本文介绍了一个通过HTTP POST请求获取视频列表的Java方法实现。该方法接收账号和密码作为参数，并向指定的服务端地址发送JSON格式的数据包。如果请求成功，则返回包含视频列表的字符串。

public static String getVideoList(String account,String password)
    {
        String result = "";

        String ipString = getMediaServerAddr();

       String authHost = "http://10.1.11.23:1132/xwvideo/searchVideoList.do";

        try {
            URL url = new URL(authHost);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
             // 设置请求方式
            connection.setRequestMethod("POST");
           // 设置是否向HttpURLConnection输出
            connection.setDoOutput(true);
            // 设置是否从httpUrlConnection读入
            connection.setDoInput(true);
            // 设置是否使用缓存
            connection.setUseCaches(false);
            //设置参数类型是json格式
            connection.setRequestProperty("Content-Type", "application/json;charset=utf-8");
            connection.connect();

            String body = "{account:"+account+",startTime:"+password+"}";
//            String body = requestString;

            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream(), "UTF-8"));
            writer.write(body);
            writer.close();

            int responseCode = connection.getResponseCode();
            if(responseCode == HttpURLConnection.HTTP_OK) {
                //定义 BufferedReader输入流来读取URL的响应
                BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                String line;
                while ((line = in.readLine()) != null) {
                    result += line;
                }
            }

        }catch (Exception ex)
        {
            log.error("Get VideoList Request Failed....");
            log.error(ex.getMessage());
        }

        return result;
    }
