1、BroadCast Channel用简单的广播通道实现跨标签页通信
1.1、实现的API：BroadCastChannel接口及其类的构造
2、ServiceWorker用独立的服务上下文代理-实现跨标签页通信
2.2、服务线程ServiceWorker的ServiceWorkerContainer容器接口
在学习全阶班谢老师的关于浏览器跨标签页通信概述及实操的基础上，进一步深入及研究如下：
1、BroadCast Channel用简单的广播通道实现跨标签页通信
属于html的标准、DOM范畴：
// node_modules\typescript\lib\lib.dom.d.ts
// https://developer.mozilla.org/zh-CN/docs/Web/API/Broadcast_Channel_API
// https://html.spec.whatwg.org/multipage/web-messaging.html#broadcasting-to-other-browsing-contexts
1.1、实现的API：BroadCastChannel接口及其类的构造
//接口定义：
interface BroadcastChannel extends EventTarget {
// 返回通道名称(传递给构造函数):Returns the channel name (as passed to the constructor).
readonly name: string;
onmessage: ((this: BroadcastChannel, ev: MessageEvent) => any) | null;
onmessageerror: ((this: BroadcastChannel, ev: MessageEvent) => any) | null;
// 关闭BroadcastChannel对象,将其打开以进行垃圾回收 : Closes the BroadcastChannel object, opening it up to garbage collection.
close(): void;
// 将给定消息发送到此频道设置的其他BroadcastChannel对象.消息可以是结构化对象,例如嵌套对象和数组: Sends the given message to other BroadcastChannel objects set up for this channel. Messages can be structured objects, e.g. nested objects and arrays.
postMessage(message: any): void;
// 定义事件侦听:
addEventListener < K extends keyof BroadcastChannelEventMap > (type: K, listener: (this: BroadcastChannel, ev: BroadcastChannelEventMap[K]) => any, options ? : boolean | AddEventListenerOptions): void;
addEventListener(type: string, listener: EventListenerOrEventListenerObject, options ? : boolean | AddEventListenerOptions): void;
// 销毁事件侦听:
removeEventListener < K extends keyof BroadcastChannelEventMap > (type: K, listener: (this: BroadcastChannel, ev: BroadcastChannelEventMap[K]) => any, options ? : boolean | EventListenerOptions): void;
removeEventListener(type: string, listener: EventListenerOrEventListenerObject, options ? : boolean | EventListenerOptions): void;
}
//类的实例化构造方法的定义：
declare var BroadcastChannel: {
prototype: BroadcastChannel;
new(name: string): BroadcastChannel;
};
1.2、原理：
内部是MessagePort或其数组这一EventTarget，在底层通讯的两侧的端口上，发送方postMessage，接收方监听事件onMessage：
// 此Channel Messaging API接口表示MessageChannel的两个端口之一，允许消息从一个端口发送，并在消息到达的另一个端口进行侦听:This Channel Messaging API interface represents one of the two ports of a MessageChannel, allowing messages to be sent from one port and listening out for them arriving at the other.
//
interface MessagePort extends EventTarget {
onmessage: ((this: MessagePort, ev: MessageEvent) => any) | null;
onmessageerror: ((this: MessagePort, ev: MessageEvent) => any) | null;
// 断开端口连接，使其不再处于活动状态: Disconnects the port, so that it is no longer active.
close(): void;
//
// 通过频道发布消息.传输中列出的对象将被传输,而不仅仅是克隆,这意味着它们在发送端不再可用: Posts a message through the channel. Objects listed in transfer are transferred, not just cloned, meaning that they are no longer usable on the sending side.
//
// 如果传输包含重复的对象或端口,或者消息无法克隆,则抛出“DataCloneError”DOMException的异常: Throws a "DataCloneError" DOMException if transfer contains duplicate objects or port, or if message could not be cloned.
//
postMessage(message: any, transfer: Transferable[]): void;
postMessage(message: any, options?: StructuredSerializeOptions): void;
// 开始调度在端口上接收的消息: Begins dispatching messages received on the port.
start(): void;
// 定义事件侦听:
addEventListener<K extends keyof MessagePortEventMap>(type: K, listener: (this: MessagePort, ev: MessagePortEventMap[K]) => any, options?: boolean | AddEventListenerOptions): void;
addEventListener(type: string, listener: EventListenerOrEventListenerObject, options?: boolean | AddEventListenerOptions): void;
// 销毁事件侦听:
removeEventListener<K extends keyof MessagePortEventMap>(type: K, listener: (this: MessagePort, ev: MessagePortEventMap[K]) => any, options?: boolean | EventListenerOptions): void;
removeEventListener(type: string, listener: EventListenerOrEventListenerObject, options?: boolean | EventListenerOptions): void;
}
declare var MessagePort: {
prototype: MessagePort;
new(): MessagePort;
};
2、ServiceWorker用独立的服务上下文代理-实现跨标签页通信
2.1、说serviceWorker首先需要了解浏览器的导航器navigator
◆ 导航器navigator是用户代理(UA:即浏览器本身对外发布的实例的化身)的状态和标识.它允许脚本查询它并注册自己以进行某些活动；
◆ 导航器navigator是web应用的初始入口，任何web应用都需要首先通过navigator在location地址栏将url在浏览器当前的执行上下文window中进行导入；
◆ 每个导航器navigator都有一个负责渲染的主线程(即渲染容器),亦即当前上下文的window,html就是在主线程中让DOM进行工作的；
◆ 每个导航器navigator的主线程window都唯一对应了1个location地址栏,在当前window上下文中进行导航操作；
◆ 每个导航器navigator还隐式地存在“独立的上下文window”,可供用户代理在各自的安全上下文中用于“创建”register外部的模块module、“安装”module、“调用”module,但它不能直接用于DOM的操作和渲染；
这个导航器navigator的隐式的“独立的上下文window”也是个容器,即serviceWorker,它在创建的同时即会产生1个对应的“外部模块”的控制器controller,由控制器实际在其内部对监听到的客户端的其它安全上下文的消息的收发等；
这个容器serviceWorker是ServiceWorkerContainer类型的接口。
//说serviceWorker首先需要了解浏览器的导航器navigator：
//
// 导航器navigator是用户代理(UA:即浏览器本身对外发布的实例的化身)的状态和标识.它允许脚本查询它并注册自己以进行某些活动 : The state and the identity of the user agent. It allows scripts to query it and to register themselves to carry on some activities.

// 每个导航器navigator都有一个负责渲染的主线程(即渲染容器),亦即当前上下文的window,html就是在主线程中让DOM进行工作的;

// 每个导航器navigator还隐式地存在“独立的上下文window”,可供用户代理在各自的安全上下文中用于“创建”register外部的模块module、“安装”module、“调用”module,但它不能直接用于DOM的操作和渲染,
// :这个导航器navigator的隐式的“独立的上下文window”也是个容器,即serviceWorker,它在创建的同时即会产生1个对应的“外部模块”的控制器controller,由控制器实际在其内部对监听到的客户端的其它安全上下文的消息的收发等.
// :这个容器serviceWorker是ServiceWorkerContainer类型的接口，它有其独立的ServiceWorkerGlobalScope全局作用域，以区别于其它任何渲染主线程的作用域window :
// #
interface Navigator extends NavigatorAutomationInformation, NavigatorConcurrentHardware, NavigatorContentUtils, NavigatorCookies, NavigatorID, NavigatorLanguage, NavigatorLocks, NavigatorOnLine, NavigatorPlugins, NavigatorStorage {
// Available only in secure contexts.
readonly clipboard: Clipboard;
// Available only in secure contexts.
readonly credentials: CredentialsContainer;
readonly doNotTrack: string | null;
readonly geolocation: Geolocation;
readonly maxTouchPoints: number;
readonly mediaCapabilities: MediaCapabilities;
// Available only in secure contexts.
readonly mediaDevices: MediaDevices;
readonly mediaSession: MediaSession;
// 权限也是由导航器navigator来对接其接口的 :
readonly permissions: Permissions;
// serviceWorker容器仅在安全上下文中可用 : Available only in secure contexts.
readonly serviceWorker: ServiceWorkerContainer;
// 导航器是否能共享ShareData数据,也仅在安全上下文中可用 : Available only in secure contexts.
canShare(data?: ShareData): boolean;
getGamepads(): (Gamepad | null)[];
// Available only in secure contexts.
requestMediaKeySystemAccess(keySystem: string, supportedConfigurations: MediaKeySystemConfiguration[]): Promise<MediaKeySystemAccess>;
sendBeacon(url: string | URL, data?: BodyInit | null): boolean;
// Available only in secure contexts.
share(data?: ShareData): Promise<void>;
vibrate(pattern: VibratePattern): boolean;
}
declare var Navigator: {
prototype: Navigator;
new(): Navigator;
};
2.2、服务线程ServiceWorker的ServiceWorkerContainer容器接口
◆ ServiceWorkerContainer容器接口提供了一个对象，将服务线程（ServiceWorker）表示为网络生态系统中的一个整体单元,包括注册、注销和更新服务线程以及访问服务线程及其注册状态的设施 ；
◆ serviceWorker容器仅在安全上下文中可用。
ServiceWorker API的ServiceWorkerContainer容器接口提供了一个对象,将服务线程表示为网络生态系统中的一个整体单元,包括注册、注销和更新服务线程以及访问服务线程及其注册状态的设施 : The ServiceWorkerContainer interface of the ServiceWorker API provides an object representing the service worker as an overall unit in the network ecosystem, including facilities to register, unregister and update service workers, and access the state of service workers and their registrations.
2.3、服务线程ServiceWorker的使用方法和步骤
2.3.1、简单用法---标签页间互传消息
◆ 用导航器的服务容器接口，实例化服务线程的模块的url定义
// 注册 service worker
navigator.serviceWorker.register('sw.js')
.then(() => {
console.log("service worker 注册成功");
});
◆ 实现服务线程的模块的代码功能---基本功能就是“代理”
// 这事注册(创建)的SW模块的实例(ServiceWorkerRegistration extends EventTarget);
// ServiceWorker API接口注册了这个SW服务之后,它就可以用来来控制一个或多个共享相同“源/域”(或安全上下文)的页面的消息(但不能直接操纵DOM) ：
// navigator.serviceWorker.controller.postMessage发的消息message就会汇集到本模块运行时所在的window上下文self :
// 消息是否被加工、加工的消息是否再被发出去,也在这里调度,向某个client.postMessage转发消息 :
var clientsArr = [];
var currentEvent = new MessageEvent('message', null);
self.addEventListener('message', async event => {
console.log('本模块的本质: 是运行时“message事件驱动的线程”, 必须在message消息事件监听处理函数中, 输入/输出(I/O)才生效 :');
console.log('self: 即ServiceWorkerGlobalScope即SW自己独立的全局window对象: ', self);
console.log('self.serviceWorker.scriptURL即:./sw.js就是本模块自身的文件全路径: ', self.serviceWorker.scriptURL.trim());
console.log(event.data, ' : 这是,产生SW模块的上下文window发来的event.data事件携带的消息数据');
console.log(event, ' : 这是event:ExtendableMessageEvent,产生SW模块的上下文window发来的event,被SW在自己的安全上下文中侦听到了,你可以解构其中的信息: ');
currentEvent = event;
for (const key in event) {
const element = event[key];
console.log(key + ' : ', element);
}
if (currentEvent.source.url.trim().endsWith('index.html') &&
(currentEvent.data.to === 'index2.html') // : 条件满足，才提交“事件通知消息” :
) {
clientsArr.push({
'clientName': '页面1',
'urlStr': 'index.html',
'event.origin': currentEvent.origin,
'event.source.url': currentEvent.source.url.trim(),
'event.source.id': currentEvent.source.id,
'event.currentTarget.serviceWorker.state': currentEvent.currentTarget.serviceWorker.state,
'data.value': currentEvent.data.value,
'data.to': currentEvent.data.to
});
console.log('我客制化存取的识别客户端的数组clientsArr: ', clientsArr);
// 首先获取到所有注册了 service worker 的客户端 :
const clients = await self.clients.matchAll();
clients.forEach(function(client) {
if (client.url && client.url.endsWith('index2.html') && !client.focused) {
client.postMessage(event.data.value); // : 向某个client.postMessage转发消息
console.log('符合条件的接收消息的标签页客户端的上下文client : ', client);
}
// client.visibilityState: "visible", client.focused: true //---发送方
// client.visibilityState: "hidden" , client.focused: false //---接收方
})
};
})
◆ 更详细的输出测试：
◆ 可以进一步“条件约束”---接收方、发送方：
2.3.2、进阶用法
◆ 本案用基本的Service Worker和ReadableStream“(只读)可读流”来同时显示下载进度和<img> 标签加载的实时数据。与 fetch() 不一样的是, 图片是用浏览器的native原生的loading行为来progressively“进度化的”渐进式渲染的。且在此过程中，实现了“不透明响应”跨域访问重定向：
serviceWorker渐进式获取并同步加载数据
◆ 进一步在下载过程中“嗅探网络”
下载过程中“嗅探网络”的稳定性：当网络不稳定造成下载中断，将在5秒后自动继续重载；当然，这里未使用“断点续传下载”，若使用后，效果更佳！
serviceWorker静默渐进获取数据且自动避开网络异常
◆ SW的平台支持，在我另外1个博客中有专门的说明：
浏览器Disk Cache磁盘缓存及其协商缓存、及原生App和浏览器实现缓存的差异_pulledup的博客-CSDN博客
