====》两种网络服务
1.WebService:基于SOAP风格的网络服务，使用方法进行请求
2.WebAPI ：基于REST风格的网络服务，使用资源进行请求；5个方法：查一个，查所有，增加，修改，删除就是定义一个控制器继承于WebAPIControler类
public class UserInfoController : ApiController { // GET api/userinfo public IEnumerable<UserInfo> Get() { List<UserInfo> lUsers = new List<UserInfo>(); lUsers.Add(new UserInfo() { ID=1, Name="孙宝" }); lUsers.Add(new UserInfo() { ID = 2, Name = "王沙" }); lUsers.Add(new UserInfo() { ID = 3, Name = "王闯" }); return lUsers; } // GET api/userinfo/5 [HttpGet] public string Get(int id) { return "value"; } // POST api/userinfo [HttpPost] public void Post([FromBody]string value) { } // PUT api/userinfo/5 [HttpPut] public void Put(int id, [FromBody]string value) { } // DELETE api/userinfo/5 [HttpDelete] public void Delete(int id) { } }
====》使用 1.jquery 的ajax (缺点，不能跨域)
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script src="Scripts/jquery-1.8.2.min.js"></script> <script type="text/javascript"> $(function () { LoadList(); }); function LoadList() { $.ajax({ type: 'get',//请求方式，可以为get post add delete data: '{}',//发送的参数 url: 'http://localhost:33587/api/UserInfo', //请求的地址 contentType: "application/json;charset=utf-8",//数据格式 dataType: 'json', //数据形式 success: function (list) { var tlist = $("#list"); tlist.empty(); $.each(list, function (index,item) { tlist.append('<tr><td>' + item.ID + '</td><td>' + item.Name + '</td></tr>'); }); } }); } </script> </head> <body> <table border="1"> <tr> <td>编号</td> <td>姓名</td> </tr> <tbody id="list"></tbody> </table> </body> </html>
2.HttpClient
HttpClient client = new HttpClient(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); //执行Get操作 HttpResponseMessage response = client.GetAsync("http://localhost:33587/api/UserInfo").Result; var lUsers= response.Content.ReadAsAsync<List<UserInfo>>().Result; ViewData.Model = lUsers;
请求，由路由规则决定
public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } }
