小程序怎样向H5界面传递token 等数据

通过路径传递
小程序js

let app = getApp();
Page({
  data: {
    pageUrl: ''
  },
  onLoad(options) {
    realId = options.id;
    tokenId = app.globalData.token;
    this.setData({
      pageUrl: 'https://www.goldcontrol.cn/wxroot/APP/JKZL/jknt/line-simple.html?token=' + tokenId + '&realId=' + realId
    })
  }
})

h5js

<script>
      function getUrlParam(name) {
        //分割参数
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); //构造一个含有目标参数的正则表达式对象
        var r = window.location.search.substr(1).match(reg); //匹配目标参数
        if (r != null) {
          return r[2];
        }
        return null; //返回参数值
      }
      var tokenId = getUrlParam("token");
      var realId = getUrlParam("realId");
      $("#container").attr("src","./canvas.html?token="+tokenId +"&realId="+realId);
 </script>
