ASP.NET MVC WebAPI Put和Delete请求出现405(Method not allowed)错误

解决办法：

在站点根目录下的web.config设置如下(主要参考添加项)：

<system.webServer>
<modules>
<remove name="FormsAuthentication" />
<remove name="ApplicationInsightsWebTracking" />
<remove name="WebDAVModule" /> <!--添加项 -->
<add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
</modules>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<remove name="WebDAV" /> <!--添加项 -->
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>

 

(End)
