Question

我创建了WCF RESTful服务，它使用简单的数据库，只是尝试处理put，get，post和delete项目。现在发布，put和get工作正常。但删除是行不通的。一些论坛告诉我需要禁用WebDAV模块。我做到了，然后我得到PUT工作。但我不能让DELETE工作。每当我通过我的服务调用DELETE动词时，我都会收到以下错误：

远程服务器返回了意外响应：（405）Method Not Allowed。

任何人都可以帮我吗？

Answer 1

我还没有找到一个全面的答案，PUT和DELETE被覆盖，并在其他任何地方为宁静的WCF服务返回405s，所以我将在这里发布。

只需通过角色管理器（在服务器上）或通过添加/删除窗口功能从计算机上卸载WebDAV，即可轻松解决此问题。如果这是一种易受影响的方法，你现在就可以停止阅读了。

这里通常建议的修复方法是从您的站点中删除WebDAV模块，在Web.config中添加如下内容：

  <system.webServer>
        <modules>
            <remove name="WebDAVModule" />
        </modules>
  </system.webServer>

这里的问题是，现在你的WCF应用程序根本无法知道如何处理PUT和DELETE。因此，为了解决这个问题，一些解决方案建议进行以下修改：

<modules runAllManagedModulesForAllRequests="true">
 <system.webServer>
       <modules>
           <remove name="WebDAVModule" />
       </modules>
 </system.webServer>

这对大多数人来说可能是令人满意的，但我不喜欢在没有必要时让我们的服务无用地为每次通话加载所有内容的想法。所以我通过手动将无扩展名URL处理程序映射到所有HTTP动词（可能可以简化为必要的动词）来改进方法（

）

  <system.webServer>
        <modules>
            <remove name="WebDAVModule" />
        </modules>
        <handlers>
            <remove name="WebDAV" />
            <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
            <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />
        </handlers>
  </system.webServer>

我只在R2 64和7 64上测试了这个，所以ymmv。但希望这会有所帮助。

StackOverflow似乎也有类似的问题：

WCF Service 405 Method Not Allowed Exception

WCF The request failed with HTTP status 405: Method Not Allowed

WCF Service Returning "Method Not Allowed"

希望其中一人有所帮助。

Answer 3

我在客户端使用WebChannelFactory方法来使用REST服务。我使用常规的“添加服务引用”方法创建了服务引用。这不会添加[WebGet(UriTemplate = "/")]。

我在客户端代理类的所有操作中添加了这些，就像服务合同一样，它开始工作。
