c# - 405 方法不允许 Web API 2

Question

我已经浏览了几乎所有我能找到的关于 SO 和更多的文章。我对 Web.config 进行了更改以满足答案，因为它们似乎都指向删除 WebDAV 模块和处理程序。

但是，我仍然遇到错误:

405 Method Not Allowed

The requested resource does not support http method 'PUT'.

注意:这最初只是一个 MVC 4 项目。我添加了工件来支持 Web API。似乎我可能错过了一些东西。

注意 GET 调用在 Angular 中运行良好。

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);
});

有没有可能是属于第二种路由配置？如果是这样，我如何验证 .NET 尝试使用的路由配置？

最后看来是我试图使路由表复杂化。我最终将它回滚到这个:

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();。

信不信由你，在这两项更改之后，一切都运行良好。 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>
