如何拉取钉钉的外出、出差审批单

拉取钉钉的外出、出差审批单

出差、外出审批入口如图所示：

钉钉开放平台创建应用

登录钉钉开放平台，并创建钉钉应用用于授权
https://open-dev.dingtalk.com/fe/app#/corp/app

创建应用

设置应用服务器出口IP，也就是白名单IP

可设置多个，一般为了方便调试，除了测试环境主机IP、线上环境主机IP，还要加上用于开发的电脑的公网IP，直接百度“IP”可查看本机公网IP。

其他什么应用首页地址之类的随便填写即可

设置应用权限

一般需要设置OA审批和通讯录管理中的一些权限，可根据实际开发目标开通权限，不知道如何抉择，可以都申请。

开发前提准备

1、应用的appKey，appSecret

2、出差流程code、外出流程code
这两个code最好是主管理员，子管理员不知道能否获取。

加入钉钉的依赖

     <dependency>
            <groupId>com.aliyungroupId>
            <artifactId>alibaba-dingtalk-service-sdkartifactId>
            <version>2.0.0version>

具体的调用方法以及解析方法，就不拿出来了，基本只要在服务器出口IP中，配置本地公网IP，防止出现不在白名单中的类似报错，就可以顺利调用。
