关于开发企业微信客户变更事件（https://work.weixin.qq.com/api/doc/90000/90135/92129） 1.已设置了服务器url相关配置 [图片] [图片] 2.但是日志中显示，服务器中能够接收到以下事件类型，但是却接收不到add_external_contact事件。请问怎么会这样子？ "Event":"change_external_contact","ChangeType\":"edit_external_contact" "Event":"change_external_contact","ChangeType\":"add_half_external_contact" "Event":"change_external_contact","ChangeType\":"msg_audit_approved" "Event":"change_external_contact","ChangeType\":"del_follow_user" [图片] [图片]
