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) { 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 大家有更好的方法歡迎留言分享,以上就是本次共享的內(nèi)容 。還有,提示一下,如果復(fù)制中,缺失jar包,請(qǐng)自行下載,如果找不到,請(qǐng)給我留言,還有,程序是死的,人是活的,怎么方便怎么來(lái) |
