脚本名为advertising_generate.sh，替换ip，port，username和password

    }

                    String result = processStdout(session.getStdout(), DEFAULTCHART);

                    //如果为得到标准输出为空，说明脚本执行出错了
                    if (result == null) {
                        result = processStdout(session.getStderr(), DEFAULTCHART);
