 * 跨端双向通讯桥

 *  网页对 App 发起通讯
 *  通讯策略
 *      1. App 对网页一般为单向通知，无资源管理要求
 *      2. 网页对 App 发起单向通知时，也无资源管理要求
 *      3. 网页对 App 发起单次通讯时，如诺 App 未执行回调，前端将在5分钟后字段释放资源
 *      4. 网页对 App 发起持续性通讯时，应转换为 App 对网页发起通知，通知无资源管理要求（而不是使用轮询或监听，需要手动停止释放资源）
 *      5. 网页对 App 发起通讯，两端具体处理方式如下：
 *          - 如果 callback 有值，App 端在各种情况下，都尽量执行回调，以便于前端更快释放资源
 *          - 如果 callback 无值，即为单向通知，此时 App 无需处理回调（消息提示由 App 端执行）
 *          - 如果 App 出现报错或异常，执行 callback 回调时不传任何内容（不能传空对象或空字符串，直接为空）（错误提醒由 App 执行）
 *          - 如果通讯正常，但是业务为支线流程，例如取消操作，则返回标识表明取消操作（消息提示由网页端执行）
 *  网页对 App 发起通讯操作步骤
 *      1. 【App端】App 注册接收器，用于接收网页通知
 *          在页面打开之前，App 注入方法 linking = function(paramStr) { <Native Code> }
 *      2. 网页业务中 js 发起通讯
