删除webapi的删除操作方法没有被触发。 [英] Delete action method of webapi is not getting triggered.
问题描述
我的MVC项目中有一个web api控制器，如下所示
I have a web api controller in my MVC project as follows
public class EmployeeController : ApiController
{
static readonly IEmployeeRepository repository = new EmployeeRepository();
// GET api/<controller>
[HttpGet]
public object Get()
{
var queryString = HttpContext.Current.Request.QueryString;
var data = repository.GetAll().ToList();
return new { Items = data, Count = data.Count() };
}
public Employee GetEmployee(int id)
{
Employee emp = repository.Get(id);
if (emp == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
return emp;
}
// POST api/<controller>
public HttpResponseMessage PostEmployee(Employee emp)
{
emp = repository.Add(emp);
var response = Request.CreateResponse<Employee>(HttpStatusCode.Created, emp);
string uri = Url.Link("Employee", new { id = emp.EmployeeID });
response.Headers.Location = new Uri(uri);
return response;
}
[HttpPut]
// PUT api/<controller>
public void PutEmployee(Employee emp)
{
if (!repository.Update(emp))
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
}
[HttpDelete]
public void Delete(int id)
{
Employee emp = repository.Get(id);
if (emp == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
repository.Remove(id);
}
}
对我来说，添加（Put），检索（获取）和更新（发布）方法被触发
但是，删除方法没有被触发
我的删除方法的URL是：
http：// localhost：63187 / api / Employee / 2
和我的Webapicongif。 cs
For me, Add(Put), Retrieve (get) and Update (Post) method getting triggered
But, Delete method is not getting triggered
And my URL of Delete Method is :
http://localhost:63187/api/Employee/2
and my Webapicongif.cs
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "Employee",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
//config.EnableQuerySupport();
}
和global.cs文件如下
and the global.cs file as follows
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
GlobalConfiguration.Configure(WebApiConfig.Register);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
我的尝试：
当我执行删除操作时，
i收到错误报告
消息：找不到与请求URI匹配的HTTP资源'http：// localhost：63187 / api / Employee / 2'。
MessageDetail
：
控制器'员工'上没有找到与名称'2'匹配的操作。

Where i am committing the mistake.
推荐答案
最后我发现了问题，我在Global.cs和WebApiConfig中犯了错误
已更新的Global.cs已提交
At last i found the issue, i have done the mistake in Global.cs and WebApiConfig
Updated Global.cs filed
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
//GlobalConfiguration.Configure(WebApiConfig.Register);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
// WebApiConfig.Register(GlobalConfiguration.Configuration);
}
和WebApiConfig
and WebApiConfig
public static void Register(HttpConfiguration config)
{
//config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "Employee",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
//config.EnableQuerySupport();
}
现在，已触发删除操作更新。
Now, the Delete action updated triggered.
