      Java獲取http和https協(xié)議返回的json數(shù)據(jù)

       青_春 2017-05-19

      現(xiàn)在很多公司都是將數(shù)據(jù)返回一個(gè)json,而且很多第三方接口都是返回json數(shù)據(jù),而且還需要使用到http協(xié)議,http協(xié)議是屬于為加密的協(xié)議,而https協(xié)議需要SSL證書,https是將用戶返回的信息加密處理,然而我們要獲取這些數(shù)據(jù),就需要引入SSL證書?,F(xiàn)在我提供兩個(gè)方法,幫助各位如何獲取http和https返回的數(shù)據(jù)。

      獲取http協(xié)議的數(shù)據(jù)的方法,如下:

      public static JSONObject httpRequest(String requestUrl, String requestMethod) {
              JSONObject jsonObject = null;
              StringBuffer buffer = new StringBuffer();
              try {

                  URL url = new URL(requestUrl);
                  // http協(xié)議傳輸
                  HttpURLConnection httpUrlConn = (HttpURLConnection) url.openConnection();

                  httpUrlConn.setDoOutput(true);
                  httpUrlConn.setDoInput(true);
                  httpUrlConn.setUseCaches(false);
                  // 設(shè)置請(qǐng)求方式(GET/POST)
                  httpUrlConn.setRequestMethod(requestMethod);

                  if ("GET".equalsIgnoreCase(requestMethod))
                      httpUrlConn.connect();
                  // 將返回的輸入流轉(zhuǎn)換成字符串
                  InputStream inputStream = httpUrlConn.getInputStream();
                  InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
                  BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

                  String str = null;
                  while ((str = bufferedReader.readLine()) != null) {
                      buffer.append(str);
                  }
                  bufferedReader.close();
                  inputStreamReader.close();
                  // 釋放資源
                  inputStream.close();
                  inputStream = null;
                  httpUrlConn.disconnect();
                  jsonObject = JSONObject.fromObject(buffer.toString());
              } catch (Exception e) {
                  e.printStackTrace();
              }
              return jsonObject;
          }

      獲取https協(xié)議的數(shù)據(jù)的方法,如下:

      public static JSONObject httpsRequest(String requestUrl, String requestMethod, String outputStr) {
              JSONObject jsonObject = null;
              StringBuffer buffer = new StringBuffer();
              try {
                  // 創(chuàng)建SSLContext對(duì)象,并使用我們指定的信任管理器初始化
                  TrustManager[] tm = { new MyX509TrustManager() };
                  SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
                  sslContext.init(null, tm, new java.security.SecureRandom());
                  // 從上述SSLContext對(duì)象中得到SSLSocketFactory對(duì)象
                  SSLSocketFactory ssf = sslContext.getSocketFactory();

                  URL url = new URL(requestUrl);
                  HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
                  httpUrlConn.setSSLSocketFactory(ssf);

                  httpUrlConn.setDoOutput(true);
                  httpUrlConn.setDoInput(true);
                  httpUrlConn.setUseCaches(false);
                  // 設(shè)置請(qǐng)求方式(GET/POST)
                  httpUrlConn.setRequestMethod(requestMethod);

                  if ("GET".equalsIgnoreCase(requestMethod))
                      httpUrlConn.connect();

                  // 當(dāng)有數(shù)據(jù)需要提交時(shí)
                  if (null != outputStr) {
                      OutputStream outputStream = httpUrlConn.getOutputStream();
                      // 注意編碼格式,防止中文亂碼
                      outputStream.write(outputStr.getBytes("UTF-8"));
                      outputStream.close();
                  }

                  // 將返回的輸入流轉(zhuǎn)換成字符串
                  InputStream inputStream = httpUrlConn.getInputStream();
                  InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
                  BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

                  String str = null;
                  while ((str = bufferedReader.readLine()) != null) {
                      buffer.append(str);
                  }
                  bufferedReader.close();
                  inputStreamReader.close();
                  // 釋放資源
                  inputStream.close();
                  inputStream = null;
                  httpUrlConn.disconnect();
                  jsonObject = JSONObject.fromObject(buffer.toString());
              } catch (ConnectException ce) {
                  log.error("Weixin server connection timed out.");
              } catch (Exception e) {
                  log.error("https request error:{}", e);
              }
              return jsonObject;

          }

      獲取https協(xié)議的數(shù)據(jù)和獲取http協(xié)議的區(qū)別在于

         // 創(chuàng)建SSLContext對(duì)象,并使用我們指定的信任管理器初始化
                  TrustManager[] tm = { new MyX509TrustManager() };
                  SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
                  sslContext.init(null, tm, new java.security.SecureRandom());
                  // 從上述SSLContext對(duì)象中得到SSLSocketFactory對(duì)象
                  SSLSocketFactory ssf = sslContext.getSocketFactory();

                  URL url = new URL(requestUrl);
                  HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
                  httpUrlConn.setSSLSocketFactory(ssf);
