拿到access_token之后,我们便可以进行自己的系统开发了。本章节将以一个实际的例子快速实现房源房间添加,工单添加,设备安装以及设备绑定。 # 2.1 系统开发过程 云丁智能设备管理是基于**房源**为单位的,对应于现实生活中的房源模型。具体说来就是在一个房源中创建房间,然后将相应的智能网关,智能门锁,智能采集器,智能电表和智能水表等添加到对应的房间。 而房源模型的建立,房间的建立以及智能设备添加,到智能设备的管理都遵循着固定的顺序。主要是**添加房源** —> **添加房间 **—> **添加新装工单** —> **云丁交付上门安装与绑定设备** —> **房间设备添加成功** —> **智能设备管理**。 本章节将按照该步骤快速创建一个包含公区和一个房间的房源,并且在公区和房间分别添加一把门锁和一个电表。 # 2.2 项目的建立 创建项目,代码的结构如下: ![](https://img.kancloud.cn/00/52/00524de103aa2fb1274c1a1ea886f677_432x266.png) **注意**:由于本文档的目的是让开发者快速了解与云丁系统对接的操作流程,因此房源数据结构采用json格式,不涉及模型的建立与数据库存储的操作。 apis文件夹主要存放调用云丁系统接口的函数,这一章我们完成的功能主要会调用到房源,房间和工单的接口,因此新建三个文件home.py, room.py, ticket.py。 一下是具体的代码示例: home.py ``` ~~~ import requests def add_home(access_token, country, city, zone, location, block, home_id, home_name): ''' 添加房源 params: access_token: 调用接口凭证 country: 国家 city:城市 zone:区域 location: 具体地址 block: 小区 home_id: 房源id(全局唯一) home_name: 房源名称 ''' url = 'https://saas-openapi.dding.net/v2/add_home' headers = { 'Content-type': 'Application/json', 'User-Agent': 'PostmanRuntime/7.13.0', } payload = { 'access_token': access_token, 'country': country, 'city': city, 'zone': zone, 'location': location, 'block': block, 'home_id': home_id, 'home_name': home_name } response = requests.request('POST', url, headers=headers, json=payload) if response.status_code == 200: return response.json() def get_home_info(access_token, home_id): ''' 获取房源信息 params: access_token: 调用接口凭证 home_id: 房源id(全局唯一) ''' url = 'https://saas-openapi.dding.net/v2/get_home_info' headers = { 'Content-type': 'Application/json', 'User-Agent': 'PostmanRuntime/7.13.0', } payload = { 'access_token': access_token, 'home_id' : home_id } response = requests.request('POST', url, headers=headers, json=payload) if response.status_code == 200: return response.json() ~~~ ``` room.py ``` ~~~ import requests ''' 添加房间 ''' def add_rooms(access_token, home_id, rooms): ''' 添加房间 params: access_token: 调用接口凭证 home_id: 房源id rooms: list类型 [room1, room2, ... roomn] ''' url = 'https://saas-openapi.dding.net/v2/add_rooms' headers = { 'Content-type': 'Application/json', 'User-Agent': 'PostmanRuntime/7.13.0', } payload = { 'access_token': access_token, 'home_id': home_id, 'rooms': rooms } response = requests.request('POST', url, headers=headers, json=payload) if response.status_code == 200: return response.json() ~~~ ``` ticket.py ~~~ import requests ''' 添加工单 ''' def add_ticket(access_token, home_id, service_target, service_type, room_ids, subscribe): ''' 添加工单 params: access_token: 接口调用凭证 home_id: 房源id service_target: 工单服务对象 1:网关 2:门锁 3:电表 service_type: 工单类型 1:安装 2:售后维修 room_ids: list 需要预约或维修的房间 [room1, room2] subscribe: 下单人 dict 需包含:date, time, name, phone date: 预约时间戳 ms time: 100:全天 101:上午 102:下午 name: 下单人姓名 phone: 下单人联系方式 ''' url = 'https://saas-openapi.dding.net/v2/add_ticket' headers = { 'Content-type': 'Application/json', 'User-Agent': 'PostmanRuntime/7.13.0', } payload = { 'access_token': access_token, 'home_id': home_id, 'service_target': service_target, 'service_type': service_type, 'room_ids': room_ids, 'subscribe': subscribe } response = requests.request('POST', url, headers=headers, json=payload) if response.status_code == 200: return response.json() ~~~ # 2.3 房源房间的建立 新建房源模型, vim home_model.py。 ``` from apis.home import add_home, get_home_info from apis.room import add_rooms from apis.ticket import add_ticket class Home: def __init__(self, **kwargs): access_token = kwargs['access_token'] country = kwargs['country'] city = kwargs['city'] zone = kwargs['zone'] location = kwargs['location'] block = kwargs['block'] home_id = kwargs['home_id'] home_name = kwargs['home_name'] res = add_home(access_token, country, city, zone, location, block, home_id, home_name) if 'ErrNo' in res: if res['ErrNo'] == 0: print('home creating successfully!') else: print('home creating failed') def get_home_info(self, **kwargs): access_token = kwargs['access_token'] home_id = kwargs['home_id'] res = get_home_info(access_token, home_id) return res def add_room(self, **kwargs): access_token = kwargs['access_token'] home_id = kwargs['home_id'] rooms = kwargs['rooms'] res = add_rooms(access_token, home_id, rooms) return res def add_ticket(self, **kwargs): access_token = kwargs['access_token'] home_id = kwargs['home_id'] service_target = kwargs['service_target'] service_type = kwargs['service_type'] room_ids = kwargs['room_ids'] subscribe = kwargs['subscribe'] res = add_ticket(access_token, home_id, service_target, service_type, room_ids, subscribe) return res ``` 创建Home类,并实现添加房间(add_home),获取房源信息(get_home_info),添加工单(add_ticket)等方法。 接下来创建房源, vim main.py。 ``` from home_model import Home def main(): #创建房源 home_data = { 'access_token' : '6afc3f360e04f806244af07c6c5eca1cee6065e83565e107fc4896b55ce8f735df5bd9a7d3c5e1e2f96f1fdd1c2ea52483ec2e10e5cc38517a17b1d4aff2ceff', 'country' : '中国', 'city' : '深圳', 'zone' : '南山区', 'location' : '深南大道118号', 'block' : '万科一期', 'home_id' : 'testhomeid123', 'home_name' : '18栋1501' } home = Home(**home_data) if __name__ == '__main__': main() ``` ``` ``` 将需要创建的房源参数组装成Json格式,初始化Home类,成功创建房源。返回结果: ``` home creating successfully! ``` # 2.4 创建房间 我们在刚刚创建的房源home上,使用add_home方法添加房间,vim main.py 其代码示例: ``` room_data = { 'access_token' : '6afc3f360e04f806244af07c6c5eca1cee6065e83565e107fc4896b55ce8f735df5bd9a7d3c5e1e2f96f1fdd1c2ea52483ec2e10e5cc38517a17b1d4aff2ceff', 'home_id' : 'testhomeid123', 'rooms' : [ { 'room_id':'0001', 'room_name':'房间1' } ] } res = home.add_room(**room_data) print(res) ``` 房间成功创建,其返回结果为: ``` {'ReqID': '1SBR3NWtqmY', 'ErrNo': 0, 'ErrMsg': ''} ``` # 2.5 添加工单 接着我们使用add_ticket方法添加工单,vim main.py ``` ticket_data = { 'access_token' : '6afc3f360e04f806244af07c6c5eca1cee6065e83565e107fc4896b55ce8f735df5bd9a7d3c5e1e2f96f1fdd1c2ea52483ec2e10e5cc38517a17b1d4aff2ceff', 'home_id' : 'testhomeid123', 'service_target' : 2, #2.门锁 'service_type' : 1, #1.新装工单 'room_ids' : ['0001', 'testhomeid123'], 'subscribe' : { 'date' : 1567094400000, 'time' : 102, 'name' : 'zengjia', 'phone' : '18620190127' } } res = home.add_ticket(**ticket_data) print(res) ``` 工单接口字段的含义: ``` params: access_token: 接口调用凭证 home_id: 房源id service_target: 工单服务对象 1:网关 2:门锁 3:电表 service_type: 工单类型 1:安装 2:售后维修 room_ids: list 需要预约或维修的房间 [room1, room2] subscribe: 下单人 dict 需包含:date, time, name, phone date: 预约时间戳 ms time: 100:全天 101:上午 102:下午 name: 下单人姓名 phone: 下单人联系方式 ``` 添加工单成功后,我们能从返回的结果的ticket_id字段中拿到工单编号 ``` {'ReqID': '1SBR3ZfKpV6', 'ErrNo': 0, 'ErrMsg': '', 'ticket_id': 'ISLK1908301908503'} ``` # 2.6 事件回调与主动轮询 当添加完工单后,云丁交付团队便会根据工单前往现场安装绑定设备,那么我们得知设备已经绑定成功,可以进行管理了呢?主要是两种方式:事件回调与主动轮询。 具体说明之前,先解释下**事件**。当我们对只能设备进行操作时,由于网络IO耗时,所以采取异步操作。当设备操作成功便会将该信息回调给系统,云丁将这种由设备产生的回调称为**事件**,如:绑定事件。 **1**.事件回调,在第一章申请对接的时候便填写过异步事件的回调地址,当有设备事件发生时,云丁系统便会将设备事件回调给商户对接的系统。云丁系统将对商户的回调url发起http请求。商户系统收到http请求之后,解析事件并能够知晓设备已经绑定成功。 **2**. 主动轮询get_home_info下面的devices字段,如果不为空,则说明设备已经添加成功。(注意:这里只是为了演示,并不考虑系统的效率问题,实际生产环境请使用解析事件的方法。) vim main.py ``` while True: res = home.get_home_info(**search_data) if 'result'in res: if 'devices'in res: if len(res['result']['devices']) != 0: for device in res['result']['devices']: print(device) break print('设备添加完毕') ``` 当设备都绑定成功后,get_home_info返回的结果如下: ``` { "ReqID": "1SC5R5uFrIu", "ErrNo": 0, "ErrMsg": "", "result": { "home_id": "testhomeid123", "home_name": "18栋1501", "location": "深南大道118号", "description": "", "home_type": 2, "province": "广东省", "city": "深圳市", "zone": "南山区", "block": "万科一期", "rooms": [ { "room_id": "testhomeid123", "room_name": "公区", "description": "", "sp_state": 1, "install_state": 4 }, { "room_id": "0001", "room_name": "房间1", "description": "", "sp_state": 1, "install_state": 4 } ], "devices": [ { "type": "lock", "sn": "lkjl0019180300779045", "uuid": "8dd9127be919024ba6b2dadd35ea4ff6", "device_id": 534906033, "description": "lock01", "room_id": "testhomeid123", "onoff": 1, "is_out": true, "center_uuid": "ccec6095685126a25213657764f7eb2f", "model_name": "D2F", "model": "lk-19", "power": 94 }, { "type": "gateway", "sn": "cnjl0003180100385967", "uuid": "ccec6095685126a25213657764f7eb2f", "device_id": 2043770700, "description": "网关", "room_id": "testhomeid123", "onoff": 1, "is_out": true, "model_name": "G2", "model": "cn-03" }, { "type": "lock", "sn": "lkjl0026190002800173", "uuid": "157c4b2bfc87abe316378b42cde86141", "device_id": 1632908514, "description": "lock02", "room_id": "0001", "onoff": 1, "center_uuid": "ccec6095685126a25213657764f7eb2f", "model_name": "D3", "model": "lk-26", "power": 0 } ], "lease_type": 1 } } ``` devices字段已经有绑定的设备了。后面还需要安装新设备也是采用相同的方法。
