HttpURLConnection及乱码解决

当我们在程序中访问远程服务器的接口时，有时会遇到中文乱码的问题，这里提供一种解决方案。

这里使用InputStreamReader 和BufferedReader

/**
     * 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("POST");
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setRequestProperty("contentType", "utf-8");
            connection.setRequestProperty("Accept-Charset", "utf-8");
            if (connection.getResponseCode() != 200) {
                log.error("连接失败！");
            } else {
                InputStreamReader in = null;
                in = new InputStreamReader(connection.getInputStream(),"utf-8");
                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;
    }
