[SOLVED] Go Static Files Serve giving 404 in Linux

Go Static Files Serve giving 404 in Linux

I have a Simple Web Server in Go as below:

func webServerWay() {

    r := mux.NewRouter()
    
    //File Upload Code
    r.HandleFunc("/upload", uploadFile).Methods("POST")
    
    //Test Message
    r.HandleFunc("/test", test).Methods("GET")

    r.PathPrefix("/site/").Handler(http.StripPrefix("/site/", http.FileServer(http.Dir("site"))))


if err := http.ListenAndServe(":8010", r); err != nil {
        log.Fatal("ListenAndServe: ", err)
    }
}

Simple Test Function looks as below: It's A Simple Function to see if the endpoint is reachable.

func test(w http.ResponseWriter, r *http.Request) {
    fmt.Fprint(w, "Welcome it Works!")
}

Site Structure is:

├── go.mod
├── go.sum
├── main.go
└── site
    ├── dist
    └── index.html

The Application Works Perfectly in my local dev environment i.e. Mac OS:

Ajay@apples-MacBook-Air:/$ curl localhost:8010/test
Welcome it Works!
Ajay@apples-MacBook-Air:/$ curl localhost:8010/site/
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <title>gAnalytics</title>
   
  </head>
  <body>
    <div id="root"></div>
  </body>
  <script defer src="./dist/appXYZ.min.js"></script></head>
</html>

But When I Create a Build for Linux(Ubuntu 20.04)x64

GOOS=linux GOARCH=386 go build -o gApp24v1.linux main.go

And run the code in Linux:

sudo ./gApp24v1.linux

The Static Site Serving Doesn't Work, But I can reach the Test Endpoint:

root@gapp24:/home/ajay/app# curl localhost:8010/test
Welcome it Works!
root@gapp24:/home/ajay/app#  curl localhost:8010/site/
404 page not found

I have tried multiple ways of code in static file handler seeing other answers and reading the document but it works in my macOS and not my Linux Machine.

Any Suggestions!

Also the netstat in my Linux(Ubuntu machine) is below:

root@gapp24:/home/ajay/app# netstat -plnt

Solution

When Deploying the build file, the respective static files need to be also moved accordingly:

Here gApp24v1.linux is the build for Linux. The static files containing folder site needs to be also placed in the respective path:

.
├── gApp24v1.linux
└── site
    ├── dist
    │   ├── appXYZ.min.js
    └── index.html
