java代碼中如何實現http訪問

大概的實現就是 請求http 通過 IO 流 參數 傳遞與接收 代碼如下

public String httpsRequest(String requestUrl, String requestMethod, String output) {try {URL url = new URL(requestUrl);HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();connection.setDoOutput(true);connection.setDoInput(true);connection.setUseCaches(false);connection.setRequestMethod(requestMethod);if (null != output) {OutputStream outputStream = connection.getOutputStream();outputStream.write(output.getBytes("UTF-8"));outputStream.close();}// 從輸入流讀取返回內容InputStream inputStream = connection.getInputStream();InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");BufferedReader bufferedReader = new BufferedReader(inputStreamReader);String str = null;StringBuffer buffer = new StringBuffer();while ((str = bufferedReader.readLine()) != null) {buffer.append(str);}bufferedReader.close();inputStreamReader.close();inputStream.close();inputStream = null;connection.disconnect();return buffer.toString();} catch (Exception ex) {ex.printStackTrace();}return "";}

代碼一目了然
