Question

我必须错过一些非常容易的事情。我正在使用Xamarin Studio编写NancyFx应用程序。我想在我的模块中使用PUT和DELETE HTTP方法，但是当我发出PUT或DELETE请求时，我回到405 Method Not Allowed并在HTTP响应头中看到Allow: GET, POST。

我的应用程序在OSX上的Xamarin Studio中的xsp4下运行。我在此问题上遇到的大多数解决方案仅在IIS下运行时才有意义。

如何在xsp4 / Mono / Nancy中启用PUT和DELETE？我不相信南希是个问题。我很确定这仅限于Mono上的xsp4服务器。我在web.config文件中遗漏了什么（在下面发布）？

我的Nancy模块中的DELETE处理程序如下所示：

Delete["/api/family/{id}"] = _ => 
{
    int rows = 0;

    using (IDbConnection con = dbFactory.Open())
        rows = con.Execute("DELETE FROM Family WHERE Id=?", new { Id = _.id });

    return Response.AsJson(rows, HttpStatusCode.OK);
};

我的web.config文件非常简单。它几乎只能在所有路径和动词上启用Nancy，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <httpHandlers>
      <add verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />
    </httpHandlers>
    <compilation>
      <assemblies>
        <add assembly="Mono.Data.Sqlite, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756" />
        <add assembly="System.ComponentModel.DataAnnotations, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
        <add assembly="System.Runtime.Serialization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
        <add assembly="Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      </assemblies>
    </compilation>
  </system.web>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <httpErrors existingResponse="PassThrough" />
    <handlers>
      <add name="Nancy" verb="*" type="Nancy.Hosting.Aspnet.NancyHttpRequestHandler" path="*" />
    </handlers>
  </system.webServer>
</configuration>

以下是来自curl的HTTP会话：

> PUT /api/family HTTP/1.1
> User-Agent: curl/7.30.0
> Host: localhost:8080
> Accept: */*
> Content-Type: application/json

有点晚了，但这可能是一个问题，需要在Nancy bootstrapper中启用CORS上的DELETE方法：

    protected override void RequestStartup(TinyIoCContainer container, IPipelines pipelines, NancyContext context)
    {
        base.RequestStartup(container, pipelines, context);

        //CORS Enable
        pipelines.AfterRequest.AddItemToEndOfPipeline((ctx) =>
        {
            ctx.Response.WithHeader("Access-Control-Allow-Origin", "*")
                            .WithHeader("Access-Control-Allow-Methods", "POST,GET,DELETE")
                            .WithHeader("Access-Control-Allow-Headers", "Accept, Origin, Content-type");

        });

如何在Mono上的xsp4中启用运行Nancy的PUT和DELETE HTTP方法？
