I am installing the app using docker on my laptop. I get 301 when trying to upload a file.
curl -v --upload-file ./hello.txt http://localhost:8080/hello.txt

Currently there is a redirect checking if the connection is secure. If not then it will redirect to https://transfer.sh/. Will work on a solution to disable the check.

In the mean time, you can workaround this issue by removing the RedirectHandler in main.go, by changing:

Handler: handlers.PanicHandler(LoveHandler(RedirectHandler(handlers.LogHandler(r, handlers.NewLogOptions(log.Printf, "_default_")))), nil),

to

Handler: handlers.PanicHandler(LoveHandler(handlers.LogHandler(r, handlers.NewLogOptions(log.Printf, "_default_"))), nil),

Just ran into this issue myself, the code for the redirect handler is looking for a host of 127.0.0.1 in handlers.go

func RedirectHandler(h http.Handler) http.HandlerFunc {
    return func(w http.ResponseWriter, r *http.Request) {
        if r.URL.Path == "/health.html" {
        } else if ipAddrFromRemoteAddr(r.Host) == "127.0.0.1" {
        } else if strings.HasSuffix(ipAddrFromRemoteAddr(r.Host), ".elasticbeanstalk.com") {
        } else if ipAddrFromRemoteAddr(r.Host) == "jxm5d6emw5rknovg.onion" {
        } else if ipAddrFromRemoteAddr(r.Host) == "transfer.sh" {
            if r.Header.Get("X-Forwarded-Proto") != "https" && r.Method == "GET" {
                http.Redirect(w, r, "https://transfer.sh"+r.RequestURI, 301)
                return
            }
        } else if ipAddrFromRemoteAddr(r.Host) != "transfer.sh" {
            http.Redirect(w, r, "https://transfer.sh"+r.RequestURI, 301)
            return
        }

        h.ServeHTTP(w, r)
    }
}

Changing my curl command to curl -v --upload-file ./hello.txt http://127.0.0.1:8080/hello.txt resolves the issue for me

I did it like https://github.com/mapio/transfer.sh/blob/master/transfersh-server/main.go#L172 and it now works!

[But I had to clean the browser caches to force it to forget the old "moved permanently"… dunno why!]

This actually happens not only for an upload, but even accessing to the homepage!

I hope you'll fix it because I'd like to run this on a private network!
