公司大佬叫我研究下HomeKit，準(zhǔn)備和公司的產(chǎn)品對(duì)接上萧锉，正常流程肯定不行（需要蘋(píng)果認(rèn)證才能），所有就要學(xué)習(xí)homeBridge這個(gè)神來(lái)之筆。

homeBridge是一個(gè)大神開(kāi)發(fā)了神器茴丰，使用nodejs平臺(tái)，破解了蘋(píng)果的HomeKit的那個(gè)什么協(xié)議天吓，可以將自己的設(shè)備添加到蘋(píng)果app(家庭)上面贿肩，然后實(shí)現(xiàn)控制自己的設(shè)備。像小米的很早就實(shí)現(xiàn)了龄寞，俺們公司小不能比汰规。

第一步：了解并下載homeBridge

https://github.com/nfarina/homebridge

首先你需要打開(kāi)下面的鏈接，然后好好的看一遍或者幾遍
https://github.com/nfarina/homebridge
并下載homeBridge

第二步：可能遇到的問(wèn)題

問(wèn)題1：

$ homebridge
No plugins found. See the README for information on installing plugins.

沒(méi)有找到插件物邑，第一步的網(wǎng)頁(yè)有解釋?zhuān)阈枰螺d一個(gè)插件溜哮，或者像我一樣自己開(kāi)發(fā)一個(gè)，當(dāng)然我開(kāi)發(fā)的只針對(duì)本公司的設(shè)備

問(wèn)題2：

$ homebridge
Couldn't find a config.json file [snip]

沒(méi)有找到config.json文件色解，你需要?jiǎng)?chuàng)建一個(gè)config.json文件茂嗓，然后將這個(gè)文件放到. homeBridge里面
這時(shí)候你可能迷糊了，. homeBridge在哪科阎？
為了詳細(xì)述吸，我要開(kāi)始圖文解析了：

打開(kāi)Finder

image.png

在上圖kk文件下，你的就是mac名稱(chēng)锣笨，同時(shí)按下 command+shift+. 顯示隱藏文件蝌矛，就可以看到. homeBridge了

image.png

問(wèn)題3：config.json怎么寫(xiě)

直接復(fù)制吧然后放到. homeBridge下

{
    "bridge": {
    "name": "Homebridge",
    "username": "CC:22:3D:E3:CE:30",
    "port": 51825,
    "pin": "111-11-122"
    },
    
    "description": "This is an example configuration file with pilight plugin.",

    
  "platforms": [
    {
      "platform": "SamplePlatform",
      "sid": ["6409802da3ca"],
      "password": ["1234567890123456"]
    }]
}
復(fù)制到這兒
platform：為平臺(tái)的名稱(chēng)，后面需要注冊(cè)與這兒的名稱(chēng)保證一樣票唆。

第三步：開(kāi)始創(chuàng)建自己的插件

如果你已經(jīng)完成前兩步朴读，執(zhí)行命令會(huì)出現(xiàn)錯(cuò)誤

image.png

剛才在config.json寫(xiě)的 "platform": "SamplePlatform"平臺(tái)下未注冊(cè)任何插件，這時(shí)候你已經(jīng)配置好所有前提條件走趋，剩下的就是最后一步衅金，創(chuàng)建一個(gè)插件

1：創(chuàng)建index.js

進(jìn)到homeBridge所在的目錄：/usr/local/lib/node_modules
然后創(chuàng)建一個(gè)文件夾homebridge-sampleplatform

image.png

在文件下創(chuàng)建index.js文件

//deviceSwitch里是操作設(shè)備的命令
var kkDeviceApi = require(__dirname + '/deviceSwitch');
var Accessory, Service, Characteristic, UUIDGen;
var that;  //指向SamplePlatform 初始化內(nèi)部this

module.exports = function(homebridge) {
  console.log("homebridge API version: " + homebridge.version);
  // Accessory must be created from PlatformAccessory Constructor
  Accessory = homebridge.platformAccessory;

  // Service and Characteristic are from hap-nodejs
  Service = homebridge.hap.Service;
  Characteristic = homebridge.hap.Characteristic;
  UUIDGen = homebridge.hap.uuid;
  
  // For platform plugin to be considered as dynamic platform plugin,
  // registerPlatform(pluginName, platformName, constructor, dynamic), dynamic must be true
  homebridge.registerPlatform("homebridge-sampleplatform", "SamplePlatform", SamplePlatform, true);
};

// Platform constructor
// config may be null
// api may be null if launched from old homebridge version
function SamplePlatform(log, config, api) {
  log("SamplePlatform Init");
  this.log = log;
  this.config = config;
  this.kkAccessories = [];
  that = this;
  console.log('this指向1=',this);
  if (api) {
      // Save the API object as plugin needs to register new accessory via this object
      this.api = api;
      // Listen to event "didFinishLaunching", this means homebridge already finished loading cached accessories.
      // Platform Plugin should only register new accessory that doesn't exist in homebridge after this event.
      // Or start discover new accessories.
      this.api.on('didFinishLaunching', function() {
          this.log("DidFinishLaunching");
          kkDeviceApi.DeviceControl.DeviceDiscovery();
      }.bind(this));
  }
}
/*---------------為SamplePlatform添加方法------------*/
SamplePlatform.prototype = {
    //發(fā)現(xiàn)設(shè)備
    onDevice: function (devInfo) {

        if (serviceObj === null) {

3：在app上添加平臺(tái)

這時(shí)候會(huì)出現(xiàn)一個(gè)二維碼和pin碼

image.png

手機(jī)打開(kāi)HomeKit添加配件，掃描二維碼或者pin碼瞒渠，生成一個(gè)平臺(tái)

在deviceSwitch.js文件中會(huì)掃描局域網(wǎng)設(shè)備良蒸，然后調(diào)用index.js中的onDevice()方法將設(shè)備添加到平臺(tái)下，app會(huì)自動(dòng)生成一個(gè)開(kāi)關(guān)或者其他類(lèi)型的設(shè)備
