1.首先注册应用，获取 appkey、appsecret
api_url = "https://oapi.dingtalk.com/gettoken?appkey=%s&appsecret=%s"%(appkey,appsecret)
def get_token():
# try:
res = requests.get(api_url)
if res.status_code == 200:
str_res = res.text
token = (json.loads(str_res)).get('access_token')
return token
2.此时拿到的token就是access_token，可以用它来发送请求了
def departList():
# 所有部门信息
url = 'https://oapi.dingtalk.com/department/list?access_token={}'.format(get_token())
ret = json.loads(requests.get(url).text)
department = ret.get('department')
departList = []
for department_info in department:
departdict = {}
departdict['name'] = department_info.get('name')
departdict['id'] = department_info.get('id')
departdict['parentid'] = department_info.get('parentid')
departList.append(departdict)
return departList
