里，其他插件框架进程是伴随的子进程，因此无法通过内存共享和直接对象传递的方式进行通信，轻雪提供了一个通道<code>Channel</code>用于跨进程通信，你可以通过<code>Channel</code>发送消息给其他进程，也可以监听其他进程的消息。</p><p>例如子进程接收到用户信息需要重启机器人，这时可以通过通道对主进程发送消息，主进程接收到消息后重启对应子进程。</p><h3 id="示例" tabindex="-1"><a class="header-anchor" href="#示例"><span>示例</span></a></h3><p>通道是全双工的，有两种接收模式，但一个通道只能使用一种，即被动模式和主动模式，被动模式由<code>chan.on_receive()</code>装饰回调函数实现，主动模式需调用<code>chan.receive()</code>实现</p><ul><li>创建子进程的同时会初始化一个被动通道和一个主动通道，且通道标识为<code>{process_name}-active</code>和<code>{process_name}-passive</code>，</li><li>主进程中通过<code>get_channel</code>函数获取通道对象</li><li>子进程中导入单例<code>active_channel</code>及<code>passive_channel</code>即可</li></ul><blockquote><p>在轻雪插件中(主进程中)</p></blockquote><div
