Uniapp WebView Real-Time Interaction Guide

To achieve real-time interaction between uni-app and webview, you can utilize the webview component in uni-app and the postMessage method in JavaScript.

In uni-app, you can use the webview component to load web pages and send messages from uni-app to the webview. By listening to the message event of the webview, you can receive messages sent from the webview.

1. Load a webpage in a uni-app page using the webview component.

<template>
  <view>
    <web-view src="https://example.com" @message="onMessage"></web-view>
  </view>
</template>

1. Define the onMessage method in the methods of the uni-app page to handle the received webview messages.

export default {
  methods: {
    onMessage(event) {
      // 处理接收到的webview消息
      const msg = event.detail.data;
      console.log('Received message from webview:', msg);
      // 实时交互逻辑...
    }
  }
}

1. In a webview, you can use the postMessage method in JavaScript to send messages to uni-app.

// 向uni-app发送消息
window.postMessage('Hello from webview', '*');

1. In the onMessage method in a uni-app page, you can execute real-time interaction logic based on the received message.

The above is the basic implementation of real-time interaction between uni-app and webview. By using the webview component and the postMessage method, bidirectional communication can be achieved between uni-app and webview, enabling real-time interaction.
