Oops! Looks like we hit a roadblock trying to access the file at ../src/web/views/index.htm. The system

Encountering some peculiar file path issues in my Go project. Here's how the file structure is laid out:

C:/ProjectName/
-------------->bin/
-------------->pkg/
-------------->src/web/
---------------------->main.go
---------------------->controllers/Constants.go
---------------------->content/css/index.css
---------------------->views/index.html

My Go environment variables are set as follows:

GOBIN=C:\ProjectName\bin
GOPATH=C:\ProjectName

In the index.html file, I reference the CSS file using

<link href="/css/index.css"...
, but it fails to locate the css file.
Similarly, in the Constants.go file, I try to access the html file with
const indexFile string = "../src/web/views/index.htm"
, which also proves unsuccessful.

If I access the css file as /content/css/index.css, it works fine. Likewise, referencing the index.html file as "../web/views/index.htm" also resolves the issue.

The predicament lies in the fact that while this approach works on my computer, it causes failures on other team members' machines. Every attempt to make it run smoothly on mine results in breaking for everyone else.

Any insights on identifying the root cause and rectifying this matter would be greatly appreciated.

Thank you,

EDIT 1: Overview of my handlers

router := httprouter.New()
router.GET(basic("/", IndexFunc))

func basic(p string, h func(http.ResponseWriter, *http.Request)) (string, 
httprouter.Handle) {

    return p, wrapHandler(alice.New(context.ClearHandler).ThenFunc(h))
}

func IndexFunc(w http.ResponseWriter, r *http.Request) 
{    
    t, err := template.ParseFiles("../src/web/views/index.htm")
    checkError(err)
    t.Execute(w, nil)
}

References:

alice -> https://github.com/justinas/alice

context -> https://github.com/gorilla/context

The function indexFunc essentially serves the index.html file.

To ensure proper hosting of files, it is important that we review the code you are using. Typically, to serve a directory, I follow this approach:

http.Handle("/content/", http.StripPrefix("/content/", http.FileServer(http.Dir("content")))

With this method:

  • All files within the "content" directory (relative to the application's location) are served at /content/*.
  • The "/content" part of URLs is removed before searching for the file in that directory.

I prefer consolidating all static files into one common directory to simplify this process.

It seems like you might be just using

http.Handle("/", http.Fileserver(http.Dir(""))
, which serves all files based on their paths relative to the working directory.

Edit:

In Go applications, each handler must have its specified path. You can either rearrange the files to match the desired URLs or define multiple URL mappings. In my setup, I usually recommend these handlers:

  1. API handlers under /api defined individually (

    http.HandleFunc("/api/whatever", myHandler)
    )

  2. All static content served from /static/* originating from a single directory (as mentioned earlier). Hence, /content/css/style.css will serve ./content/css/style.css

  3. Any other requests will default to serving "index.html".

    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){ http.ServeFile(w,r,"path/to/index.html") }
