python注册钉钉回调事件的实现

钉钉API文档：https://ding-doc.dingtalk.com/doc#/serverapi2/skn8ld

钉钉有回调事件流程，有哪些回调？比如：通讯录回调、审批回调等等，拿通讯录回调来说，就是当你公司组织架构发生变动时，会自动触发你自己注册的回调地址，然后根据回调信息做一些自定义的处理，不得不说，钉钉真的是解决了协同办公的很多问题，非常nice，但就回调事件来说，每个企业只能注册一个回调地址，即使你要监听的是不同的事件、即使还有其他业务线需要用到回调，也只能不多于一个回调，当然这都是出于人家服务多方面考虑的设计，废话不多说，

好，流程：

一个注册端向钉钉发送注册请求，钉钉callback你自己的服务url，必须是公网访问的地址，并且该地址返回钉钉json数据来告诉钉钉回调成功

注册成功之后这个地址就可以接收钉钉的回调post请求，做一些自定义处理，记得返回json

好，代码

mport requests, jsonclass DingDingCallBack(object): def __init__(self):self.appsecret=’’self.appkey=’’self.api_url = 'https://oapi.dingtalk.com/gettoken?appkey=%s&appsecret=%s'%(self.appkey,self.appsecret)self.aes_key = ''self.callbackUrl = '回调url'self.headers = { ’Content-Type’: ’application/json’, ’User-Agent’: ’Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.96 Safari/537.36’, ’username’:’zhangsan’, ’password’:’123456’} def get_token(self):res = requests.get(self.api_url)if res.status_code == 200: str_res = res.text token = (json.loads(str_res)).get(’access_token’) return token def regist_call_back(self):url = ’https://oapi.dingtalk.com/call_back/register_call_back?access_token={ACCESS_TOKEN}’.format(ACCESS_TOKEN=self.get_token())data = { 'call_back_tag': ['bpms_task_change', 'bpms_instance_change'], # 审批回调 'token': 'qxN3cm', 'aes_key': self.aes_key, 'url':self.callbackUrl, }data1 = json.dumps(data)response = requests.post(url, headers=self.headers, data=data1)print(response)print(response.text) def query_callback(self):url = ’https://oapi.dingtalk.com/call_back/get_call_back?access_token={ACCESS_TOKEN}’.format(ACCESS_TOKEN=self.get_token())response = requests.get(url, headers=self.headers, )print(response)print(response.text) def update_call_back(self):url = ’https://oapi.dingtalk.com/call_back/update_call_back?access_token={}’.format(self.get_token())data = { 'call_back_tag': ['bpms_task_change', 'bpms_instance_change','user_add_org','user_leave_org','org_dept_create','org_dept_modify','org_dept_remove'], 'token': '自定义字符串', 'aes_key': self.aes_key, 'url':self.callbackUrl }data1 = json.dumps(data)response = requests.post(url, headers=self.headers, data=data1)print(response)print(response.text) def get_fail(self):url = ’https://oapi.dingtalk.com/call_back/get_call_back_failed_result?access_token={}’.format(self.get_token())response = requests.get(url, headers=self.headers, )print(response.text)# todo 删除回调 def delete_callback(self):url = ’https://oapi.dingtalk.com/call_back/delete_call_back?access_token={ACCESS_TOKEN}’.format(ACCESS_TOKEN=self.get_token())result = requests.get(url)print(result)print(result.text)#if __name__ == ’__main__’: dingOBJ = DingDingCallBack() # todo 获取钉钉token# # dingOBJ.get_token() # todo 获取回调失败# dingOBJ.get_fail() # todo 注册回调 # dingOBJ.regist_call_back() # todo 查询回调事件 dingOBJ.query_callback() # todo 修改回调事件# dingOBJ.update_call_back() # todo 删除回调 # dingOBJ.delete_callback()2、回调端：以下示例代码为python2，django 框架
