浏览器 "桥" 实现

信息

由于浏览器本身就是 WebView 的完整版，并不存在所谓的 jsBridge。但为了保障业务源码逻辑的统一性，我们在浏览器环境下也模拟出一个 jsBridge 概念。本章将为您详细讲解如何基于 @realsee/jsbridge-x 在您自己的代码中实现浏览器 "桥" 。

@realsee/jsbridge-x 的 jsBridge 都是基于 JSBridgeProtocol 与订阅发布者模式实现的，首先，您需要引入 Subscribe 类以及 JSBridgeProtocol 接口。基于 Subscribe 和 JSBridgeProtocol 创建名为 JSBridgeBrowser 的类。

import { Subscribe } from "@realsee/jsbridge-x/lib/shared-utils/Subscribe";
import { JSBridgeProtocol } from "@realsee/jsbridge-x/lib/typings/JSBridgeProtocol";
import { WebViewEventMap } from "@realsee/jsbridge-x/lib/typings/WebViewEventMap";

export class BrowserJsbridge
  extends Subscribe<WebViewEventMap>
  implements JSBridgeProtocol {
  // 在此撰写所需方法
}

接下来，您可以按照 JSBridgeProtocol 接口声明，实现相应方法。

提示

如果您已经安装 @realsee/jsbridge-x ,则可以在 @realsee/jsbridge-x/lib/typings/JSBridgeProtocol.d.ts 声明文件中看到完整的 JSBridgeProtocol 接口声明。 也可以直接点 Interface JSBridgeProtocol 文档说明 查看。 查看文档链接时，可在按需修改版本号，查看所需版本的文档。 https://unpkg.com/@realsee/jsbridge-x**{版本号}**/docs/interfaces/jsBridge.JSBridgeProtocol.html
