Question

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代码段调用它，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＆＃34; NetworkError：404 Not Found - / api / tradespendentryip / 5＆＃34;

通过网络上的一些研究，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>

是否有其他人知道问题可能是什么？我也在我的日志中生成了此事件，表示＆＃34; 路径＆＃39;删除＆＃39;被禁止。＆＃34;：

您正在开发哪种Web服务器？我相信除了get和post之外，旧的cassini开发服务器对http动词没有很大的支持。如果您使用的是cassini，请尝试使用IIS Express。
