如何在fasthttp中使用http.ResponseWriter执行HTML模板等？

I've recently moved from golang net/http to fasthttp owing to rave reviews.

As you know, fasthttp doesn't use (w http.ResponseWriter) but only one syntax which is (ctx *fasthttp.RequestCtx).

I tried using ctx.Write but it didn't work.

So, how can I implement http.ResponseWriter in the code below to excute my html templates? Please also give some explanation so that we could all benefit.

Much Thanks for your help!

package main()

import (
    "html/template"
    "fmt"
    "github.com/valyala/fasthttp"
    )


type PageData struct {
    Title     string
    }   


func init() {
    tpl = template.Must(template.ParseGlob("public/templates/*.html"))
}

m := func(ctx *fasthttp.RequestCtx) {

    switch string(ctx.Path()) {

        case "/":
        idx(ctx)

        default:
        ctx.Error("not found", fasthttp.StatusNotFound)
    }
}

fasthttp.ListenAndServe(":8081", m)
}

func idx(ctx *fasthttp.RequestCtx) {

    pd := new(PageData)
    pd.Title = "Index Page"

    err := tpl.ExecuteTemplate(ctx.write, "index.html", pd)
    if err != nil {
    log.Println("LOGGED", err)
    http.Error(ctx.write, "Internal server error",      http.StatusInternalServerError)
    return
}

}

*fasthttp.RequestCtx implements the io.Writer interface (that's why ctx.Write() exists), which means that you can simply pass ctx as the parameter to ExecuteTemplate():

tpl.ExecuteTemplate(ctx, "index.html", pd)

Also, the http.Error() call will not work, since RequestCtx is not a http.ResponseWriter. Use the RequestCtx's own error function instead:

ctx.Error("Internal server error", http.StatusInternalServerError)
