404响应追加到的WebAPI响应
问题描述：
我设法让两个响应单个Web请求：404响应追加到的WebAPI响应
- 我的WebAPI响应（一个简单的字符串200个状态码）
- 404，从什么样子一个静态文件处理程序从铬
截图：
我的设置是：
- F＃
- 单在Ubuntu 15.10
- xsp4作为Web服务器
- Owin作为路由引擎
正如你从截图中可以看到在浏览器响应的第一行打印出正确的响应（有时是叹息），然后立即在页面上通过标准404页面进行响应。
的启动代码：
type Startup() =
static member RegisterWebApi(config: HttpConfiguration) =
// Configure routing
config.MapHttpAttributeRoutes()
// Configure serialization
config.Formatters.XmlFormatter.UseXmlSerializer <- true
config.Formatters.JsonFormatter.SerializerSettings.ContractResolver <- Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver()
member __.Configuration(builder: IAppBuilder) =
let config = new HttpConfiguration()
Startup.RegisterWebApi(config)
builder.UseWebApi(config) |> ignore
builder.UseErrorPage() |> ignore
控制器代码：
[<RoutePrefix("api")>]
type WordsearchController() =
inherit ApiController()
[<Route("")>]
member this.Get() =
this.Request.CreateResponse<string>(HttpStatusCode.OK, "This is my simple output")
我曾尝试在web.config中删除静态文件处理程序，在启动时使用MVC样式路由映射，以及各种路由属性为控制器。
它似乎像webapi路由和静态文件处理程序都把他们的两分钱到响应，而不是一个覆盖另一个。
由于每从@马克请求，所述请求是一个简单的GET到http://localhost:9000/api，并且响应是：

单不支持的WebAPI异步管道。
我提出单声道请求https://github.com/mono/mono/pull/3048。它使同步执行异步Web api堆栈。
现在，您可以使用WebAPI异步管道和Mono的此修复程序。

谢谢奥列格。我等待合并并释放出诱人的气息。 –
控制器代码是否实际格式化为发布？因为如果是这样，我不明白它是如何编译的。鉴于F＃对空白敏感，发布代码时请确保格式正确。 –
请发布实际的HTTP流量（请求和响应），而不是张贴屏幕快照。从屏幕截图中，我看不到响应*真正*。 HTTP 1.1是纯文本，因此您可以在此处轻松发布。 –
谢谢@mark。我已经添加了详细的回复并在代码中修正了缩进。谢谢你的时间！ –
