你有没有觉得很熟悉？

看到这篇代码。。你是什么感觉 ！

看到它 我比较亲切 ，仿佛偶遇故人。。首先我是温习了一遍 ！！照抄 自己写了一遍 ，享受在其中。。

这段代码 让我想起我学习的时候 ，当时一个OutputStream InputStream 混乱纠结了好久 当然了 到现在 要是不看着 可能也写不太好 。。。

在没有用 什么xutils,volley,okhttp,asynck等等之前 ，最初请求 我们就是这样写的 。。

public class NetUtils {
        public static String post(String url, String content) {
            HttpURLConnection conn = null;
            try {

                URL mURL=new URL(url);
                conn= (HttpURLConnection) mURL.openConnection();
                conn.setRequestMethod("POST");
                conn.setReadTimeout(5000);
                conn.setConnectTimeout(10000);
                conn.setDoOutput(true);

                String data = content;
                OutputStream out = conn.getOutputStream();
                out.write(data.getBytes());
                out.flush();
                out.close();


                int responseCode = conn.getResponseCode();
                if (responseCode == 200) {

                    InputStream is = conn.getInputStream();
                    String response = getStringFromInputStream(is);
                    return response;
                } else {
                    throw new NetworkErrorException("response status is "+responseCode);
                }


            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                if (conn != null) {
                    conn.disconnect();// 关闭连接
                }
            }

            return null;
        }

        public static String get(String url) {
            HttpURLConnection conn = null;
            try {
                // 利用string url构建URL对象
                URL mURL = new URL(url);
                conn = (HttpURLConnection) mURL.openConnection();

                conn.setRequestMethod("GET");
                conn.setReadTimeout(5000);
                conn.setConnectTimeout(10000);

                int responseCode = conn.getResponseCode();
                if (responseCode == 200) {

                    InputStream is = conn.getInputStream();
                    String response = getStringFromInputStream(is);
                    return response;
                } else {
                    throw new NetworkErrorException("response status is "+responseCode);
                }

            } catch (Exception e) {
                e.printStackTrace();
            } finally {

                if (conn != null) {
                    conn.disconnect();
                }
            }

            return null;
        }

        private static String getStringFromInputStream(InputStream is)
                throws IOException {
            ByteArrayOutputStream os = new ByteArrayOutputStream();
            byte[] buffer = new byte[1024];
            int len = -1;
            while ((len = is.read(buffer)) != -1) {
                os.write(buffer, 0, len);
            }
            is.close();
            String state = os.toString();// 把流中的数据转换成字符串,采用的编码是utf-8(模拟器默认编码)
            os.close();
            return state;
        }
    }
