wx.scanCode({
            scanType:['qrCode'],
            onlyFromCamera: true,//设置只能用相机扫描
            success(res){
              var data=res.result;
  console.log(data);})
如何将这个data数据转为json形式并通过
wx.navigateTo({
                url: '/pages/info/info',
                events: {
                  // 为指定事件添加一个监听器，获取被打开页面传送到当前页面的数据
                  acceptDataFromOpenedPage: function(data) {
                    console.log(data)
                  },
                  someEvent: function(data) {
                    console.log(data)
                  }
                },
                success: function(res) {
                  // 通过eventChannel向被打开页面传送数据
                  res.eventChannel.emit('acceptDataFromOpenerPage', { data: '数据' })
                }
              })
发往另一也页面调用显示
