最近又遇到定位场景，需要上传经纬度，正好同事写了，我就记录一下方便你我他 ~ ~
今年开始用的kt比较多，所以篇内用的kt，见谅见谅
前情悉知
- 获取当前位置时，需要判断用户是否授权，这里用到的是 XXPermissions
- 未授权会提示用户进行授权，已授权会直接开始调用方法获取经纬度
如何验证获取的定位准确与否，经纬度对不对，可以通过这里直接进行确定
调用方式
//经度var lat = ""//纬度var lon = ""LocationUtils.locationInfo(activity, object : LBSLocationListener {override fun onLocationUpdate(p0: LBSLocation) { lat = p0.longitude.toString()lon = p0.latitude.toString()}override fun onLocationFailed(p0: Int) {lat = "0"lon = "0"}})
LocationUtils
因为是在项目中使用的方法，部分涉及到了前端交互中需要提供的参数，如果不需要的话，自行剔除就好
