通过wx.getLocation获取当前的位置，但是返回值中altitude一直显示为0，是什么原因呢？ wx.getLocation({ type: 'gcj02', altitude: true, isHighAccuracy:true, success: (res) => { that.setData({ latitude: res.latitude, longitude: res.longitude, speed: res.speed, accuracy: res.accuracy }) qqmapsdk.reverseGeocoder({ location: { latitude: res.latitude, longitude: res.longitude }, success: function (res) { // console.log(res) that.setData({ district:res.result.address_component.district, position:res.result.address_component.street_number }) } }) }, });
