c#之ASP.NET Web API 默认不允许 HTTP PUT 和 DELETE_编程设计

我无法遵循 Microsoft 提供的本教程，因为 DELETE 和 PUT 在 ASP.NET Web API 的最新脚手架上默认被阻止:

http://www.asp.net/web-api/overview/older-versions/creating-a-web-api-that-supports-crud-operations

当我尝试执行 PUT 或 DELETE 时，我最终得到来自服务器的响应:

HTTP/1.1 405 Method Not Allowed 
Cache-Control: no-cache 
Pragma: no-cache 
Allow: GET,POST 
Content-Type: application/json; charset=utf-8

{"Message":"The requested resource does not support http method 'DELETE'."}

从这个错误中我可以得出的唯一结论是我的 Web 应用程序在 Debug模式下根本不允许 PUT 和 DELETE，我不知道从这里该怎么做。

这个问题目前只在 Debug模式下发生，我还没有在生产 IIS 机器上正式部署这个构建。可以做什么来允许 PUT 和 DELETE？

这是我的 web.config 文件的样子:

请您参考如下方法:

这是几天前对我的修复。

Web 分布式创作和版本控制 (WebDAV) 导致我的 Web API 不允许放置请求和删除请求。无论是否使用 Debug模式，每次发出请求时，我都会收到 405 Method Not Allowed。

将此添加到您的 Web.Config

<modules> 
  <remove name="WebDAVModule" /> 
</modules> 
 
<handlers> 
  <remove name="ExtensionlessUrlHandler-Integrated-4.0" /> 
  <remove name="OPTIONSVerbHandler" /> 
  <remove name="TRACEVerbHandler" /> 
  <remove name="WebDAV" /> 
</handlers>

然后按照以下步骤操作:

在您的 IIS 管理器中，点击您的网站，然后打开 WebDAV 创作。
在 IIS 管理器的右侧，您会看到 WebDAV 设置.. 打开它。
在请求过滤行为下将允许动词过滤设置为假
