工作中有个需求，是要把录入的销售机会由系统自动分配给销售，然后对接钉钉给销售人员发送企业消息，通知他进行跟单。

参考资料

1. 获取Access_Token

Access_Token是企业访问钉钉开放平台全局接口的唯一凭证，即调用接口时需携带Access_Token。

对于企业接入来说，AccessToken需要用CorpID和CorpSecret来换取，CorpID是企业在钉钉中的标识；每个企业拥有一个唯一的CorpID，CorpSecret是企业每个微应用的凭证密钥。

注意：token 一段时间后会刷新，因此必须实时动态获取。

2. 创建微应用

比如发送企业消息，需要创建微应用，获取agent_id,步骤如下：

登录OA,点击工作台，选择『自建应用』

进行微应用内容的设置，获取agent_id

3. 根据需求调用对应的API

4. 编写钉钉工具类

import com.dingtalk.api.DingTalkClient;

import com.dingtalk.api.request.CorpMessageCorpconversationAsyncsendRequest;
