Suave不显示静态文件

Question

所以我非常简单地设置了我的服务器。如果路径的格式为/article/something，它应该在static文件夹中提供静态文件something.html。出于某种原因，Files.file For部件显然返回了None。我添加了OK "File Displayed" the部件来验证这一点。OK从不执行。

let app =
    choose [
        pathScan "/article/%s" (fun article ->
                                  let name = sprintf "%s.html" article
                                  Console.WriteLine name
                                  Files.file name >=> OK "File Displayed")
    ]

let config =
    { defaultConfig with homeFolder = Some (Path.GetFullPath "./static") }

[<EntryPoint>]
let main args =
    startWebServer config app
    0

有趣的是，Console.WriteLine name行执行得很好，当我执行此命令时，我在控制台窗口中看到了something.html。问题似乎完全是Files.file name返回None。

文件something.html肯定存在于静态文件夹中，所以这不是问题所在。

你知道这是什么原因造成的吗？

以下是解决静态文件服务问题的一些部分

    let troubleShootExtensionPart extensionToCheck :WebPart =
        fun ctx ->
            match extensionToCheck with
            | null | "" -> ServerErrors.INTERNAL_ERROR "Extension Error not supplied, part is not set up correctly"
            | x when not <| x.StartsWith "." -> ServerErrors.INTERNAL_ERROR "Extensions start with a '.', part is not set up correctly"
            | _ ->
                let mtm = ctx.runtime.mimeTypesMap
                match mtm extensionToCheck with
                | None ->
                    sprintf "%s is not supported by the mime types map, compose your mime type with the `defaultMimeTypesMap`" extensionToCheck
                    |> RequestErrors.FORBIDDEN
                | Some x ->
                    sprintf "%s is supported and uses '%s', compression on? : %A" extensionToCheck x.name x.compression
                    |> OK
            |> fun wp -> wp ctx

使用通配符的示例消费，因此如果没有匹配的路由，您将获得一些诊断信息

#if DEBUG
pathScan "/checkExtension/%s" (fun name -> troubleShootExtensionPart name)
// catch all
(fun ctx -> sprintf "404, also homeFolder resolves to %s" (Path.GetFullPath ".") |> RequestErrors.NOT_FOUND |> fun wp -> wp ctx)
#endif
