微信小程序web-view点击需要返回两次和缓存的问题

在web-view中点击左上角需要点击两次才能返回的问题解决

这是写在h5页面里面的

window.addEventListener('popstate', (event) => {
    
    
  wx.miniProgram.navigateBack();
});
const code = getSearch('code'); // 伪代码，获取查询参数
if (!code) {
    
     // 页面A1
  if (isWeixin()) {
    
    
    // 微信环境
    const redirectUrl = window.location.href + '&code=1';
    window.location.href = 'https://open.weixin.qq.com/connect/oauth2/authorize' + '?appid=' + appId +
    '&redirect_uri=' + encodeURIComponent(redirectUrl) +
    '&response_type=code&scope=snsapi_userinfo' +
    '#wechat_redirect'; // 静默授权伪代码
  } else {
    
    
    alert('当前不是微信环境');
  }
} else {
    
     // 页面A2
  history.pushState({
    
    page: 1}, null, window.location.href);
}

web-veiw路由的缓存问题解决

参考了别人大神的代码

<template>
  <div class="video">
    <web-view :src="webViewUrl" v-if="webViewUrl.length"></web-view>
  </div>
</template>
<script>
export default {
    
    
  data() {
    
    
    return {
    
    
      webViewUrl: "",
    };
  },

  mounted() {
    
    },
  onLoad(option) {
    
    
    // this.webViewUrl = `https://www.hnytbd.com/index.html?equipmentSncode=${
    
    
    //   this.$route.query.code
    // }&r=${Math.random()}`;

    if (wx.getStorageSync("isJournalBack")) {
    
    
      wx.removeStorageSync("isJournalBack");
    }
    let str = "https://www.hnytbd.com/index.html";
    if (JSON.stringify(option) !== "{}") {
    
    
      str += "?";
      for (var i in option) {
    
    
        str += i + "=" + option[i] + "&";
      }
      str = str.slice(0, str.length - 1);
    }
    this.webViewUrl = `${
      
      decodeURIComponent(str)}`;
  },

  onShow() {
    
    
    // this.onLoad();

    if (wx.getStorageSync("isJournalBack")) {
    
    
      let urlTemp = this.webViewUrl;
      this.webViewUrl = "";
      wx.removeStorageSync("isJournalBack");
      setTimeout(() => {
    
    
        this.webViewUrl =
          urlTemp.split("?")[0] +
          "?flag=" +
          Date.parse(new Date()) +
          "&" +
          urlTemp.split("?")[1];
        console.log(this.webViewUrl);
      }, 100);
    }
  },
};
</script>
