网络请求HttpUrlConnection的GET/PSOT请求框架

写在前面 :本篇博客单单属于请求网络数据的工具类,可直接粘贴使用public static String postUrlConnect(String urlPath, Map<String, Object> map) {            StringBuffer sbRequest = new StringBuffer();            if (map != null && map.size() > 0) {                for (String key : map.keySet()) {                    sbRequest.append(key + "=" + map.get(key) + "&");                }            }            String request = sbRequest.substring(0, sbRequest.length() - 1);            try {                URL url = new URL(urlPath);                HttpURLConnection httpurl = (HttpURLConnection) url.openConnection();                httpurl.setRequestMethod("POST");                //设置连接主机超时                httpurl.setConnectTimeout(30000);                //设置从主机读取数据超时                httpurl.setReadTimeout(30000);                httpurl.setDoInput(true);                httpurl.setDoOutput(true);            //读取数据                OutputStream os = httpurl.getOutputStream();                os.write(request.getBytes());               //刷新                os.flush();                //判断返回值是否正确                if (httpurl.getResponseCode() == 200) {                    InputStream in = httpurl.getInputStream();                    StringBuffer sb = new StringBuffer();                 //创建字符数组                    byte[] buff = new byte[1024];                    int len = -1;                    while ((len = in.read(buff)) != -1) {                        sb.append(new String(buff, 0, len, "utf-8"));                    }                    //关闭流                    in.close();                    os.close();                    httpurl.disconnect();                    return sb.toString();                } else {                    return null;                }            } catch (Exception e) {                e.printStackTrace();            }            return urlPath;        }        public static String getUrlConnect(String urlPath) {            try {                //获取地址                URL url = new URL(urlPath);                HttpURLConnection httpurl = (HttpURLConnection) url.openConnection();                httpurl.connect();                //判断返回值                if (httpurl.getResponseCode() == 200) {                    InputStream in = httpurl.getInputStream();                    StringBuffer sb = new StringBuffer();                    byte[] buff = new byte[1024];                    int len = -1;                    while ((len = in.read(buff)) != -1) {                        sb.append(new String(buff, 0, len, "utf-8"));                    }                    in.close();                    httpurl.disconnect();                    return sb.toString();                } else {                    return null;                }            } catch (Exception e) {                e.printStackTrace();            }            return null;        }
