哨兵系统 ---钉钉群消息推送
前言：
之前哨兵系统提醒只是在前台使用声音提醒，现在把消息推送到值班人员群里。避免值班人员在前台，专注写代码。忽略了铃声，还有一点铃声确实有点打扰其他同事工作。所以下一个版本哨兵系统，的确闹铃可以完全取消，替换成群消息提醒。
下面是钉钉群消息推送的代码
目录
页面调用代码
//声音提醒 这段代码放在lable框的内容改变事件里
try
{
System.Media.SoundPlayer sndPlayer = new System.Media.SoundPlayer(Application.StartupPath + @"/pm3.wav");
if (label_similarity.Text == "Stranger(陌生人)")
{
sndPlayer.PlayLooping();
//创建群发送消息
AccessToken.SendMsg(textBox1.Text,textBox2.Text);
}
else
{
sndPlayer.Stop();
}业务实现代码
