鸿蒙HarmonyOS 地图定位到当前位置 site查询等操作

应用服务Map使用 地图定位 地点查询及导航 周边查询 点位标记定义等

地图定位 

前提地图已经能正常显示，若不能显示请大家参考之前的那篇如何显示地图的博文

地图相关的api

 module.json5配置权限

"requestPermissions": [{"name": "ohos.permission.LOCATION","reason": "$string:dependency_reason","usedScene": {"abilities": ["EntryAbility"],"when": "always"}},{"name": "ohos.permission.APPROXIMATELY_LOCATION","reason": "$string:dependency_reason","usedScene": {"abilities": ["EntryAbility"],"when": "always"}},{"name": "ohos.permission.LOCATION_IN_BACKGROUND","reason": "$string:dependency_reason","usedScene": {"abilities": ["EntryAbility"],"when": "always"}},{"name": "ohos.permission.INTERNET","reason": "$string:dependency_reason","usedScene": {"when": "always"}},{"name": "ohos.permission.GET_NETWORK_INFO","reason": "$string:dependency_reason","usedScene": {"when": "always"}},{"name": "ohos.permission.CAMERA","reason": "$string:dependency_reason","usedScene": {"abilities": ["EntryAbility"],"when": "always"}}]

确认在AGC中已配置地图权限 这里就不截图了！
