uni.postMessage

uni.postMessage是一个用于在H5页面和原生App之间进行通信的方法。它可以在H5页面中使用，通过postMessage方法向原生App发送信息。在H5页面中，可以通过uni.postMessage({ data: { action: 'H5来了' } })来发送信息给原生App。这样原生App就可以通过监听message事件来接收来自H5页面的信息，并进行相应的处理。对于Vue页面，可以在created生命周期中添加window.addEventListener('message', this.handleMessage)来监听message事件，而在beforeDestroy生命周期中移除监听器window.removeEventListener('message', this.handleMessage)，以确保在组件销毁时不再监听message事件。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
