小程序map地图通过 MapContext.includePoints 重新设置地图视野，在complete或者success回调中设置地图中心点坐标不生效；

如下：

var mapctx = wx.createMapContext('mymap', this);
mapctx.includePoints({
	points: includepoints,
	padding: [60],
	success: (res) => {
		
	},
	fail(data) {
		console.log('includePoints失败:', data)
	},
	complete(data) {
		mapctx.getCenterLocation({
			success(res) {
				console.log('缩放后地图中心：', res)
				var longitude = that.longitude
				var latitude = that.latitude
				that.setData({
					'longitude': longitude,
					'latitude': latitude,
				})
			},
			complete() {
				var longitude = that.longitude
				var latitude = that.latitude
				that.setData({
					'longitude': longitude,
					'latitude': latitude,
				})
			}
		})
	}
})
