例如这种格式的json数据怎么获取 record里边的属性值通道二

{"code": 0, "data": {"record": [{"camera_name": "通道二", "channel": 2, "create_time": "2019-08-21 10:39:37", "img_id": "39b7edc6-d733-4df1-865a-b9b47851d965", "img_path": "img/1_39b7edc6-d733-4df1-865a-b9b47851d965.jpg", "lib_id": 1, "lib_name": "test", "lib_type": 1, "person_addr": "123121312", "person_age": "12", "person_gender": "1", "person_idcard": "12131231", "person_name": "测试1", "position": "", "ranking": 1, "similarity": 98, "snap_id": "a3d5d688-d461-4ade-8c06-705da864629d", "snap_path": "record/a3d5d688-d461-4ade-8c06-705da864629d.jpg", "threshold": 85, "trigger": "2019-08-21 10:39:48"}, {"camera_name": "通道二", "channel": 2, "create_time": "2019-08-21 10:39:37", "img_id": "39b7edc6-d733-4df1-865a-b9b47851d965", "img_path": "img/1_39b7edc6-d733-4df1-865a-b9b47851d965.jpg", "lib_id": 1, "lib_name": "test", "lib_type": 1, "person_addr": "123121312", "person_age": "12", "person_gender": "1", "person_idcard": "12131231", "person_name": "测试1", "position": "", "ranking": 1, "similarity": 97, "snap_id": "57dcc971-7c48-4d5e-af2b-e65856097043", "snap_path": "record/57dcc971-7c48-4d5e-af2b-e65856097043.jpg", "threshold": 85, "trigger": "2019-08-21 10:39:46"}], "result_num": 2, "total_num": 2}, "msg": ""}
