Question

I'm trying to serve a folder in the root of my application called assets. I want all files and subfolders within there to be accessible through the url /details/.

fs := http.FileServer(http.Dir("assets"))
http.Handle("/details/", http.StripPrefix("/details/", fs))

I still get 404s for everything. Am I using StripPrefix incorrectly?

To be clear, suppose assets contained test.json. I want that to be accessible from the URL /details/test.json.

Per the above comments double check your paths, permission, user contexts etc.

If you are still stuck, start with this basic setup:

package main

import (
        "log"
        "net/http"
)

func main() {
        fs := http.FileServer(http.Dir("/tmp/assets"))
        http.Handle("/details/", http.StripPrefix("/details/", fs))
        log.Fatal(
                http.ListenAndServe(":8080", nil),
        )   
}

And test with curl etc.

$ find /tmp/assets

/tmp/assets
/tmp/assets/test.json

$ go run ./main.go

$ curl localhost:8080/details/

<a href="test.json">test.json</a>
