IPC API

安装

npm install @cutos/core

引入依赖

import {CoreAPI} from '@cutos/core';

CoreAPI.getIPC

获取IPC实例对象

let ipc = CoreAPI.getIPC([destAddress]);

• destAddress: 可选参数，目标IP地址，用于设备间进程通信;
  • 不传参数：用于本地监听
  • 传入目标 IP：用于跨设备通信

传入目标 IP：用于跨设备通信

ipc.sendTo

发送IPC信息

ipc.sendTo(channel, args, callback = null);

• channel: 频道名称
• args: 发送的信息
• callback: 回调函数

ipc.on

监听IPC

ipc.on(channel, listener);

• channel: 频道名称
• listener: 监听函数 (args, respond)

本地设备通信举例:

举例1（不含返回值）:

import {CoreAPI} from '@cutos/core';

CoreAPI.init(null, (result, error) => {
    if (!error) {
        let channel1 = 'channel1';
        let ipc = CoreAPI.getIPC();
        //监听IPC信息
        ipc.on(channel1, (args) => {
            console.log('on', channel1, 'received:', args);
        })
        //发送IPC信息
        ipc.sendTo(channel1, 'no callback');
    }
})

• 返回结果示例:

  on channel1 received: "no callback"

举例2（含返回值）:

import {CoreAPI} from '@cutos/core';

CoreAPI.init(null, (result, error) => {
    if (!error) {
    let channel2 = 'channel2';
    let ipc = CoreAPI.getIPC();
    //监听IPC信息
    ipc.on(channel2, (args, respond) => {
        console.log('on ' + channel2 + ' received: ' + JSON.stringify(args));
        respond({sum: args.opt1 + args.opt2})
     })
    //发送IPC信息
    ipc.sendTo(channel2, {opt1: 2, opt2: 2}, (result) => {
        console.log('on ' + channel2 + ' callback: ' + JSON.stringify(result))
    })
    }
})

• 返回结果示例:

  on channel2 received: {"opt1":2,"opt2":2}
  on channel2 callback: {"sum":4}

设备间进程通信举例:

发送方(IP:192.168.1.136)

import {CoreAPI} from '@cutos/core';

CoreAPI.init(null, (result, error) => {
    if (!error) {
        let channel1 = 'channel1';
        //目标IP:192.168.1.149
        let ipc = CoreAPI.getIPC("192.168.1.149");
        //发送IPC信息
        ipc.sendTo(channel1, 'no callback');
    }
});

接收方(IP:192.168.1.149)

import {CoreAPI} from '@cutos/core';

CoreAPI.init(null, (result, error) => {
    if (!error) {
        let channel1 = 'channel1';
        let ipc = CoreAPI.getIPC();
        //监听IPC信息
        let ipcListener = function (args) {
            console.log('on', channel1, 'received', args);
        }
        ipc.on(channel1, ipcListener);
    }
});

• 返回结果示例:

on channel1 received: "no callback"
