python公司内项目对接钉钉审批流程的实现
最近把组内的一个项目对接钉钉审批接口，通过python3.6。
钉钉官方文档
废话不多说了，上代码：

# settings.BASE_DIR
class Crypto(object):
def __init__(self, token):
# 随便填的字符串
self.token = token
# 自己生成的43位随机字符串
self.aes_key = settings.DINGDING.get("DINGTALK_AES_TOKEN")
# 钉钉企业ID
self.corp_id = settings.DINGDING.get("CorpId") #
print("corp_id:", self.corp_id)
self.nonce = settings.DINGDING.get("nonce")
self.crypto = DingTalkCrypto(
token=self.nonce,
encoding_aes_key=self.aes_key,
corpid_or_suitekey=self.corp_id
)
def encrypt_success(self):
# 返回加密success
result = self.crypto.encrypt_message(
msg="success",
nonce=self.nonce,
timestamp=int(time.time()*1000)
)
return result

self.process_code = settings.DINGDING.get("APPROVE_PROCESS").get(approve_process)['process_code']
self.aes_key = settings.DINGDING.get("DINGTALK_AES_TOKEN")
self.nonce = settings.DINGDING.get("nonce")

'''

# print(a)
# c = Crypto(a)
# print(c.encrypt_success())
# 注册回调
# print(ding.register_callback("http://xxxx.vaiwan.com/xxx"))
# print(ding.get_callback())
说明：
1 Crypto类用于对接钉钉回调用的。一个公司只有一个corpId，并且一个corpid只能注册一个回调地址。我司有公共组注册好了回调。只要接入公司内的回调即可。所以我实际没有使用到Crypto。
2 在钉钉管理后台中创建应用后会有这三个东西：AgentId、AppKey，AppSecret 。在创建钉钉审批流程，可以从审批流程浏览器中获取到APPROVE_PROCESS。别忘啦给这个流程审批接口权限。这些官方文档有说。
3 配置setting变量：
DINGDING = {
"AgentId": 123,
"AppKey": "xx",
"AppSecret": "xx",
"URL": "https://oapi.dingtalk.com",
"APPROVE_PROCESS": { # process_code
"create_xx": {
"process_code": "abc", # 审批流程的id
},
"DINGTALK_AES_TOKEN": "abc",
"nonce": "abc",
"CorpId": "abc",
}
4 接口形式创建的审批流程，与钉钉管理后台创建的流程有一些不同：
1 不能在不同的审批环节设置不同的抄送人
2 不能审批流程前后有相同的人，不能自动显示成 “自动同意”(管理后台设置成去重后，但是接口指定审批人场景，不支持)
5 其他如：审批内容、或签，会签代码里都有示例。
