当我尝试调用 Delete Web API 时，我得到：

NetworkError: 404 Not Found - /api/tradespendentryip/5

我的 API 控制器如下所示：

public class TradeSpendEntryIPController : ApiController
{
    // DELETE api/tradespendentryip/5
    public void Delete(int id)
    {
        string x = id.ToString(); //I put a breakpoint here which never gets hit
    }
}

我用这个 jQuery 片段调用它，硬编码创建 Web API 时生成的提示 URL：

$.ajax({
                type: "DELETE",
                url: "/api/tradespendentryip/5"
                }).done(function( msg ) {
                    alert( 'Record deleted.');
                }).fail(function(jqXHR, textStatus){
                    alert('Unable to delete this record at this time.');
                });

检查 Firebug 中的网络选项卡，我总是得到“NetworkError：404 Not Found - /api/tradespendentryip/5”

根据网络上的一些研究，我尝试调整我的 web.config 以便 WebDAV 不会干扰：

<modules runAllManagedModulesForAllRequests="true">
  <remove name="WebDAVModule" />
  <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
  <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
</modules>
<handlers>
  <remove name="WebDAV" />
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
  <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
  <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
  <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

有没有人知道可能是什么问题？我的日志中也生成了这个事件，表明“路径'DELETE'被禁止。 ”：

你在什么网络服务器上开发？我相信旧的卡西尼开发服务器除了get和post之外对http动词没有很好的支持。如果您使用的是 cassini，请尝试使用 IIS Express。
