跳转时处理

 const params = {
   url:'hhtp://www.baidu.com?a=1'
 }
  const queryString = Object.keys(params).map(key => `${encodeURIComponent(key)}=${encodeURIComponent(params[key])}`).join('&');
  wx.navigateTo({
    url: `../../toPageView/toPageView?${queryString}`,
  })

webview页面接受参数

<web-view src="{{url}}" />

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad(options) {
    console.log(options);
    let obj = decodeURIComponent(options.url)
    console.log(obj);
    this.setData({
      url: obj
    })
    console.log(this.data.url);
  },
