.NET Web API 2 和 IIS PUT/DELETE 不工作

Question

在对我的 Web API 2 Controller 发出 DELETE 请求时，我得到:

Request URL:http://localhost/phoenix/api/apps/1245 
Request Method:DELETE
Status Code:404 Not Found

DELETE http://localhost/myapp/api/apps/1245 404 (Not Found) 

我的 Controller 看起来像:

    [EnableCors(origins: "http://localhost", headers: "*", methods: "*", SupportsCredentials = true)]
[Route("api/apps")]
public class ApplicationController : ApiController
{
    // DELETE api/apps/5
    public void Delete(string id)
    {
        //apps.Delete(id);
    }
}

我的 IIS 是为 PUT/DELETE 动词设置的:

我的 web.config 有 * 用于动词:

<system.webServer>
  <handlers>
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <remove name="OPTIONSVerbHandler" />
  <remove name="TRACEVerbHandler" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
  </handlers>
</system.webServer>

我错过了什么？

Answer 1

id 参数不在路由模板中。将您的 Controller 级路由更改为 [Route("api/apps/{id?}")] 或从查询字符串中提供 id 值...
