判断业主信息标志位 Per_Mark 是否为 "0" （表示当前业主信息发生过变动！暂未同步到微信访客系统）
将为"0"的数据，上传到微信访客系统
接受数据，遍历数据，查看Per_Status 和 Per_AllowVisit 是否为 "0"
如果其中一个值不为"0",则获取当前数据的Per_ContactTel , 去sync_owners 、owners删除对应数据
如果都为"0",则添加到 sync_owners
这里就有个问题，如果有一个人一开始具有权限，并且在微信公众号中注册了业主。
如果被管理员取消了权限之后又开启了权限，那么必须重新去微信公众号注册业主！！
先读取redis 中 newest-visitor表( 存放的是最新的访客openid)
如果存在数据，则 拼接表名 user:openid ,获取访客信息,下发成功后，将newest-visitor表删除
访问接口，获取数据，存入数据库中 go_visitor表
