微信游览器跳转跳转APP
1.需要导入微信SDK
//<script src="https://res.wx.qq.com/open/js/jweixin-1.6.0.js"></script>
//npm 安装：npm install weixin-js-sdk --save
//配置如下
  jumpApp: async() => {
    let url = window.location.href
    const platform = uni.getSystemInfoSync().platform
    if (platform === 'ios') {
      url = uni.getStorageSync('bbcIosUrl')
    }
    try {
      const { data } = await http.request({
        url: '/p/wx/jsapi/createJsapiSignature?v='+new Date().getTime(),
        method: 'POST',
        data: url
      })
      wx.config({
        debug: false, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
        appId: data.appId, // 必填，公众号的唯一标识
        timestamp: data.timestamp, // 必填，生成签名的时间戳
        nonceStr: data.nonceStr, // 必填，生成签名的随机串
        signature: data.signature, // 必填，签名，见附录1
        jsApiList: ["onMenuShareAppMessage", "openLocation", 'wx-open-launch-app','checkJsApi','updateAppMessageShareData'], // 必填，需要使用的JS接口列表, 我们这里填个这个就能唤起app了
        openTagList: ['wx-open-launch-app']// 必填，需要使用的JS接口列表，所有JS接口列表见附录2
      })
    } catch (error) {
      console.log('初始化微信SDK出现异常', e)
      return false
    }
    return new Promise((reslove, reject) => {
      wx.ready(function (e) {
        console.log('ready', e);
        reslove(true)
      });
      wx.error(function (err) {
        console.log(err, "微信跳转app报错了");
        reject(false)
      });

    })
  },
