请问我尝试更改企业微信通讯录成员信息来触发回调，为何一次编辑资料操作，会访问回调两次甚至三次呢，将本来一次更新的 N 个字段，分为两次甚至三次更新这是什么意思呢？ $this->app->server->push(function ($message) { file_put_contents('root.txt', var_export($message, true), FILE_APPEND); }); // 得到如下结果，为何一次更新操作会触发多次回调和，分为多次更新的呢？ array ( 'ToUserName' => 'xxx', 'FromUserName' => 'sys', 'CreateTime' => '1629287731', 'MsgType' => 'event', 'Event' => 'change_contact', 'ChangeType' => 'update_user', 'UserID' => 'liwenfeng-18234445666', 'Email' => '333@9999.com', )array ( 'ToUserName' => 'xxx', 'FromUserName' => 'sys', 'CreateTime' => '1629287731', 'MsgType' => 'event', 'Event' => 'change_contact', 'ChangeType' => 'update_user', 'UserID' => 'liwenfeng-18234445666', 'Position' => '555', 'Telephone' => '222', 'Address' => '444', )
