vue2+百度离线地图实现行驶多车辆动态轨迹
效果图
业务代码
实现多多车辆实时轨迹监控，每个10秒监测一次接口，进行动态追加。（前端实现，如果数量庞大的车辆移动，很消耗性能）

接口数据格式
完成改功能效果需要两个接口，①初始化坐标点接口，②增量坐标点接口
①初始化坐标点接口：
[
{
"deviceCode": "37050000001320000090",
"name": "11111111222",
"taskId": null,
"longitude": 113.38011471963698,
"latitude": 23.129711801602145,
"orgId": "00000000-0000-0000-0000-000000000000",
"isOnline": false,
"taskLevel": "5",
"deviceType": 1,
"tracks": null,
"id": "3a07ab99-c4fe-749a-33a9-6cf25e324f76"
}
]
②增量坐标点接口
[
{
"id": "3a07ab99-c4fe-749a-33a9-6cf25e324f76",
"tracks": [
{
"lat": 113.38011471963698,
"lot": 23.129711801602145,
}
],
}
]
有个缺点就是如果数据量庞大会导致浏览器性能消耗严重，因为这里使用了定时器实现，应该有更好的办法实现，
