最近把组内的一个项目对接钉钉审批接口，文中通过示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
最近把组内的一个项目对接钉钉审批接口，通过python3.6。
废话不多说了，上代码：
import requests import json import time from dingtalk.crypto import DingTalkCrypto from django.conf import settings # 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): #

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。
