.net - 如何在 F# Suave 中路由/商店/类别/%s/品牌/%s？

Question

我不知道如何为这样的路径设置路由器:

/store/category/%s/brand/%s

我有网上商店演示，它适用于简单的 URL，但我不知道如何进行更灵活的配置。

这就是我所拥有的:

type StrPath = PrintfFormat<(string -> string),unit,string,string,string>
// How do this?
type Str2Path = PrintfFormat<(string -> string),unit,string,string,string>

let withParam (key,value) path = sprintf "%s?%s=%s" path key value

module Store =
    //Don't know what put here
    let browseBrand = sprintf "/store/category/%s/brand/%s"
    //This work ok
    let browseCategory : StrPath = "/store/category/%s"
// I need to capture query parameters
let browseBrand cat brand = request (fun r ->
    Views.browse(cat brand))

let webPart = 
    localizeUICulture >>
    choose [
        path Path.Store.overview >=> overview
        pathScan Path.Store.browseBrand browseBrand
        pathScan Path.Store.browseCategory browseCategory

那这个呢？

// note the string tuple as return value
type Str2Path = PrintfFormat<(string -> string -> string),unit,string,string,(string * string)>

module Store =
    // your path
    let browseBrand : Str2Path = "/store/category/%s/brand/%s"

// again, note the tuple as input
let browseBrand (cat, brand) = request (Views.browse(cat brand))

let webPart = 
    localizeUICulture >>
    choose [
        pathScan Store.browseBrand browseBrand
        // ... OMMITED
    ]
