Asp.net web api ASP.NET Web API-删除时为404

我试图在Web API控制器上实现

Delete

方法。但是，我总是得到一个

404-未找到

。在这一点上，我已经得到了GET、POST和PUT方法，这些方法工作得很好。我已经阅读了其他一些关于同一问题的SO帖子，只是没有一篇有效

控制器动作 AJAX请求 Web.Config 这是我的

web.config

文件。除了模块部分，所有内容都与我创建项目时相同：

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <!--<modules runAllManagedModulesForAllRequests="true"></modules>-->
    <modules>
      <remove name="UrlRoutingModule-4.0" />
      <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
    </modules>
    <handlers>
      <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>
</system.webServer>

以下是回应：

这是一个教我自己的开源软件。我查了最新的资料，以防有人想看到完整的资料来源

public virtual HttpResponseMessage Delete(string customerId)

---

参数是一个简单类型，它是从URI绑定的，而不是从请求体绑定的。在查询字符串中传递客户ID，如下-

http://localhost:63654/TestMvcApplication/api/Customer?customerId=123

或将签名更改为

公共虚拟HttpResponseMessage Delete（字符串id）

并使用URI

http://localhost:63654/TestMvcApplication/api/Customer/123

此外，HTTP规范指出，与GET相同，带有DELETE请求的有效负载没有语义，因此您永远不应该使用正文发送带有DELETE的参数。我从来没有想到{id}意味着参数名必须是

id

@DarrelMiller谢谢你的提示@Darrel Miller我几乎想过建议OP使用复杂类型，但不确定这是否正确。你的评论真的很有帮助。谢谢
