请登录WEB后台，在调试设备中，找到设置”设备状态“回调地址(仅支持新版“人脸识别”门禁系统)，预先设定好自己的回调地址,并下发到设备上才能生效。

在回调地址中，设置以【POST】方式接收参数名【callback】;

◆ 通用版自行开锁返回代码：

{"code":"900","devid":"610001","status":"人脸识别成功","addtime":"2018-03-17 17:31:12","uid":"15602898989"}
{"code":"901","devid":"610001","status":"开锁成功","addtime":"2018-03-17 17:31:12","uid":"15602898989","type":"人脸识别"}

提示：为方便开发者需要，从2019年4月11日之后的非梯控版本将增加接收开锁功能，回调地址处理完业务逻辑之后，直接按下列格式返回：
{"code":"900","devid":"610001","lockid":"01","uid":"15602898989","result":"1"} 其中result中的1表示开锁，0表示不开锁。

◆ 酒店版自行开锁返回代码：

{"code":"900","devid":"610001","status":"人脸识别成功","addtime":"2018-03-17 17:31:12","uid":"15602898989"}
{"code":"901","devid":"610001","status":"开锁成功","addtime":"2018-03-17 17:31:12","uid":"15602898989","type":"人脸识别"}
如需要开锁操作，直接返回1，否则返回0

◆ 梯控版自行开锁返回代码：

1、用户人脸识别成功会向开发者自定义回调地址推送：
{"code":"900","devid":"610001","status":"人脸识别成功","addtime":"2018-03-17 17:31:12","uid":"15602898989"}
2、回调地址处理完业务逻辑之后，可按如下格式返回需解锁编号：
一层：{"code":"900","devid":"610001","lockid":"01","uid":"15602898989","result":"1"}
多层：{"code":"900","devid":"610001","lockid":"01,07,09","uid":"15602898989","result":"1"}
其中result中的1表示开锁，0表示不开锁，lockid表示解锁楼层编号，如果有多个lockid，请以英文逗号分隔，如超过9个，系统默认解锁全部。

◆ 储物柜版自行开锁返回代码：

1、用户人脸识别成功会向开发者自定义回调地址推送：
    {"code":"900","devid":"610001","status":"人脸识别成功","flag":"01","addtime":"2018-03-17 17:31:12","uid":"15602898989"}，其中Flag的01表示存储操作，02表示退柜操作

2、回调地址处理完业务逻辑之后，然后根据用户的操作类型，直接按下列格式返回
    (1)存储操作
    {"code":"900","devid":"610001","lockid":"01","flag":"01","uid":"15602898989","result":"1"}
    (2)退柜操作
    {"code":"900","devid":"610001","lockid":"01","flag":"02","uid":"15602898989","result":"1"}
    其中result中的1表示开锁，0表示不开锁。lockid中的01表示锁编号

3、用户开锁成功向开发者自定义回调地址推送
    {"code":"901","devid":"610001","status":"开锁成功","flag":"01","lockid":"01","addtime":"2018-03-17 17:31:12","uid":"15602898989"}表示存储操作开锁成功
    {"code":"901","devid":"610001","status":"开锁成功","flag":"02","lockid":"01","addtime":"2018-03-17 17:31:12","uid":"15602898989"}表示退柜操作开锁成功
