进入页面后点击开发支持→地图JS API
进入地图JS API后点击示例中心,进入界面后拉到底下找到轨迹回放
进入后打开轨迹回放如下图中已有示例,模拟小车的行驶轨迹。其模拟的轨迹为右侧框图的小车模拟位置点, 将自己获取的经纬度点替代上面提到的小车模拟位置点即可验证自己设备输出的GPS位置的准确性。(注意:此页面代码为HTML格式)

启动时会遇到Module not found: Error: Can’t resolve ‘less-loader’ in '文件位置’报错
原因是因为 less 、 less-loader模块未安装,但在中进行使用
解决方法:npm install --save-dev less-loader less
直接安装可能会存在版本太高问题的报错,进行npm run dev时项目无法启动
解决方法:npm install less-loader@5.0.0 -D 可在版本位置选择合适的版本
