python--注册钉钉回调事件（亲测可用）

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',

            '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):

            "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):

        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

2、回调端：以下示例代码为python2，django 框架

encodingAesKey = ''
key = ''
token = '自定义字符串'
appsecret = ''
appkey = ''

api_url = "https://oapi.dingtalk.com/gettoken?appkey=%s&appsecret=%s"%(appkey,appsecret)


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

# 注册回调

    if request.method == 'GET':
        return JsonResponse({'code':200,'msg':'ok'})


    if request.method == 'POST':
        print request.GET
        dingCrypto = DingCrypto(encodingAesKey,key)

        encrpyt11 = dingCrypto.decrypt(encrpyt)

        return JsonResponse(new_data.get('data'))

# 响应回调
