    wx.getLocation({
      type: ‘gcj02‘,
      success: function (res) {
        var locationParam = res.latitude + ‘,‘ + res.longitude + ‘1‘
        wx.request({
          url: ‘https://api.map.baidu.com/geocoder/v2/‘,
          data: {
            ak: ‘---------‘,

          method: ‘GET‘,
          success: function (res) {
            console.log(res)
            that.data.city = res.data.result.addressComponent.city.slice(0, -1)
            typeof cb == "function" && cb(res.data.result.addressComponent.city.slice(0, -1))
          },
          fail: function (res) {
            // 重新定位
            that.getCity();
          }
        })
