2、H5传递参数

<web-view
      src="{
       {url}}"
      bindload="webviewOnLoad"
      binderror="webviewOnError"
      bindmessage="onMessage"
    ></web-view>

Page({
      data: {
        src: "https://microapp.bytedance.com/",
      },
      // 小程序后退、组件销毁、分享时，由此函数来接收H5页传过来的参数
      onMessage(options) {
        console.log("onmessage：", options.detail.data);
      },
      webviewOnLoad() {
        console.log("webview 加载成功");
      },
      webviewOnError(e) {
        console.log("webview 加载失败", e);
      },
    });

3、判断 H5 页面是否在小程序 web-view 打开

// isTTWebView 若为 true，则是在头条小程序的 web-view 中打开
    const isTTWebView = navigator.userAgent
      .toLowerCase()
      .includes("toutiaomicroapp");
