'message' 事件

当子进程使用 process.send() 发送消息时会触发 'message' 事件。

消息通过序列化和解析进行传递。 收到的消息可能跟最初发送的不完全一样。

如果在衍生子进程时使用了 serialization 选项设置为 'advanced',则 message 参数可以包含 JSON 无法表示的数据。 详见高级序列化

The 'message' event is triggered when a child process uses process.send() to send messages.

The message goes through serialization and parsing. The resulting message might not be the same as what is originally sent.

If the serialization option was set to 'advanced' used when spawning the child process, the message argument can contain data that JSON is not able to represent. See Advanced serialization for more details.
