'listening' 事件
worker
<cluster.Worker>address
<Object>
从工作进程调用 listen()
后,当服务器上触发 'listening'
事件时,则主进程中的 cluster
也将触发 'listening'
事件。
事件句柄使用两个参数执行,worker
包含工作进程对象,address
对象包含以下连接属性:address
、port
和 addressType
。
如果工作进程正在监听多个地址,则这将非常有用。
cluster.on('listening', (worker, address) => {
console.log(
`A worker is now connected to ${address.address}:${address.port}`);
});
addressType
是以下之一:
4
(TCPv4)6
(TCPv6)-1
(Unix 域套接字)'udp4'
或'udp6'
(UDPv4 或 UDPv6)
worker
<cluster.Worker>address
<Object>
After calling listen()
from a worker, when the 'listening'
event is emitted
on the server, a 'listening'
event will also be emitted on cluster
in the
primary.
The event handler is executed with two arguments, the worker
contains the
worker object and the address
object contains the following connection
properties: address
, port
, and addressType
. This is very useful if the
worker is listening on more than one address.
cluster.on('listening', (worker, address) => {
console.log(
`A worker is now connected to ${address.address}:${address.port}`);
});
The addressType
is one of:
4
(TCPv4)6
(TCPv6)-1
(Unix domain socket)'udp4'
or'udp6'
(UDPv4 or UDPv6)
