wx.scanCode扫码成功后应直接跳转指定页面，而不是先返回扫描入口页再跳转指定页面

      wx.scanCode({
        success: (res) => {
          const result = res.result;
          wx.navigateTo({
            url: '/pages/store/stock/stock?id=' + id + '&tiaoma=' + result
          })
        },
        fail: (res) => {
          wx.showToast({
            title: '扫描失败',
            icon: 'fail',
            duration: 2000
          })
        },
      })
