使用 github.com/julienschmidt/httprouter

Question

所以我试图为 html 模板提供静态 css 和 java 脚本，但参数阻碍了我这样做的能力。

这是我的代码

package main

import (

    "net/http"

    "html/template"

    "github.com/julienschmidt/httprouter"

    "fmt"

)

type PageData struct {

    Chapter int

    Page int

    Source string

}

func main(){

    //I'm using the julienschmidt router because it has parameters that I can use

    //Create a router

    router := httprouter.New()

    //Create the route with the parameters

    router.GET("/:chapter/:page",paramHandler)

    //Create the default route last

    router.GET("/",defaultHandler)

    //get all of the static files working

    router.ServeFiles("/:chapter/:page/*filepath",http.Dir("/js/"))

    //http.Handle("/js/",http.StripPrefix("/js/",http.FileServer(http.Dir("./public/js/"))))

    //http.Handle("/viewjs/",http.StripPrefix("/viewjs/",http.FileServer(http.Dir("./public/viewjs/"))))

    //crate a message telling the user which port the server is running on

    fmt.Println("Now serving on port 8080")

    //Start the server on the specified port

    http.ListenAndServe(":8080",router)

}

func defaultHandler(rw http.ResponseWriter,r *http.Request,p httprouter.Params){

    //Parse the html file

    index := template.Must(template.ParseFiles("public/index.html"))

    chapter := 1

    page := 1

    //Get data from server

    //TODO

    //Test Data

    //defaultPage := PageData{Chapter:chapter,Page:page,Source:"http://lokeshdhakar.com/projects/lightbox2/images/image-4.jpg"}

    //Send the html file to the browser

    fmt.Printf("\nThe chapter is %d and the page is %d",chapter,page)

    index.Execute(rw,nil)

}

func paramHandler(rw http.ResponseWriter,r*http.Request,p httprouter.Params){

    index := template.Must(template.ParseFiles("public/index.html"))

    //Get the page parameters

    chapter := p.ByName("chapter")

    page:= p.ByName("page")

    //Get data from server

    //TODO

所以基本上，我想根据章节和页面变量提供不同的图像（这不是我当前的问题，但这是我需要 url 参数的原因），但路由器认为静态文件路径（我用来服务js和css）充满了参数。我试图将“/foo/foo/”添加到html中每个路径的begging中，

我建议你重组你的项目文件├── main.go├── templates/│   ├── index.html├── assets/    ├── js/    └── react/使用以下处理程序router.GET("/", defaultHandler)router.GET("/chapters/:chapter/pages/:page", paramHandler)router.ServeFiles("/assets/*filepath", http.Dir("assets"))并更改您的脚本源以包含完整路径，例如/assets/js/react/build/react.js如果 httprouter 可以匹配路由，事情会容易得多router.GET("/:chapter/:page", paramHandler)router.ServeFiles("/*filepath", http.Dir("assets"))但仅显式匹配：通过此路由器的设计，请求只能匹配一条路由或不匹配路由。https://github.com/julienschmidt/httprouter#features
