跨域引用
using System.Web.Http.Cors; namespace CrossdomainWebApi
{
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Configure Web API to use only bearer token authentication.
//config.SuppressDefaultHostAuthentication();
//config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType)); //跨域配置
config.EnableCors(new EnableCorsAttribute("*", "*", "*"));
// Web API routes
config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}

6       编写Jquery EasyUI界面

前台界面代码如下:

<!DOCTYPE HTML>
<html>
<head>
<title>Ems SA</title>
<link rel="stylesheet" type="text/css" href="JqueryEasyui/themes/bootstrap/easyui.css" />
<link rel="stylesheet" type="text/css" href="JqueryEasyui/themes/icon.css" />
<link rel="stylesheet" type="text/css" href="JqueryEasyui/demo/demo.css" />
<script type="text/javascript" src="JqueryEasyui/jquery.min.js"></script>
<script type="text/javascript" src="JqueryEasyui/jquery.easyui.min.js"></script>
<script type="text/javascript">
function doSearch() { }
</script>
</head>
<body>
<div>
<table id="dg" class="easyui-datagrid" style="width: 100%; height: auto; min-height: 400px"
data-options="
iconCls: 'icon-edit',
singleSelect: true,
url: 'http://localhost:26735/Api/CrossMain/GetUserInfo',
method: 'post',
pagination:true,
pageSize:15,
pageList: [5, 10, 15],
queryParams: {'email': ‘’}
">
<thead>
<tr>
<th data-options="field:'ck',checkbox:true">
</th>
<th data-options="field:'Email',width:'20%'">
Email
</th>
<th data-options="field:'HasRegistered'">
HasRegistered
</th>
<th data-options="field:'HasRegistered'">
HasRegistered
</th>
</tr>
</thead>
</table>
</div>
</body>
</html>

7       运行效果

启动WebAPI,并刷新Jquery EasyUI界面,可见如下图:

8       总结

WebAPI提供广泛的对外开放,可以起到整合性的作用,例如:跟Oracle ERP、SAP的SCM、MM、PP以及SD领域。WebAPI形成一个Web标准,对于一些微服务,也起到关键性的作用。跨域还能不受限制让更多人访问,当然,也降低了安全性。
