Node.js Channel.subscribe(onMessage)用法及代碼示例

channel.subscribe(onMessage)

參數

• onMessage <Function>接收通道消息的處理程序
  • message <any> 消息數據
  • name <string> | <symbol> 頻道名稱

注冊一個消息處理程序以訂閱此頻道。每當消息發布到通道時，此消息處理程序將同步運行。消息處理程序中引發的任何錯誤都將觸發 'uncaughtException' 。

const channel = diagnostics_channel.channel('my-channel');

channel.subscribe((message, name) => {
  // Received data
});const diagnostics_channel = require('node:diagnostics_channel');

const channel = diagnostics_channel.channel('my-channel');

channel.subscribe((message, name) => {
