说明：使用 HttpURLConnection 创建连接，测试时是从 main 方法调用，没有中文乱码情况，但是当启动服务器后，从远程服务器获取到的数据却乱码了，于是便改成下面的，仅供 can'kao
- 出现乱码的代码：
| |
| * 从 xx 系统拉取用户信息 |
| * @param userAccount |
| * @return |
| */ |
| public static String getUserInfo(String userAccount,String pathType) { |
| String[] serverInfo = getServerInfoForTokenValid(getUserInfo); |
| String serverPath = composeServerPath(serverInfo,userAccount,pathType); |
| |
| String result = ""; |
| HttpURLConnection connection = null; |
| |
| try { |
| URL url = new URL(serverPath); |
| connection = (HttpURLConnection) url.openConnection(); |
| connection.setDoOutput(true); |
| connection.setRequestMethod("GET"); |
| connection.setRequestProperty("Content-Type", "application/json"); |
| Scanner scanner; |
| if (connection.getResponseCode() != 200) { |
| scanner = new Scanner(connection.getErrorStream()); |
| } else { |
| scanner = new Scanner(connection.getInputStream()); |
| } |
| scanner.useDelimiter("\\Z"); |
| while (scanner.hasNext()){ |
| result = scanner.next(); |
| } |
| scanner.close(); |
| }catch (Exception e){ |
| e.printStackTrace(); |
| }finally { |
| if (connection != null) |
| connection.disconnect(); |
| } |
| |
| return result; |
| } |
- 修改后的代码：
| |
| * 从 xx 系统拉取用户信息 |
| * @param userAccount |
| * @return |
| */ |
| public static String getUserInfo(String userAccount,String pathType) { |
| String[] serverInfo = getServerInfo(getUserInfo); |
| String serverPath = composeServerPath(serverInfo,userAccount,pathType); |
| |
| String result = ""; |
| HttpURLConnection connection = null; |
| |
| try { |
| URL url = new URL(serverPath); |
| connection = (HttpURLConnection) url.openConnection(); |
| connection.setDoOutput(true); |
| connection.setRequestMethod(GpsConstants.HTTP_REQUEST_METHOD_GET); |
| connection.setRequestProperty("Content-Type", "application/json"); |
| connection.setRequestProperty("contentType", GpsConstants.ENCODING_UTF8); |
| connection.setRequestProperty("Accept-Charset", GpsConstants.ENCODING_UTF8); |
| if (connection.getResponseCode() != 200) { |
| log.error("连接失败！"); |
| } else { |
| InputStreamReader in = null; |
| in = new InputStreamReader(connection.getInputStream(),GpsConstants.ENCODING_UTF8); |
| BufferedReader bufferedReader = new BufferedReader(in); |
| |
| StringBuffer stringBuffer = new StringBuffer(); |
| String line = null; |
| while ((line = bufferedReader.readLine()) != null) { |
| stringBuffer.append(line); |
| } |
| result = stringBuffer.toString(); |
| } |
| }catch (Exception e){ |
| e.printStackTrace(); |
| }finally { |
| if (connection != null) |
| connection.disconnect(); |
| } |
| |
| return result; |
| } |
