process.send(message[, sendHandle[, options]][, callback])

• message <Object>

• sendHandle <net.Server> | <net.Socket>

• options <Object> 用于参数化某些类型句柄的发送。options 支持以下属性：

  ¥options <Object> used to parameterize the sending of certain types of handles.options supports the following properties:

  • keepOpen <boolean> 当传入 net.Socket 实例时可以使用的值。当为 true 时，套接字在发送过程中保持打开状态。默认值：false。

    ¥keepOpen <boolean> A value that can be used when passing instances of net.Socket. When true, the socket is kept open in the sending process. Default: false.

• callback <Function>

• 返回：<boolean>

  ¥Returns: <boolean>

如果使用 IPC 通道衍生 Node.js，则可以使用 process.send() 方法向父进程发送消息。消息将作为父对象 ChildProcess 对象上的 'message' 事件接收。

¥If Node.js is spawned with an IPC channel, the process.send() method can be used to send messages to the parent process. Messages will be received as a 'message' event on the parent's ChildProcess object.

如果 Node.js 没有使用 IPC 通道衍生，则 process.send 将是 undefined。

¥If Node.js was not spawned with an IPC channel, process.send will be undefined.

消息经过序列化和解析。结果消息可能与最初发送的消息不同。

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