正常的结构

返回的数据：多了好多逗号啊，帮我看看

fun connect() : String {
        var result: InputStream? = null
        var final: String? = null
        var bufferedReader: BufferedReader? = null
        try {
            val url = URL("http://dbg.wplinks.xyz/test/data.json")
            val connect = url.openConnection() as HttpURLConnection
            connect.requestMethod = "GET"
            connect.connectTimeout = 10000
            connect.connect()

            if (connect.responseCode == 200) {
                result = connect.inputStream
                val reader = InputStreamReader(result,"UTF-8")
                bufferedReader = BufferedReader(reader)
                final = bufferedReader.readLines().toString()
                Log.d(TAG, "网络请求成功，result： $final")
            } else {
                Log.d(TAG, " inputStream: 请求失败 ")
                return ""
            }
        }catch (e: Exception) {
            Log.d(TAG, "  请求异常： $e ")
        }
        return final!!
    }
