405方法不允许Web API 2

Question

我已经阅读了几乎所有与此相关的文章，包括SO和其他网站。我已经更改了Web.config文件，以满足答案，因为它们都似乎指向删除WebDAV模块和处理程序。

然而，我仍然遇到错误：

405 Method Not Allowed

所请求的资源不支持“PUT”http方法。

注意：这原本只是一个MVC 4项目。我添加了一些工件来支持Web API。看起来我可能漏掉了一些东西。

注意：从Angular发出的GET调用正常工作。

Web API路由配置：

configuration.Routes.MapHttpRoute(
    name: "Default API",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { action = "Get", id = RouteParameter.Optional },
    constraints: new { id = @"[\da-z-]{36}" });

configuration.Routes.MapHttpRoute(
    name: "Default API with Action",
    routeTemplate: "api/{controller}/{action}",
    defaults: new { action = "Get" });

var formatter = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
formatter.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver();

Web.config

<modules runAllManagedModulesForAllRequests="true">
  <remove name="WebDAVModule" />
</modules>
<handlers accessPolicy="Read, Execute, Script">
  <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>

PUT API入口

public async Task<IHttpActionResult> Put([FromBody] EditUserViewModel viewModel)

客户端

vm.model.$update(function () {
    $state.go(userStates.app);
});

它是不是掉入了第二个路由配置中？如果是，我应该如何验证.NET正在尝试使用哪个路由配置？

可能是[ASP.NET Web API - PUT＆DELETE动词不允许 - IIS 8]的重复问题（https://dev59.com/rGgv5IYBdhLWcg3wBMOg） - BentOnCoding

我会从头开始创建一个Web.API应用程序，重新制造问题并查看是否可以复现。看起来您已经正确地进行了webDAV配置修改。正如您所说，很难确定将其从mvc应用程序转换是否导致了一些未见的管道问题。 - BentOnCoding

也许我在这里漏掉了什么，但是那些路由都会匹配，这意味着第一个路由将被触发？第一个匹配的路由只支持GET请求，这是可能的吗？ - Brendan Green

@BrendanGreen 我也在想同样的问题，但似乎并非如此。我没有收到与多个匹配相关的错误。我在添加新内容后得到了那个错误，而且该错误非常明确。 - Mike Perrenoud

Answer 1

最终，问题似乎是我试图复杂化路由表。最终我将其回滚成以下内容：

configuration.MapHttpAttributeRoutes();

configuration.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional });

请注意，我还添加了configuration.MapHttpAttributeRoutes();。通过这两个改变，一切都工作得很好，信不信由你。 Web.config 如下所示：

<handlers>
  <remove name="ExtensionlessUrl-Integrated-4.0"/>
  <add name="ExtensionlessUrl-Integrated-4.0"
       path="*."
       verb="*"
       type="System.Web.Handlers.TransferRequestHandler"
       preCondition="integratedMode,runtimeVersionv4.0"
       responseBufferLimit="0" />
</handlers>

我也曾经遇到过这个问题，发现需要做更多的工作。你可以试试以下方法：
