python注册钉钉回调事件的实现
目录
1、注册端
2、回调端：以下示例代码为python2，django 框架
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
1、注册端
mport requests, json
class 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())

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

def randam_string(n):
ran_str = ''.join(random.sample(string.ascii_letters + string.digits, n))
return ran_str
# 注册回调
