tracingChannel.unsubscribe(subscribers)

• subscribers <Object> TracingChannel 通道 个订阅者的集合
  • start <Function> start 活动 订阅者
  • end <Function> end 活动 订阅者
  • asyncStart <Function> asyncStart 活动 订阅者
  • asyncEnd <Function> asyncEnd 活动 订阅者
  • error <Function> error 活动 订阅者
• 返回：<boolean> true 表示所有处理程序都已成功取消订阅，false 表示否则。

帮助取消订阅一组函数对应的通道。这与对每个通道单独调用 channel.unsubscribe(onMessage) 相同。

🌐 Helper to unsubscribe a collection of functions from the corresponding channels. This is the same as calling channel.unsubscribe(onMessage) on each channel individually.

import diagnostics_channel from 'node:diagnostics_channel';

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

channels.unsubscribe({
  start(message) {
    // Handle start message
  },
  end(message) {
    // Handle end message
  },
  asyncStart(message) {
    // Handle asyncStart message
  },
  asyncEnd(message) {
    // Handle asyncEnd message
  },
  error(message) {
    // Handle error message
  },
});const diagnostics_channel = require('node:diagnostics_channel');

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

channels.unsubscribe({
  start(message) {
    // Handle start message
  },
  end(message) {
    // Handle end message
  },
  asyncStart(message) {
    // Handle asyncStart message
  },
  asyncEnd(message) {
    // Handle asyncEnd message
  },
  error(message) {
    // Handle error message
  },
});拷贝
