How is curl's request expressed in HttpURLConnection?

 curl https://api.github.com/user?--user username: [token]

private fun GetUserName(token:String):String{
    var userName=""
    try{
        val url=URL("https://api.github.com/user?--user username:$token")
        // Creating HttpURLConnection Objects for Connections
        var connection —HttpURLConnection=url.openConnection() as HttpURLConnection
        try{
            // Set the connection timeout.
            connection.connectTimeout=100000
            // Set the response data read timeout.
            connection.readTimeout=100000
            // Configure Accept-Language in the header.
            connection.setRequestProperty("Accept-Language", Locale.getDefault().toString())
            // Set Content-Type in Header
            connection.addRequestProperty("Content-Type", "application/json; charset=UTF-8")
            // Configuring Request Methods
            connection.requestMethod="GET"
            // Configuring Not Automatically Allow Redirects
            connection.instanceFollowRedirects=false
            // True if reading data from URL connection
            connection.doInput=true
            // True to write data to URL connection
            connection.doOutput=false
            // CONNECTION
            connection.connect()
            // Obtaining Response Codes
            valcode = connection.responseCode
            // Log.d("Response code is ", code);

            if(code==204){
                Log.d (TAG, "Receive Success")
            }

            // send a response from the server to the standard output
            valreader=BufferedReader(InputStreamReader(connection.getInputStream()))
            var xml=""
            varline —String

            while(reader.readLine()!=null){
                line=reader.readLine()
                xml+=line
                Log.d (TAG, line)
            }

            Log.d(TAG, "Retrieved Information List $xml")
            reader.close()
