常见问题异常：“code”:“invalidParameter.robotCode.notExsit”,“message”:“机器人不存在”
原因：没有发布应用

{
	"code":"invalidParameter.robotCode.notExsit",
	"requestid":"76DABAC0-8ED5-7622-B692-B9E083CB09E9",
	"message":"机器人不存在"
}

1、创建机器人应用

https://open-dev.dingtalk.com/fe/app#/corp/robot

2、开通机器人接口权限

3、一定要发布（否则无法调试调接口）

4、编写工具类

        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>dingtalk</artifactId>
            <version>1.1.88</version>
        </dependency>
