钉钉回调事件(以审批事件为案列)

1.使用官方接口进行调用

1.注册业务接口
钉钉回调事件(以审批事件为案列)_第1张图片
监听事件在官方的说明中可以看见地址:https://ding-doc.dingtalk.com/doc#/serverapi2/skn8ld
监听事件参数位置,下面以审批事件做个说明:

注意:
缺失[‘’]错误

{
	"errcode":71010,
	"errmsg":"POST的JSON数据不包含所需要的参数字段或包含的参数格式非法"
}

调用成功的回调

{
	"errcode":71012,
	"errmsg":"url地址访问异常,错误原因为:org.apache.http.conn.ConnectTimeoutException: Connect to 223.95.85.243:8066 [223.95.85.243/223.95.85.243] failed: connect timed out HttpRequest: curl 'http://223.95.85.243:8066/callback?signature=90e6cd4484ac83997322b4eaf68477450d1093ca×tamp=1591148525407&nonce=sIUPJMaj' -d '{\"encrypt\":\"I5rXe2M+nvAK5YdkOq6RYzXWeV3+LeLOB1xOQvYZCsCPuxonmg/K1Vr+uGu/Ze67fiBvwDNsC/B+c8wcC5MQaGuxZiw6bNm6ii7z70r78b4Wbo+A3icraqygsSMAWRNd\"}' -H 'Content-Type:application/json'    HttpCode:0   HttpReponse:null"
}

2.编写url校验业务代码
下面采用钉钉官方写的方法:

官方架包:
3个都给予给出

将架包加入lib中,引用

Token,ENCODING_AES_KEY为下方的

SUITE_KEY为这个CorpId钉钉回调事件(以审批事件为案列)_第4张图片
地址验证成功后回调

{
	"errcode":0,
	"errmsg":"ok"
}

注:如果断点调试也会发生url验证异常错误,可以输出官方代码中的encryptMsg和plainText查看回调事件

结果为
