kotlin HttpURLConnection发送请求

在kotlin中使用net包提供的HttpURLConnection进行网络请求

POST

private fun post(json: String) {
        Thread {
            var conn: HttpURLConnection? = null
            var out: PrintWriter? = null
            var reader: BufferedReader? = null
            try {
                conn =
                    URL("http://127.0.0.1").openConnection() as HttpURLConnection
                conn.setRequestProperty("accept", "*/*")
                conn.setRequestProperty("connection", "Keep-Alive")
                conn.setRequestProperty("user-agent", System.getProperty("http.agent"))
                conn.doOutput = true
                conn.doInput = true
                conn.connectTimeout = 30 * 1000
                conn.readTimeout = 30 * 1000
                out = PrintWriter(OutputStreamWriter(conn.outputStream, "utf-8"))
                //发送请求
                out.print(json)
                //flush 输出流缓冲
                out.flush()
                reader = BufferedReader(InputStreamReader(conn.inputStream, "utf-8"))
                val bufferResult = StringBuffer()
                reader.use { r ->
                    val temp = r.readLine()
                    if (temp != null) bufferResult.append(temp)
                }
                val responseCode = conn.responseCode
                //请求成功
                if (responseCode == 200) {
                    GLog.p(bufferResult.toString())
                }
            } catch (ex: Exception) {
                ex.printStackTrace()
            } finally {
                out?.let {
                    try {
                        it.close()
                    } catch (exInner: Exception) {
                        exInner.printStackTrace()
                    }
                }
                reader?.let {
                    try {
                        it.close()
                    } catch (exInner: Exception) {
                        exInner.printStackTrace()
                    }
                }
                conn?.let {
                    it.disconnect()
                }
            }
        }.start()
    }

GET
