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：

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。
