python注冊釘釘回調事件的實現

釘釘API文檔：https://ding-doc.dingtalk.com/doc#/serverapi2/skn8ld

釘釘有回調事件流程，有哪些回調？比如：通訊錄回調、審批回調等等，拿通訊錄回調來說，就是當你公司組織架構發生變動時，會自動觸發你自己注冊的回調地址，然后根據回調信息做一些自定義的處理，不得不說，釘釘真的是解決了協同辦公的很多問題，非常nice，但就回調事件來說，每個企業只能注冊一個回調地址，即使你要監聽的是不同的事件、即使還有其他業務線需要用到回調，也只能不多于一個回調，當然這都是出于人家服務多方面考慮的設計，廢話不多說，

好，流程：

一個注冊端向釘釘發送注冊請求，釘釘callback你自己的服務url，必須是公網訪問的地址，并且該地址返回釘釘json數據來告訴釘釘回調成功

注冊成功之后這個地址就可以接收釘釘的回調post請求，做一些自定義處理，記得返回json

好，代碼

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 = '回調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'], # 審批回調 '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': '自定義字符串', '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 刪除回調 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 獲取釘釘token# # dingOBJ.get_token() # todo 獲取回調失敗# dingOBJ.get_fail() # todo 注冊回調 # dingOBJ.regist_call_back() # todo 查詢回調事件 dingOBJ.query_callback() # todo 修改回調事件# dingOBJ.update_call_back() # todo 刪除回調 # dingOBJ.delete_callback()2、回調端：以下示例代碼為python2，django 框架
