405不允许的方法Web API 2

Question

我已经阅读了我能找到的关于SO等的几乎每一篇文章。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。

然而，我仍然得到错误：

405不允许的方法

请求的资源不支持http方法"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。看来我可能错过了什么。

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.NETFrameworkv4.0.30319aspnet_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.NETFramework64v4.0.30319aspnet_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条目

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

客户端

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

它有可能落入第二种路线配置吗？如果是，我如何验证.NET尝试使用的路由配置？

Answer 1

最后，我似乎试图使路由表复杂化。我最后把它回滚到这个：

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

请注意，我也添加了configuration.MapHttpAttributeRoutes();。

信不信由你，经过这两次改变后，一切都很顺利。Web.config看起来像这样：

<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>

我也在努力解决这个问题，发现我必须做得更多。试试看：
