    python公司内项目对接钉钉审批流程的实现

    作者:东隅已逝桑榆非晚 时间:2021-09-18 18:43

    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:

            self.corp_id = settings.DINGDING.get("CorpId") #

        # 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。
