                            for (var j = 0; j < items.length; j++) {
                                var item = items[j];
                                str += new Date(item.CreateTime) + ‘  ‘ + item.ErrorInfo + ‘\n‘;

            }
            console.log(str);
        });
    }

阿里云的错误日志是一条对应一行，这样看起来太痛苦，只能自己通过ajax去获取拼接
